In May 1987 a British submarine carried out an ice profiling experiment in the Arctic Ocean in which the route closely approximated that of an earlier voyage in October 1976. Over a zone extending more than 400 km to the north of Greenland there is evidence of a significant decrease in mean ice thickness in 1987 relative to that found in 1976. This thinning amounts to a loss of volume of at least 15% over an area of 300,000 km2 ." (Wadhams, Peter; "Evidence for Thinning of the Arctic Ice Cover North of Greenland," Nature, 345:795, 1990.) In an accompanying discussion of the ice problem, A.S . McLaren et al note that since the late 1800s, Arctic researchers using drills have reported consistently that the Arctic ice thickness averaged 3-4 meters. U.S . subma-rine surveys concurred with these figures during cruises in 1960 and 1962. Satellite surveys of ice cover from 19781987 found no trends. In other words, other sources of data on the Arctic ice reveal little change. The new results, therefore, need further confirmation. (McLaren, A.S ., et al; "Could Arctic Ice Be Thinning?"

Customarily, life is considered confined to a thin spherical shell of air, water, and earth. But the bits of drillers have demonstrated that life prevails as far down as we can pierce the planet's integument. Now, K.G . Stetter et al: ". .. report the discovery of high concentrations of hyperthermophiles [viz., bacteria] in the production fluids from four oil reservoirs about 3,000 metres below the bed of the North Sea and below the permafrost surface of the North Slope of Alaska. Enrichment cultures of sulphidogens grew at 85 C and 102 C, which are similar to in reservoir temperatures." Stetter et al favor the theory that these hyperthermophiles were injected into the reservoirs through: (1 ) drilling and secondary-recovery operations; and/ or (2 ) natural penetration via faults and seeps. They pointedly distance themselves from the idea, championed by T. Gold, that subterranean bacteria are actually permanent ancient residents of a deep subterranean biosphere.

The usual explanation is that the layers of older rocks were thrust parallel to the bedding planes over the top of the layers of younger rock, sometimes for hundreds of miles. So numerous are these instances of inverted strata that a new branch of geology called Thin-Skinned Tectonics is arising to handle them. The present article deals with the complex stratigraphy in the Western Arbuckle Mountains in southern Oklahoma. Here are located many examples of old-on-young rock as well as completely inverted stratigraphic members. Much at-tention is paid to the evidence of sliding between beds (breccia, small overfolds, etc.). Some excellent photos of these contact planes are presented. (Phillips, Eric H.; "Gravity Slide Thrusting and Folded Faults in Western Arbuckle Mountains and Vicinity, Southern Oklahoma," American Association of Petroleum Geologists, Bulletin, 67:1363, 1983.) Comment. Some extensive thrust faults do not show as much evidence of horizontal sliding as those in the Western Arbuckles.

The grooves occur near the cementoenamel junction, mostly on molars and premolars, and usually on males. The diameter of the channel between adjacent teeth varies from 1-4 millimeters. (See SF#61 for an earlier item on the subject.) Proposed solutions to this riddle range from bacterial attack, to gritty saliva propelled through the teeth, to the overenthusiastic use of bone toothpicks. But Australian aborigines have provided a more convincing explanation. When the aborigines want, thin, strong cords for fashioning spears and spearthrowers, they take a pliable, thinned, kangaroo sinew, pull it down between their molars like dental floss and begin "stripping" it, by pulling it back and forth. They get their thin cords this way but also grooved teeth. (Eckhardt, Robert B.; 'The Solution for Teething Problems," Nature, 345: 578, 1990.) Comment.

It has added another layer of complexity that people are only now starting to consider in the context of whole ocean systems . . Gel is like the dark matter of the sea. While sea gel does not impede the snorkeler, . it does herd microbes into clumps or microniches . which we cannot see either.

A few statistics confirm the amazing complexity of the seawater microcosm and its incredibly high microbe population density.

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. So, polar ice is not physically impossible on Mercury, although it is defi nitely surprising so close to the sun. All that is needed is a little water in the planet's atmosphere. Mainstream thinking is that "passing comets and asteroids" might bequeath Mercury some of their H2O cargos. (Cowen, R.; "Icy Clues ...

