The objective of the project RADIALES, started in 1990, aims at “understanding and modelling the response of the marine ecosystem to the sources of temporal variability in oceanographic and planktonic components, focusing on those factors and processes affecting biological production and potentially altering the ecosystem services”. This project is the oldest multidisciplinary ocean observation initiative still active in Spain.

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.

The main objective of this campaign is to obtain acoustic, sedimentary and biological data of the study area in order to obtain the necessary information for the declaration of this zone as SCI. For this, three specific objectives are contemplated: 1. Geomorphological and sedimentary characterization started in the INTEMARES MURCIA campaign 0118 and continued in the INTEMARES campaign A22MU-0819, from the acquisition and analysis of the bathymetric and reflectivity data obtained using the EM710 multibeam echo sounder and of the profiles of the TOPAS PS018 parametric echo sounder, combined with the collection of surface sediment samples using box-corer dredgers, short cores of gravity, dredge Van Veen and Shipek in the localities of interest that it was not possible to sample in the first two campaigns. The acquisition of acoustic data has as a priority complete the areas indicated by the bentos team to obtain photo images and video in the following campaign to be carried out on board the Sarmiento de Gamboa ship, and where they will use the ROV Liropus. 2. Bionomic characterization, also, to complete the information obtained in the previous campaigns carried out in the area with the aim of improving cartography fauna. In this case, all the surface samples obtained will be studied, and will process to obtain the biological material. 3. Obtaining hydrographic profiles at different depths to identify the bodies of water present in the different sectors of the study area.

The general objective of the INTEMARES-A22B-1019 campaign is to complete the geophysical mapping of the underwater mountains of the Canal de Mallorca and continue the biological characterization of its benthic and necto-benthic communities. For this, the following partial objectives are proposed: 2.1. Complete the geophysical mapping of the bottom that surround and link the mountains SO, AM and EB submarines, from data obtained with multibeam echo sounder and samples of surface rocks, collected with drag dredge. Priority 1 2.2. Complete the characterization of the benthic communities of sedimentary bottoms and rocky in these mountains and its surroundings, from samples collected with skate epi-benthic and trailed dredger, respectively. Priority 1 2.3. Perform seismic profiles with parametric echo sounder, to obtain information from the sedimentary structure. Priority 2 2.4. Estimate chondrichthyan fish diversity from environmental DNA analysis (eDNA) in water and sediment samples. Priority 2

This project is the oldest multidisciplinary ocean observation initiative still active in Spain. The objective of the ESGOBA sampling was to confirm or reject the presence of bluefin (Thunnus thynnus) and Atlantic bonito (Sarda sarda) larvae in the southern Bay of Biscay
