    La información contenida en este conjunto de datos muestra la presencia/ausencia, así como la densidad de individuos de nacra (Pinna nobilis) por 100 metros cuadrados en diferentes puntos de la laguna del Mar Menor. La zona que comprenden los datos proporcionados abarca toda la laguna del Mar Menor, situada en el SW del Mar Mediterráneo, en la región de Murcia (España). Este conjunto de información se estructura en base a unos muestreos de densidad mediante buceo con escafandra autónoma realizados en la laguna del Mar Menor entre el 18 de noviembre de 2019 y 1 de diciembre de 2019. Se trata de un conjunto de datos compuesto por elementos puntuales, donde cada elemento representa el sitio de muestreo. Cada objeto tiene asociada una serie de variables alfanuméricas como son el código del punto de muestreo, la densidad (en individuos por 100 m2), el número de individuos (número total en ese sitio), y la profundidad encontrada en cada zona (en metros). La elaboración de este conjunto de información geográfica comenzó en diciembre de 2019, gracias a la campaña oceanográfica "MENOR_PINNA_1119", llevada a cabo en noviembre y diciembre de 2019 a bordo del buque oceanográfico "POSIDONIA SEGUNDO". La información geográfica recogida se almacenan en una base de datos espaciales. Estos trabajos se han financiado gracias al Proyecto LIFE IP INTEMARES (LIFE-IP INTEMARES - Integrated, Innovative and Participatory Management for N2000 network in the Marine Environment - LIFE15 IPE/ES/000012). Este proyecto integrado tiene el reto de sentar las bases para gestionar de forma eficaz los espacios marinos de la Red Natura 2000 y completar los trabajos y avances impulsados en el marco del proyecto LIFE+ INDEMARES, que logró dar un gran paso en materia de declaración de nuevos espacios.

    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 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.
