Data include significant wave height, average wave period, wave spectra, and water temperature. The two systems were found to provide comparable estimates of wave height, wave period, and wave spectra only during periods when significant wave height exceeded 0.5 m. At lower wave heights, the NOMAD buoy gave slightly lower estimates of significant wave height than the Waverider. The Waverider processing system was unable to provide accurate spectral information for low wave heights because of aliasing. Water temperature measurements from the two systems were virtually identical.","PeriodicalId":437366,"journal":{"name":"OCEANS '85 - Ocean Engineering and the Environment","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126858232","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The program will produce base maps to support the exploration, exploitation, conservation and management of natural resources in this vast area which is now under national sovereignty. This is a cooperative effort with the United States Geological Survey and a part of a Federal program in support of the Exclusive Economic Zone. The primary mission of the program is to produce accurate, high resolution bathymetric data using modern multibeam swath mapping systems. NDAA is currently applying its two systems - a Sea Beam and a Bathymetric Swath Survey System (BS3)- to this task. Additional systems are to be installed. Characteristics of these systems and the positioning equipment being used as well as the data processing techniques being employed will be examined and related to the data products which are being prepared. Mapping progress to date will be reviewed and survey plans described. Opportunities for acquisition of other data in conjuction with the planned surveys will be presented.","PeriodicalId":437366,"journal":{"name":"OCEANS '85 - Ocean Engineering and the Environment","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123191367","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Major specifications of the present day prototype in terms of salinity are: Accuracy:pm 0.005precision:pm0.001, reasonable resolution: 0.0003. The range of measurements covers S = 0...40. A favourable feature is the inherent possibility of measurement in continuous flow. Problems of thermostating and handling of the liquid samples have been solved. Research and development is going on with emphasis on increasing the handling speed of samples. This focusses on the design of a very unconventional optical double- cuvette which allows for high speed flushing. While at OCEANS'84 the description of the foundations of the measuring principle stood in the foreground, critical data from performance tests are now to be reported on and discussed in detail.","PeriodicalId":437366,"journal":{"name":"OCEANS '85 - Ocean Engineering and the Environment","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121203217","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The winch incorporates a novel arrangement of a grooveless traction roller system to allow mooring line storage at a low tension and provides for automatic separation of successive cable wraps on the rollers to eliminate snagging of terminations. An angled roller mounting arrangement allows a \"pack\" of cable wraps to glide back and forth across the rollers, following the spooling on the storage reel without the aid of a fairlead system. Storage reels are quickly interchangeable with hydraulic power assist for the separation of different mooring line types or the laying of very long moorings. The device has been employed for the successful deployment and recovery of 5000 m (16,000 ft) long steel/Kevlar moorings and has significantly reduced handling problems.","PeriodicalId":437366,"journal":{"name":"OCEANS '85 - Ocean Engineering and the Environment","volume":"259 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114300004","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The current Administration has emphasized the necessity of fostering strong private industry/government partnerships. In doing this, the government should provide basic research, but private industry must put it to work. NOS is fulfilling its mandate of providing basic oceanographic research and has established partnerships with industry in order to develop cooperative projects that are mutually beneficial and effect technology transfer. Through activities such as the NOAA Users' Conference and regional Project PORTS workshops, private industry has learned of NOS's services and NOS has increased its awareness of the oceanographic industry's needs. In order for NOS to continue to meet those needs, more attention must be focused on the importance and usefulness of applied oceanographic products.

The two major elements of the program are: (a) A Nasa Scatterometer NSCAT to measure winds from space to be flown on the Navy's Remote Ocean Sensing System NROSS satellite; and (b) the Topex/Poseidon altimetric satellite to measure currents and tides. The NSCAT will measure surface wind speed and direction on a 50 km grid with an accuracy ofpm 2m/s andpm 20degalong 600 km wide swaths on either side of the spacecraft to provide near global coverage every two clays for three years. NSCAT is funded and launch is planned for September 1990. The combination of Nasa's Topex program with the Poseidon program of the French Centre National d'Etudes Spatiales, Topex/Poseidon, has led to plans to launch a joint altimetric satellite in February 1991 to measure sea-surface topography with an accuracy ofpm 14cm and a precision ofpm 2.4cm along a fixed global grid every 10 days for three years.

The fully operational TM sensor onboard Landsat V which was placed in orbit late in 1984 has proved particularly useful for coastal landcover applications. This paper reports on an analysis of Nantucket Island, Massachusetts. The fine resolution (1/4 acre) and the addition of three electromagnetic bands greatly enhances the interpretive capabilities of the Landsat system, especially in the shallow nearshore marine environment. Nantucket Island is the last remnant of a terminal moraine, whose southern and western shores have been eroding since the end of the Pleistocene period. With a projected increase in sea level, these processes are likely to continue, perhaps even increase. Sand, silt and gravel are constantly being transported, trapped, reworked and redeposited by some of the strongest tidal currents in North America. This results in constantly changing banks, reefs, spits and barriers. The fine resolution and the frequency of orbital overpass make scenes from Landsat's TM sensor a particularly valuable coastal surveillance tool.","PeriodicalId":437366,"journal":{"name":"OCEANS '85 - Ocean Engineering and the Environment","volume":"119 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124712913","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
