| Summary: | Accessory pigments were used to infer phytoplankton classes an anticyclonic Loop Current eddy that was present to the and coastal physical processes were investigated as part of associated with a local increase in chlorophyll in the middle bottom waters where a distinct chlorophyll maximum was found. chlorophyll maximum was associated with the nitracline on the class. Cyanobacteria, dinoflagellates and other small concentrations. On the middle shelf, benthic regeneration of flagellates were also present on the inner shelf in small flagellates. integrated chlorophyll levels were lower than the inner layers of the water column. On the middle shelf, where nitracline was found at 50 m. This shoaling was attributed to nutrients provided a possible source of nutrients to the obtained using a Sea-Bird 911plus CTD and analyzed for outer shelf, which was located near 75 in over most of the phytoplankton population was composed mainly of small pigments using high performance liquid chromatography (HPLC). present. High chlorophyll concentrations (up to 7475 ng 1-1) shelf, a mixed phytoplankton community was found. A deep shelf. On the western edge of the study area (94'00' W), the Study (LATEX A). Surface to bottom water samples were The relationships between phytoplankton pigment distributions the Texas-Louisiana Shelf Circulation and Transport Processes Upwelling at the eastern edge of the study area was were found on the inner shelf where diatoms were the dominant west of the study area during the cruise.
