Only when we get the flu or infected finger do these entities impinge upon our consciousness. Below we will learn that there are many more of them than you think. Do viruses control the oceans? You may avoid the beaches after you learn that one teaspoon of seawater typically contains 10-100 million viruses and onetenth that many bacteria. Obviously, most are harmless to humans. However, the viruses do infect the bacteria and phytoplankton, destroying them, and thereby releasing their nutrients. By doing this, they keep the oceans' biological engines running. Further, the viruses act as genetic engineers as they transfer DNA from one individual to another. The oceans may be viewed as vast test tubes in which biodiversity is maintained by teeming, invasive viruses. (Suttle, Curtis A.; "Do Viruses Control the Oceans?" Natural History, 108:48, February 1999.) We are only 10% human! The average human body contains 100 trillion cells, but only 1 in 10 of these cells is your own. The remaining 90% are bacteria.

... course, it will be a contentious, long-drawn-out transition; but it is as dramatic in archeology as the discovery of X-rays was in physics a century ago. The artifactual basis for the Solutrean Hypothesis consists of projectile points and blades found along the east coast of North America that are virtually indistinguishable from those manufactured by the Solutrean culture that flourished in Spain, Portugal, and southwestern France 20,000 years ago. Promoters of the Solutrean Hypothesis assert that adventurous inhabitants of the Iberian Peninsula made Atlantic crossings in skin boats. With the help of the favorable currents and benign weather, they could have made the crossing in about three weeks. Diehard champions of the Bering Land Bridge ridicule such early trans-Atlantic crossings. Yet, South Pacific islanders had been making long ocean voyages for some 20,000 years before the Solutreans set sail. No one denies that some immigrants to the Americas used the Bering Land Bridge; it is just that they were latecomers. Archeological sites in Pennsylvania, Virginia, and South Carolina (SF#125) dating back 15,000-18,000 years demonstrate that the ocean-going Solutreans had footholds in the Americas 3,0006,000 years before Asian landlubbers trekked into Alaska.

These stripes across the planet's southern highlands are a great surprise to planetologists because they superficially resemble the magnetic stripes that parallel the rifts along the floors of the earth's oceans where new crust is forming. The obvious implication is that Mars once possessed drifting continents and a geomagnetic dynamo that occasionally reversed its polarity -- just as has supposedly happened and is still happening on earth. Prior to this discovery, Mars was deemed too small to have possessed a heat-driven geodynamo, and there is no obvious surface evidence of drifting continents. Easy as it is to conclude that Martian continents once sailed ponderously cross the planet's surface, the scientific jury is still out. First of all, the Martian magnetic stripes are substantially different from earth's in shape, pattern, strength, and, above all, size. The Martian stripes are about 200 kilometers wide and 2,000 long -- much larger than earth's . Their magnetic field strength is more than ten times that of the terrestrial stripes. Whatever magnetic phenomena occurred on Mars some 4 billion years ago must have been quite different from what happened on earth 200 million years ago. Yet, no other reasonable explanation has been found for the ...

The inhabitants of this island have generally ignored these dilapidated piles of black volcanic stones. However, one perceptive native described them in a letter to T. Heyerdahl of Kon Tiki fame and a leading proponent of ancient cultural diffusion across all oceans. Quick to respond, Heyerdahl perceived amid the debris six stepped pyramids of black stone. He persuaded a Norwegian businessman to buy the site, clean up the debris of centuries, and found a museum. One of the "black" pyramids has now been restored, but some experts are still unconvinced. However, recent excavations under one pyramid have yielded artifacts identified with the pre-Spanish inhabitants of Tenerife. Meanwhile, Heyerdahl has been checking out a rumored pyramid on Sicily. Could Heyerdahl be right when he claims there were age-old cultural links between Mesopotamia, Egypt, Mexico, the Canaries, and even the Pacific Islands?

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. (SF#44) Critics claimed that these "holes" were no more than instrumental errors. L.A . Frank and J.B . Sigwarth have investigated this possibility and have rejected it. (Frank, J.A ., and Sigwarth, J.B .; "Atmospheric Holes: Instrumental and Geophysical Effects," Journal of Geo physical Research, 104:115, 1999. Cr. P.

