Nutrient regeneration in sediments off Cap Blanc, Spanish Sahara
Deep Sea Research, 24(1):57-63.
Fluxes of nutrients out of the bottom sediments were measured off Cap Blanc, Spanish Sahara, by in situ incubation of the bottom under bell jars. The relationship of Si/N/P regenerated averaged 11/8/1. The average total nitrogen flux out of the sediments (410 μg-atoms M n−2 h−1) would account for approximately 30 to 40\% of the nitrogen presumed to be required for photosynthesis. Pore water nutrient concentrations were high over the 60 nautical miles square area investigated during the JOINT-I expedition, but tended to decrease offshore in deep water, and it can be presumed that sediment to bottom water fluxes of nutrients followed a similar trend.
