About Science Frontiers

Science Frontiers is the bimonthly newsletter providing digests of reports that describe scientific anomalies; that is, those observations and facts that challenge prevailing scientific paradigms. Over 2000 Science Frontiers digests have been published since 1976.

These 2,000+ digests represent only the tip of the proverbial iceberg. The Sourcebook Project, which publishes Science Frontiers, also publishes the Catalog of Anomalies, which delves far more deeply into anomalistics and now extends to sixteen volumes, and covers dozens of disciplines.

Over 14,000 volumes of science journals, including all issues of Nature and Science have been examined for reports on anomalies. In this context, the newsletter Science Frontiers is the appetizer and the Catalog of Anomalies is the main course.

... Issue Sourcebook Project Sourcebook Subjects Space Spume The celestial pot seems to have boiled over "in the beginning." New surveys of the galaxies suggest that they are mostly located on the surfaces of bubbles, not as we thought for so long distributed uniformly throughout the cosmos, the expanding debris of the Big Bang. If further surveys confirm a bubbly universe, the "conventional explanations for the evolution of large-scale structure in which gravity played a dominant role may have to be modified or abandoned." To explain the bubbles, a new scenario has Big Bang #1 creating a population of uniformly distributed, extremely massive stars, which eventually burned out and exploded in a crescendo of supernovas. One stellar detonation stimulating adjacent giant stars to explode in a chain reaction. The bubble-like shock waves expanding outward from these explosions stimulated the condensations of the stars we now see in the heavens. Naturally, these stars and galaxies are concentrated on the surfaces of the shock wave bubbles. (Anonymous; "New 3-D Map Shows the Cosmos with a 'Bubble Bath' Appearance," Baltimore Sun, January 5, 1986.) Comment. The space bubbles are mapped using redshifts as measurements of distance. As all-too-frequently asserted in this book, some redshifts may not be distance yardsticks, in which case these theoretical bubbles would burst. As the structures of the cosmos and the subatomic worlds become more and more foreign to everyday experience, we have to ask whether such bizarre constructions may not be the consequence of incorrect physical theories, such as Relativity, the ...

... sudden increase of wind speed causing excessive spray. By 1715 GMT, the vessel was totally surrounded by completely random movements of light as far as the eye could see. The onset of this phenomenon was so rapid, not to say eerie, that the Master was called to the bridge to witness the event. For the next 15 minutes the sea was at a height of activity, displaying several systems of the most unusual bioluminescence. The most significant of these were what appeared to be Phosphorescent Wheels, which, although they did not seem to rotate, originated from a central hub and spread out rings in rapid succession, forming concentric circles. This was pointed out by many of those who observed them as being similar to the instance of a stone being dropped into a quiet pond and causing waves to spread out. In this case each wave crest was a band of fantastic light. Each wheel would last for a couple of minutes, continually flashing out bands of light as though a transmitter was located at its centre. Wheels could be observed in all directions. At the same time systems of moving parallel bands could be observed, again travelling in totally random directions with respect to each other and passing off into the distance, only to be followed by another set." The complexity of the display was so great that it confused the eye. Of particular interest was the fact that the centers of the wheels seemed to keep pace with the ship. Sometimes parallel bands of light were seen emanating from the side of the vessel itself, as if it was a center of one ...

The outer atmospheres of these planets act like radio lasers, which store radio energy and then release it suddenly when stimulated by weaker solar signals. The earth's laser operates between frequencies of 50 and 600 kilohertz. Its emissions are known as the "auroral kilometric radiation" or AKR. While some of these terrestrial emissions are spontaneous, others are stimulated by Type-III solar radio bursts. The newly discovered Jovian laser operates at hectometric wavelengths and is also triggered by the solar radio bursts. (Calvert, W.; "Triggered Jovian Radio Emissions," Geophysical Research Letters, 12:179, 1985.) Comment. Earth and Jupiter thus act like radio transponders, releasing large bursts in response to small solar stimuli. The role of electricity in the history of the solar system is only beginning to be appreciated. Of course, the radio lasers mentioned above are not very powerful, but what might have occurred during the formative stages of the solar system? Could electromagnetic forces have been more important then than they are now? In this regard, note that electrical forces seem to be strongly involved in the dynamics of Saturn's rings. And Saturn's rings themselves may resemble a miniature solar system in the accretion phase. From Science Frontiers #40, JUL- ...

