Nansen in his epic attempt to reach the North Pole at the end of the last century. Nansen first endeavored to go as far north as he could in his specially constructed vessel, the Fram . It was on the Fram that he struggled with "dead water." J.M . Walker, drawing from Nansen's marvelous written account Farthest North , describes the phenomenon: "Towards the end of August 1893, when Fram was off the Taymyr Peninsula, near the Nordenskiold Archipelago, 'dead water' was encountered. In the words of Nansen, this is 'a peculiar phenomenon', which 'occurs where a surface layer of fresh water rests upon the salt water of the sea, and this fresh water is carried along with the ship, gliding on the heavier sea beneath as if on a fixed foundation'. It 'manifests itself', he observed, 'in the form of larger or smaller ripples or waves stretching across the wake, the one behind the other, arising sometimes as far foward as almost midships'. When caught in dead water, Nansen reported, Fram appeared to be held back, as if by some mysterious force, and she did not always answer the helm. In calm weather, with a light cargo, Fram was capable of 6 to 7 knots. When in dead ...

Even less acceptable is the notion that over the eons these house-sized chunks of ice contributed substantially to our planet's inventory of water. In what will surely be hailed as the death knell of the icy comet theory is the discovery by K. Muehlenbachs, of the University of Alberta, and F. Robert and M Javoy, from the University of Paris, that the water contained in the earth's rocks, both ancient and recent, is isotopically different from the water found in meteorites. Meteoric water is assumed to be isotopically the same as cometary water. Conclusion: comets could not have contributed substantially to our planet's water inventory in the geological past. (Anonymous; "Earth's Water Did Not Come from Comets," New Scientist, p. 19, June 20, 1992.) Comment. Of course, the isotpic measurements have to be weighed against all the data supporting the icy comet theory Icy comets could, after all, be a recent phenomenon. Also, no one has ever actually analyzed a piece of cometary ice; it is simply assumed that it would be similar to meteoric water. From Science Frontiers #83, SEP-OCT 1992 . 1992-2000 William R.

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. The fluid contents of fresh eggs, however, will slosh around and prevent top action. 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 top layer is electrically resistive, seismically transparent, the source of almost all earthquakes, and responds to stress elastically. In contrast, the lower crust is electrically conductive, contains many reflectors of seismic energy, provides few quakes, and responds like a ductile material to stress. The diverse characteristics of both regions can be explained if the entire crust contains saline water. In the up-per crust the water is thought to be in separated cavities, while deep down it forms an interconnected film on crystal surfaces. (Gough, D.

Well, it's worth a try! G. Rein and R. McCraty, of the Institute of HeartMath, first define two physiological states: "We have recently defined two new physiological states in terms of their unique electrophysiological characteristics. These states are generated using specially designed mental and self-management techniques which involve intentionally quieting the mind, shifting one's awareness to the heart area and focussing on positive emotions. Time-domain and frequency spectral analysis of heart rate variability, pulse transit time and respiration were used as electrophysiological measures of these states." Next, the two researchers brought together subjects immersed in one of these states and samples of water: "The present study reports on PK [psychokinetic] effects associated with these intentionality states. ECG monitoring was used to demonstrate when the individuals were in the entrained state. At this point a sample of distilled water in a sealed test tube was presented to the subjects. Five individuals were used in this study...While holding a beaker containing the samples, subjects were asked to focus on the samples and intentionally alter the molecular structure for five minutes.

This gigantic terrestrial easel covers 400 square miles. Upon it are drawn more than 1,000 biomorphs and geoglyphs, plus some 800 straight lines.

A lengthy, comprehensive report of this research has been published in two issues of the Journal of Scientific Exploration. We now quote from that part of the abstract dealing with field experiments in several countries. "This report presents new insights into an unconventional option of locating water reserves which relies on water dowsing. The effectiveness of the method is still highly disputed. Now, however, extensive field studies -- in line with provable and reliable historic account -- have shown that a few carefully selected dowsers are certainly able to detect faults, fissures and fractures with relative alacrity and surprising accuracy in areas with, say, crystalline or limestone bedrock. A series of Deutsche Gesellschaft fur Technische Zusam menarbeit (GTZ) projects involving this technique were carried out in dry zones with unexpectedly high rates of success. In particular, it was possible to locate a large number of relatively small underground aquifers in thinly populated areas and to drill wells at the sites where water is needed; the yields were low but sufficient for hand-pump operation throughout the year. Finding or locating a sufficient number of relatively small fracture zones using conventional techniques would have required a far greater work input." A second part of the study involved controlled experiments in which dowsers tried to detect concealed targets such as pipes. ( ...

