The magnetic direction toward which nudibrachs spontaneously oriented in the geomagnetic field showed recurring patterns of variation correlated with lunar phase, suggesting that the behavioral response to magnetism is modulated by circa-lunar rhythm." The magnetic and lunar-phase detectors of this mollusc are not known. In fact, the authors remark in their introductory paragraph that, even in organisms possessing ferromagnetic materials in their systems, there exists no "direct neurophysiological evidence implicating ferromagntic particles in the the detection of magnetic fields."

The focus of a 1987 paper in Scientific American, by C.H . Nelson and K.R . Johnson, is the northeastern Bering Sea, where sensitive side-scanning sonar has sketched large numbers of pits and furrows in the shallow sands. The pits range from 1-10 meters in length, 0.5 -7 meters in width, and 0.1 -0 .4 meters in depth. No known geological processes seem responsible. Farther east, in Nor-ton Sound, methane eruptions from buried organic matter do blow out circular craters; but the elongated pits investigated by Nelson and Johnson are gouged in sand considered too permeable for gas-crater formation. Rather surprisingly, the gray whale has become suspect as a pit excavator. They feed in the area of the pits; and the pits, before enlargement by currents, are just the size of the whales' mouths. The whales apparently dredge up sediment and, with their baleen, strain out amphipods (shrimp-like crustaceans) from the sand. The coexisting narrow furrows turn out to be the work of walruses digging for clams. (Nelson, C.

We have looked at 5,927,978 French births occurring between the months of January 1968 and the 31st December 1974. Using Fourier's spectral analysis we have been able to show that there are two different rhythms in birth frequencies: (1 ) A weekly rhythm characterized by the lowest number of births on a Sunday and the largest number on a Tuesday; (2 ) An annual rhythm with the maximum number of births in May and the minimum in September-October.

The clear favorite among the four contending hypotheses was the earth-impact scenario, which may be stated as follows: "Near the end of the Earth's accretion, after its core had formed and while the growing planet was still molten, an object at least the size of Mars smashed into it at an oblique angle. The cataclysm put large quantities of vaporized or partially vaporized impactor and Earth into orbit. The primitive Moon formed from that material." Conferees turned thumbs down on the theory that the moon was captured by the earth. Still not ruled out are the double-planet hypothesis (earth and moon accreted in their present configuration) and the fission-from-earth theory. (Taylor, G.

Oil and gas should not be down there in any quantities according to current theory, but that's what they are drilling for. Isn't it futile to fight such a well-established dogma that oil and gas have biological origins and therefore must be looked for only where life once thrived? Not any longer! Enough anomalies have accumulated to seriously challenge the idea that oil and gas are byproducts of ancient animal life. Here are a few of these anomalies: The geographical distribution of oil seems derived from features much larger in scale than individual sedimentary features. The quantities of oil and gas available are hundreds of times those estimated on the basis of biological origins. The so-called "molecular fossils" found in oil and claimed as proof of a biogenic origin are simply biological contaminants, particularly bacteria that feed upon the petroleum. Petroleum is largely saturated with hydrogen, whereas buried biological matter should exhibit a deficiency of hydrogen. Oil and gas are often rich in helium, an inert gas which biological pro cesses cannot concentrate. The great oil reservoirs of the Middle East are in diverse geological provinces.

Early the next morning, people in a van driving past the lake discovered the body of a motorcyclist. The air smelled like battery fluid. One of the van's occupants collapsed. The others ran for their lives toward Njindom. By 10:30 AM authorities had found 37 bodies along a 200meter stretch of road by the lake. Blood was oozing from the noses and mouths; the bodies were rigid; first-degree chemical burns were present. Also, animals and plants along the shore had been killed. 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.

