Abstract In the Gulf of Mexico, the distinction between natural and artificial resources has become obscure. Over one quarter of the hard substrate existing offshore has been created by the steel legs of nearly 4,000 petroleum platforms. The encrusting organisms and reef fish communities established ...
Abstract Industrial class vessels (offshore supply boats, tugs, and fishing vessels) have experienced stability problems during the last two decades. Many of these vessels are of similar hull form, including hard chins, a shallow-depth transom stern and large beam/length ratios. Existing stability criteria ...
ABSTRACT This paper presents a review in narrative form of the various main elements of submarine telephone cable repair work at sea. Generally well known techniques are mentioned only in passing; specific techniques peculiar to cable work are described more fully, but with no mathematical treatment. ...
ABSTRACT There is a need to continue geophysical research for petroleum exploration and exploitation, and for basic understanding of marine geology, and for assessment of energy and minerals resources. There is also a need to conduct that research compatibly with our marine environment. Modern marine ...
ABSTRACT Louisiana's offshore oil and gas industry began in 1947 when the first well was drilled out of sight of land south of Terrebonne Parish, Louisiana. Today, over 3,837 offshore oil and gas platforms have been installed, supplying 25% of the United States' production of natural gas and approximately ...
ABSTRACT The world's fisheries resources have been under increasing pressure from a greatly expanded harvesting capacity. The common property aspect of the fisheries resources, coupled with the lack of effective management regimes, has resulted in the depletion of a number of valuable fish stocks. ...
ABSTRACT A 22-month investigation is being conducted cooperatively by private fishing industry and the U. S. Government to demonstrate the feasibility of using satellite (LANDSAT) data for enhancing the management and utilization of coastal fishery resources in the northern Gulf of Mexico. Menhaden ...
ABSTRACT This paper reviews the statistics of ""Spotting Fluids"" to free stuck drill pipe as well as the economics and statistics of drill string fishing operations. Data were taken from Mobil Oil Exploration and Producing Southeast Inc.'s (MOEPSI) records from 1970-1981. Only' those events-which occur ...
ABSTRACT This paper examines sport and commercial fish catch in the Santa Barbara Channel over a 20 year period to attempt to detect possible changes in catch that might be associated with OCS activity in the area during that same period. Such changes were not found, indicating that the effects of ...
INTRODUCTION The world catch of fish has increased steadily since World War II from 19.6 million metric tons in 1948 to 69.3 million metric tons.1 Although the ultimate sustainable world catch has been predicted to be two to three times this level,2 the increase in over-all catch, and particularly ...
Abstract Direct and indirect benefits which may be derived from marine environmental prediction are examined in both quantitative and qualitative terms for the eastern Gulf of Mexico area. Conclusions drawn include the following: Of the primary environmental factors affecting the dimensions and types ...
INTRODUCTION The study of how fish behave in relation to fishing gear has become increasingly important. The Danish Fisheries Technology Institute (DFTI) is engaged in a major research project on this theme, with particular emphasis on video observation of fish in relation to cod ends, including the ...
ABSTRACT This paper presents the results of a limited feasibility study for the New England Groundfish Trawling Industry and describes the present situation and problems of that industry, the systems considered and the development of the computer program for the systems. It also gives design information, ...
Background Using treated wastewater in agriculture irrigation could be a realistic solution for the shortage of fresh water in Iran, however, it is associated with environmental and health threats; therefore, effluent quality assessment is quite necessary before use. The present study aimed to evaluate ...
Background Acute viral necrosis virus (AVNV) is the causative agent of a serious disease resulting in high mortality in cultured Chinese scallops, Chlamys farreri. We have sequenced and analyzed the complete genome of AVNV. Results The AVNV genome is a linear, double-stranded DNA molecule of 210,993 bp ...
The Bohai Sea is a large semi-enclosed shallow water basin, which receives extensive river discharges of various terrestrial and anthropogenic materials such as sediments, nutrients and contaminants. How these terrigenous inputs may influence the diversity, community structure, biogeographical distribution, ...
Abstract Description of the Proposed Paper This paper will review the regulations pertaining to offshore biocide use in different regions of the world. The roles of regional and global organizations in helping to harmonize available environmental, health, and safety information will also be discussed. Application Many ...
Abstract The Gulf of Mexico incident has led to the revision of operational safety and response strategies by the oil industry. Even countries with long tradition in E&P activity, as Norway and the United Kingdom, established working groups aiming the revision of their operational safety and response ...
Abstract Ocean thermal energy conversion (OTEC) is a baseload renewable energy source particularly suited for tropical zones. It uses the temperature difference between the warm surface ocean water and the cold deep ocean water to generate electricity and, if desired, potable water. This alternate energy ...
Abstract This paper reviews the whole round of technology used underwater and looks to the future direction each of the technologies is going. It also seeks to bring out areas where these technologies can cross-fertilize and where diversification of the skill sets developed can be used elsewhere. Examples ...
