A patented hydro-well invention is described that falls into the classification of an open-cycle ocean thermo energy conversion device. 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.<>

The Jet Propulsion Laboratory and the University of Alaska Geophysical Institute have initiated a program to receive, record, process, and archive synthetic-aperture radar and optical images at the Fairbanks campus. Data will be acquired from the European Space Agency E-ERS-1 and the National Space Development Agency of Japan J-ERS-1 spacecraft. The author focuses on the system which catalogs and archives signal data and derived data products, and provides an interactive product order function for users. A mission planning subsystem provides the capability to predict satellite swath coverage of the spacecraft, manages data acquisition requests, and produces an operations schedule for the receiving ground station and the SAR processing system.<>

Pulse-limited radar data taken March 1978 with the 13.9 GHz AAFE (Advanced Applications Flight Experiment) altimeter from 1500-m altitude over ice in the Beaufort Sea are registered to high-quality photography. 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.<>

Natural coastal processes and complicated legal questions present difficult resource-management problems for oil leasing in the Alaskan Arctic Ocean. 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.

The common analytical technique for butyltins involves extracting the species as halides, derivatizing to hydrides or tetraalkyltins, separating by using gas chromatography, and quantitating with flame photometry or atomic absorption spectrometry. To arrive at certified concentrations of butyltins in standard reference materials (SRMs), it is, however, imperative to have results from at least two independent analytical techniques.

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.

The U.S. Government continues to enjoy excellent partnerships within the National Oceanic and Atmospheric Administration (NoAA) I private industry, universities, the U.S. Navy, and other Government agencies in the collection of marine meteorological and oceanographic data from the world's oceans. A partnership exists where the maritime industries provide the platforms and personnel and NOAA and Navy provide training, equipment, and logistics support. Data gathered by this partnership and received at the National Prediction and Archive Centers aid the entire maritime industry by improving forecasts and services thus allowing ships to make safer voyages while saving time and money. This partnership is not limited to U.S. ships but extends to ships of other countries. This international cooperation makes possible the collection of ocean data on a global scale, allowing the world to better understand global environmental changes and their interactions with the oceans.
