Get more information regarding the characteristics and distribution of benthic habitats present inside the Columbretes Islands Marine Reserve with the objective of Develop a bionomic map that covers the total extent. The complementary objective is the realization of the benthic cartography. It is intended to achieve location and subsequent georeferencing of the upwelling of gases present in the environment of the volcanic archipelago that forms The study area of this campaign. Associated with this objective is intended to know the Bacterial community in the area of gaseous upwellings and a physicochemical characterization of these areas.

This cruise continues with the line started in previous years cruises with the general operational target of the registration of oceanographic parameters and obtaining water samples and various types of suitable and sufficient plankton for the achievement of the following specific objectives: 1- Obtaining data on larval densities and CTD profiles to estimate Larval abundance indices for species of the genus Thunnus in the Balearic Sea. 2- Determine the influence of hydrographic scenario on the structure, distribution and condition of large and medium pelagic larval populations in the Balearic Sea, with special attention to Atlantic bluefin tuna. 3- Identification of the hydrographic processes that determine the productivity of the pelagic ecosystem of the Balearic Sea. 4- Characterization of the genetic structure of the larval populations of bluefin tuna and related species in the Balearic Sea, used for the 'close-kin' studies recently initiated by ICCAT. 5- Evaluate the possibility of using acoustic methods in the characterization of bluefin tuna populations and the distribution of larval habitats.
