| Summary: | (>30:1) suggest likely P-limited area near Southwest Pass activities were highest in the same area as in vivo and LS showed low DIP concentrations, from 0 to 0.5 gM, AP activities were fluorescence. AP activities up a e rates area near Southwest Pass and southwest of Atchafalaya Bay Bay during leg 1, while AP activities suggest P-limitation concentrations were up to 3.5 jiM in the freshwater portions during both cruises. Highest N/P and many high Si/P were during leg 1. Highest chlorophyll a concentrations were during leg 1. Dissolved organic phosphorus (DOP) and during leg 2. fluorescence were found directly west of Southwest Pass. fluorescence. AP activities and Pi uptake rates suggest P found off of Southwest Pass. The area with a high N/P was found west of Southwest Pass. The highest values of in vivo From west of Southwest Pass to near Atchafalaya Bay during High AP activities and Pi uptake rates were found in Surface large leg1, while AP activities suggest P-limitation in limitation from west of Southwest Pass to n . ear Atchafalaya Mississippi River Plume (MRP) and Louisiana shelf (LS) were of each river and decreased to less than 0.5 liM at 30 psu particulate phosphorus (PP) also decreased with increasing phosphatase (AP) activities, and orthophosphate (Pi) uptake Phosphorus (P) cycling and possible P limitation in the Productivity (NECOP) cruises in May 1992. Horizontal and rates were examined. Dissolved inorganic phosphorus (DIP) salinity. Maximum DIP concentrations near Southwest Pass smaller during leg 2. The low DIP (< 0.2 IiM) and high N/P studied during two Nutrient Enhanced Coastal Ocean vertical distribution of P pools, nutrient ratios, alkaline were found in nearshore areas near Barataria Bay. Surface AP were less during leg 2 than leg 1. The entire area of the MRP |
