Neither article mentioned the work of the other! Both groups of scientists processed massive quantities of earthquake records to form "seismic images" of structures deep in the bowels of the earth. (The technique is called "seismic tomography.") Both groups have discerned huge slabs of crust that were once on the planet's surface but were subsequently thrust (" subducted") down under the continents. These slabs are now hundreds of kilometers below the surface, and they have dragged water along with them. In fact, their water inventories may rival today's surface oceans; they may even have been surface oceans themselves millions of years ago before they descended into the infernal regions. Only a few years ago, all geologists maintained that all water in subducted slabs was squeezed out of the rocks by immense pressure and later reappeared at the surface as volcanic steam. Deep ocean #1 . G. Nolet and A. Zielhuis, Princeton seismologists, report a huge reservoir of water about 900 kilometers under present-day Europe. Some 400-500 million years ago, there was an ocean in this locale. (Zimmer, Carl; "The Ocean Within," Discover, 15:20, October 1994.) Deep ocean #2 . H.

Once again, comets seem to be the culprits. C.F . Chyba has examined the lunar impact record and derived an estimate of the total mass of objects impacting the moon during the (hypothetical) period of heavy bombardment 3.8 to 4.5 billion years ago. 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. (Chyba, Christopher F.; "The Cometary Contribution to the Oceans of Primitive Earth," Nature, 330:632, 1987.) Comment. Frank claims that the earth today is continually bombarded by small icy comets, which down the eons may have kept the ocean basins full. So, we have two possible extraterrestrial sources of oceans -- both of a cometary nature. It was only yesterday that the idea of ice surviving in outer space was ridiculed; no one even dreamed that our oceans could be composed of space ice!

Frank, at the University of Iowa, had detected dark spots on satellite images of the earth's dayglow. Frank thought that the spots might be due to clouds of water vapor released as small, icy comets hit the atmosphere. P. Huyghe has recently written more about Frank's discovery, his theory, and its reception by the scientific community. "These comets are not occasional visitors, he [Frank] says, like the one that comes by every 76 years and -- lucky for us -- never actually drops in. No, these are very small, cometlike objects that enter our atmosphere at a rate of 20 per minute, he says. These comets, which he believes must contain about 100 tons of water apiece, vaporize on impact with the atmosphere and fall as rain or snow. Now that may seem like one sizeable cold shower, but on a yearly basis he says it's actually only a tiny fraction of the annual preciptation. Then again, over a span of 4.5 billion years, which is about how old the earth is, that's enough water, he says -- trumpets blaring -- to create the oceans." Naturally, such a theory is very disturbing because it runs counter to the widely accepted idea that the oceans were created by the ...

The best explanation conventional geology has come up with is that they were formed some 2.5 billion years ago by geological processes not in operation today. G. Harper, however, thinks that these Wyoming rocks look very much like some of the slices of ocean crust (terranes) that continental drift's conveyor belt has plastered against North America's west coast. The conveyor belt is, of course, the ocean floor that dives under the continent. The more he looked, the more Harper was convinced that there, in the middle of the continent, was a substantial chunk of ancient ocean crust. The implications: continental drift and terrane plastering have been in operation for billions of years: ". .. from their very beginnings continents have been built up from the bits and pieces of plate tectonics." Some other geologists concur and point to similar rocks in northern Canada and around the Great Lakes. (Kerr, Richard A.; "Plate Tectonics Is the Key to the Distant Past," Science, 234:670, 1986.)

Rather than retrace all the details, it is sufficient to say that the scientific community has been generally negative and often condemnatory about L. Frank's assertion and evidence that each year some 10 million icy comets, each averaging sixty compact cars in weight, strike the earth's atmosphere and, in the fullness of time, help fill the ocean basins. In his article Huyghe reviews the considerable evidence that has accumulated supporting Frank's claim: The water in Halley's comet had the same abundances of two key isotopes as the earth's oceans; The rocket detection of unexpected amounts of water vapor in the upper atmosphere; The microwave detection of unusual water-vapor events in the upper atmosphere; The Lyman-alpha detection of hydrogen concentrated near the earth; and The photographic detection of small, incoming objects with the characteristics of the debated icy comets.

