Title: Continental shelf processes affecting the oceanography of the South Atlantic Bight: Progress report, June 1, 1987 to May 31, 1988. [FLEX]

Abstract

This study of continental shelf processes affecting the oceanography of the South Atlantic Bight (SAB) is part of the interdisciplinary DOE-sponsored South Atlantic Bight Program. Our part of the program involves hydrographic and nutrient characteristics of the region. Current research efforts in the SAB Program are being focused on the inner shelf region where effects of bottom friction, local wind forcing, river and estuarine discharge, and tides, which are all small scale processes, are important. Our major accomplishment during the past year was the completion of the FLEX (Fall Experiment) field study. Since most of our data collection is computerized, preliminary hydrographic data analysis was done on board ship during the cruise and preliminary results are available. These results will be presented in this report. We are just beginning our standard data processing and data analysis procedures. We continued the processing and analysis of SPREX data collected during April 1985. Work has also continued on the older GABEX I and II data sets. 8 refs., 19 figs., 2 tabs.

  • As part of a study of continental shelf processes affecting the oceanography of the South Atlantic Bight, data collected during the Spring 1985 SPREX field experiment was processed and analyzed. The goals of the analyses were to: (1) determine the distribution of temperature, salinity, nutrients, and humic fluorescence such that flow fields and distributions of variables could be related to wind forcing events; (2) determine the time change in nutrient concentration and salinity at selected current meter locations; and (3) evaluate the usefulness of tritium as a fresh water tracer in the nearshore region of the South Atlantic Bight.

  • In the past year, we executed an extensive six week field effort, GABEX-II. Chemical analyses of samples have been completed and the large amount of physical data gathered has been reduced to a workable form. This report contains some of the first results. The GABEX-II measurements combined with other observations in the last and previous years continue to greatly increase our understanding of the South Atlantic Bight during the summer season, when the continental shelf is vertically stratified. Our field effort consisted of six cruises of five days duration in consecutive weeks to map the shelf with transhelf sections correspondingmore » to principal current meter sections. Also, the St. Augustine section was repeated twelve times at four day intervals and thus provided a cross shelf time series of the parameters measured.« less
  • GABEX II is a large scale observational effort involving three ships and a large array of current meter/temperature/pressure moorings. This particular contract was primarily responsible for the towed sensor /CTD/XBT/O/sub 2//nutrient measurements on the CAPE HENLOPEN, and the nutrient measurements from the other ships. The field effort consisted of six cruises of five days duration in consecutive weeks to map the shelf with transhelf sections corresponding to principal current meter sections. The observations are an excellent example of the summertime intrusion process in the South Atlantic Bight. Over the six week study period, at least two intrusion events occurred andmore » one middle shelf intrusion stranding was observed. It was demonstrated that significant amounts of nutrients are advected onto the shelf and assimilated.« less

  • This is a report on the progress of continental margin oceanographic studies being conducted as a part of the overall DOE South Atlantic Bight program. The NCSU-DOE program is working towards a fundamental understanding of oceanographic processes which determine the transport pathways, residence times and ultimate fate of biological and chemical parameters in the coastal environment. Additionally, the SAB has been considered a potential area for fuel producing facilities and activities, as a medium for fuel transport and as a fuel waste receptacle. In that regard, impact upon the environment and environmental impact upon the activity can only be addressedmore » with a more thorough assessment of the environment itself. Research activities have been directed toward the development of the bottom mounted tripod multiple input sensor system, toward the continuing analyses of South Atlantic Bight (Gabex I, Carolina Capes and Gabex II) current meter and ancillary data sets and toward the development of conceptual and theoretical models of continental margin processes and effects.« less
