The overall objective of the cruise was to perform a systematic geophysical survey. The principal aim is to obtain complete bathymetric sea-floor coverage. There are other geophysical data obtained during the cruise, whose acquisition is compatible with the navigation requirements of the multibeam survey, such as gravity, geomagnetic and ultra-high resolution seismic data (TOPAS system).This project is the result of a cooperation between the Instituto Hidrografico de la Marina (IHM, Hydrographic Institution of the Spanish Navy) and the Real Observatorio de la Armada (ROA, Royal Observatory of the Spanish Navy), under the control of the Secretaría General Técnica del Ministerio de Defensa (SEGENTE, General Technical Secretary of the Spanish Defense Department), whith the collaboration of several other institutions and universities.The cruise started on August 29th at Cartagena and finished at La Coruña on September 13th. It was planned in order to cover two bathymetric charts (G17 and G18) to the NW of Galicia, but the bad weather led to complete only bathymetric chart G17 and partially G18.

It was planned in order to cover two bathymetric charts (G7 and G8) to the NW of the Galicia Bank, but the good course of the works allowed to go beyond this first objective and finalize also chart G9, which was only partially covered during ZEE-2003 cruise.

PELACUS Give an improved estiamtion of the abundance of pelagic fish present in the NE Atlantic waters in spring which is the spawning period for these fish species, but focussing in sardine and anchovy. Complementary to this main objective the survey design and strategies will allow the enviroment be characterised by recording differente variables (i. e. t/S, fluorescence, plankton, winds or air temperature) in vertical and horizontal profiles along the surveyed area with no noticeable extra-effort. As it was pointed out, these variables will help the acoustic estimations be improved whilst an extensive environment characterisation at the spawning time will be done. - ref 0403

Oceanographic survey collected in the framework of the following research project: ?Metodos 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 Espa?ol de Oceanografia 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
