Oceanographic survey collected in the framework of the following research project: ¿Métodos de Producción de Huevos. Estimación de la biomasa de especies pelágicas de interés comercial: sardina, anchoa, caballa y jurel (ICTIOEVA)¿. This Project is funded by the Instituto Español de Oceanografía and the main scientific objective is to produce an index and a direct estimate of the biomass of the Northeast Atlantic mackerel stock and the southern and western horse mackerel stocks using the Annual Egg Production Method (AEPM). Specific aims:a) To estimate the spawning area distribution of mackerel and horse mackerel and the daily and total mackerel and horse mackerel egg production. b) To collect adults to obtain mackerel and horse mackerel gonads for atresia and fecundity estimation c) Distribution and abundance of other commercial species of interest: sardine, anchovy, hake, blue whiting.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 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

Abundance indices, distribution patterns and faunal assemblages of demersal species in the northern coast of Spain (Atlantic Galician shelf and Cantabrian sea shelf), together with the possible driving factors of their distribution. This survey belongs to the research project: ¿Evaluación de Recursos Demersales por Métodos Directos en el Área ICES¿. This Project is partly funded by the DCR of the EU and the Education and Science Spanish Ministery.The main objectives of the above mentioned project related with this survey time series are: a) to obtain abundance indices of the main exploited species in the study area; b) to estimate the strength of yearly recruitments of these species and their distribution in the area. c) to study the structure and distribution o the demersal and benthic communities in the area.

The main objective of the project ATLANTIS is the study of fishing activities and marine resources of commercial interest in the FAO statistical subareas 41.3.1 and 41.3.2, within an ecosystem approach, paying particular attention to interactions between fishing activities and Vulnerable Marine Ecosystems, mainly on the High Seas of the SW Atlantic. From 1988 the IEO scientific observers onboard programme, gives commercial, biological, oceanographic and physical data (bathymetry, surface and sea bed temperatures, etc). A series of research cruises were carried out from 2007, on board the R/V Miguel Oliver, with the main objective of said research cruises was the quantitative, qualitative and geographical study and identification of the Vulnerable Marine Ecosystems and of the vulnerable organisms in the taxonomic groups who could live in the study area, including the proposal of marine areas to be protected, to allow sustainable exploitation of fishing resources without endangering the Vulnerable Marine Ecosystems. During the research cruises undertaken, from the surface to 1,500 m, in the south western Atlantic waters between 42ºS and 48ºS, a variety of data was obtained from the fieldwork on geology, geomorphology, benthos, fisheries and physical oceanography. The results include: a detailed cartographic and bathymetric study of the area, a description of the geological substratum and of the benthic features, an analysis of the abundance and distribution of the species of largest commercial fishing interest, a footprint analysis of the fishery, an identification and a description of the Vulnerable Marine Ecosystems. The research undertaken and its main findings led to the delineating of several areas to be protected, with a total area of 41,000 km2, according to presence of organisms classified as vulnerable.
