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.