Mars is now red because of its endless vistas of reddish soil and rocks, But most planetary scientists now insist that Mars was once blue, too. It was drained by gushing rivers and supported a vast ocean. The planet's many channels and layered deposits seem to prove Mars was, like Earth, once a water-rich planet. 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. Surface photos fail to show the fine networks of tributaries that should have fed the larger drainage features if water were the agent of erosion. There is no evidence of large lakes or reservoirs at the heads of the so- ...

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.

Green St. Elmo's fire was glowing on the aerials. "At about 2310 it was also noted that the lever extending about 18 cm over the ship's starboard bridge wing to position a deck light was also radiating light. This light was a pale violet glow extending in 'spokes' of 10 cm in length from the round end of the lever which was about 3 cm in diameter. "There were six individual and uniform spokes shot through with brighter purple and white bolts resembling lightning. Over the noise of the wind a sharp crackling and hissing sound could be heard coming from the phenomenon. "The seaman was called to have a look at the light, he attempted to touch it but the light receded as his finger approached within 3 cm of it. The effect died away at about 2340 as soon as rain started to fall." (Smedley, R.; "Corposants," Marine Observer, 69:55, 1999.) Comments. The corposant's six-fold symmetry is like that of snowflakes.

Two showed a very interesting phenomenon, because while the vapour trails extended eastwards, the trails were continued westwards in front of the planes as dark lines which stretched all the way to the horizon. It was as if the plane was running on an aerial railway. I think it significant that only two of the planes showed this phenomenon as I suspect it was heightdependent. At this time the sun was high and shining from the south-southwest." J.O . Mattsson, Lund University, surmised that the black streaks in front of aircraft were shadows of the condensation trails behind the two planes. The shadows were cast forward ahead of the planes upon the hazy, though cloudless, atmosphere above the ocean. (Evans, Alun; "Condensation Trail Shadows," Weather, 53:371, 1998.) Comment. Since the sun was high in the sky, it is difficult to visualize how a the vapor-trail shadow could be cast directly ahead of the aircraft. Hummm!

... could not call itself a science if it permitted ideas like continental drift to run rampant. Of course, the situation has now been reversed as some scientists plead that data contradicting plate tectonics should no longer be accepted for publication! Happily, at least one publication is still open to heretics. In a 1997 number of New Concepts in Global Tectonics , we find S. Keshav, at Bombay's Indian Institute of Technology, asserting that plate tectonics is a "myth that has paralyzed our thinking." And he gives some reasons for his view: Plate tectonics incorporates many physically impossible processes, such as sediment subduction; i.e ., soft sediments should be scraped off plates as they dive beneath the continents. Plate tectonics does not completely explain the ophiolites (rocks resembling bits of ocean crust that are sometimes found in embarrassing places (far inland). Plate tectonics has difficulty accounting for some mountain belts; i.e ., those far from collisional sites, like Tibet's Kunlun mountains. Finally, Keshav observes: "On the continents this theory assumes mysterious character as many of the features go unexplained (as exemplified by inability to find a trace of the Asthenosphere/Moho) and truly depicts an act of escapism." (Keshav, Shantanu; "A Myth Called Plate Tectonics," New Concepts in Global Tectonics , p. 23, no. 3, June 1997.) Comment.

The aquatic-ape hypothesis may or may not hold water, but modern sonar undersea imaging and sampling reveal wide swathes of land that are now drowned that could once have been ideal habitat for water-adapted humans. One of these surveys was conducted offshore of Queen Charlotte Island, Canada. The surveyors discovered extensive post-glacial landscapes suitable for human use now covered by 150 meters (500 feet) of ocean, but which were exposed 10,000-12,000 years ago. In situ tree stumps and shellfish-rich paleobeaches are present on these drowned landscapes. A stone tool encrusted with barnacles and bryozoa were recovered from a drowned delta flood plain now 53 m below mean sea level. This is the first tangible evidence that the subaerial broad banks of the western North American Continental Shelf may have been occupied by humans in earliest Holocene and possibly late glacial time.