The authors of this article stess the pitfalls of using data handed down verbally from generation to generation. With these caveats, they reproduce an Indian tradition originally set down by Judge James Swan back in 1888: "' A long time ago,' said my informant, 'but not at a very remote period, the water of the Pacific flowed through what is now the swamp and prairie between Waatch village and Neeah Bay, making an island of Cape Flattery. The water suddenly receded leaving Neeah Bay perfectly dry. It was four days reaching the lowest ebb, and then rose again without any waves or breakers, till it had submerged the Cape, and in fact the whole country, excepting the tops of the mountains at Clyoquot. The water on its rise became very warm, and as it came up to the houses, those who had canoes put their effects into them, and floated off with the current, which set very strongly to the north.'" The authors of the present article wonder if the above could be an account of a massive tsunami! They admit that the 4-day recession is inconsistent with tsunami action and that the warm water is hard-to-explain. The height reached by the inundation -- some 400 meters -- is also incredible.

Recently, three "delayed choice" experiments have been consummated in physics labs. In such experiments, the result depends upon what the observer tries to measure; viz., light as particulate-in-nature or light as wave-like-in-nature. The funny thing is that it doesn't matter when the experimenter decides what to measure; he can do this months before the experiment or even afterwards! The effect of the choice is the same -- before or after. Now that is weird! But everyone believes it because a theory for it exists.

Recently, several laboratories have been trying to determine if the human mind can affect random physical events, such as radioactive decay. "Surprisingly, the PK effect appears quite independent of physical variables, such as the distance or the complexity of the random generator. The subjects succeed by aiming at the result, regardless of the intermediate steps required to reach this result.

R. Lynds, of Kitt Peak National Observatory, estimates that the arcs are as luminous as 100 billion suns. The nice circularity of the arcs is perplexing; and it is stated that nothing like them has been reported before. The arcs might be incandescent gas, but many astronomers opt instead for swaths of bright young stars. Spectroscopic tests will decide this point. It has been difficult to conceive of an origin for the arcs. Are they blast waves or the results of tidal action between galaxies? No one knows, for all suggestions seem flawed. Something out there not only manipulates stupendous amounts of mass and energy but also does it with a draftsman's compass. (Anderson, Ian; "Astronomers Spot the Biggest Objects in the Universe," New Scientist, p. 23, January 15, 1987.) Comment. In the interest of accuracy, it should be noted that some superclusters of galaxies are larger than the arcs.

Science Frontiers ONLINE No. 38: Mar-Apr 1985 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Two Snowflake Anomalies Rarely is there anything in the scientific literature suggesting that anything about snowflakes could possibly be mysterious. Surprisingly, two articles on snowflake anomalies have appeared recently. To form at all above -40 F, snowflakes supposedly require a solid seed or nucleus around which ice can crystallize -- or so scientists have assumed for many years. It was long believed that airborne dust, perhaps augmented by extraterrestrial micrometeoroids, served as the necessary nuclei. But cloud studies prove that there are about a thousand times more ice crystals than dust nuclei. Now, some are convinced that bacteria blown off plants and flung into the air by ocean waves are the true nuclei of atmospheric ice crystals. Remember this the next time you tast a handful of snow! (Carey, John; "Crystallizing the Truth," National Wildlife, 23:43, December/ January 1985.) Comment. The possibility that the fall of snow and all other forms of precipitation is largely dependent upon bacter-ia brings to mind the Gaia Hypothesis; that is, all life forms work in unison to further the goals of life. The second item is from Nature and is naturally more technical. After reviewing the great difficulties scientists are having in mathematically describing the growth of even the simplest crystal, the author homes in on one of the fascinating puzzles of snowflake growth: "The aggregation of particles into a growing surface will be determined exclusively by local ...

