TECHNOLOGICAL AND OCEANOGRAPHIC COOPERATION NETWORK FOR THE STUDY OF MECHANISMS FERTILIZING THE NORTH-EAST AEGEAN SEA

Abstract: 

The inflow of colder and less saline Black Sea Waters (BSW) into the north Aegean Sea has an important impact in the area's hydrological and biogeochemical features, producing a highly stratified water column.

The above prevailing physicochemical conditions have been shown to sustain low mineral nutrient and autotrophic biomass concentrations but surprisingly elevated primary production rates during the spring bloom, in support of higher food-web trophic levels.

The hereby proposed research aims to study the mechanisms of:

  • the inflow of BSW and their impact on hydrology/biogeochemistry/ecosystem functioning of the N. Aegean Sea and
  • the seasonal wind-forced coastal upwelling, as well as their impact on the ecosystem productivity and the resulting gradient of CO2  at the air-sea interface.

New tools and novel techniques will be applied for the first time in Greek waters (e.g. coastal HF radars). The above will be combined with currently used methods in a strategy to develop long-term cooperation between the various participating academic and research groups, through the establishment of joint work-teams and common exploitation of new tools (e.g. observational platforms) and methodologies.

The expected results of this work are the following:

  • To maintain time-series measurements of lateral fluxes for buoyancy, inorganic nutrients and organic matter (carbon, nitrogen and phosphorus) introduced to the N. Aegean through the Dardanelles and to monitor the biological response of the marine ecosystem
  • To develop a region-specific calibration for satellite optical measurements
  • To complement the currently available infrastructure in the region (POSEIDON buoys) to the observations provided by the HF radar recently installed in the region and to in-situ hydrological/ biogeochemical/ecosystem measurements
  • To establish a fast-response team, charged with recording the hydrographic/biogeochemical conditions and biological response immediately after upwelling episodes
