    In the near future, the U.S. will acquire-in the legal sense of property-1.4 billion acres of ocean space within an exclusive economic zone out to 200 miles offshore. In effect, the new area under national control will be an extension of the public lands which are retained under the stewardship of the federal government. This will create a need for the development of an ocean and coastal resource ... View full abstract»

    Problems peculiar to oceanographic measurements in polar regions are divided into those due to the need for specialised deployment systems under winter/spring conditions and those due to the oceanic environment. It is concluded that major difficulties arise due to the lack of commercially available systems designed for use from the sea ice surface and a lack of a properly integrated approach to a ...

    The 1970 decade witnessed the successful demonstration of two key technical developments required to exploit the deep ocean resource-manganese nodules. The questions "can the nodules be mined?" and "can the metals be removed?" have been answered in the affirmative. The critical path in present programs includes the minimum of six years required to obtain permits, etc. for siting a nodule processin... View full abstract»

    This is a scheme to utilize the low grade energy represented by the temperature difference between the deep and surface water of the oceans. If appropriate atmospheric and oceanic conditions pre- vail, this system can be used to condense fresh water directly from the atmosphere in quantities large enough to be used as a potable water source by coastal residents. Cold deep sea water is used as a he... View full abstract»

    Truncated expansions based upon the sampling theorem but containing only a few terms can be very useful for practical interpolations of band-limited or narrow-band random signals. The major goal of this work is to find and compare efficient and "statistically accurate" algorithms for the dynamic analysis of the ocean systems. The statistical accuracy of truncated sampling interpolations is investi... View full abstract»

    We suggest that the buoyancy forces on fresh water at the surface of the sea or immediately below the surface of the ice permit the use of this fresh water as an efficient means of transferring heat energy to the sea-ice, to melt it or to prevent its formation. The source of the necessary heat may be found in the lower levels of fresh water lakes, in waste heat from industrial processes or in the ... View full abstract»

    A need has been stated for oceanographic measurements made through the ice cover by an unmanned, microcomputer controlled air deployed system. A novel ice drilling concept has been identified to provide a highly efficient means of penetrating ice surfaces up to 15m thick with a 15cm diameter hole. In support of a computer program modeling the drilling process, a series of full scale tests were per... View full abstract»