The spectacular reentry of the Space Shuttle Discovery was observed by many Texans in the pre-dawn skies. Among these were Ben and Jeannette Killingsworth. As they observed the Space Shuttle streak across the sky, "they both heartd an unmistakable 'swishing noise' as it passed south of their rural Galveston County home. The sonic boom came several minutes later -- but the swishing sound occurred simultaneously with the visual apparition....Ben graphically described the sounds as 'like a skier coming down a slope,' but with a rapid fluctuation in loudness, 'about two or three hertz.' Jeannette compared the faint sound to the noise made by a fast boat as it slaps across waves on a choppy lake. 'But there was no motor noise,' she added, 'just a sound like repeated puffs of air through your mouth.'" Oberg points out that the mysterious Space Shuttle sounds are basically the same as the anomalous swishes and whizzes attributed by some to meteors. So far, few scientists have accepted meteor sounds as real, preferring to label them "psychological." But now that the Space Shuttles are known to generate similar anomalous sounds, perhaps scientists will install instruments along their well-known reentry paths and find out what is really happening.

As is usual on an 'all aft' ship, you become 'deaf' to the constant background noises, but I gradually became aware that the pulses of light seemed to match those of the main engine's throb, that is, about two per second. The radar (3 -cm radar, running on the 24 n. mile range), and the echo-sounder (indicating a water-depth of about 35 fathoms), were switched off in turn to see if any change was discernible, but there was not. "However, at about this time, the ship passed a localized revolving system, distance off appeared to be about 150 m. My impression was that of a catherine wheel revolving and casting out waves in an angular motion, as shown in the second sketch. How many spokes it had I'm not sure owing to the speed of the pulsations, but I think that there were at least three.

It is at the Moho that seismic wave velocities change abruptly. There is something there, but no one knows just what. At the recent Second International Symposium on Deep Seismic Reflection Profiling of the Continental Lithosphere, a lot of doubts about the stability and character of the Moho surfaced. Under the North American Cordillera, which runs from Alaska to Mexico, the Moho is flat, continuous and oblivious to the faults, terrane plastering, mountain "roots," and the geological phenomena above it. In other areas, though, several Mohos are stacked up. Some Mohos are discontinuous, jumping from one depth to another. Others are strongly influenced by overhead geological structures. Gone is the neat, so simple Moho figured in all the textbooks. (Barton, Penny; "Deep Reflections on the Moho," Nature, 323:392, 1986.

On August 17, the lake turned reddish brown, indicating that it had been stirred up somehow. Although Lake Monoun is in a volcanic crater, chemical analysis of the water found little of the sulphur and halogens normally associated with volcanic action. However, the analysis did find a tremendously high level of bicarbonate ions, which form from the dissociation of carbon dioxide. One theory is that an earthquake disturbed the carbonate-rich deep water of the lake, which as it rose to the surface and lower pressures, released huge volumes of carbon dioxide -- something like opening a soda bottle. The resulting wave of water and cloud of gas caused the deaths and devastation. If there had been some nitric acid in the cloud, the burns could be accounted for.

One of the latest theoretical models of the rings has them composed of balls of hard ice, which interact through mutual collision and are herded by the gravitational caresses of small moons. The successes of this model have been tempered by the fact that it also implies that Saturn's rings are very young. "Theorists would have no problem with a broad, featureless disk surviving the 4.5 billion years since the early days of the solar system, but features such as spiral density waves are clear evidence that satellites, including the profusion of small ones found near the rings, are draining angular momentum from the rings. The satellites should be spiraling outward into ever larger orbits as they gain angular momentum, and the A-ring should collapse inward into the B-ring in just 100 million years as its particles lose angular momentum."

