The apparatus drops warm salt water entrained with air down a penstock to drive a hydroelectric turbine generator. The salt water is cooled by the ocean sump and becomes heavier than the ambient water. The air is compressed hydraulically and separated to create a second work force. The forces, together with salinity, work to exhaust the water. The invention consumes no fossil fuel, does not pollute, and has the potential to furnish most of the world's electric needs without subjecting people to radiation. The US Department of Energy (DOE) has estimated that a mechanism of 2 MWe can be built at a cost of $7200/kWe. Using the same cost basis, a 2-MWe hydro well could be built for $1345/kWe because it is only 1/3 as deep and handles 1/8 the amount of water of conventional OTEC devices.<<ETX>>","PeriodicalId":435174,"journal":{"name":"OCEANS '88.

The variations of the radar return waveform shape and signal level are correlated with the variation of the ice type determined from photography. The AAFE altimeter has demonstrated that the return waveform shape and signal level of an airborne pulse-limited altimeter at 13.9 GHz respond to sea ice type. The signal level responded dramatically to even a very small fracture in the ice as long as it occurred directly at the altimeter nadir point. Shear zones and regions of significant compression ridging consistently produced low signal levels. The return waveforms frequently evidenced the characteristics of both specular and diffuse scattering.<<ETX>>","PeriodicalId":435174,"journal":{"name":"OCEANS '88.

The Beaufort Sea is eroding the Alaska coastline at an average rate of almost 3 meters per year, and offshore islands are migrating shoreward at an even more rapid rate. The Federallstate offshore-leasing boundary follows the retreating coastline shoreward. In addition, various interpretations of laws and court decisions allow several different versions of the boundary to be drawn from the same data. Cooperative shoreline surveys are conducted by the State and Federal Governments resulting in major mapping projects utilizing a series of tide stations, survey control, and aerial photography. The resulting data are being used to establish boundaries, update nautical charts, and provide information for scientific studies.","PeriodicalId":435174,"journal":{"name":"OCEANS '88.

The current Naval assessment of TBT paints is presented in terms of economic, environmental, and health and safety issues. a1 ternate ablative paints tested have given mixed results , but acceptable economic and environmental results. directions are discussed. The Future antifouling paint needs and UNITED STATES' NAVAL EXPERIENCE WITH ADVANCED ANTIFOULING PAINTS Extended drydocking intervals and foul-free service of up to 7 years became a reality for the marine industry with the introduction of ablative organotin antifouling paints. These coatings resulted in reduced propulsion fuel costs up to 16 percent, completely eliminated the expense of underwater scrubbing, and halted the ensuing damage suffered by the paint from the mechanical process which further increased the savings. is an outstanding achievement because, at 20 knots, a fouled ship may require 19 percent more horsepower to maintain its speed. The ablative organotin copolymer paints replaced the old conventional cuprous oxide paints, which are good for only 18 to 24 months, and are no longer able to meet the increasing demands of the commercial marine industry and combat naval forces. Ablative copolymer-type organotin paints were first introduced in Europe in 1974 on commercial ships. By 1978, the news of its superior performance had become well-publicized in the United States, and led to the application, in February 1979, on a U. S . Coast Guard cutter. This ship performed foul-free for the next 7 years. At the interim dockings in 1980, 1983, the ship was water washed to remove the slime mechanically damaged areas were touched up, and the ship was returned to the water. The coating continued to perform well until 1986. This from June 1981 to September 1987. In both cases, the ships did not require any underwater brushing in the 6 years that the organotin was on the hull. Other examples of outstanding long service, where organotin is still performing, are a submarine painted in 1982, and an aircraft carrier painted in 1984. combatants and auxiliary ships up to the end of 1985, just before the ban went into effect, and these ships are continuing to perform well.
