The SEEP-I study of the Mid-Atlantic Bight (MAB) was completed and results will be published this summer in a special issue of Continental Shelf Research for which the principal investigator was guest editor and author of three manuscripts. Additional results of the work in the South Atlantic Bight (SAB) are discussed in a recent text published by Academic Press. To summarize the field component of the MAB study, i.e., the analysis of moored fluorometer records, the researchers found a significant export of chlorophyll from the shelf to the slope approx. = 0.30 g C m/sup -2/ day/sup -1/ during February to April 1984. Vertical fluxes at the shelf break were 0.10-0.16 g C m/sup -2/ day/sup -1/, suggesting that most of the organic matter in the deep slope waters originates from shelf-produced phytoplankton that is laterally injected near the bottom, rather than from sinking, slope-produced phytoplankton. Thus the shelf may be a significant source of deep slope organic matter in the Mid-Atlantic Bight. 7 refs., 1 fig.