P. Huyghe, coauthor with L. Frank of The Big Splash, responded to SF#125 with three recent articles. Two reply to major criticisms of the icy-comet theory; the third gives geological and geophysical reasons why there must have been icy comets or some other substantial influx of water and carbon to the earth's surface down the geological eons. No instrumental artifacts. The basis for the 1985 claim of L. Frank et al that small, icy comets continually bombard the earth's upper atmosphere came from photos taken far above the earth from the Dynamics Explorer 1. Large, transient "holes" appeared in the atmosphere. These were attributed to vapor clouds created by small, icy comets.

For decades the stock answer has been: from the condensation of vapors escaping from the planet's cooling crust; that is, "outgassing." The possibility that some terrestrial water might have ar rived from extraterrestrial sources after the earth's formation has been discounted. The major reason behind this neglect was the expectation that the erosive effects of large-scale impacts of water-carrying comets and asteroids would preclude any net accumulation of volatiles, and could even reduce any existing inventories of surface water. C.F . Chyba has recently reexamined this question of cometary water influx vs. impact-caused water losses using the latest estimates of comet/asteroid fluxes during the period between 4.5 and 3.5 billion years ago, when bombardment of the inner solar system was thought to be especially severe. Rather than the expected net loss, Chyba computes that the earth would really have gained more than 0.2 - 0.7 ocean masses in that billion-year period. Venus would have fared equally well, but Mars, more sensitive to impact erosion, would have accreted "only" a layer of water 10-100 meters deep over the whole planet! (This Martian water is now mostly below the surface supposedly.) (Chyba, Christopher F.; "Impact Delivery and Erosion of Planetary Oceans in the Early ...

The view from a satellite, thousands of miles up, is startling to say the least. Huge bulges hundreds of feet high and hundreds of miles in extent appear when satellite radar altimeter data are plotted. Equally large depressions in the ocean surface also show up -- none obvious to surface observers. This unexpected macrostructure of the ocean surface is shaped by variations in the strength of the earth's gravitational field and sea-bottom terrain. Wherever the gravitational field is stronger, it creates a depression on the fluid surface. German geophysicists, in fact, have drawn a global map of the ocean's large-scale topography, as measured from the European Space Agency's ERS-1 satellite. The surface of the world ocean departs wildly from a smooth sphere.

... Not only did the poor dinosaurs have to contend with an asteroid impact and a lurch of the poles, but also with the possible ignition of voluminous methane burps. 65-million years ago. This was the time of the well-publicized, but still hypothetical, asteroid impact. It is said to have wreaked havoc on our wounded planet and, especially, the dinosaurs. Volcanos spewed out vast lava fields and filled the air with greenhouse gases and dust. It was a bad time for many life forms. Actually, It may have been far worse than generally advertised. In addition to the volcanic activity and climate change, the shock of the asteroid impact could have been sufficient to destabilize the immense amounts of methane hydrate that have long been locked up, frozen and dormant, in oceanic sediments all over the world. According to this scenario, once the shock of the asteroid impact released the methane from its icy prison, it rose to the surface of the oceans in a world-wide burp. Methane, unfortunately for the dinosaurs and many other life forms, is highly flammable. Lightning could have ignited it almost immediately if it was concentrated enough. A colossal firestorm might have then enveloped the entire planet. The whole atmosphere could have been afire. This, according to B. Hurdle and colleagues at the Naval Research Laboratory, who speculate that the dinosaur hegemony may ended suddenly in flames rather than in a long, drawn-out whimper.

Even though Lake Baikal is only 20-25 million years old, more than 5 kilometers of sediment have accumulated in some spots. These facts are remarkable as fresh-water lakes go, but Baikal also has features usually found only in salty oceans. It seals sport in fresh water 1,000 kilometers from the nearest salt water. (How did they get there?) Even more interesting are Baikal's thermal vents or chimneys that are otherwise restricted to cracks in the earth's crust in the deep oceans.

If you wish, you can accelerate the substance's demise by touching a match to it; it is packed with potential energy. The substance is methane hydrate, and it is found in prodigious quantities in oceanic sediments. Each cubic centimeter of methane hydrate contains about 160 cubic centimeters of methane at standard conditions; it is a concentrated source of natural gas. In fact, methane hydrate deposits in the world's oceans hold twice as much carbon as all the coal, oil, and gas reserves on land! But methane hydrate may be much more than a future fuel source; it may have been humanity's savior in eons gone by; it may be our future nemesis. You see, methane hydrate is very unstable; changes of temperature or pressure on a global basis can trigger the release of immense volumes of this greenhouse gas from oceanic deposits. For example, when the Ice Ages lowered ocean levels by locking up water in the advancing ice caps, pressures on ocean-bottom methane hydrate lessened and, according to some speculators, released enough gas so that the increased greenhouse heating turned back the Ice Ages.