The effect is sometimes quite dramatic. There are accounts of a 'low roar' as the bands of breaking waves, 'walls of white water,' pass a vessel. The bands are sometimes visible from aircraft, on ships' radar and are observed from satellites. In the Bay of Biscay 'boils' have been reported on the sea surface in the calm zones, and appear to be related to pulses of nutrients from the thermocline." These surface phenomena are truly delightful and almost always the consequence of internal waves interacting with the surface. The great bulk of the referenced report is concerned with sonar observations of internal waves and their effects along the coast of Scotland.

"If you chop into a tree, you can see that adjacent trees put out an electrical pulse," said Wagner. "This indicates that they communicated directly."

... the velocities of the planets do in the solar system. This observation is anomalous itself, because it seems that the laws of orbital motion have been violated. We will save this anomaly for another day, the one we are after now is called: The Winding Dilemma. N. Comins and L. Marschall elaborate as follows: "Stars closer to the center of a spiral galaxy don't have as far to go to complete an orbit as stars located farther from the center. Thus, inner stars should orbit more frequently than outer stars, resulting in a spiral that gradually winds up as the galaxy ages. But observations of spiral galaxies at various distances -- and thus at different stages in their evolution -- have shown that this is not the case. Astronomers believe density waves, stochastic star formation, or perhaps a combination of both processes may sustain or regenerate the spiral pattern." Density waves have recently been applied to explain the spiral rings of Saturn, and now to the arms of spiral galaxies. The density waves are thought to stimulate the condensation of bright new stars as they move through space. A good analogy is the bioluminescent wake of ship in tropical waters. The density waves in a galaxy maintain the spiral pattern with new stars, while the old stars die out (in much less time than it takes for them to orbit the hub) as they orbit out of the spiral pattern. Postulating density waves just raises more questions, as is often the case in science. What causes the density waves? Theory says that the density waves should ...

Of course, we recognize that whales and other cetaceans also seem to "talk" to one another, and that other animals employ their sense of smell for relaying messages. But most of us do not realize that lowly fireflies congregate to communicate en masse, with untold thousands of individuals cooperating in huge synchronized light displays. In reading some of the descriptions of these great natural phenomena, one recalls the light displays used to communicate with the aliens in the movie Close Encounters of the Third Kind . J. Buck has been studying flashing fireflies for over half a century. In fact, his first review paper was published in 1938. Buck has now brought that paper up to date in the current Quarterly Review of Biology with a 24page contribution. It is difficult to do justice to this impressive work in a newsletter. Our readers will have to be satisfied with a mere two paragraphs, in which Buck summarizes some of the incredible synchronies.

This altered rock, being lighter than that surrounding it, may slowly rise through it, eventually forming undersea mountains. (Monastersky, Richard; "Novel Mountains and Chimneys in the Sea," Science News, 134:333, 1988.) Comment. This all sounds pretty speculative, but those mountains had to come from somewhere. Perhaps the serpentinite mountains are just one manifestation of a larger phenomenon: the chaotic slithering and popping up and down of crustal material. The following is from New Scientist: "Geophysicists in California and Illinois say that they have found the Earth's "missing" crust by analyzing shock waves from earthquakes to determine the chemical composition of the Earth's interior. If the researchers are correct, then the view of the interior of the Earth that scientists have previously accepted is wrong.

Here's what happens: "A dish, thinly spread with a lightly colored liquid, sits quietly for a moment after its preparation. The liquid is then suddenly swept by a spontaneous burst of colored centers of chemical activity. Each newly formed region creates expanding patterns of concentric, circular rings. These collide with neighboring waves but never penetrate. In some rare cases rotating one-, two-, or three-armed spirals may emerge. Each pattern grows, impinging on its neighboring patterns, winning on some fronts and losing on others, organizing the entire surface into a unique pattern. Finally, the patterns decay and the system dies, as secondary reactions drain the flow of the primary reaction." From this starting point, the implication is made that all manner of biological "reactions" are analogous and therefore reducible to nought but physics and chemistry. Some examples given of self-organizing biological phenomena are: (1 ) the sequencing of amino acids into selfreplicating structures; (2 ) slime-mold organization; and (3 ) the origin of the lens structure of the firefly.