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.

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.

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.

Both are based on sound geological research: deep-sea cores, seismic profiles, and the like; but the reconstructions of the events are on the speculative side, particularly in matters of the magnitudes of the effects. Both events also purport to explain long-standing puzzles. Scenario #1 . The Bosporus silt plug blows. During the last Ice Age, sea levels dropped hundreds of feet exposing the continental shelves. The planet's great rivers cascaded over the edges in great waterfalls. The rocky sill at Gibraltar kept the Atlantic waters out of the Mediterranean, and this sea began to dry up. Farther to the east, the Black Sea was now cut off from the Mediterranean's salty water by the silt-choked Bosporus, that narrow strait separating Asia Minor from Europe. In consequence, the Black Sea became a vast fresh-water lake fed by Europe's rivers to the north. The Ice Age eventually waned, and the oceans and Mediterranean began to rise. About 7,000 years ago, the hydraulic pressure on the Bosporus silt plug became too great and it popped. Salty Mediterranean water poured into lowlands around the Black Sea. Scientists estimate that 50 cubic kilometers of water surged through the Bosporus each -- 200 Niagaras in one colossal waterfall.

This portion is densely cratered from a period pf heavy meteorite bombardment. It is also carved by many channels that are thought to have been cut in ancient times by flowing water, water which quickly escaped into space or combined chemically with Martian minerals. The present atmosphere of Mars, in consequence, contains little water vapor. But some of the Martian landscape, notably Alba Patera, raises questions about the above scenario. The anomalous characteristic of Alba Patera is its relative smoothness and scarcity of impact craters. This Martian real estate is believed to be 2 billion years younger than the rest of the planet. Even so, it, too, is marked by "fluvial" features that resemble stream beds. Question #1 . How did Alba Patera get smoothed out or "reworked"? In other words, what happened to the ancient craters that must have pocked its surface, as they do everywhere else? Question #2 . Where did the water come from to cut Alba Patera's stream beds if all of the Martian water disappeared 2 billion years earlier?

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.

This methane is apparently not related to any oil or gas wells in the region.

In last winter's first hard frost, I found an odd ice formation in the bowl. Although the weather the previous day had been clement and the water was fluid, we had that night a sharp frost down to about -4 C. The following morning I noticed what appeared to be something sticking up out of the frozen water in the dish. On closer examination, it proved to be a solid 'spike' of ice, ending in an arrowhead. The ice was solid and came out of the side of the frozen water at an angle of about 45 . It was about 9 inches long and solid throughout." (Turner, Judy; "Spooky Spike," New Scientist, p. 54, November 2, 1991.) Two weeks later, the same journal published two radically different explanations of the ice spike. G. Lewis called the spike an "ice fountain" and stated that it is due to the well-known expansion of water as it freezes. R. Blumen-feld, on the other hand, attributed the growth of the spike to the fact that water molecules on the surface and in surrounding air are electrical dipoles. ...

Although its shoreline in complex, there is a deep channel about 2 kilometers wide with steep sides running lengthwise along the lake floor. When wind blows across the lake's surface, wind-drag pushes surface water downwind. When the wind stops or changes direction, the piled-up water is freed, and standing waves are set up as the water sloshes back and forth in the lake basin. These waves are called "seiches." Lakes usually have characteristic periods of oscillation. For Lake Champlain, it is 4 hours, with amplitudes measured only in centimeters on the surface of the water. What makes Lake Champlain of more than usual interest is the presence of a second seiche, an internal phenomenon not visible on the surface. In the summer, Lake Champlain is stratified with a thermocline separating a layer of warm surface water from much colder deep water. You can only "see" the thermocline if you lower a thermometer into the water. This thermocline also exhibits seiches, but they are startlingly different from those on the surface. In Lake Champlain, the period of the internal seiche is 4 days rather than 4 hours. The amplitudes fall between 20 and 40 meters instead of being in the centimeter range. Just a few meters ...

A famous example of the latter seichedriving force occurred on March 27, 1964, when the Great Alaskan Earthquake sent seismic waves rippling around the globe. Fourteen minutes after this quake, the tremors reached the U.S .

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.

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.

Hansen sent the accompanying mosaic of Landsat photographs of northwestern Nebraska. On this, the famous Nebraska sandhills appear like giant ripples. The width of the mosaic is about 340 kilometers, so you can appreciate the scale of the hills themselves. The crest-to-crest distances seem to be 2-3 kilometers. Roughly 35,000 square kilometers are covered with a sheet of sand that averages 8 meters thick. Mainstream geologists write these sandhills off as eolian (wind-carried) deposits laid down during the late Pleistocene. Hansen, however, along with geological iconoclast A. Kelly, demur. The Nebraska sanhills, they aver, were actually deposited by a wall of water sweeping down across the continent from the north -- very likely the consequence of an impact of a large asteroid.