On Earth, salt diapirism leads to the formation of salt domes, anticlines, and elongated salt intrusions -- features which have dimensions of roughly 1 to 100 km. Due to the rapid erosion of salt by water, surface evaporite landforms are only common in dry regions such as the Zagros Mountains of Iran, where salt plugs and glaciers exist. Venus is far drier than Iran; extruded salt should be preserved, although the high surface temperature (470 C) would probably stimulate rapid salt flow. Venus possesses a variety of circular landforms, ten to hundreds of kilometers wide, which could be either megasalt domes or salt intrusions colonizing impact craters. Additionally, arcuate bands seen in the Maxwell area of Venus could be salt intrusions formed in a region of tectonic stress.

Muller and D.E . Morris review the evidence tying geomagnetic reversals to the impacts of large bodies with the earth: the tektites and microtektites; the climate changes; the biological extinctions, etc. Then they propose a physical mechanism for geomagnetic reversals: "The impact of a large extraterrestrial object on the Earth can produce a geomagnetic reversal through the following mechanism: dust from the impact crater and soot from fires trigger a climate change and the beginning of a little ice age. The redistribution of water near the equator to ice at high latitudes alters the rotation rate of the crust and mantle of the Earth. If the sea-level change is sufficiently large ( 10 meters) and rapid (in a few hundred years), then the velocity shear in the liquid core disrupts the convective cells that drive the dynamo. The new convective cells that subsequently form distort and tangle the previous field, reducing the dipole component near to zero while increasing the energy in multipole components. Eventually a dipole is rebuilt by dynamo action, and the event is seen either as a geomagnetic reversal or as an excursion."

Now, we have a long list of craters or astroblemes (star wounds), some of which measure hundreds of miles across. In fact, there are enough large dated crters so that some scientists have taken up a time-honored human pastime: Looking for cycles or periodicities in the data. (Humans can find cyclicities in almost any collection of data!) To be more specific, some have claimed that large meteor craters come in clusters dated 28-31 million years apart. These catastrophic events have been correlated with biological extinctions, magnetic field reversals, and basalt flooding. The astronomical causes of this supposed periodicity range from the solar-system's crossing of the galactic plane, to the perturbations of an unseen solar companion, to regular perturbations of the Oort cloud of comets that is thought to hover at the fringe of the solar system.

After some computations Melosh concludes: "It seems likely that the impacts that produced craters on Earth that are greater than 100 km in diameter would each have ejected millions of tons of near-surface rocks carrying viable microorganisms into interplanetary space, much in the form of boulders large enough to shield those organisms from ultraviolet radiation, low-energy cosmic rays, and even galactic cosmic rays. Under such circumstances spores might remain viable for long periods of time." (Melosh, H.J .; "The Rocky Road to Panspermia," Nature, 332:687, 1988.) Comment.

This allowed him to calculate the mass influx for the earth during this period. His conclusion: if only about 10% of the incoming mass consisted of comets (mostly ice), the earth would have acquired all its ocean water.

Pearson. He ventures that our ponderous moon (much larger than the moons of Mars) was the key to the melting of the earth's core via tidal friction. With a fluid core, the earth developed a strong magnetic field (much stronger than those of the other inner planets) through dynamo action. This field protected nascent life from space radiation -- and here we are! (Hecht, Jeff; "Lunar Link with Life on Planets," New Scientist, p. 40, January 21, 1988.) Comment.

Cyclothems may also be useful. Cyclothems are groups or bundles of strata that repeat themselves in stratigraphic columns. A generalized cyclothem from Illinois is shown in the illustration. In the U.S . western interior, rhythmic sedimentation appears in the Fort Hays Limestone Member of the Niobrara Formation. These cyclothems can be correlated over distances exceeding 800 kilometers and are believed to be the consequence of climatic changes associated with the earth's precession and orbital eccentriciy. These rhythms have been captured in bundles of shale-limestone couplets. A bundle of five coup lets, for example, is thought to express 21,000- and 100,000-year Milankovitchtype climatic cycles, as impressed by variations in the earth's orbital precession and eccentricity.

Now, if scientists could show that all of these phenomena occur at the same frequency and are roughly in phase, it would constitute one of science's most important syntheses. The stratigraphic record and the estimated ages of meteor craters certainly hint at such synchrony. Recently, two more papers have appeared which support the above scenario. First, M.R . Rampino and R.B . Stothers show that during the past 250 million years, eleven episodes of basalt flooding have occurred with an average cycle time of 32 million years. Second, J.