The smaller ones are completely consumed. A few bigger ones reach earth and are renamed "meteorites." 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. But these effects are inadequate to explain all observations. R. Spalding, at Sandia National Laboratories, ventures that ions in the upper atmosphere are electrostatically attracted to meteors and create light when they collide with them. A. Ol'khovatov suggests that "plasma instabilities" may be involved.

Such features are not particularly rare in deep-sea-creatures, but we do have to briefly describe this grotesque fish to get a delightful anomaly. It seems that in a few recovered specimens, the thin tail is tied in several overhand knots! Now moray eels can knot themselves, but the gulper eel is just a floating stomach with negligible musculature in its whiplike tail. So, just how did the knots get there?

... photographed in the infrared portion of the spectrum, luminous wave-like structures appear in the upper atmosphere. The wave crests are about 50 kilometers apart; lengthwise, they stretch up to 1.000 kilometers; altitude, about 85 kilometers. As many as ten waves may be seen at the same time. Morphologically, these waves resemble noctilucent clouds, which are sun-illumined, high-altitude clouds. The infrared waves, however, appear when the sun is well below the horizon. Since these waves are seen only at low angles over the horizon, some geophysicists propose they are the result of a geometric effect produced by viewing a rippled layer of weakly emitting gases in the upper atmosphere. When one looks at this rippled layer just above the horizon, one sees alternating thick and thin sections due to the perspective. The thick portions will appear brighter than the thin sections. As for the origin of this postulated rippled layer; no one is sure. Gravity waves may be involved. (Herse, M.; "Waves in the OH Emissive Layer," Science, 225:172, 1984.) Comment.

This time, the anomalies are associated with three bright rings now gracing 1987A's environs. The thin, dense, elliptical inner ring, the first to be noted, has always been a puzzle. Its diameter suggests that it was probably created about 30,000 years before 1987A blew up. But what is it? Its existence is hard to explain, as N. Panagia has confirmed: "The presence of a dense, thin, ring surrounding a massive star at the end of its evolution is not easy to account for." In other words, this ring is foreign to mainstream astronomical theory. Now, with the help of the Hubble Space Telescope, two additional faint rings near 1987A have been detected. One seems to be the mirror image of the other. The bizarre part is that they are not centered on 1987A at all, like the ring mentioned above. One of the new rings seems to be in front of 1987A, the other in back -- but this is a subjective call. Speculation is rampant, and all three rings are enigmatic.

We like to think this way because we so much want to find life on our sister planet, and to us water is life! Not so fast! says N. Hoffman from La Trobe University in Victoria, Australia. According to his hypothesis, water has had little or no importance in shaping the Martian landscape. Instead, his 'White Mars' model contends that the gurgling, frothing and sometimes explosive venting of carbon dioxide gas from beneath the surface created the features. Outrageous as Hoffman's hypothesis is, it is supported by several significant observations that seem to deny a watery Mars. The Mars Global Surveyor has not detected any carbonate minerals that should have been created when water interacted chemically with the planet's CO2 atmosphere.

It is generally known that you can separate fresh eggs from hard-boiled eggs by spinning them like a top. If they are hard-boiled they will spin on one of the ends.

O.K .! this is not very curious, so we'll place a hard-boiled egg in a flat pan containing a thin layer of water and give it a spin. Not only does the egg spin on end but a layer of water creeps up the side of the egg. When the water is about half way up the side of the egg it breaks up into droplets and sprays out horizontally like a rotating lawn sprinkler. No mysterious forces are involved, nor are there spooky quantum mechanics effects. The major forces operating are gravity, centrifugal force, and adhesion between the egg surface and the water. As the film of water creeps up the egg, the centrifugal force increases and overcomes the force of adhesion. Then, water droplets spray outward.

The shadows were exactly the same shape as the remaining bright portion of the Sun, by then only a thin arc of light. Why?" This phenomenon is not anomalous but it is entertaining. It is the reverse of the pin-hole-camera effect often seen during total eclipses. People standing in the shadow of a tree will see many bright arcs on the ground -- images of the sun being eclipsed.