For several months, we have had in our possession a paper from Nature, by J. Cairns, of Harvard, plus some passionate correspondence stimulated by the paper. Now that the circle-forming sheep have provided a good introduction, we will jump into the fray, too. Basically Cairns (in Nature) and B. H. Hall (in Genetics ) say that organisms can respond to environmental stresses by reorganizing their genes in a purposeful way. Such "directed mutation" shifts the course of evolution in a nonrandom way. Such a conclusion was like waving a red flag in front of the evolutionists. R. May, at the University of Oxford, complained, "The work is so flawed, I am reluctant to comment." On the other side, a University of Maryland geneticust, S. Benson, comments, "Many people have had such observations, but they have problems getting them published." Our template in this discussion is an article by A.S . Moffat in American Scientist. She says, "The stakes in this dispute are high, indeed. If directed mutations are real, the explanations of evolutionary biology that depend on random events must be thrown out. This would have broad implications. For example, directed mutation would shatter the belief that organisms are related to some ancestor if they share traits. ...

This title is apparently more palatable to mainstream science than "Mental Influence on Electronic Devices" or "Affecting Cascading Spheres with Thought Waves." Nevertheless, most of the experimental work is in these two areas. As parapsychological research goes, the Princeton work is of the highest scientific quality. In the first category, subjects (called operators in the report) were asked to influence the pulses produced by a Random Event Generator (REG). The REG was actually an electronic noise source coupled with circuits that created random positive and negative pulses. The operator mentally tried to increase or decrease the number of counts, or generate baseline data for experiment control. After 33 different operators and over 250,000 trials, there appeared a small but statistically significant indication that the operators were actually able to influence the equipment. Also interesting is the fact that each operator had a private "signature"; that is, individual cumulative deviation graphs (like the one shown) had typical shapes for each operator.

Since neither probe flew directly over the pole, the complete scene has to be created by 'stretching' a series of photographs taken from the side as Saturn rotated, then fitting them into a polar projection." The straight sides of the hexagon are each about 13,800 kilometers long. The entire structure rotates with a period of 10h 39m 24s, the same period as that of the planet's radio emissions, which is assumed to be equal to the period of rotation of Saturn's interior. The hexagonal feature does not shift in longitude like the other clouds in the visible atmosphere. The pattern's origin is a matter of much speculation. Most astronomers seem to favor some sort of standing-wave pattern in the atmosphere; but the hexagon might be a novel sort of aurora. More extreme speculation has Saturn's radio emissions emanating from the hexagon (something we can see and which has the right rotation period) rather than from the planet's interior (something we cannot see).

Heavy rain began to pelt the ship, and a furious wind sprang up out of nowhere. Squalls were nothing new to the Marques , one of 39 tall ships participating in a transatlantic race. But as a precaution, Stuart Finlay, the seasoned 42-year-old American captain of the ship, shortened the sails. The Marques was carrying a crew of 28 - half of whom were under 25. At the helm, Philip Sefton, 22, fought the angry waves that now confronted them. "Suddenly a heavy gust of wind pushed the Marques down on its starboard side. At the same instant 'a freakish wave of incredible force and size,' as Sefton later described it, slammed the ship broadside, pushing its masts farther beneath the surging water. A second wave pounded the ship as it went down. The Marques filled with water and sank in less than one minute. Most of the crew were trapped as they slept below deck.

