the increasing world demand for fish cannot be met by capture fisheries. aquaculture production is increasing and nowadays cage culture has an important role in meeting the world’s fish demand. the design of the physical structure of a cage is determined by the oceanographic conditions of the culture site. each design is site-specific and knowledge of the topography, wind force and direction, p...

Observations of internal solitary waves (ISWs) were obtained on a continental shelf during the Coastal Mixing and Optics (CMO) experiment. High-frequency, high-energy bursts were seen in north-component current data and temperature data, as well as in chlorophyll a concentration and beam c data. ISWs resulted in vertical pumping of biogenic and non-biogenic material, as observed in the optical ...

Occurrence and features of parametric roll (PR) on a weather-vaning floating production storage and offloading (FPSO) platform with a turret single-point mooring-line system are examined. The main focus is on the relevance of motions coupling and nonlinear effects on this phenomenon and on more general unstable conditions as well as on the occurrence and severity of water on deck. This work was...

The Offshore Aquaculture Consortium (OAC) was created as a collaborative, Gulf-wide, interdisciplinary research and development program in response to the U.S. Department of Commerce Aquaculture Policy. OAC research has demonstrated numerous components of offshore aquaculture in the Gulf of Mexico including permitting requirements, mooring systems, cage/mooring survival during several hurricane...

A bio-optical mooring, which was deployed for 240 days during 1987 in the western Sargasso Sea (-35øN, 70øW), provided among other things a detailed record of the seasonal distribution of chlorophyll a fluorescence and the scalar irradiance of photosynthetically available radiation. This data base was augmented by shipboard measurements of chlorophyll a concentration, chlorophyll a fluorescence...
