Transfer of seston lipids during a flagellate bloom from the surface to the benthic community in the Weddell Sea
Total lipid and fatty acid concentrations were studied in a late spring-early summer flagellate-dominated bloom in the Weddell Sea. These indicators were considered a good tool for assessing the quality of organic matter settling from surface to deep-water layers (epibenthic water layers). The resul...

Total lipid and fatty acid concentrations were studied in a late spring-early summer flagellate-dominated bloom in the Weddell Sea.

The results showed different patterns between the early (11-15 December 2003) and the late sampling period (18-27 December 2003) at all studied depths (5 m, 50 m and near-bottom water layers). Low phytoplankton biomass (mainly flagellates) in the first half of the study corresponded to low total lipid and fatty acid concentrations. In the second sampling period a spring bloom (mainly flagellates and diatoms) was detected, increasing the total lipid and fatty acid concentrations in the water column. The amount of settling organic matter from surface waters to the near-bottom water layers was high, especially in the late sampling period.
