Seasonal and mesoscale variability of biological and chemical parameters related to the hydrodynamics of the Ibiza Channel
The general objective of the RADMED-DOS project is the multidisciplinary monitoring of the platform and deep waters of the Mediterranean, the peninsular coast and the Balearic Islands.
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 general objective of the RADMED-TRES project is the multidisciplinary monitoring of the platform and deep waters of the Spanish Mediterranean, the peninsular coast and the Balearic Islands.
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
Prácticas dirigidas a los alumnos de la asignatura Practicas Integradas del Master de Ecología Marina de la UIB, con el objetivo de trabajar in situ las principales técnicas oceanográficas para la adquisición de información de la columna de agua y la obtención de muestras de agua y organismos del plancton y del bentos, visualización del fondo marino con ROV y otros equipos de observación.
The main objectives are understanding the inter-annual variability of Bluefin Tuna spawning sites and the application of operational oceanography to the conservation and management of tuna species in the Balearic Sea. The main activities have focused on the development of predictive models of Bluefin Tuna spawning locations.
1.Estimar índices de abundancia de reclutas y juveniles de langosta. 2.Determinar la estructura demográfica y distribución batimétrica de los juveniles. 3.Estimar la abundancia y demografía de la langosta mediante técnicas de video sumergido con cebo. 4.Evaluar el efecto de la ampliación de la reserva marina mediante video sumergido y censos visuales. 5.Obtener muestras de ejemplares recién asentados talla inferior a 15 mm LC (Longitud de Cefalotórax) para estudios de genética de poblaciones y composición isotópica.