Calculations, too, support the notion that a large meteoric impact could propel bits of the Martian surface into space where, statistically speaking, a tiny fraction would be captured by the earth's gravitational field. Some of these would fall to earth; others would remain in orbit. Now, the reverse scenario has been investigated numerically. S.A . Phinney and colleagues at the University of Arizona have calculated what would happen to small chunks of the earth's crust if a large meteor impact excavated a 60milewide crater. "Phinney's group used a computer to calculate where 1,000 particles would go if ejected from Earth in random directions, moving about 2.5 kilometers per second faster than the minimum speed necessary to escape. Of the 1,000 hypothetical particles, 291 hit Venus and 165 returned to Earth; 20 went to Mercury, 17 to Mars, 14 to Jupiter and 1 to Saturn.

Instead, the ages seem to cluster at 7 and 30 million years." Astronomers have hitherto been content to attribute these clumped ages to collisions among the meteorites' parent bodies - the asteroids - which ply periodic orbits. However, S. Perlmutter and R.A . Muller, at Berkeley, point to the apparent 26- to 30-million-year periodicities of three terrestrial phenomena: Biological extinctions in the fossil record, Magnetic field reversals, and Terrestrial-crater ages. Could there be a connection between the clumped meteorite ages and these terrestrial phenomena? Perlmutter and Muller propose that all of these phenomena are the consequence of periodic storms of comets that invade the inner solar system from the direction of the Oort Cloud of comets that purportedly hovers at the fringe of the solar system. These comets not only devastate the earth but also collide with the asteroids, knocking off those bits and pieces we call meteorites. (Anonymous; "Do Meteorite Ages Tell of Comet Storms?"

Currently, he is promoting the theory that many of the earth's hydrocarbon deposits (gas, oil, graphite, etc.) are not of biological origin but are formed rather when primordial methane outgases from the planet's interior. A vanishingly small number of geologists buy Gold's theory. Nevertheless, the Swedish State Power Authority and some private investors have been impressed enough to fund a drilling project at the Siljan Ring, a meteorite crater 150 miles north of Stockholm. There are no significant sources of biogenic hydrocarbons nearby, but oil seeps are not uncommon around the Ring. Mainstream theory cannot account for these seeps, but Gold's theory can: primordial methane streaming up through the cracked granite shield is converted, probably with the help of bacteria, into oil and hydrocarbon sludge. "Ridicuous," say the mainstreamers. Recently, the drilling program, which has reached the 22,000foot level, brought up 60 kilograms of very smelly black sludge with the consistency of modeling clay. The gunk seems to have a biological origin. In addition to the black sludge, the drillers have been encountering increasing quantities of various hydrocarbon gases as the hole went deeper.

What a turnabout in scientific thinking in just a decade. F.T . Kyte et al have now provided additional details on meteoritic debris they first described in 1981. On the floor of the southeast Pacific, about 1400 kilometers west of Cape Horn, about 5 kilometers down, they found high concentrations of iridium in Upper Pliocene sediments about 2.3 million years old. Since the proposed projectile hit in very deep water, no crater was dug out. What did survive is called an "impact melt." This is debris rich in noble metals, such as iridium, and contains particles typical of a low-metal mesosiderite. Some 600 kilometers of the ocean floor received this debris. Kyte and his associates estimate the size of the impacting object at at least 0.5 kilometers in diameter. No biological extinctions are correlated with the 2.3 -million-year date, but there appears to have been a major deterioration of climate at about this time. There was a shift in the marine oxygen isotope records and, more obvious, the creation of the huge loess (sandy) deposits in China.

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?"

