Bilim 2001 Black Sea Cruise
Two quasisynoptic survey of the South-western Black Sea region with near mesoscale resolution were carried out during May June 2001. The general plan were to obtain two quasisynoptic surveys of the region with near mesoscale resolution ~25 km and sub-mesoscale survey with finer resolution in areas of interest.
The survey was divided into two legs, each of about 6 days. The initial quasisynoptic survey, Leg 1, was carried out during May 22-28, 2001. The second leg was carried out during June 12-18, 2001. The network of stations for each leg is given in Figure.
The objectives of the following projects directed the cruise research plan.
Biogeochemical processes studies in the Black Sea, Marmara Sea, Aegean Sea and the Mediterranean and real-time forecasting studies (TUBITAK)
The Black Sea Ecosystem Processes, Prediction and Operational Data Managements (Supported by NATO)
General objective was.
to understand the physics and ecosystem dynamics of the South Western Black Sea region
Specific Objectives were
to understand the dynamics of the rim current along the western shelf and canyons
to quantify exchange of materials (passive, active) across the rim current, and the shelf-deep water,
to understand role of the mesoscale circulation on the ecosystem,
to acquire complete and coherent interdisciplinary observations,
to support studies and modeling in the region,
to acquire data to carry out hindcasting experiments with coupled physical and biological numerical model.
Bilim May-June 2001 Cruise
Summary of the measurements
SeaBird CTD equipped with temperature, conductivity, Beam Transmission, Fluorescence, PAR/Irradiance, pH and Oxidation Reduction Potential sensors were lowered at every station from surface to nominal depth of 500m.
Dissolved nutrients (PO4, NO3, NO2, NH4, and Si) using two-channel Technicon autoanalyzer were measured at samples collected with rosette system attached to CTD.
Chlorophyll-a and pheopigments-a using Spectrofluorometer.
Size fractionated Chl-a and primary production measurements for different size groups phytoplankton.
Determination of the phytoplankton (sampling by Niskin bottles) and zooplankton (net sampling) biomasses. Study on the taxonomic groups will be done for the determination of biodiversity.
Hindcasting studies using data collected in this cruise are continuing using Harvard Ocean Prediction System