South Atlantic Ocean. Aboard the m.v . Appleby enroute from Long Beach to Port Talbot. "At 2225 UTC when a light rain shower was falling, a rainbow was seen on the starboard side roughly 2-3 cables from the vessel. It was very clear for about six minutes and was accompanied by a secondary bow after about half that time. The secondary one did not make a complete bow but seemed joined to the primary bow at its highest point, in a convergence area of deep blue, as indicated in the diagram. "The colours were very clear, with blues and purples visible in both parts. Both bows began to fade at about the same time as the moon once again passed behind another cloud." (Crofts, A.; "Lunar Rainbow," Marine Observer, 69:67, 1999.) Comments. Because moonlight is much weaker than sunlight, lunar rainbows are rather rare. Even so, they are not anomalous. It is the offset bow that is difficult-to-explain. Rainbow phenomena should be symmetrical around the line containing the light source (moon, here) and the bow itself. In GEB3 in Rare Halos, we note that no reasonable explanation exists for rainbows offset to one side. However, extra bows offset directly above the main bow can be explained as due to reflection of moonlight or sunlight off ...

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.

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 search has revealed that at six times during the last glaciation, huge armadas of icebergs launched from Canada spread across the northern Atlantic Ocean, each triggering a climate response of global extent." The foregoing abstract does not mention the interesting Heinrich layers that fostered the above scenario. In 1988, H. Heinrich published a paper describing a curious set of sedimentary layers found in cores drilled in the tops of the Dreizack seamounts in the eastern North Atlantic. Heinrich concluded that each of the six layers he found represented the melting of "six great armadas of icebergs." These icebergs carried debris picked up in Canada and, as they melted, deposited it on the seamounts and ocean floor. Each layer could be correlated with the major climate boundaries revealed by the Greenland ice cores. Very fittingly, these iceberg incursions are now termed "Heinrich Events."

They occur worldwide on the floors of all of the oceans and even some lakes. They are found in shallow waters and at depths of thousands of meters. In diameter, these roughly conical depressions may span 350 meters or more and be up to 35 meters deep. No trivial phenomenon, some pockmark fields exceed 1,000 km2. Like the curious abyssal ridges (SF#97), sea-bed pockmarks are rarely discussed despite their great geological and economic importance.

The oceans, however, also move in ponderous cycles that beachcombers can never appreciate. Thanks to data from Geosat's precision altimeter, geophysicists can now discern some of these long-period moving patterns on the oceans' surfaces. "Energetic 90-day oscillations of sea levels have been intermittently observed at Wake Island in the western tropical Pacific during the past 2 decades. The oscillations tend to occur about 1.5 years after El NinoSouthern Oscillation events, to have amplitudes of 10-15 cm, and to persist for about 1 year. Sea-surface heights from the Geosat altimeter are used to establish that these signals take the form of Rossby waves and have an energy source near the Big Island of Hawaii, which lies 40 of longitude to the east. Sea-level and upper-layer currents from an eddy-resolving numerical model are examined and suggest that the energy source is eddies generated off the Big Island of Hawaii. These eddies appear to be associated with westward currents that intermittently impinge on the island."

Twenty years ago, biologists put the number of species at about 1 million. Then, they started shaking and gassing rain-forest canopies. The rain of new insect species that fell to the ground made them revise the estimate to 30 million. The latest, long-unappreciated reservoir of undescribed species is mud -- oceanic mud. In particular, we know that the mud in the Rockall Trench off the western coast of Scotland teems with untold species of diminutive nematodes. Of course, nematodes are not as pretty as birds and fish, but they are nevertheless bona fide species of life. Examination of the Rockall mud and that from other seabed sites has convinced the nematode counters that there may be as many as 100 million nematode species on our planet. When other classes of life are added, the figure rises to at least 130 million. (Pearce, Fred; "Rockall Mud Richer than Rainforest," New Scientist, p. 8, September 16, 1995.) Comments.

We hear a lot about the endless steppes of Asia and the immensity of the Sahara, but who writes about the earth's dominant geomorphological feature? The abyssal hills are left out of the textbooks because so little is known about them. They are hidden under 3 kilometers of water.

If we could see them visually, they would probably look like the Appalachians from an airplane; that is, wash-board-like. Although heavily draped with pelagic sediments, the abyssal hills are believed to have been shaped by faulting and volcanic activity. K. MacDonald and coworkers at the University of California, Santa Barbara, now believe that both processes are involved: "On the basis of data obtained last January on a series of dives along the East Pacific Rise (EPR), a ridge that runs off the coast of Central and South America, researchers theorize that the linear ridges of abyssal hills, which decorate the ocean floor somewhat ...