Practically speaking, this means that above this layer seismic waves travel at a markedly different velocity than they do below it. This discontinuity is so widespread, occurring beneath all of the continents, that it has received a special name: the Conrad Discontinuity. Ordinarily, a geophysicist would expect to find a significant change in rock type when drilling through such a strong discontinuity. It was widely expected that, at the Conrad Discontinuity, drillers would find the granitic rocks typical of the continents changing suddenly into basalt, which is thought to make up the lower reaches of the earth's crust. However, when Soviet drills pierced the Conrad Discontinuity below the Kola Peninsula, they found no such switchover to basalt at all. In fact, they hadn't even found it when they penetrated to 12 kilometers. This was a shocker. Now, no one knows what the Conrad Discontinuity represents. It doesn't signal a change in rock type; neither is there a fault or boundary of any kind. It is important to find out what is wrong here, because much of modeling of the unseen structure of the earth's crust depends upon a realistic interpretation of seismic records.

It turns out that Alfven has made many correct scientific predictions. (He even shared a Nobel Prize in 1970.) But, as S.G . Brush has related in a detailed article in Eos, being correct is not the same as being accepted. "According to some scientists and philosophers of science, a theory is or should be judged by its ability to make successful predictions. This paper examines a case from the history of recent science - the research of Hannes Alfven and his colleagues on space plasma phenomena - in order to see whether scientists actually follow this policy. Tests of five pre-dictions are considered: magnetohydrodynamic waves, field-alligned (' Birkeland') currents, critical ionization velocity and the existance of planetary rings, electrostatic double layers, and partial corotation. It is found that the success or failure of these predictions had essentially no effect on the acceptance of Alfven's theories, even though concepts such as 'Alfven waves' have become firmly entrenched in space physics. Perhaps the importance of predictions in science has been exaggerated; if a theory is not acceptable to the scientific community, it may not gain any credit from successful predictions." Brush concludes that the continuing resistance to Alfven's work is due to the widely held opinion that his theory is not plausible; that is, it does not conform to the dominant paradigm.

When Mariner 10 flew past Mercury in 1974, its camera eye reinforced the baked-cinder model. To everyone's surprise, recent radar images obtained with powerful earth-based antennas, revealed a highly reflective patch at Mercury's north pole. Could it be ice, for ice reflects radar waves well? Quite possibly, for when Mercury's polar temperatures are calculated, away from the sun's direct glare, they plunge to -235 F. This means that some of the water vapor in the planet's thin atmosphere might freeze out in the poles, creating ice or frost caps. Wouldn't Mariner 10 have seen such a remarkable deposit? Not necessarily, for the spacecraft viewed only half the planet and, if the 640 x 300-kilometer ice patch were covered with dust, it could have been invisible to the camera. But it would still be a bright patch on terrestrial radar scopes, because radars see through thin dust layers.

Some models of the cosmos predict that another such phase change may occur when photons suddenly acquire mass. Grone and Sher have sketched the effects on terrestrial civilization: "The most dramatic effect would be the elimination of all static electric and magnetic fields over a range greater than 1 cm, and the elimination of all electromagnetic radiation with frequencies smaller than a few hundred gigahertz. We have shown that there would be relatively little impact on atomic structure and on solar radiation. The absence of electrostatic fields would force a redesign of current power plants (to use smaller solenoids); the absence of radio and television waves would force a much greater use of cables. The elimination of solar and geomagnetic fields would have a significant meteorological impact.

Zito, from Lockheed, thinks these flashes occur when energetic electrons are emitted from freshly fractured surfaces. Lunar rocks cracking under stress might very well produce flashes visible from earth. Zito also states that newly fractured rocks emit a curious burst of radio waves in the frequency range of 900-5 ,000 Hertz. (Eberhart, J.; "Does the Moon Spark Like a Life-Saver?"

