Science Frontiers ONLINE No. 50: Mar-Apr 1987 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Whales And Seafloor Pits Typical sizes, shapes, and disposition of whale-excavated pits in the Bering Sea. The focus of a 1987 paper in Scientific American, by C.H . Nelson and K.R . Johnson, is the northeastern Bering Sea, where sensitive side-scanning sonar has sketched large numbers of pits and furrows in the shallow sands. The pits range from 1-10 meters in length, 0.5 -7 meters in width, and 0.1 -0 .4 meters in depth. No known geological processes seem responsible. Farther east, in Nor-ton Sound, methane eruptions from buried ... matter do blow out circular craters; but the elongated pits investigated by Nelson and Johnson are gouged in sand considered too permeable for gas-crater formation. Rather surprisingly, the gray whale has become suspect as a pit excavator. They feed in the area of the pits; and the pits, before enlargement by currents, are just the size of the whales' mouths. The whales apparently dredge up sediment and, with their baleen, strain out amphipods (shrimp-like crustaceans) from the sand. The coexisting narrow furrows turn out to be the work of walruses digging for clams. (Nelson, C. Hans, and Johnson, Kirk R.; "Whales and Walruses as Tillers of the Sea Floor," Scientific American, 256:112, February 1987.) Comment ...

... field measurements and computer analysis link the gigantic ground drawings to the Andean tradition of dividing up space and time by cycles of the Milky Way. By including ethnoastronomy in the analysis, these conclusions differ from [those of] previous researchers. The first hypothesis tested was that the figures could be considered like labels to the lines. Of the twenty-seven figures, ten are birds, three are whales, and two are seaweed plants. Theodolite measurements revealed a non-random distribution of the directions of lines attached to look-alike figures. The second test showed a physical relationship of present-day Andean plant and animal figures imagined as silhouettes in dark spots along the Milky Way to figure-lines pointing to the rising and/or setting of the same Andean figure 2000 years ago. ... , 12:1 , Summer 1996.
