Continental shelf processes affecting the oceanography of the South Atlantic Bight. Progress report

Description: Results are reported from studies on the physical and dynamical processes controlling and affecting the distribution of phytoplankton nutrients on the continental shelf in the South Atlantic Bight off the coast of North Carolina, South Carolina, Georgia, and Florida. The initial objectives were to determine the short term, i.e., 2 to 10 days and longer term flux of nutrients onto the continental shelf. This is clearly related to the more general problem of combined physical and biogenic control… more

Hydrography of Onslow Bay, North Carolina: September 1975 (OBIS II)

Description: Data collected during studies of Onslow Bay, off the North Carolina coast during cruises during September, 1975, are reported. Current meters and thermography were placed at depths of 10 and 22 m along the 28 m isobath in the northeastern and southwestern sectors of the Bay. Data are included on wind turbulence and velocity; seawater salinity and temperature at various depths; the content of nitrates, phosphates, silicate, oxygen, chlorophyll, and phytoplankton biomass at various depths. Hydrog… more

Onslow Bay Intrusion Study Hydrographic Observations During Current Meter Servicing Cruises in August, October, and December 1975. ORBIS, I, III and IV. [Atlantic Coastal Waters Off Georgia]

Description: Data are presented from a preliminary analysis of chemical/physical data obtained during three current meter servicing cruises in Onslow Bay off the coast of Georgia, in August, October, and December 1975 aboard the R/V ADVANCE II. These cruises were made as part of an ERDA sponsored study investigating the shelf processes effecting the distribution of nutrients in the South Atlantic Bight. The objective of these cruises was to collect temperature and chemical data to correlate with the data re… more

Continental Shelf Processes Effecting the Oceanography of the South Atlantic Bight. Hydrography of Onslow Bay, North Carolina: September 1975 (OBIS II). Progress Report

Description: Over the course of OBIS II, 3-14 September, two intrusion cores were observed. One was apparently trapped nearshore over much of the study period, but as time went on, it either dissipated, moved too far shoreward or moved too far laterally along the shelf to be detected by the existing observational grid. The other (later) intrusion was first detected on 5-7 September and was observed to be moving into the Bay from the southeast over the remainder of the study period. Plots of the horizontal t… more

Mathematical model of nutrient distribution in coastal waters

Description: An approach to biological modelling involving the use of separation transformation theory has been developed. By use of the theory, it is possible to reduce the number of independent variables in the system. The original four dimensional system (x, y, z, t) can be reduced to a vertical plane conceptual model by assuming along isobath homogeneity in the flow field as a partial function of the baroclinic flow field. Both temporally dependent and independent nitrate concentration equations are the… more

Onslow Bay physical/dynamical experiments, Summer--Fall, 1975. Data report. [Continental shelf processes affecting the oceanography of the South Atlantic Bight]

Description: The objectives of this data report are to provide a commentary on the logistics and methodology of, and also to serve as a documentation of, the experimental and observational data sets obtained during the summer and fall and winter of 1975. Beyond the inclusion of the reduced, i.e., computer processed and filtered, data, no interpretation is provided. It is anticipated that this report will serve as an effective guidebook for future field programs. This report includes data from four cruises (… more