Science Frontiers ONLINE No. 84: Nov-Dec 1992 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects The Florida Rogue Wave Very little has appeared in the scien-tific literature about the huge wave that crashed ashore at Daytona Beach, Florida, on July 3, 1992. Apparently, the scientific community is happy with the landslide explanation, but there may have been a different sort of disturbance. First, the basic data: "A wall of water as much as 18 feet high rose out of a calm sea and crashed ashore, smashing hundreds of vehicles parked on the beach and causing 75 minor injuries, officials and witnesses said. "An undersea landslide apparently caused the 27-mile-long rogue wave late Friday night, a federal seismologist said yesterday." The seismologist cited, F. Baldwin from the U.S . Geological Survey, estimated that the wave was 18 feet high and 250 feet wide. (Anonymous; "Rogue Wave Smashes into Beach," Hawaii Tribune-Herald , July 5, 1992. Cr. H. DeKalb.) Rumors of a falling object. The landslide theory sounds good, but there have been rumors that another phenomenon was involved. B. Stein, of Orlando, has reported the testimony of a boater, who was far offshore at the time: ". .. the boater came forward with the information that, shortly before the time of the wave, he was in his boat about eight miles offshore. He watched as a distant object approached across the sky ...

We now have a bit more to report, although no one seems to have any answers. "The North Atlantic is getting rougher -- much rougher. In the mid-1980s average waves in the ocean were 25 per cent higher than during the 1960s. More recent studies show that by the end of the 1980s the tops of the waves were 50 per cent higher, as measured by both instruments and estimated by sailors. .. .. . "The cause of the increasing choppiness of the waters of the North Atlantic is unclear. Waves are whipped up by strong winds, yet there has been no corresponding increase in wind speeds. [S .] Bacon believes that a clue may lie in the persistence of winds from a certain direction." (Anonymous; "Making Waves in the North Atlantic," New Scientist, p. 10, August 29, 1992.)

Science Frontiers ONLINE No. 87: May-Jun 1993 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Giant impact-wave deposit along u.s . east coast Along the shore from North Carolina to Maryland and also into Chesapeake Bay, deep-sea drillers have charted the Exmore Boulder Bed. No minor deposit this; it is is over 60 meters thick in places and covers more than 15,000 square kilometers. In the bed are found boulders (up to 2 meters in diameter), cobbles, pebbles, and traces of tektite glass and shocked quartz. The youngest microfossils date from the Eocene, and argon dating of the ejecta yield a date of 35.5 million years, which correlates with the North American tektite strewn field. C.W . Poag et al interpret this boulder bed as follows: "On the basis of its unusual characteristics and its stratigraphic equivalence to a layer of impact ejecta at Deep Sea Drilling Project (DSDP) Site 612 (New Jersey continental slope), we postulate that this boulder bed was formed by a powerful bolidegenerated wave train that scoured the ancient inner shelf and coastal plain of southeastern Virginia. The most promising candidate for the bolide impact site (identified on seismic reflection profiles) is 40 km north-northwest of DSDP Site 612 on the New Jersey outer continental shelf." (Poag, C. Wylie, et al; "Deep Sea Drilling Project Site 612 Bolide Event: New Evidence of a Late Eocene Impact-Wave Deposit and a Possible Impact Site, U ...

... Science Frontiers ONLINE No. 88: Jul-Aug 1993 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Seashore Seiches At many spots around the world, sealevel rises and falls with periods of only a few minutes -- much shorter than the common semidiurnal tides and much longer than wind-generated waves. These oscillations of the water surface are termed "seiches." Two fundamentally different kinds of seiches have been noted in the recent literature. The first variety is transitory and can be set into motion by weather disturbances and earthquakes. The second is permanent and a bit more mysterious. Let's take transitory seiches first September 17, 1992. Anglesey, England. At about 0700 in the morning: "I was on the beach at Trearddur on western Anglesey, when an acquaintance drove down the beach towing a fishing boat. He launched the boat in about six inches of water and we then engaged in conversation for a couple of minutes. Turning to the boat, we were amazed to find that it was high and dry about 20 metres from the water's edge. Small flatfish, mainly immature brill, could be seen stranded and flapping in the wet sand. About a minute later, the sea started to return and quickly rose up the beach beyond where the boat had originally been launched. An hour later, the oscillation in sea level was still taking place. I determined that the period was just over three minutes and the amplitude just under one metre, the latter measured with reference to a half-submerged ...