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.

They have calculated that the oceans are leaking water into the Earth's mantle five times as fast as it is being replenished. It is true that ocean water is being drained away at subduction zones where oceanic crustal plates dive under the continental plates; there's a 10,000-mile unsealed crack there. S. Maruyama and colleagues at the Tokyo Institute of Technology estimate that 1.12 billion metric tons of water leak through that crack in the earth's integument every year. Geologists have always assumed that most of this leakage was returned to the oceans through deep-sea vents and volcanic action, but Maruyama calculates that only 0.23 billion metric tons are recovered. The balance is probably absorbed by lawsonite and other minerals forming 100 kilometers below the surface. (Hadfield, Peter; "Leaky Seas," New Scientist, p. 4, September 11, 1999.) Comment.

In this new book, Hoyle goes far beyond his previous thesis, which in essence declared that from statistical considerations life could not have arisen and evolved on earth. Rather, life had to come from outer space, probably in the form of bacteria and viruses. Evolution was and is dependent upon new information arriving from outer space on tiny bits of life. Hoyle now greatly extends his theory: "But where did a knowledge of amino acid chains of enzymes come from? To use a geological analogy, the knowledge came from the cosmological equivalent of a previous era, from a previously existing creature if you like, a creature that was not carbon-based, one that was permitted by an environment that existed long ago.

Here are found free-living bacteria, tube worms, molluscs, and several other species that prosper without the benefit of photosynthesis. These chemosynthetic, thermal-vent communities are separated by thousands of kilometers of sea-floor "desert." Yet, the species involved are similar worldwide and must, at some time, have crossed these wide, forbidding expanses. One possible mechanism for this mysterious dispersion came in 1987, when the research submersible Alvin chanced upon the remains of a 21-meter whale at a depth of 1,240 meters off California's coast. The whale's skeleton was covered with bacterial mats like those at the hydrothermal vents. Also sustained by the carcass were mussels, snails, and worms; all in all, a community much like those at the vents. Furthermore, many of the species partaking of the whale's energy and chemical resources are not normally found in that part of the Pacific. Subsequently, more "whale falls" with attached biological communities were found elsewhere. Calculations suggest that whale falls are more common that one might suppose -- perhaps occurring with average spacings of only 25 kilometers.

Although plate tectonics, nee continental drift, was ridiculed 50 years ago, it has been very successful in accounting for many geological phenomena. The theory is rarely challenged these days, but there are anomalies out there. "According to the simple plate-tectonic theory, the age of oceanic lithosphere is zero at a spreading oceanic ridge and increases with distance from the ridge. Thus the lithosphere of the central Atlantic, which current palaeogeographical reconstructions assure us began to open no earlier than 120 million years ago, has zero age at the Mid-Atlantic Ridge and, supposedly an age of about 120 million years close to the land masses of Africa and South America at the appropriate latitude. Yet, Bonatti and others (Nature, v. 380, p. 518, 1996) have now recovered samples of 140-million-year-old pelagic limestones not even from the edges of the Atlantic but right in the middle of the ocean, close to the ridge.

Mauna Kea (4201 meters), Mauna Loa (4201 meters), and other Hawaiian peaks penetrate high above trade inversion. Together they create a visible wind wake some 3,000 kilometers long to the west -- many time-greater than any other island wind wakes to be seen on the planet. The effects of these soaring peaks are more than visual. Their wind wake drives an eastward ocean current that, in turn, draws warm water away from the Asian coast 8,000 kilometers distant from Hawaii.

The Deep Sea Drilling Project discovered in 1970 and 1975 that layers of evaporites existed beneath the Mediterranean's floor. In addition, over 80 years ago, the bed of the Rhone River was found to consist of river sands and gravels superimposed upon hundreds of feet of oceanic sediments. Beneath these deposits -- some 3000 feet down -- was a gorge cut in granitic rock. Other rivers emptying into the Mediterranean had cut similar gorges into solid rock long ago. No one could provide an acceptable explanation for the deep-cut gorges until the evaporites proved that the water level had been low enough for the rivers to cut the gorges subaerially. In other words, the Mediterranean's level fell several thousand feet, allowing the rivers to erode gorges much as the Colorado does today in the Grand Canyon. (Smith, E.G .