Molten material pushing out along these ridges spreads out, solidifies, and is magnetized by the prevailing terrestrial magnetic field. Thus, the spreading sea floor becomes a "tape Recorder" preserving the record of changing terrestrial polarity over the past several hundred million years. As one drills into this thin conveyor-belt/tape-recorder, one would expect to encounter only rocks of one polarity. Not so! Some of the holes drilled by the Deep Sea Drilling Project have passed through several polarity zones. To illustrate, core 395A from the mid-Atlantic ridge is magnetized normally for the upper 170 meters, reversely for the next 310 meters, and normally again for 40 meters.

We mentioned this conundrum briefly in SF#125. We now have the scientific details at hand concerning the supporting observations made during the November 1998 Leonid bombardment. The observations were made by an international team in China. Photographic cameras were employed as well as an all-sky TV camera equipped with an image intensifier. All photographed meteors began to visibly burn up below 130 kilometers, but the TV camera consistently picked up the same meteors at higher altitudes. Both sets of cameras recorded the same final burn-up heights. The most startling observation was a meteor that the TV camera detected at roughly 200 kilometers altitude. The highest observed Leonid meteor with initial mass of about 1 kg started radiating at an altitude of almost 200 km.

The Maine Coast. An expedition from Harvard and the American Academy of Arts and Sciences, led by Samuel Williams, had set up equipment to observe the predicted total eclipse of the sun. A solar eclipse occurred all right, but the expedition was shocked to find itself outside the path of totality. They saw a thin arc of the sun instead of its complete obscuration by the moon. Modern analyses of this embarrassing incident for embryonic American science blame Williams for miscalculating the path of totality. Actually, recent computations compound the mystery. The expedition measured the time of the eclipse as 40 seconds later than it should have been for their (erroneously selected) site. Modern analysts insist further that the expedition should have seen an arc 10 arcsec wide subtending an angle of 89 ; instead, Williams and his colleagues measured an arc of less than 24 .

The satellite, called Lageos, is covered with laser reflectors so that it can be tracked with high precision. At its altitude of 3700 miles, the earth's atmosphere is supposed to be so thin that friction will bring the satellite only 1/250th of an inch closer to the earth each day. The trouble is that Lageos actually falls at ten times this rate. In 1979 it descended 60% faster than it does now. Lageos will stay in orbit several hundred thou-sand years, but space scientists are understandably concerned about their theories about the upper atmosphere. Many suggestions have been made to explain this anomaly. Some say the atmosphere is thicker than expected; others prefer to think there is more helium than predicted; but the "plasma drag" effect seems to fit the situation the best. Lageos may, in fact, be electrically charged and interacting with the surrounding cloud of electrically charged particles and is ever so slightly braked by the electrical forces.

One well-observed ice ring appeared in the Pite River in northern Sweden in 1987, About 100 feet in diameter, it was rotating slowly within a slightly larger hole in the ice covering the rest of the river. (SF#112) This ring was fashioned out of ice floes that had been captured by a whirlpool and set spinning. Its rough periphery had been "machined" to circular perfection over a period of weeks as it rotated ponderously within the confining river ice. A curious phenomenon is this, but one that seems to yield to simple explanation rather easily. Somewhat more puzzling is a 16-foot ice ring that formed overnight in the more placid waters of a farm pond near Delta, Ontario, in December 2000. The ice was too thin to walk upon, so it had to be a natural phenomenon. However, there was no whirlpool to provide the lathe-like action needed to create the neat disc.

The popular press quickly announced that the Martians were signalling us. Actually, this assumption was quite understandable because in those days the newly discovered Martian "canals" were in everyone's thoughts. Most scientists, however, rejected the signal notion preferring to attibute the flare to the specular reflection of sunlight from snowy peaks on Mars. But they were wrong, too. Close-up inspection by modern spacecraft has revealed no snowy peaks or large bodies of water on Mars that might mirror the sun. But another possibility has now come to the fore. The Martian flares could be reflections of sunlight from flat, hexagonal crystals of water ice in the thin Martian clouds; the same crystals that create some of the solar halos and sun dogs seen on earth. That this sort of specular reflection does occur was demonstrated on June 7, 2001, when a flare was actually photographed in the area of Edom Promontorium. The photography was possible because scientists had been watching this spot intently -- with cameras at the ready -- because a well-observed flare had occurred at this location in 1954, and calculations showed that conditions would be just right for the sun to be again reflected by clouds at this spot on June 7, 2001.

