The general scientific objectives of the MEDOCC cruise were to achieve the following objectives: 1. Water mass properties and circulation features. (a) to define the principal circulation paths and the physical-chemical-biological properties (temperature, salinity, oxygen, nutrients, dissolved organic carbon, colored dissolved organic matter, etc) of the superficial, intermediate and deep water masses in the central part of the Western Mediterranean Sea, through measurements along key sections located in the interior and at the boundaries of the basin; (b) to select some transects with the purpose of performing long term surveys. 2. Carbon cycle. (a) to estimate the particulate carbon export from the photic zone in some significant stations and the relationship to hydrology and biological parameters; (b) to investigate the linkage between the quantities and qualities of DOC and CDOM (e.g. specific absorbance, spectral slope and specific spectral slope) and to study the interactions of these parameters with the spectral irradiance in the water column; (c) to study the optic characteristics of the water column in the visible and UV solar bands, to measure UV-B, UV-A and PAR radiation on the water surface, to evaluate reflectance on the water surface; (d) to quantify and classify phytoplanktonic populations; (e) to measure the sedimentation rate in three key areas; 3. Cetacean Research - to study cetacean communities and to map the distribution of mesopelagic fauna related both to the presence of cetaceans and to hydrology in the Ligurian–Provencal Basin; 4. Methodological development. (a) to use conventional techniques to calibrate acoustic backscatter data obtained using an Acoustic Doppler Current Profilers, to derive estimates of suspended solids concentration on the column water; (b) to compare different chlorophyll quantification methods and to calibrate the fluorimeter coupled with the CTD-probe with different photochemical techniques. This dataset was acquired during the cruises MEDOCC06 in June 2006 using discrete water samplers. The chemical parameters analyzed were nitrate and nitrite concentration, phosphate and silicate.
