Oceanographic survey collected in the framework of the PESCADIZ, STOCA and INGRES3 projects. PESCADIZ is funded by the Instituto Español de Oceanograf¿a / DCRP and the main scientific objective is to produce an index and a direct estimate of the biomass of demersal target species in the Gulf of Cádiz together with the hydrographic caracterization at the time of the cruise. STOCA is a program conducting systematic hydrographic and plankton observations along three standard sections in the eastern Gulf of Cadiz. INGRES3 is a Spanish Ministry for Science and Innovation funded project that maintains a mooring line at the Spartel sill in the Strait of Gibraltar

The main goal of the INDEMARES CHICA 0211 oceanographic cruise was to study the associated habitats and the environmental conditions related to areas of the gas seepages in the Gulf of Cadiz. For this, the sampling in different mud volcanos was planned using a various methodology: fishing trawl, beam trawl, box corer, gravity corer, benthic trawling dredge, ADCP, and oceanographic sampling carousel (CTD, ADCP, oximeter, turbidity sensor, fluorimeter).The survey was carried out between the 10th February 2011 and the 7th March 2011 having Cadiz as a base port. The fair-weather remained during the campaign except on the 16th February because of the storm conditions.Mud volcanoes (Albolote, Gazul, Anastasya, Tarsis, Pipoca, Chica, Aveiro, Hesperides and Almazan) were sampled on the top, on the slope and on the adjacent areas of each one with the methodologies before mentioned. So, it was collected the following samplings: 47 benthic trawling dredges, 31 beam trawl, 12 fishing trawl, 40 box corers, 10 gravity corers, 132 CTDs and 84 oceanographic sampling carousel.The preliminary results have confirmed the existence of habitats associated with the gas seepages, and other habitats that are included in the Directive Habitats 2000 and OSPAR, as gorgonian reefs over carbonated hard substrate, coral bamboo fields, Isidella, in muddy seafloor, deep sponge aggregations,and communities of the Pennatulacea and of the burrowing megafauna on soft bottoms.

Oceanographic survey collected in the framework of the following research project: - Métodos 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 Espanol de Oceanografia and the main scientific objective is to produce an index and a direct estimate of the biomass of the Gulf of Cadiz anchovy stock using the Daily Egg Production Method (DEPM). Specific aims: a) To estimate the spawning area distribution of anchovy and the daily and total egg production. b) To collect adults to obtain anchovy gonads for atresia and fecundity estimation c) Distribution and abundance of other commercial species of interest: sardine, horse mackerel 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

Oceanographic survey collected in the framework of the following research project: ?PROCESOS MORFO-SEDIMENTARIOS Y ESTRATIGRAFIA DE ALTA RESOLUCION DE DEPOSITOS MARINOS SOMEROS EN LATITUDES MEDIAS: REGISTRO DE LA VARIABILIDAD AMBIENTAL Y APLICACIONES PARA LA GESTION COSTERA (CTM2005-04960/MAR)?. This Project is funded by the Education and Science Spanish Ministery for the period 2006-2008.The above mentioned project has two main scientific objectives: a) to determine recent environmental changes (oceanographic and sea-level influences) imprinted in shallow-water deposits previously identified in a sector of the Gulf of Cadiz shelf close to the Straits of Gibraltar; b) to apply the knowledge about sedimentary processes and architecture of shelf deposits to the coastal zone integrated management.