The bubble ascended slowly, higher and higher, and developed into a huge semicircular cupola or dome before halting for a few minutes.

By then, the cupola almost completely covered the Big Dipper (Ursa Major) whose five or six brighter stars clearly sent their rays through the phenomenon. The cupola had sharply-cut edges all round it, until later when a thin arm-like feature separated from its right topside and bent in the direction of the cupola, while remaining slightly apart from it.

In fact, to a crystallographer, these crystals are the equivalent to ESP in psychology. All the rules of crystallography insist that icosahedral crystals should not exist. One scientist reacted in this way: "All my training has been with the assumption that crystals are periodic. Now, almost everything has to be reexamined." Actually, the icosahedral crystals are "quasi-periodic"; that is, they are completely regular only over small distances.

A key marker of this boundary is a thin "spike" of iridium that is found worldwide, and which was supposedly deposited by the asteroid impact that helped finish off the dinosaurs. For many scientists, the asteroid-impact scenario has become a "non-negotiable" brick in the Temple of Science. The problem they have faced is that the iridium layer is variable in thickness and concentration from site to site. Sometimes iridium can be detected well above and below the K-T boundary. This variability has tended to undermine the asteroid-impact theory. Recent experiments at Wheaton College by B.D . Dyer et al have demonstrated that bacteria in ground water can both concentrate and disperse iridium deposits. In other words, bacteria could smear out an iridium spike, perhaps partially erase it, or even move it to a deeper or shallower layer of sediment.

To make bark paper, one first takes the inner layer of bark, or bast, from a tree. This material is then thinned, widened, and made flexible by soaking it in water and beating it. The final product retains much of the bark's structure with its interconnecting fibers. Ordinary paper today is also made of wood fibers, but the original fiber interconnections are destroyed in the pulping process. The manufacture of bark paper requires characteristic grooved beaters, specimens of which have been found in both Mesoamerica and Southeast Asia. Were bark paper and the tools required to make it invented independently on both sides of the Pacific, or were they transported across the Pacific by early navigators?

Captured enemies helped solve the protein problem, but pigeons were much more common, and some species were good-sized and delicious.

The evening of July 23 was warm and a bit humid, with a modest breeze blowing in from the ocean. Netley and wife first saw the "cloud object" from a distance of about a kilometer; they eventually walked to within 400 meters of the phenomenon. The "object" consisted of a slowly rotating ring of thin, vertically oriented clouds. (See figure.) The cloud ring was 80-100 meters across and seemed to rotate in a horizontal plane at the rate of about one revolution per minute. As though this were not strange enough, the rotating "cloud object" itself moved in a larger circle 8-10 times the diameter of the "cloud object." The "cloud object" took 4-5 minutes to complete a trip around the larger circle. The phenomenon lasted for about an hour before dissipating. (Netley, Edward; "Unusual Circulating Cloud Object," Journal of Meteorology, U.K ., 21:384, 1996.) Sketch of the revolving "cloud object". Part of the circle is omitted for clarity; it was actually complete ...

... 1986. He was duly pilloried for his trouble. But, at the 1997 spring meeting of the American Geophysical Union, Frank presented new data to back up his previous assertions. The most startling of his new evidence came from a camera aboard a NASA satellite. Time-lapse photos imaged two objects streaking into the atmosphere over Poland and Germany. Frank identified these as clouds of water molecules from disrupted icy minicomets. The clouds had expanded from the house-size minicomets to clouds 3550 miles wide, weighing 20-40 tons. Frank thinks the minicomets come from a cloud of such objects orbiting the sun from earth out to Jupiter and beyond. Why don't they evaporate in the sunlight and near-vacuum of outer space? Perhaps, thought Frank, they are protected by a thin coating of carbon. (Roylance, Frank D.; "Space Snowballs Theory Gains Credence," Baltimore Sun, May 29, 1997. Also: Monastersky, R.; "Is Earth Pelted by Space Snowballs?" Science News, 151:332, 1997. Thanks to all who sent in clippings. There are too many to mention here. Frank's photos also appeared on some national news programs.) Comments. We have already mentioned the minicomets several times in SF. See SF#60/275, for example. If verified, icy minicomets might well be the source of some of the earth's ocean water. Perhaps they are related to those strange "nebulous" meteors (SF#86/75) and noctilucent clouds.