These magnetic concentrations (called "magcons") are located precisely on the opposite side of the moon from the larger lunar basins. How could an impact on the moon magnetize the antipodal region? The impact of a large silicate meteoroid at speeds of 10 kilometers/second would not only blast out a big crater but it would also create a huge cloud of hot, partially ionized gas. This hot gas or plasma will conduct electricity and interact with lunar magnetic fields. As the plasma cloud spreads away from the ... site, it acts like a bulldozer, compressing the lunar magnetic fields ahead of it, as it envelopes the whole moon and rushes towards the antipodal point.

These are the layered or Muong-Nong tektites, which are not aerodynamically sculptured. They come instead in large, irregular masses, 3-20 centimeters thick, weighing up to 24 kilograms. Their layered appearance is thought to result from flow and stirrings as they solidified in small pools of melted rock and soil splashed from nearby impact craters. These irregular chunks of solidified melt could not have traveled great distances like their streamlined brothers. They lie at most only a few crater diameters from their parent craters. Since layered tektites are found over an area 800 x 1140 kilometers in extent, and they are not far-travelers, Southeast Asia must have been peppered with many small cosmic projectiles 700,000 years ago (the disputed age of the event).

The lozenge, of 0.5 -mm beaten gold, was excavated in 1808 AD from the Bush Barrow, 1 km from Stonehenge. "Until now, it has been assumed that the plaque was only decorative. After examination and measurement, the patterns of its carefully inscribed markings are believed to be identifiable as a calendar fashioned for use at Stonehenge. Found over the breast of a skeleton of a tall man, its symmetrical shape and correct corner angles make it appear probable that the plaque had something to do with the four cardinal points and solstitial sunrises and sunsets. Markings on a gold lozenge excavated near Stonehenge. Some interpret the lines as indicators of solar and lunar positions on astronomically significant days. If so, this lozenge represents surprising sophistication 3600 years ago. "By fixing the flat lozenge on a table at eye level and orientating it with its shorter diagonal on the meridain, an observer could use an alidade while watching sunrise or sunset throughout the year. Were the bronze rivets, found nearby, the remains of the alidade? Markings exist on the plaque which indicate that the 16-month calendar was in use. Guide lines exist for inserting the intercalary leap day. Eight additional lines can be identified as indicating moonrise and moonset at the equinoxes' standstills. Using actual horizon altitudes at Stonehenge and azimuths shown by the lozenge, calculation shows that the average discrepancy of the solar lines is 0.36 days and that it was made about 1600 ...

Helfer, University of Rochester, noting the absence of extensive cratering on the northern plains of Mars, suggests that some 2-3 .5 billion years ago these plains were covered with oceans. These ancient seas, perhaps as much as 700 meters deep, protected the plains from direct impacts. Further, crater density counts for Chryse and the Martian highlands imply that Mars possessed a fairly dense atmosphere until about 1.5 billion years ago. In his Abstract Helfer speculates as follows: "With both early Earth and early Mars having similar atmospheric compositions and not too dissimilar atmospheric structures, it is reasonable to suppose that the warm Martian oceans, like the ancient oceans of Earth, would develop anerobic and aerobic photosynthesizing prokaryotes and structures like stromatolites. Their development might have changed the Martian atmosphere. Their fossils might be found along the fringes of the old oceans, the northern lowland plains." (Helfer, H.L .; "Of Martian Atmospheres, Oceans, and Fossils," Icarus, 87:228, 1990.) Comment. The Gaia influence is seen in the molding of the Martian atmosphere into something more conducive to the development of life. One can also speculate that, if life did develop on Mars, it could have seeded the earth via bits of debris blasted off by meteorite impacts. Several meteorites picked up in Antarctica are thought to have come from Mars ...

