... to any known triggering force. The frequency of occurrence of these "coastal seiches" may be a clue to their source. For example, off the Puerto Rican island of Magueyes, coastal seiches are most common about 7 days after new and full moons, suggesting a tidal influence. Oceanographers G.S . Giese and R.B . Hollander think that these coastal seiches are the consequence of internal waves (solitons*) formed at the southeastern edge of the Caribbean where tidal effects are particularly powerful 2 days after new and full moons. These slowmoving internal waves take 5 days to reach Puerto Rico, where they emerge as coastal seiches. Similar internal waves created by tidal currents at the edges of the continental shelves and deepwater sills may explain the mysterious coastal seiches recorded in the Anadaman and ...

A seiche (pronounced "saysh") is a rhythmic rocking motion of a body of water that has been disturbed by natural forces, such as sudden weather changes and, especially, earthquakes. 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 . Gulf coast and triggered numerous seiches in bays, harbors ...

Since the wave was solitary and four times the height of the gentle swells, it is unlikely that it was a chance combination of the swells. Most likely it was a surface manifestation of an internal wave that had been reflected from an undersea obstacle like the continental shelf.

... sea oscillation in the accompanying graph. Recent studies of the Puerto Princesa seiches show that the amplitudes of the seiches are greatest every two weeks, indicating they are tied to the astronomical tides. However, they lag the lunar tide by a couple of days. Geophysicists now look to Pearl Bank in the Sulu Sea, some 450 kilometers southeast of Puerto Princesa, where they believe tidal currents create "internal waves" as they hit the shallow bank. These internal waves travel beneath the surface at speeds of only about 8 kilometers/hour, taking about 2 days to reach Puerto Princesa. Here, they surge against the land, causing the observed seiches. (Giese, Graham S., and Chapman, David C.; "Coastal Seiches," Oceanus , 36:38, Spring ...

These oscillations of the water surface are termed "seiches." Two fundamentally different kinds of seiches have been noted in the recent literature.

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.

... 'We made loops in our course', Nansen wrote, 'turned sometimes right around, tried all sorts of antics to get clear of it, but to very little purpose.'" Nansen asked the noted physicist and meteorologist V. Bjerknes to look into the frustrating phenomenon. Bjerknes found that the energy of the ship's propeller was, in essence, being siphoned off to create internal waves along the interface between the light fresh water and dense ocean water underneath rather than propelling the ship forward. (Walker, J.M .; "Farthest North, Dead Water and the Ekman Spiral," Weather, 46:158, 1991.) Reference. Dead water and "slippery seas" are cataloged in GHC5 in: Earthquakes, Tides. This book is described here ... 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 ...

... , evolution would have been remiss if it had not tried to evolve "Carnot creatures." For, as D. Jones comments below, Carnot creatures would be adaptable to many more habitats in the universe than photosynthetic creatures, which must have a sun with a very specific electromagnetic spectrum. "Many worlds, from distant 'brown dwarf' stars to the satellites of giant planets, may have internal heating but no effective 'Sun'. If Carnot life is possible, it may well have evolved in such dark and distant places -- making life abundant throughout the Universe. Indeed, our distant descendants may be able to harness Carnot biochemistry to sustain themselves on geothermal or residual browndwarf warmth when the Sun finally grows dim." (Jones, David; "The Dark Is Light Enough ... " Nature, 385:301, 1997.) Comments. To our knowledge, those who search for extraterrestrial life do not consider the possibility of Carnot creatures and wouldn't recognize them if they stumbled across them or their signals. For example, Carnot creatures might emit infrared signals rather than radio waves; and they might be immense in size. (See related item under ASTRONOMY in this issue.)
