Physical oceanography and productivity at the Weddell-Scotia confluence.
Listed in NASA Earthdata CMR
In English: Spanish contribution to the DOVETAIL international project.
Description
The objectives of this campaign were: -Physiochemical characteristics of Weddell Sea waters acting as a source for the Weddell-Scotia confluence. -Dominant physics processes associated to the subsidence and spreading of the dense Antarctic waters at Weddell-Scotia confluence. -Ventilation rates of the global ocean across the Weddell-Scotia confluence. -Variability of the hydraulic transport and hydrographic structure, influence on the oceanic ventilation rates. -Distribution of phytoplanktonic communities in front lines zones.
Characterization of the photosynthetic pigments distribution by liquid chromatography. Evaluation of the phytoplankton abundance by microscopic counting and flux citometry. -Presence, distribution, abundance and specific composition of meso and macrozooplankton related to masses of water. Analysis of the association of the different existing groups, changes in depth and nictimeral migrations.

Growth studies, physiology and trophic relations of fish larva. -Distribution and remineralisation of dissolved organic carbon (DOC) and particulate organic carbon (POC) in the water column, and influence of waters constituted in the Weddell Sea in the DOC transport. -Execution of metabolism (production and breathing) experiment in phytoplankton by means of incubations on board and in situ. Photosynthetic and respiratory quotient calculation, and DOC exudation rates.