The Expanding Earth Hypothesis goes back to at least 1933, a time when the Continental Drift Hypothesis was accorded the same sort of ridicule. Now, Continental Drift is enthroned; and ironically many of its strongest proponents are vehemently opposed to the Expanding Earth, ignoring the lessons of history. The data that suggest that the earth has expanded significantly over geological time come from the pleasant pastime of continent fitting. If one takes the pieces of continental and oceanic crust and tries to fit them together at various times over the past several hundred million years, taking into account the production of crust at the midocean ridges, the fit gets worse and worse as one works backward in time. Great gaps (or "gores") appear between the pieces of crust which geologists believed existed at these periods. (Of course, one can play this puzzle-piece game only at passive continent-ocean boundaries where the oceanic crust has not slid under the continental crust. The South Atlantic is a good place to work.) These embarrassing, grotesque gaps can be made to disappear almost as if by magic by assuming that the earth was smaller in the past.

Here, oceanic sediments are apparently being scraped off the oceanic plate as it thrusts under the North American plate. As a result, older Miocene deposits now overlie younger Pliocene deposits. Direct observations of the pressure in the zone where the shearing occurs showed it to be some 20 bars higher than the equilibrium pressure of 550 bars. This higher pressure may support the theory that low-angle thrust faults many kilometers wide are physically possible because high pressure fluids lubricate the shear zone, allowing massive thicknesses of sediments to slide over one another without resulting in wholesale fracturing and obvious damage. (Anderson, Roger, N.; "Surprises from the Glomar Challenger," Nature, 293:261, 1981.) Comment. Scientific creationists have long thought that the many low-angle thrust faults, where many miles of older rock are superimposed on younger rock, contradict geological dating schemes and therefore the theory of evolution. Establishment geologists, although somewhat amazed at the sizes of some of the overthrusts, especially one in Wyoming, have never despaired of finding a reasonable physical mechanism that would preserve the Law of Superposition and the idea of dating rocks by their included fossils. The Glomar Challenger results should buoy their spirits. Nev-ertheless, we must wonder how widespread stratum shuffling really is. What stratigraphic sequence is now immune ...

Since both sexes sing most of the year, the songs of the blue whale probably have nothing to do with reproduction. Then, why do they sing? A clue to the purpose of the blue whales' songs is found in their precision timing. One note is sung every 128 seconds. Furthermore, these notes (sound pulses) carry for hundreds of kilometers. C. Clark, a Cornell scientist, believes these notes are really sonar pulses used for fixing a whale's location. Echoes returned from distant seamounts, continental shelves, and other undersea topography enable the whales to map their positions within the wide ocean basins as they wander far and wide.

Did photosynthesis evolve at the earth's surface or deep in the oceans near hydrothermal vents? Such questions are engendered by the strength of the mysterious glow that emanates from these deep-sea vents. It is at these cracks in the ocean floor that very hot, mineralladen water gushes forth, and where colonies of bizarre tube worms, blind shrimp, and hyperthermophilic (high temperature-loving) bacteria thrive. (For details, see SF#60 or p. 238 in Science Frontiers, the book) The first anomaly is the strength of the glow itself. It is not all thermal radiation emitted by the 350 C water spewing forth from the vents; in fact, it is 19 times more intense than expected from theory. Something else is contributing energy, but no one knows what it is so far.

Are life forms in the vicinity of the vents employing photosynthesis? We don't know yet, but some bacteria do photosynthesize.

(SF#101) Geologists classify these slides as either "slumps" or "debris avalanches." Slumps move just a few inches a year but are prone to bigger, jerky adjustments. Debris avalanches are fast cascades of rocks and soil. In Hawaii, both varieties of movement can involve massive blocks of real estate. In the huge Nu'uanu debris slide, stone blocks 6 miles across tumbled 30 miles out to sea. Both slumps and debris slides may create colossal tsunamis. (Tsunamis are miscalled "tidal waves," but they have nothing to do with tides and do not behave like tides or wind-driven waves.) When large pieces of the Hawaiian Islands slip into the ocean, the entire Pacific Rim is smashed by the resulting tsunamis. In New South Wales, Australia, there is geological evidence that part of this coast was scoured by a Hawaiigenerated tsunami 100,000 years ago. The postulated wave started out about 375-meters ( -mile) high in Hawaii. By the time is reached Australia, it was about 40 meters high. (SF#85) Worse waves may be on tap. A 4,760 cubic mile chunk of the Big Island (Hawaii) is breaking away at the rate ...