Well, this phenomenon is hardly new and has a good explanation. We quote from a book first published in 1925. Here, a grape and soda water are employed: "A grape is not wetted by water, and so when it is put into the tumbler it sinks to the bottom of the soda water, where it collects bubbles at a great rate. Soon it is covered over with a sheet of bubbles that look like seed-pearls, and these bring it by their buoyancy to the surface. The grape is not much heavier than the water, and does not require much to lift it. At the surface the grape parts with some of its bubbles, which burst into the open air, and this goes on until it sinks again, only to collect a few more bubbles and once more be made buoyant. The process will repeat itself continually for many minutes until the soda water is 'dead.'" (Bragg, William; On the Nature of Things , p. 109, Garden City, 1950. Cr. A.

The water is cold and clear, an indication that this is not a geyser like Old Faithful; such geysers, of volcanic origin, send forth hot water. Through the years various observers have timed the flows at anywhere from four to twentyfive minutes, with similarly varying dry spells.

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.

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.

But as a precaution, Stuart Finlay, the seasoned 42-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.

From a dayglow experiment aboard NASA's satellite DE-1 (Dynamic Explorer-1 ) comes an unexpected discovery of considerable potential importance. Looking down on the earth, the DE-1 records the light emitted by atmospheric oxygen at altitudes of about 200-300 kilometers -- this is the so-called "dayglow." The experimenters, L. Frank, J. Sigwarth, and J. Craven, all at the University of Iowa in Iowa City, have found that their dayglow images are speckled with transitory dark spots. "According to Sigwarth, each hole expands like a drop of dye spreading out in a glass of water; within about 30 seconds the dayglow intensity drops by about 95 percent over an area of about 3,000 square kilometers. Then, over the next 3.5 minutes, the dayglow intensity increases toward its normal value as the hole grows to an area of about 25,000 km2 ." The Iowa group thinks that the holes or spots are created by meteors hitting the upper atmosphere because the spots follow the same time distribution as meteors. For example, they are more frequent during the well-known meteor showers. The theory is that the dark spots are formed when ice associated with the meteors is turned into water vapor, which reacts with the atmospheric oxygen producing the dayglow, in effect removing temporarily part of the light source. So far, everything seems relatively nonanomalous. ...

Everywhere in this part of Washington are deeply incised grooves and dry cataracts separated by water-streamlined bars. Exactly this sort of harsh, scoured topography can be found at Kasei Valles, Mars.

On the basis of a stereomodel of Viking images, we have measured the geometry of a steep, constricted reach of the north channel that drops 900 m in only 100 km. A late-stage flood is hypothesized to have scoured the channel. If we assume that channel striations indicate water levels, then the flood had a minimum cross-sectional area of 3.12 x 107 m2 (the putative flood had a width of 83 km, an average depth of 373 m, and a maximum depth of 1280 m).

Geologists custom-arily explain drumlins as debris piled up and sculpted by the ice sheets them-selves, despite the fact they look like they might have been shaped by flowing water. As we all know, the word "flood" is an anathema in geology, probably because a provable episode of extensive flooding would lend credence to the Biblical Flood! (Actually, many cultures around the world have similar flood legends.) Canadian geologist J. Shaw is now trying to break out of this philosophical prison. "According to Shaw, heat from the Earth formed huge lakes of meltwater that remained trapped beneath the North American ice sheet. As the sheet began to retreat near the end of the glacial age, the water broke through and flowed in torrents down to the Gulf of Mexico and Atlantic Ocean. While flowing under the ice cap, water would have surged in vast, turbulent sheets that sculpted and scoured drumlins. Each flood lasted until the weight of the ice cap once again shut off the outlet of the covered lake, Shaw says."

The water suddenly receded leaving Neeah Bay perfectly dry. It was four days reaching the lowest ebb, and then rose again without any waves or breakers, till it had submerged the Cape, and in fact the whole country, excepting the tops of the mountains at Clyoquot. The water on its rise became very warm, and as it came up to the houses, those who had canoes put their effects into them, and floated off with the current, which set very strongly to the north.'"

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.