Science Frontiers ONLINE No. 34: Jul-Aug 1984 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects The Carbon Problem The "carbon problem" seems to hit the scientific creationists the hardest, but it also has interesting implications for today's earth. Consider first where the carbon in the earth's crust resides: Petroleum 201 x 1018 grams Coal 15 Limestone 64200 Biosphere 0.3 In this article, these figures are made more understandable by physical descriptions of some of the truly colossal deposits of oil, coal, and limestone. For example, in the Canadian Rockies, the Livingstone limestone was deposited 2000 feet deep on the margin of the Cordilleran geosyncline but thins eastward to about 1000 feet in the Front ranges. ". .. it may be calculated to represent at least 10,000 cubic miles of broken crinoid plates." Two implications are: Even if the earth's biosphere were completely converted into oil, coal, and limestone each year, the earth would have to be far older than the 6000 years desired by the creationists, unless most of the carbon deposits had non-biological origins, which seems unlikely. The immense inventory of carbon tied up in biologically produced deposits was originally abiogenic. Where did it come from? Abiogenic methane and carbon dioxide released from the crust seem the most likely sources. This means that the crust must have once had, and may still have, prodigious supplies of methane. T. Gold and S. Soter have long argued that the earth's crust still ...

The reference did not specify the Martian hemisphere, but it was probably the northern, where there are extensive lowlands. In fact, if water once did flow on Mars, 75% of it would have drained into these lowlands. (Anonymous; "Mars in 3-D ," Science News, 156:11, 1999.) Back in 1976, the Viking Orbiter sent back pictures of so-called "searchlight areas" in the northern hemisphere. The speculation then was that these glassy, seemingly transparent features might be thin layers of ice.

The cylindrical microfossils average 50 x 110 microns and are the size and shape of fecal pellets produced by microscopic animals today. Pellets occur in dark gray and black rocks that were deposited in the facies that also preserves sulfide minerals and that represent environments analogous to those that preserve fecal pellets today. Rocks containing pellets and algal microfossils range in age from 0.53 to 1.9 gigayears (Gyr) and include Burgess Shale, Greyson and Newland Formations, Rove Formation, and Gunflint Iron-Formation. Similar rock types of Archaean age, ranging from 2.68 to 3.8 Gyr, were barren of pellets. If the Proterozoic microfossils are fossilized fecal pellets, they provide evidence of metazoan life and a complex food chain at 1.9 Gyr ago. This occurrence predates macroscopic metazoan body fossils in the Ediacaran System at 0.67 Gyr, animal trace fossils from 0.9 to 1.3 Gyr, and fossils of unicellular eukaryotic plankton at 1.4 Gyr."

... for panspermia to work at interstellar distances. However, if the spores are transported in dark, molecular clouds, which are not uncommon between the stars, survival times of tens or hundreds of million years are indicated by the experiments. Under such conditions, the interstellar transportation of life is possible. But perhaps the injection and capture phases of panspermia might be lethal to spores. Weber and Greenberg think not -- under certain conditions. The collision of a large comet or meteorite could inject spores from a life-endowed planet into space safely, particularly if the impacting object glanced off into space pulling ejecta after it. The terminal phase, the capture of spores from a passing molecular cloud by the solar system and then the earth, would be nonlethal if the spores were somehow coated with a thin veneer of ultraviolet absorbing material. In sum, the experiments place limits on panspermia, but do not rule it out by any means. (Weber, Peter, and Greenberg, J. Mayo; "Can Spores Survive in Interstellar Space?" Nature, 316:403, 1985.) Comment. Weber and Greenberg do not discuss the possible existence of dense, low-temperature regions in molecular clouds where conditions might be conducive to the development of large molecules.
