The line was observed to be a wave. "It was about 10 minutes after the first sighting that the vessel passed over the wave, which was approximately 4 m [13 feet] high, and she heeled 5 to port while the autopilot deviated 3 off course.

Tsunamis travel at jet speed and are rarely visible on the deep ocean. Since the wave was solitary and four times the height of the gentle swells, it is unlikely that it was a chance combination of the swells. Most likely it was a surface manifestation of an internal wave that had been reflected from ...

So wrote R.W . Service, the poet of the Arctic realms, about the eerie voices of the auroras. The low-frequency sound of the aurora is barely detectable by human ears. It is "felt" more than heard, as Service expressed so eloquently. Some skeptics have maintained that these ethereal sounds do not really exist, but modern instruments confirm that pressure waves are definitely produced in the atmosphere as the auroras weave and dance in the sky. Most auroral sound is in the infrasound range, which begins at the lower limit of human hearing -- about 20 Hertz. Just enough sound energy seeps over the 20-Hz limit to be heard by sensitive human ears during periods of intense activity. Another natural infrasound, weak but continuous, is the "voice of the sea." These sound waves, called "microbaroms," have periods in the 5-7 second range (0 .20-0 .14 Hz), well below the range of human ears. Such low-frequency sounds travel great distances with little attenuation. It is thought, therefore, that the "voice of the sea" is an extended source -- perhaps the collective acoustical signature of all the storms from all the world's oceans. ...

... A Shaky Measuring Rod"So saith M. Burbidge, an astronomer at the University of California at San Diego. Her assertion echoes what Arp has been proclaiming for years. (AR#3 ); namely that some redshifts are not due to the Doppler effect and an expanding universe. Since redshift is the major cosmological yardstick, the whole fabric of modern cosmology would become unwoven if redshifts cannot be used to measure distances reliably. We bring this subject up once more because Burbidge claims that some newly discovered quasar pairs cast additional doubt on redshift distance measurements. For example, she, along with Arp and Y. Chu, point to the quasar pair flanking the galaxy named Arp 220 (one of Arp's earlier discoveries). Quasars are very energetic sources of visible light, radio waves, and X-rays. The problem with Arp-220's flanking quasars is that they have much greater redshifts than the galaxy that seems to be situated in between them and likely at the same distance. Is this just a chance association, and the quasars are really much farther away than the galaxy -- as suggested by their high redshifts? Most astronomers believe this must be the case, but Burbidge and, of course, Arp, doubt it. They point to 10 other galaxies nearby that are also straddled by quasar pairs with higher redshifts. All of these were discovered within the last four years. Are they all merely chance associations? Arp contends that these quasar pairs are actually great masses of matter that have been ejected in opposite directions by the galaxies they flank ...

Issues This Issue Sourcebook Project Sourcebook Subjects Sandslides: Desert Catastrophes Some of the most important fossil discoveries being made today come from the desolate Gobi Desert -- a most unlikely place for the sudden mass burial of agile animals. Furthermore, the fossils now coming to light in the Gobi sandstones are not only abundant but also preserved with great fidelity. For example, at Ukhaa Tolgod, paleontologists are excavating the planet's largest assemblage of fossil vertebrates from the end of the Cretaceous Period (71-75 million years ago). In 1993, about 1,000 fossils representing 20 species of mammals and reptiles were collected. Amazingly, these bones were not disarticulated, scattered about, or severely worn. It was obvious that the Ukhaa Tolgod animals had been very suddenly engulfed by a "tidal wave" of sand. It was a catastrophic event of some sort. But what kind of catastrophes occur on desolate, riverless deserts? Wind is always blowing sand about and dunes creep along in deserts, but healthy animals easily avoid burial. Of course, there are rare, sudden downpours even on the Gobi. But one would expect this rain to be quickly absorbed by the sand. Intrigued by the evidence of unexpected catastrophism in the Gobi, scientists from the American Museum of Natural History first took a look at Nebraska's strange Sand Hills. These Sand Hills stretch for thousands of square miles, reach heights of 400 feet, and are believed to be of aeolian origin during the Pleistocene.

So far, all of this is well-understood. But when meteors begin to burn up much above 100 kilometers, a problem arises. The air there is normally much too thin to cause incandescence and burn-up. Observational anomalies are abundant. Two Leonid fireballs were seen glowing at 160 kilometers by Japanese scientists. In 1998, a Dutch team in China detected bright Leonids at 200 kilometers! In addition, some Russian reentering space-craft began glowing well above 100 kilometers. ANAL is a solid phenomenon. Of course, the density of the upper atmosphere does increase somewhat when solar activity is high. Atmospheric gravity waves can also cause the atmosphere to bulge out.