... down." Thus have the Maoris sung. Their myths, songs, and poetry clearly link the demise of the moa, not to their own overhunting as others maintain, but rather to a cataclysmic event that occurred some 800 years ago. Maori oral history tells of "the falling of the skies, raging winds, upheaval of the Earth, and mysterious devastating fire from space." Even some of the place names in New Zealand relate to some kind of catastrophe. In the province of Otago, there is Waipahi (place of the exploding fire) and Tapanui (big explosion). Oral history is entertaining, but scientists want something more palpable before they will entertain Velikovskian ideas about recent history. Well, if you visit Tapanui (big explosion place), you can find Landslip Crater, a 900 x 600meter depression 130 meters deep. This does not have the appearance of a bona fide meteor crater, but all around it are suspicious signs. For example, treefall distribution from 800 years ago was radially away from Tapanui out to 4080 kilometers. In the same area one finds the trinities, small globules of silicates with tektite overtones. And then there is the extirpation of the moas about this time. To be sure, there are separate, conventional explanations of all these phenomena. But, if you add the Maori oral traditions to all these suspicious physical signs, a Tunguska-like event does not seem impossible.

Science Frontiers ONLINE No. 77: Sep-Oct 1991 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Mercury: the impossible planet Mercury, largely hidden in the sun's glare, also conceals beneath its baked, cratered surface: (1 ) far more iron than solar-system theory allows; and (perhaps) (2 ) a dynamo that should not exist. Let us take the excess-iron problem first. Mercury's density is 5.44 (compared to earth's 5.52), so that it very likely contains much iron. Our moon, which resembles Mercury in size and external appearance, only has a density of 3.34, implying an altogether different origin. In the currently accepted theory of solar-system formation, all of the planets and their satellites condensed from a primordial disk of dust sur rounding the just-formed sun. The planets closer to the solar inferno lost more of their easily vaporized constituents due to the sun's heat. The cooler, outer planets were able to retain large amounts of ices. In this scenario, we would expect Mercury to be rich in iron and rocks. This seems to be the case, but it has too iron to fit the theory. Astronomers have tried to save the theory by supposing that a large asteroid sideswiped Mercury tearing off part of its outer layer of lighter rocks, leaving the heavier iron core untouched. The theory doesn't say what happened to the debris from this colossal collision. As for Mercury ...

... April 5, 1991. Cr. Y. Matsumura via L. Farish) Speculations. Apparently, plasmoids can be of any size: crop circles may be 100 feet in diameter of just a foot or two, and now we may have centimeter-sized expressions of plasmoid activity in the unexpected locale of the subway tunnel! Building upon these observations, it is not unreasonable to ask whether plasmoids (including plasma vortices) may not exist on larger scales, say, astronomical and geological. We are drawn to those strange swirl markings on the moon. These loop-like patterns are 1050 kilometers in size and are associated with strong magnetic anomalies. (See ALE5 in The Moon and the Planets.) And right here on earth we have the devastation of the Tunguska Event sans a gaping crater. And how about the shallow Carolina Bays, some of which are associated with magnetic anomalies? Could such phenomena be the handiwork of plasmoids rather than meteorites or comets? Plasmoids could also be involved in such phenomena as ball lightning, the cookie-cutter holes, and even spontaneous human combustion! Reference.

... tektites solidified about 700,000 years ago. Yet, their geological age, as measured by the age of the terrestrial sediments in which they are found, is only a few thousand years. This great disparity in age engendered a confrontation between geologists and geophysicists. The latter insisted on their 700,000-year figure; the former said "maybe so" but the tektites are still found only in very young, superficial sediments. The point here is that time-of-solidification may not be the same as time-of-fall. At stake is the prevailing theory, now dogmatically proclaimed, that tektites are created when a large asteroid impacts the earth, ejecting molten droplets of rock which shower back to earth as solidified tektites. No one has ever found a suitably large crater ( 200 miles in diameter) assignable to the Australasian tektite strewn field. Nevertheless, the impact model prevails; and the young geological age of the tektites is dismissed as erroneous. A Soviet scientist, E.P . Izokh, has recently proposed a radically different scenario that would produce both the young and old dates. If a moon, or Jupiter, or some similar body, explosively ejected the glassy tektites, embedded in an icy cometary body some 700,000 years ago, the tektites could, after cruising through space for millenia, have fallen to earth recently and over a wide area. Thus, both geologists and geophysicists would be satisfied! (Sullivan, Walter; "New Answer Proposed for Tektites: A Comet," New York Times, November 28, 1989. ...