These are the rays that penetrate to the greatest depths in the sea. This adaptation to blue light means that deepsea fish have evolved visual pigments different from those of surface fish and land animals. Visual pigments are complex chemical compounds, and one must suppose that many, many random mutations took place before deepsea fish were able to manufacture visual pigments different from their relatives living near the surface. (Or did deepsea fish come first?) But there is more to this story. Many dwellers in the black abysses generate their own light. They sport bioluminescent organs so they can be seen by others of their own species and, in addition, illuminate prey for easier capture.

This observation runs contrary to a major tenet of plate tectonic theory -- that the motion of lithospheric plates is essentially independent of flow in the upper mantle beneath the plates -- and implies that the upper mantle and the overlying South American continent have remained coupled since the breakup of the Gondwanaland super-continent and opening of the South Atlantic

The specific diamonds suspected to have an organic origin are the so-called "eclogitic" diamonds. These diamonds may have obtained their carbon and impurities from bacterial communities that once lived around hydrothermal vents that existed along ancient mid-ocean ridges. Subsequent metamorphism (heat and pressure) turned the masses of bacteria into eclogitic diamonds. So, those sparklers of yours may just be clumps of billion-year-old bacterial corpses!

... ignore data chauvinists) is that we should somehow use all the available information to infer the correct phylogeny. After all, there was just one real phylogeny that occurred in the past, and we want to find it as closely as we can." Comment inserted by the compiler. Van Valen is saying that three evolutionary Trees of Life can be drawn from adult morphology, DNA structure, and larval morphology, and that they may not look the same. Caterpillars may yield a family tree different from that inferred from the butterflies. Which is correct, or are they all correct? Back to the review. Waxing heretical, Williamson points out that an organism may have more than one phylogeny ! Larvae may have ancestries different from the adults. How heretical can one get? But in the ocean, spermatozoa often cannot find an egg of the correct species. They may then fertilize eggs of a distantly related species. In such "wide hybrids," the larvae may resemble one parent and the adults the other. There is much more. The gist of it all is that evolution has been much more than random mutation and natural selection. Hybridization and outright mergers (endosymbiosis) have played important roles. Even our own cells harbor mitochondria that have their own DNA. They are probably bacterial invaders that long ago settled down in the cells of our ancestors.

The subtitle quoted below implies that we are not discussing the supposed lost continent of Mu. "Riddle of the Submarine Ruins in the Ryukyu Islands" Rather, the underwater site is that introduced in SF#118 and located southwest of Okinawa. It is hardly the size of a continent. The book's author is Masaaki Kimura, and he has filled his book with stunning underwater photographs and diagrams of this "lost continent." Unfortunately, except for a Contents page, which is in English, the rest of the book is in Japanese. We'll have to settle for the Contents page, which is rather revealing. Human Beings under the Sea The Submarine Ruins Discovered Were the Ryukyu Islands a Continent? Discovery of a Civilization Lost in the Sea An Ancient Civilization in Southernmost Japan A Continent Lost in the Pacific Ocean Submersion of the Land and Tectonics of the Earth Hypotheses for the Land Lost in the Pacific Ocean A Utopia Sunk in the Pacific Ocean Pretty inflammatory stuff, so much so that we must be wary indeed! One of the drawings in our photocopy is good enough to reproduce here. The immediate impression, as with many of the underwater photographs, is that surely this structure is artificial. But we must remember that Nature has her playful moods and has deposited simulacra everywhere, perhaps even ...

... Science Frontiers ONLINE No. 118: Jul-Aug 1998 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Glitches In The Terrestrial Conveyor Belt According to plate tectonics, the earth's continents are being transported -- very slowly -- on a subterranean conveyor belt of sorts. 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. How can this be possible?" The only explanation (? ) seems to be that this errant chunk of crust got "trapped" in the middle of the Atlantic -- like a misdirected suitcase on an airport conveyor belt. (Anonymous; "Old Rocks near the MidAtlantic Ridge ...