... craters, iridium layers, and tektite deposits. Even so, one necessary consequence of 70% of the large impacts has been neglected until recently: the giant tsunamis and marine incursions that must have swept over the coasts of the continents following impacts at sea. This oversight is now being rectified. 100,000 BP. The South Pacific. A longstanding geological enigma of the New South Wales coastline is the curious distribution of sand dunes. Those headlands less than 40 meters high have lost most of their dunes, leaving only raw, unweathered rock. On the other hand, the higher headlands have retained these dunes. Australians B. Young and T. Bryant hypothesize that a tsunamis 40 meters high swept the lower headlands clean about 100,000 years ago. They can even plot the incoming wave's direction, because a few remnants of the coastal dunes still cling to the southwest corners of the headlands along the NSW coast south of Newcastle. In their scenario, the tsunamis came from the northeast, smashed into the Solomons, southeastern Australia, and northeastern New Zealand. The Great Barrier Reef protected northeastern Australia from the full force of the wave. Young and Bryant favor a Hawaiian landslip as the initiator of the tsunamis, but acknowledge that an asteroid impact could also have done the job. If the wave began near Hawaii, it would initially been about 375 meters (about mile) in height.

This night on a cattle ranch in South Dakota, L. Hasselstrom was dazzled by waves of blue auroral light sweeping up from the horizon and meeting at a focal point nearly directly overhead. As the sky blazed, with the blue waves and crimson streamers, she heard: ". .. a distant tinkling, like bells. It came again, louder, just as a curtain of green light swept the entire width of the sky from north to south. Each time green flushed the sky, the bells rang, the sound softening to a gentle tinkle as the light died." (Hasselstrom, Linda; "Night of the Bells," Readers Digest , p. 185, April 1992. Cr. J.B . Dotson.) Comment. Note the correlation of the sound with the green portion of the aurora. July 29, 1990. On Coll Island in Centennial Lake, 120 kilometers west of Ottawa. Watching an auroral display, L.R . Morris heard the sound of the aurora: "It was a faint but distant windlike sound; which, by process of elimination, could not be accounted for by any phenomenon other than the aurora." (Anonymous; "Auroral Sounds," Sky & Telescope , 83:105, January 1992. Cr. D. Snowhook.) Comment. Auroras have been heard for centuries, but they "shouldn ...

... Indian Ocean. Aboard the s.s . Lima , Juaymah to Rotterdam. Third officer, S.M .F . Masud, and others of the ship's company observed another instance of one of the sea's great unex plained phenomena. "At 1800 UTC on a clear moonless night while 150 n.mile east of the Somalian coast a whitish glow was observed on the horizon and, after 15 minutes of steaming, the ship was completely surrounded by a sea of milky-white colour with a fairly uniform luminescence. The bioluminescence appeared to cover the entire sea area, from horizon to horizon but above the surface, and it appeared as though the ship was sailing over a field of snow or gliding over the clouds. "There was no damping effect on capillary waves or reduction of visibility at all and there was no mist at deck level although at a distance it seemed as if there was either lowlying mist or the upwelling of the luminescence itself. The bow waves and the wake appeared blackish in colour and thick black patches of oil were passing by. Later, the Aldis lamp revealed that the 'oil patches' were actually light-green kelp, amazingly black against the white water." A water sample contained many singlecelled microorganisms, but they displayed no luminescence. After 6 hours, the luminescence disappeared. Commenting on this report, P.J . Herring, of the Southhampton Oceanography Centre, said that milky seas are most often associated with the Southwest Monsoon. This one was was rare in that the Northeast Monsoon prevailed. His final remark ...
