The MEDITS_ES 2007 is an annual bottom trawl survey for estimation of the abundance and biomass of demersal species that are present in the Mediterranean Sea in spring, obtaining abundance indices of these species, as well as biometrical and biological information on species and communities. Complementary to these main objectives, also sampling for biological parameters estimation of 35 selected species were conducted. In addiction, in each haul, a sampling of temperature and salinity for water mass characterization was done, using a CTD.

Oceanographic survey collected in the framework of the following research project: 'Metodos de Produccion de Huevos. Estimacion de la biomasa de especies pelagicas de interes comercial: sardina, anchoa, caballa y jurel (ICTIOEVA)'. This Project is funded by the Instituto Español de Oceanografia and the main scientific objective is to produce an index and a direct estimate of the spawning stock biomass of Sardine (Sardine pilchardus) in the Cantabrian Sea and Bay of Biscay (to 45°N) using the Daily Egg Production Method (DEPM). Specific aims:a) To estimate the spawning area distribution of sardine and the daily egg production. b) To collect adults to obtain fecundity estimation c) Distribution and abundance of other commercial species of interest: mackerel, horse mackerel and anchovy.d) To describe the oceanographic and meteorological character of the area of study with the aim of relating environmental conditions (temperature, salinity, currents) with the spatial distribution of the ichthyoplankton

The objectives of this cruise are framed on the project "Radial Profunda de Canarias (RAPROCAN-II)". This Project is funded by the Instituto Español de Oceanografía and the main scientific objectives are: a)Characterize the different ways of variability of heat and mass transport at the eastern end of the subtropical gyre. b)Determine the structure of current that reaches the Canary Islands, their mass transport, heat and nutrients and their interannual variability. c)Determine the correlation between heat and mass transport with the atmospheric and oceanic NAO index. d)Characterize the annual cycle in the physical condition of the surface and mixed layers as far as the seasonal cycle is significant, relating to meteorological forcing. e)Characterize of changes in water masses, mainly in the North Atlantic Central Water (NACW), Intermediate Water (AAIW), Mediterranean Water (MW) and bottom water of the Canary basin, studying their characteristics of temperature, salinity, nutrients and oxygen.
