This paper will review the development of marine oriented RF systems, examine the current state-of-the-art technology, and try to predict the direction of future electromagnetic-marine systems.","PeriodicalId":437366,"journal":{"name":"OCEANS '85 - Ocean Engineering and the Environment","volume":"102 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":"133617103","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 paper outlines major U.S. policy areas and the Arctic programs of DOE and other U.S. agencies which are pursuing Arctic energy issues. Arctic energy development opportunities, particularly in the context of supportive research and cooperative efforts, are also discussed.

Studies in the Atlantic OCS Region have since made contributions to the body of knowledge concerning oceanographic processes of OCS environments extending from Nova Scotia to Cape Canaveral. The Atlantic Studies Program has contributed not only to the characterization of these areas and impact assessment on OCS resources but also to the advancement of oceanographic technologies and deepwater research. The program is committed to wide dissemination of information available in the form of data bases, reports, maps, models, and refereed publications. This overview focuses on the extent and principal results of studies which may prove valuable to resource managers and scientists investigating OCS processes.","PeriodicalId":437366,"journal":{"name":"OCEANS '85 - Ocean Engineering and the Environment","volume":"196 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":"114867623","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}

To satisfy this responsibility, NOS maintains a network of 225 permanent tidal and water level measurement stations throughout the United States and its territories. This network is called the National Water Level Observation Network (NWLON). Because the equipment and technology used to support the NWLON is aging and obsolete, NOS is in the process of replacing it with the Next Generation Water Level Measurement System (NGWLMS). A Program Development Plan (PDP) has been approved and implemented; and this paper describes the Technical Development Plan (TDP) which will be used to bring the total system through its development phases. The NGWLMS is a fully integrated system encompassing new technology sensors and recording equipment, multiple state-of-the-art data transmission options and integrated data processing, analyses, and dissemination subsystems.This paper describes the background to the TDP and the procedures, responsibilities, policies, technical aspects, and schedules necessary to develop, test, acquire, and deploy the NGWLMS plus an additional 150 supplemental stations. The technical aspects delineated include those activities necessary to move the NGWLMS Program from the concept evaluation stage through production and deployment to full operational status, i.e., the provision of services to users. The topics addressed include program management and planning, functional subsystem descriptions, interdependencies and requirements of other systems and programs, reliability and maintainability, integrated logistic support, test and evaluation, personnel training, and deployment procedures. Multiple uses for NGWLMS data, system requirements, and operational constraints are also discussed.","PeriodicalId":437366,"journal":{"name":"OCEANS '85 - Ocean Engineering and the Environment","volume":"1 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":"129531624","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}

Here we will report on two examples of the use of remote sensing in ocean measurements: 1. The use of high resolution ocean images of swell to determine wavelength and direction of the dominant waves as well as to detect and measure surface currents and horizontal shears. 2. The use of infra red ocean imagery to determine water velocities and circulation patterns.

Real-time measurements can: (1) provide immediate oceanographic information to the user; (2) form the basis for more accurate forecasts; and (3) drive numerical hydrodynamic models to provide even broader marine information services. For the commercial shipping industry, real-time model systems represent an important step beyond reliance on classical tide predictions; making maximum use of available channel depths leads to safer and more economical commerce. Real-time/ forecast circulation will make navigation safer at key locations, and will increase the success of search and rescue operations and the clean-up of oil spills and other hazardous materials. Real-time dynamical model forecasting itself represents an important interpretative physical tool which can increase our understanding of the geophysical phenomena that affect the maritime community everyday. Uses for sophisticated real-time model systems, like uses for satellite imagery, will continue to develop.","PeriodicalId":437366,"journal":{"name":"OCEANS '85 - Ocean Engineering and the Environment","volume":"11 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":"117137416","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}
