But, according to NASA's R. Bindschadler, an ongoing study of the Antarctic coast near the Ross Ice Shelf casts doubt upon this assumption of long-term stability. Measurements of one ice stream flowing down from the mountains to the sea in dicate a sudden unexplained, 20% reduction in speed over the past decade. Perhaps even more significant is that, even with this reduction in flow velocity, this particular ice stream carries ice into the sea 40% faster than ice accumulates up in the mountains. The sudden, rather large velocity change is alarming because it may signify widespread instability in the continent's icy mantle. Researchers state that there is even a chance that much of the Antarctic ice cap could collapse into the sea in the next few centuries -- a catastrophic event that would raise global sealevels by 6 meters!

... year-old American captain of the ship, shortened the sails. The Marques was carrying a crew of 28 - half of whom were under 25. At the helm, Philip Sefton, 22, fought the angry waves that now confronted them. "Suddenly a heavy gust of wind pushed the Marques down on its starboard side. At the same instant 'a freakish wave of incredible force and size,' as Sefton later described it, slammed the ship broadside, pushing its masts farther beneath the surging water. A second wave pounded the ship as it went down. The Marques filled with water and sank in less than one minute. Most of the crew were trapped as they slept below deck. Only Sefton and eight shipmates survive." Accounts such as that above are part of sea lore. Waves 50-100 feet high have been frequently reported over the years.

Perhaps it needs a flexible shell for its very deep dives. What looks like a shell is its thick, leathery carapace -- a strange streamlined structure with five to seven odd "keels" running lengthwise. These turtles are warm-blooded , and able to maintain their temperatures as much as 10 F above the ambient water, just as the dinosaurs apparently could. The bones of the leatherback are more like those of the marine mammals (dolphins and whales) than the reptiles. "No one seems to understand the evolutionary implications of this." Leatherbacks dive as deep as 3000 feet which is strange because they seem to subside almost exclusively on jellyfish, most of which are surface feeders. Like all turtles, leatherbacks can stay submerged for up to 48 hours. Just how they do this is unexplained. Their brains are miniscule.

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."

Actually, it could be even 500-3000 years younger than that for two reasons: (1 ) The organic debris that was C-14-dated may have taken many years to become incorporated in the sediments; and (2 ) The dating may be skewed by older material in the sediments. By subtraction, the oil might be as young as 1240 years! The picture geologists draw of the Guaymas Basin is that of a spreading center covered by perhaps a half kilometer of sediments. Spewing up from the spreading center is hot water at 300-350 C, which "cracks" the organic material in the sediments, converting it into petroleum only 10-30 meters below the sea floor.

These muffled detonations heard near the coasts of almost all the continents are believed by some to be caused by eruptions of methane from the seafloor. The same eruptions probably also account for the myriads of "pockmarks" found in the sediments of shallow seas. Whether this outgassing of methane comes from shallow accumulations of organic matter or from deep within the crust is still debated. Here, geophysics merges with biology. Recently, a group of researchers discovered a large (540 square meters) patch of chemosynthetic mussels in a brine-filled pockmark, at a depth of 650 meters, off the Louisiana coast. The mussels grew in a ring around the concentrated brine. The mussels harbor symbionts which consume the methane still seeping up through the brine from a salt diapir (a massive fingerlike intrusion 500 meters below the brine pool. The origin of some diapirs is not well-understood.) The mussels get the oxygen they require from the ordinary seawater covering the dense brine. Like the biological communities surrounding the "black smokers" and other ocean-floor seeps, the brine-filled pockmark community includes several species of shrimp, crabs, and tube worms.

A meticulous new study of central European stratigraphy now pegs the Pennsylvanian as spanning only 19 million years. Now that's a 44% change! This new figure for the duration of the Pennsylvanian has already cast doubt on the origin of the famous Pennsylvanian cyclothems (repetitive strata) in North America. It had been thought that these seemingly cyclic deposits were correlated with sea level changes forced by variations in the earth's orbit (the Milankovitch periods). With this substantial compression of Pennsylvan-ian time, this correlation falls apart.

