The objective of the first study was to isolate the two components, corrosion and wear, in order to determine each of their influences on the corrosive-wear process on steels. The second study was designed to produce uniform wear on the steel's surface, providing more accurate data on the steel's wear resistance and to determine the effects of alloy additions. The steel presently being used for buoy chain, which is similar in composition to ASTM 1022 steel, was compared to ASTM 4140, 4340, 8740, and a heat-treatment 4140 steel in order to identify a material which would provide a longer life buoy chain. The results of the experiments showed that the wear component contributed material losses of one to two orders of magnitude greater than the corrosion process. It was also determined that the 4340 steel would be the most suitable material for longer life buoy chain. This alloy's high nickel content would reduce the potential for pitting attack, which can be extremely damaging to a mooring. The microstructure of the 4340, with a low ferrite to pearlite ratio and fine grain size, would provide an increased wear resistance of up to four times greater than the 1022 steel.

The capabilities and limitations of remote sensing should be better understood by policy and decision makers, as well as nonremote-sensing oceanographers. Satellites are perceived as being the solution to many nagging ocean surveillance problems, like pollution monitoring. While satellites hold the promise to do more in the future, and are critical elements of various maritime programs today, the applicability of space-based remote sensing should not be oversold. This year is the tenth anniversary of the TIROS-N series of polar-orbiting spacecraft. I t is time to reexamine what the nation's only operational remote sensing satellites have contributed to oceanography and commerce. When planned, these satellites were not expected to be beneficial as they now are or can be.","PeriodicalId":435174,"journal":{"name":"OCEANS '88. 'A Partnership of Marine Interests'.

Remote sensing studies of estuaries can be considered as being of two different types: estuarine intercomparisons (between estuaries) and intraestuarine (within estuary assessments). Current research has allowed initial efforts of estuarine intercomparisons of light attenuation and suspended sediments. Remote sensing can provide inputs to mathematical models used for research and management of estuaries and near coastal waters. The in situ optical profiling approach is transferable to other estuarine studies.<<ETX>>","PeriodicalId":435174,"journal":{"name":"OCEANS '88. 'A Partnership of Marine Interests'.

The backward bent duct buoy configuration, developed to solve this problem, is applicable to navigation aids including light buoys and light ships, telemetering buoys, military warning buoys, and other utility buoys. It can also be used for offshore station-keeping buoys, with or without moorings. By upscaling floating wave power generators are created that can supply power to both island and coastal communities. The energy cost of such systems is estimated to be about 38 yen/kWh for islands in the subtropic zone and about 15 yen/kWh in high-wave-power zones.<<ETX>>","PeriodicalId":435174,"journal":{"name":"OCEANS '88.

Acoustic data obtained from the first two deployments are of very high quality, with wider bandwidth and dynamic range than data sets acquired during earlier experiments using analog recording methods.<<ETX>>","PeriodicalId":435174,"journal":{"name":"OCEANS '88.