They had learned that piles of porous rocks could, in desert climes, capture and condense surprisingly large quantities of water. Take, for example, the 13 pyramids of loose limestone rocks that the Greeks constructed some 2500 years ago at Theodosia in the Crimea: "The pyramids averaged nearly 40 feet high and were placed on hills around the city. As wind moved air through the heaps of stone, the day's cycle of rising and falling temperatures caused moisture to condense, run down, and feed a network of clay pipes. "One archaeologist calculated a water flow of 14,400 gallons per pyramid per day, based on the size of the clay pipes leading from each device." Weren't the ancient Greeks clever? But perhaps they had observed how some mice in the Sahara pile small heaps of rocks in front of their burrows and lick the condensed moisture off in the morning. Possibly we should have classified this item under "Biology"! (Dietrich, Bill; "Water from Stones: Greeks Found a Way," Arizona Republic , p. AA1, December 22, 1991. Cr. T.W . Colvin.)

These oscillations of the water surface are termed "seiches." Two fundamentally different kinds of seiches have been noted in the recent literature. The first variety is transitory and can be set into motion by weather disturbances and earthquakes. The second is permanent and a bit more mysterious. Let's take transitory seiches first September 17, 1992. Anglesey, England. At about 0700 in the morning: "I was on the beach at Trearddur on western Anglesey, when an acquaintance drove down the beach towing a fishing boat. He launched the boat in about six inches of water and we then engaged in conversation for a couple of minutes. Turning to the boat, we were amazed to find that it was high and dry about 20 metres from the water's edge. Small flatfish, mainly immature brill, could be seen stranded and flapping in the wet sand. About a minute later, the sea started to return and quickly rose up the beach beyond where the boat had originally been launched. An hour later, the oscillation in sea level was still taking place. I determined that the period was just over three minutes and the amplitude just under one metre, the latter measured with reference to a half-submerged ...

Nowata, Oklahoma. On this date, residents of the Nowata area heard and felt an explosion. Its source was unknown until W. Mitchell checked to find out why Double Creek had backed up. He found a scene of curious devastation, which was then linked to the earlier explosion. "The explosion blasted up large shale rocks, some estimated to weigh more than a ton, and filled about 150 feet of creekbed with shattered stone. Trees were blown down and the creek was partly blocked. "The water level upstream from the site is 3 to 4 feet higher than below, although water is flowing under the rocks. .. .. . "' It looks like a giant mole went all under the ground,' Mitchell said, .. .' There is no telling how big a hole is under there. You can hear water falling. Gas was bubbling up all along the bank. In one place the water was shooting up a couple of feet yesterday, like a fountain, but it has gone down now.' "Large pieces of shale landed 20 to 30 feet from the creek bank, mud was blown outward from the explosion and pieces of shale as large as a big tennis shoe were found as much as 200 feet from the creek."

... Project Sourcebook Subjects One of the most astonishing discoveries of modern science!We take this title from P. Huyghe's recent overview of the "oceans from space" controversy, printed not surprisingly in Oceans . (See p.000.) As readers will recall, we have been following this debate for over two years. 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. (Huyghe, Patrick; "Oceans from Space -- New Evidence," Oceans , 21:9 , April 1988.) Item 5. has been reported in other publications: "Using a telescope with a moving field of view -- a difficult technique that required a year of preliminary calculations to plan -- physicist Clayne Yeates has found and photographed what seems to ...

No. 79: Jan-Feb 1992 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Mercury's polar caps and icy minicomets Mercury, closest planet to the sun, should be baked bone dry, seeing that equatorial temperatures reach 800 F. 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 ...

... Science Frontiers ONLINE No. 97: Jan-Feb 1995 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects A Major Study Of Dowsing Most evidence for the efficacy of dow-sing is anecdotal. Most evidence for the inefficacy of dowsing comes from carefully controlled field experiments, including such props as buried pipes with and without running water and other juicy targets for the dowser's wand. It is, therefore, somewhat surprising to find that a large study by physicists at the University of Munich supports the reality of dowsing. Here follows part of the abstract from a paper on this work: "We report on the first major scientific program to tackle this intricate problem aiming for, at least, solid proof for either existence or non-existence of the debated phenomenon. Within a period of two years some 100 dowsers have been tested by means of sophisticated experiments, designed and supervised by a very large team of scientists. A statistical analysis of the results revealed a very high level of significance for the existence of a real dowsing phenomenon. "Further geological experiments have been conducted, and are still going on, which aim at the location of underground drinking water. The results turn out to be extremely positive. This leaves hardly any doubt that certain persons are capable of locating position-dependent anomalies by utilizing a new, still unknown mechanism. Various attempts will be described which explain how the reproducible phenomena could be dealt with. In particular, arguments will be discussed which speak in favor of the dominance of a cause-reaction model ...