A group of researchers, led by oceanographers from the University of Washington, detected faint light during an expedition to the Juan de Fuca Ridge. The ridge and the vents, 300 km off the coast of British Columbia, follow an underwater fault formed by the junction of the Juan de Fuca and the Pacific tectonic plates...John Delaney, leader of the expedition, described the glow as a 'flame-like light' that seems to emanate from the super-heated water emerging from the thermal vents, 2200 meters below the surface...'The source of the light is still unclear,' said Joe Cann, a geologist from the University of Newcastle in Britain. The scientists suspect that the water itself is glowing." The water temperature is so high -- 350 C -- that bioluminescence is unlikely. The presence of the glow does, however, imply that photosynthesis is still possible in these sunless depths. Life forms do congregate around these vents. A curious shrimp found in the area where the glow was noted is eyeless but does possess photoreceptors on its back!

The songs of humpback whales can change dramatically from year to year, yet each whale in an oceanwide population always sings the same song as the others. How, with the form changing so fast, does everyone keep the verses straight? Biologists Linda Guinee and Katharine Payne have been looking into the matter, and they have come up with an intriguing possibility. It seems that humpbacks, like humans, use rhyme." Guinee and Payne suspect that whales rhyme because they have detected particular subphrases turning up in the same position in adjacent themes.

The effect is sometimes quite dramatic. There are accounts of a 'low roar' as the bands of breaking waves, 'walls of white water,' pass a vessel. The bands are sometimes visible from aircraft, on ships' radar and are observed from satellites. In the Bay of Biscay 'boils' have been reported on the sea surface in the calm zones, and appear to be related to pulses of nutrients from the thermocline." These surface phenomena are truly delightful and almost always the consequence of internal waves interacting with the surface.

While volcanic eruptions form most sea-mounts, these mountains consist of a nonvolcanic rock called serpentinite, and oceanographers are not entirely sure how the serpentinite mountains formed." The theory of plate tectonics has the Pacific plate diving under the Philippine plate along the Mariana trench. It may be that water trapped in the downgoing crust leaks out, rises, and serpentinizes the crust above. This altered rock, being lighter than that surrounding it, may slowly rise through it, eventually forming undersea mountains. (Monastersky, Richard; "Novel Mountains and Chimneys in the Sea," Science News, 134:333, 1988.) Comment. This all sounds pretty speculative, but those mountains had to come from somewhere. Perhaps the serpentinite mountains are just one manifestation of a larger phenomenon: the chaotic slithering and popping up and down of crustal material.

Ever since this apparent synchrony was recognized a few decades ago, theorists have been vying in generating scientific scenarios, especially some mechanism that would reverse the earth's magnetic field. New entrants in the lists are R. Muller and D. Morris, two Berkeley physicists. Here is how they see it: "A sufficiently large asteroid or cometary nucleus hitting the Earth lofts enough dust to set off something like a 'nuclear winter.' The cold persists long after the dust settles because of the increased reflectivity of the snow-covered continents. In the course of a few centuries, enough equatorial ocean water is transported to the polar ice caps to drop the sea level about 10 meters and thus reduce the moment of inertia of the solid outer reaches of the Earth (crust and mantle) by a part in a million. 'That doesn't sound like much, Morris told us. 'But when we realized that this translates into a full radian of slippage between mantle and core in just 500 years, we began to look seriously at the consequences.' With the moment of inertia of the crust and mantle 'suddenly' decreased, the argument goes, they begin spinning faster than the solid-iron inner core at the center of the Earth. The 2300-km thick shell of liquid outer core that separates the mantle from the inner core thus acquires a velocity shear, which in the course of about a thousand years destroys the ...