It's a dark world, but it's also hot, permeated by fluids, and possibly the abode of organisms we haven't dreamed of. Three hints of this nether world follow. Quick oil. Rather than ripening in deep strata for millions of years, as per prevailing theory, some oil is being created in only a few thousand years in the vicinities of ocean-bottom chimneys. Dimesized oil globules have been sighted floating near these chimneys. Analysis of chunks broken off the chimneys by research submersibles reveal the presence of petroleum-like hydrocarbons that are less than 5000 years old. It is thought that high-temperature fluids percolating up through the sediments convert buried organic matter into oil very rapidly. (Monastersky, R.; "The Quick Recipe for a Soup of Black Gold," Science News, 136:295, 1989.) Comment. Not mentioned in this article is T. Gold's theory that oil is actually derived from primordial carbon deep in the crust. Gassy water. Some water wells in Texas also produce much methane. This methane is apparently not related to any oil or gas wells in the region. Rather, surmise has it that bacteria deep in the crust are converting buried organic material into methane and ...

"The discovery of a surprisingly high deuterium/hydrogen ratio on Venus immediately led to the speculation that Venus may have once had a volume of surface water comparable to that of the terrestrial oceans. We propose that the evaporation of this putative ocean may have yielded residual salt deposits that formed various terrain features depicted in Venera 15 and 16 radar images. "By analogy with models for the total evaporation of terrestrial oceans, evaporite deposits on Venus should be ar least ten to hundreds of meters thick. From photogeologic evidence and insitu chemical analyses, it appears that the salt plains were later buried by lava flows. 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 ...

There must be some structure and regularities in these streams of crashing fluid because waterfalls generate remarkable acoustical and luminous phenomena. First, we recall those curious pure acoustical tones that have recently been detected by seismic recorders in the ocean near French Polynesia. (SF#115) Geologist W.A . Charlie has associated these tones in the ocean with the strange but well-verified pure tones heard emanating from some waterfalls. Charlie recalls that the famous European geologist A. Heim observed that 15 Alpine waterfalls all produced two nonharmonizing groups of pure acoustical notes. These, a Zurich musician likened to the major-C triad and F. (Heim published his observations in a paper entitled: "Tone der Wasserfalle." Verhandlung der Schweizeren Naturforschung Gesellschaft, 8:209, 1874) In his letter to the magazine Earth (now defunct), Charlie wondered if the same resonant tonegenerating mechanism (rising clouds of bubbles) operated in both the oceans and waterfalls. (Charlie, Wayne A.; "Musical Monotones," Earth , 7:7 , June 1998.) Comments. In our catalog Earthquakes, Tides (GQV2), we recorded how waterfalls produce low-frequency terrestrial vibrations with one frequency predominating. This characteristic frequency is inversely proportional to the height of the waterfall. Just as fascinating are the remarkable flashes of light that emanate (rarely) from ...

South Atlantic Ocean. 2103 GMT on a clear dark night. "The first thing noticed was the formation of a bright patch of white light in the general area between Rasalhague and Alphecca. Gradually a dark eye formed in the centre of the patch in which shortly afterwards a very bright object appeared like a star of magnitude -2 . After one or two seconds this object appeared to undergo a tremendous explosion and became a large bright orange gaseous fireball, which appeared to be hurled earthwards directly down the observer's line of sight, growing constantly larger and larger. One witness described the fireball as resembling rolling orange smoke. The ball then ceased to increase in size, giving the impression that it had stopped. Its orange colour rapidly gave way to rainbow colours which gradually gave way to white and faded in brilliance until all that remained were several patches of luminous white light, although these were impressive in their own right." A similar phenomenon was noted the following night, although the ship was 7 farther south. September 18, 1982. South Atlantic Ocean. From a different ship in the same area as the one above. "The altitude of the first sighting was approximately 24 , level with the planet Jupiter and offset to its right.

