The bottom nepheloid layer (BNL) was investigated at a number of hydrographically different sites in the Gulf of Maine during August 1987. Observations were based on hydrographic measurements made from a surface ship and closely-spaced, near-bottom s

The effect of preconditioning nitrogen source and growth rate on the interaction between nitrate and ammonium uptake was determined inThalassiosira pseudonana (Clone 3H). A new method, using cells on a filter (Parslow et al. 1985), allowed continuous

Nutrient inputs have increased worldwide in both marine and freshwater ecosystems, stimulating algal growth. The resulting increased eutrophication can be manifested in different ecosystems as hypoxia/anoxia, loss of submerged aquatic vegetation, or

The interaction between nitrate and ammonium uptake was examined as a function of preconditioning growth rate and nitrogen source by adding nitrate, ammonium, or both to nitrogen-sufficient,-deficient, and-starvedSkeletonema costatum (Grev.) Cleve an

The supply and utilization of organic carbon in the deep western Mediterranean Sea was investigated based on measured electron transport system (ETS) activities of the nanoplankton and microplankton. The total carbon oxidation rate between 200 and 30

Depth profiles of particulate protein-nitrogen at 4 oceanic and 2 upwelling stations in the North Atlantic Ocean were measured by a new fluorometric method. The protein-nitrogen in the upper 20 m ranged from 0.19 to 1.61 μg-at N/1 at the oceanic sta

The uptake of nitrate and ammonium was measured separately in uni-algal, nitrogen-deficient cultures of four species of marine phytoplankton. Nitrogen-deficient phytoplankton took up ammonium at initial rates which greatly exceeded those measured for