They are not using the directional information of the Earth's field, as we do with our compasses, but small relative differences in the total local field. I arrived at this explanation after a detailed analysis of the records of strandings in Britain, but it has so far been confirmed by two groups working in the U.S . Similar work is in progress in other parts of the world. "The total magnetic field of the Earth is not uniform. It is distorted by the underlying geology, forming a topography of magnetic 'hills and valleys.' My analysis shows that the animals move along the contours of these magnetic slopes, and that in certain circumstances this can lead them to strand themselves. In the oceans, sea-floor spreading has produced a set of almost parallel hills and valleys. Whales could use these as undersea motorways, but might swim into problems when they came near the shore, because the magnetic contours do not stop at the beach. They continue onto the land, and sometimes so do the whales." In addition to stranding because of land-intersecting contours, unpredictable changes in the earth's magnetic field can upset the whales' timing mechanism, causing them to lose their true position on their magnetic dead-reckoning maps. Magnetically speaking, they become lost. (Klinowska, Margaret; "No Through Road for the Misguided Whale," New Scientist, p. 46, February 12, 1987. Also: Ellis, Richard; "Why Do Whales Strand?" ...

I looked to port to see what type of cloud could obscure the moon so thoroughly, and was amazed -- horrified, rather, to discover it was no cloud, but an immense wave approaching on our port beam. It stretched far north and south, had no crest, nor white streaks, and as it neared at quite a speed, I could see its front was nearly vertical. I yelled to the lookout man to come into the wheelhouse as he was on the starboard side of the bridge and could not see the wave. "As near as I could judge, about 80 to 100 yards away the wave started to break, and in another few seconds reached our ship and struck us fair abeam with three distinct separate shocks, sweeping our ship for her full length. Fortunately, the vessel rolled away just before the impact and this I am sure saved us from even more serious damage." "The wave was higher than our foremost track -- 85 ft above the water. As this wave approached ...

Some of these deep-sea traps measure 6 x 6 x 3 feet and are used to catch large shrimp (about 1 foot long) and crabs (2 feet, claw to claw). Something down there grabs these traps and refuses to let go. A giant octopus is believed to be the culprit.

Some 322 tsunamis have been recorded in the Pacific between A.D . 83 and 1967 -- or about one every six years on the average. The surprising thing is that tsunamis are more common in November, August, and March, but rarer in July and April. Offhand, no good explanation comes to mind why sea floor quakes should favor some months over others. (Anonymous; "The Times for Tsunamis," Science News, 127:88, 1985.)

Equatorial Eastern Atlantic. "Whilst the vessel was approaching the equator, on a course of 023 and at a speed of 10.3 knots, flashing white lights were observed. The sea was rippled, with a low NW'ly swell and the wind light airs. The visibility was good, with the moon in its first quarter. At first it was thought that there were three lights, one being bright and the other two relatively dim, but as the vessel approached it it was decided that there were only two, one bright and one dim. "The radar, a 10-cm S-band Decca, was switched on and a single echo was detected initially at a range of 5 n. mile. By this time the lights had already been observed for halfan-hour, so it was estimated that they had first been observed when they were 10 n. mile distant. The time of the first sighting was 2220 GMT. The target, once detected, gave a very strong echo and gave the impression of being a large target. It was plotted and found to be stationary. The initial course of 023 was altered to 028 in order to enable the vessel to close the passing distance. "Throughout the observations neither light followed any set characteristic. Instead they just flashed at random, but never together. The intensity of the bright light would have ...

Related Amphipods are not only found in Bahamian caves but in marine caves in Bermuda, the Pacific, and the Yucatan Peninsula."

Science Frontiers ONLINE No. 45: May-Jun 1986 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects The Gulper Eel And Its Knotty Problem Occasionally brought up from great depths in nets, the gulper eel consists mainly of a huge mouth followed by a large bag of skin and, finally, a very long thin tail. The eel, often 6 feet long, can swallow prey as large or larger than itself. 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? (de Sylva, Donald P.; "The Gulper Eel and Its Knotty Problem," Sea Frontiers, 32:104, March-April 1986.) Comment. We cannot resist mentioning the occasional discovery of groups of rats all tied together by their tails. Called "rat kings," these hapless snarls of rodents are usually dismissed as pranks or outright prevarication. How-ever, in recent years, respected naturalists have found "squirrel kings" in the wild. Gulper eels are not the only animals with knotty problems.