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.

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.

It 'manifests itself', he observed, 'in the form of larger or smaller ripples or waves stretching across the wake, the one behind the other, arising sometimes as far foward as almost midships'. When caught in dead water, Nansen reported, Fram appeared to be held back, as if by some mysterious force, and she did not always answer the helm. In calm weather, with a light cargo, Fram was capable of 6 to 7 knots. When in dead water she was unable to make 1.5 knots.

A few years ago the answer to this question would have been a resounding "no" from the experts on both volcanism and impact cratering, the only geological processes known to eject solid material at substantial velocities. Observation, however, has once again confounded expectation." In the snowy wastes of Antarctica, scientists have picked up meteorites that almost certainly came from the moon and Mars. And near St. Gallen, Switzerland, there was discovered a 22-centimeter block of Malm limestone that was apparently ejected from the Ries impact crater, almost 200 kilometers away, about 15 million years ago. We know all of these rocks are impact debris because they contain shatter cones indicating a violent origin. Not only did these bits of debris confound expectations, but their shatter cones implied shock-wave pressures far too low to achieve lunar and Martian escape velocities, or even the velocity necessary to propel that chunk of Malm limestone 200 kilometers. Something was wrong somewhere. It has turned out that shock-wave theory had been misapplied. It is not the pressure that is important in ejecting bits of debris from around the impact site, but rather it is the pressure gradient. Anomaly extirpated!

Such is the accepted picture of the brain. Unquestionably the brain does rely in part upon the transmission of electrical signals for some of its operations, but it now appears that there is a complementary mode of communication that relies upon chemistry rather than electricity. While the fastest way to transmit signals in the brain seems to be along the neurons and across their points of contact, the synapses, other signals may travel -- a bit more slowly -- by what is termed "volume transmission." Volume transmission is like broadcasting radio waves in three dimensions, except that in the brain the radio waves are replaced by the diffusion of chemical signals. L.F . Agnati et al explain: ". .. our experiments have shown that neurons also release chemical signals into the extracellular space that are not necessarily detected by neighboring cells but by cells far away, in the same way hormones released by a gland into the bloodstream can have effects on cells far away.

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 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."

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.

The first enlists the "Life-Saver effect (or "sugar-cube effect"). When Life Savers, sugar cubes, or rocks are fractured, light may flash from their broken surfaces. R.R . 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 News, 136: 375, 1989.) The second explanation of lunar flashes blames them on earth satellites passing in front of the moon. Satellite surfaces can flash like a car's windshield in sunlight, thus simulating a lunar flash. It was just this mechanism that was used to explain the mysterious "flasher" in the constellation Perseus. (SF#53) The May 23, 1985, lunar flash, reported in SF#64, may have been a reflection from a large military weather satellite that was transiting the moon at the time of the flash, say R.R . Rast and P. Maley. ...

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.

(AP) - Physicist Ed Wagner says he has found evidence that trees talk to each other in a language he calls W-waves. "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." "Explaining the phenomenon, Wagner pointed to a blip on a strip chart recording of the electrical pulse. "It put out a tremendous cry of alarm," he said. "The adjacent trees put out smaller ones." .. .. . "People have known there was communication between trees for several years, but they've explained it by the chemicals trees produce," Wagner said. "But I think the real communication is much quicker and more dramatic than that," he said. "These trees know within a few seconds what is happening. This is an automatic response." "Wagner has measured the speed of W-waves at about 3 feet per second through the air. "They travel much too slowly for electrical waves," he said. "They seem to be an altogether different entity. That's what makes them so intriguing. They don't seem to be electromagnetic waves at all." (Anonymous; "Physicist Says Blip ...

"When these waves, called seismic waves travel east-west they take two seconds longer to reach a point on the other side than if they travel north-south. The measurements of velocity take the slightly wider girth of the Earth from east to west into account." D. Anderson, director of Cal Tech's seismological laboratory states, "all of the possible explanations of this phe nomenon are outrageous." The "least outrageous" explanation for the anomaly is that the earth's outer core is not a pure liquid, but more like a slurry of aligned solid particles.

... 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. "More than three centuries later Porter observed a very different behavior in far southwestern Indiana in which, from the ends of a long row of tall riverbank trees, synchronized flashes '. .. began moving toward each other, met at the middle, crossed and traveled to the ends, as when two pebbles are dropped simultaneously into the ends of a long narrow tank of water ...