Mar-Apr 1997 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Did a methane burp down twa800?The potential for methane eruptions from offshore sediments to sink ships and down aircraft was proposed by W.D . McIver way back in 1982, in the Bulletin of the American Association of Petroleum Geologists. (SF#25/208) The source of methane-gas releases (" burps") is the rapid decomposition of methane hydrate, which exists in prodigious quantities in offshore sediments. Some geologists have estimated that there is twice as much methane in methane-hydrate deposits as in all terrestrial natural-gas fields. What makes methane hydrate potentially lethal is its instability. Landslides and small quakes can release huge plumes of methane bubbles into the ocean and thence into the atmosphere. Ships might founder in the lowdensity froth of bubbles, and aircraft might be adversely affected, too. This is where TWA800 comes in. R. Spalding, a scientist at Sandia National Laboratories has been monitoring mysterious atmospheric explosions and believes that some of these detonations are consistent with the atmospheric ignition of huge methane plumes. (Other detonations are due to meteors.) Spalding proposes the following scenario: The ocean floor releases a massive methane gas plume, which rapidly rises to the surface and ascends into the atmosphere. The lighter-than-air methane cloud gains altitude, mixing with oxygen and thereby gaining explosive poten tial. An electrical disturbance -- possibly caused by the rising cloud itself or a lightning strike -- detonates the cloud. Awesome energy is ...

It all began when the container ship Hansa Carrier , enroute from Korea to the U.S ., encountered a fierce storm and lost 21 40-foot-long containers to the sea. "Approximately 80,000 Nike brand shoes were lost overboard on May 27, 1990, in the north Pacific Ocean ( 48 N, 161 W). Six months to a year later, thousands of shoes washed ashore in North America from southern Oregon to the Queen Charlotte Islands...We have gathered beachcomber reports and compared the inferred shoe drift with an oceanographic hindcast model and historical drift bottle returns. This spill-ofopportunity provided a calibration point for the model. Computer runs for 1946-1991 suggested that drift of floatable material across the northeast Pacific Ocean for May 1990-January 1991 was farther south than the mean of forty-five simulations." Route of the floating shoes Well, we can tweak the model a bit; but the authors added a postscript: "As we were finishing this article, we received reports of shoes arriving at the northern end of the Big Island of Hawaii. These shoes appear to have followed the California current southward, and then traveled westward." (Ebbesmeyer ...

Spacecraft photos have revealed curious striations in the Andaman Sea near Thailand. They are presumed to be examples of solitary waves. The Andaman waves extend for many miles and travel very slowly -- less than 10 kilometers per hour. They propagate along the boundary between the layer of warm surface water and the great mass of cooler water below. The amplitude of the downwardly pointing wave troughs of warm water along this interface may penetrate as far as 100 meters into the cold water below. (Herman, Russell; "Solitary Waves," American Scientist, 80:350, 1992.) Comment. Much more about these solitary waves and the other unusual waves mentioned above may be found in section GHW in our catalog: Earthquakes, Tides, Unidentified Sounds . The prevailing explanation for most oceanic solitary waves (often called "solitons") is that they are generated when tidal surges encounter underwater continental shelves or other obstructions.

Science Frontiers ONLINE No. 124: Jul-Aug 1999 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Photosynthesis At Deep-Sea Vents The surprisingly rich populations of lifeforms that prosper around the hydrothermal vents have been thought to be utterly dependent upon chemical energy for their survival. Such now seems to be a limited view. There is light at the bottom of the ocean! "Of particular interest is the potential for deep-sea vents and subsurface environments to support geothermally (rather than solar-) driven photosynthesis. Recent work on ambient light conditions at hydrothermal vents indicates that the photon flux generated by thermal radiation of 350 C water should be sufficient to sustain lowlevel photosynthesis, and there is at least one report of a faculative phototroph isolated from water samples taken near a deep-sea vent." A particularly important implication of this undersea light source is that the evolution of photosynthesis need not have been dependent upon the existence of life on land. Also, hydrothermal vents could have served as refuges for photosynthesizing life forms down the geological eons when: (1 ) ocean surfaces were ice-covered; (2 ) the terrestrial surface was exposed to deadly levels of radiation, as when the ozone layer was destroyed; and (3 ) when volcanism or dust from meteor impacts blackened the skies.
