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: ?Evaluacion de Recursos Demersales por Metodos Directos en el Area 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.

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.

The aim of this cruise was to develop a better understanding of carbon cycling in the pelagic waters of the Porcupine Abyssal Plain (PAP). There were three objectives: 1) Turnaround moorings at the PAP Observatory; 2) Conduct a 1-D time series on the central station of a wide range of biogeochmical processes and to back this up with a mesoscale survey of key variables; 3) To trial the use of Autosub for mesoscale surveys in conjuction with the ship. All objectives were met, although the tops of the moorings were found to be missing probably due to fishing activity and the Autosub trials were incomplete due to vehicle failure. A full mesoscale survey was carried out using the ship and an eleven day time series at the central station was achieved. Friday 23 June [JD174] Scientific party met at 13:00 to agree work plans. The Master gave welcome & safety talk at 15:00. We sailed at 18:00 after a series of delays. The Chief Officer was discharged off sick and a replacement was travelling from Lincolnshire. On reaching Plymouth, the railway shut due to a suicide on the track. The replacement mate required taxi from Plymouth to Falmouth. One of the ship's cranes broken, compromising our ability to handling moorings. The ship's engineers worked flat out yesterday and today and managed to cannibalise parts from other cranes. On sailing we moved into the lee of Falmouth Bay to carry out ship's compass check and then deployed Autosub briefly to check its sensors were working. The sea-state was surprisingly benevolent considering how hard the wind had been blowing for previous 3 days. The skies were still very cloudy. Saturday 24 June [JD175] We made an easy passage with winds BF 3-4. The scientists were finding their sea-legs, with no major problems. An Emergency muster & life boat drill was run at 10:30. We had a discussion about Autosub mission and decide to work the central box at PAP for the first deployment.

The overall objective of the cruise was to perform a systematic geophysical survey. Particularly its main aim is to get a complete sea-floor coverage.The investigation is the result of a co-operation between the Royal Observatory (ROA) and the Hidrographic Institute (IHM) (both from the Spanish Navy) under the control of the General Technical Secretary of the Spanish Dpt of Defense. (SEGENTE), with the collaboration of several other Spanish institutions and universities.The cruise started on Sept. 19th at Cadiz. Gordon's Tropical storm as well as some tecnical problems related with the multi-beam echo sounder (Simrad EM-120) conditioned its kicked-off. This technical failure limited us to work at shallow waters, changing so our initial planning. Finally we ended at Coru?a on October 9th.
