SARDINA Cruise (29GD20000502) carried out on the Research Vessel García del Cid in 2000, Effect of oceanographic processes on the distribution and feeding of the larvae of Sardina pilchardus, and their consequences on growth, on the Asturian coast.A total of 11 stations were sampled during the daytime (09:00 to 13:00 h) along 4 transects perpendicular to the coast . Vertical profiles of temperature, salinity and fluorescence were taken at each station using a Mark III CTD with a Sea-Tech fluorometer attached to a rosette of 24 Teflon Niskin bottles. Live experimental animals were collected with a triple WP2 net (0.60 m diameter, 200 µm mesh) equipped with 3 l cod-ends. Hauls were made vertically from 200 m to the surface, or from 5 m above the bottom to the surface at the coastal stations. Once on deck, 1 or 2 cod-ends were immediately processed for gut pigment content analysis. Another haul was made and the 3 cod-ends were diluted in a 5 l plastic jar filled with 100 µm-filtered seawater to ensure that the animals remained alive for our experiments. Water used for the incubations was collected with Van Dorn bottles (15 l) from the depth of maximum fluorescence (MFD). Bongo net hauls were performed to collect zooplankton samples for abundance estimations as described in González-Quirós et al. (2004). A bongo net (0.60 m diameter, 200 µm mesh) equipped with calibrated flowmeters was towed obliquely from 200 m to the surface, or from 5 m above the bottom to the surface at coastal stations

GOLFO Cruise (29GD20000508) carried out on the Research Vessel García del Cid in 2000, Study of the physical and biological processes that affect the Gulf of Cadiz region

ARO Cruise (29GD20000530) carried out on the Research Vessel García del Cid in 2000, Multidisciplinary monitoring of a body of water of continental origin from the Rhone and its involvement as a transport mechanism of anchovy larvae.Measurements of basic hydrographic parameters were obtained with a MARK-III Neil Brown CTD at 68 stations arranged in transects that covered the whole continental shelf to beyond the shelf-slope front, from northern shelf to central shelf.At each station, samples of phytoplankton (which includes a component of detritus), zooplankton and anchovy larvae were taken for the determination of fatty acids. For pigment analysis of phytoplankton, 2 L of water collected by Niskin bottles was filtered with low (0.25 bar) positive pressure through Whatman GF/F glass fibre filters that were immediately frozen in liquid N2. Pigment samples were taken between 4 and 30 m depth (surface samples).Zooplankton (>53 μm) was sampled by vertical hauls from 70 m (below deep chlorophyll maximum) to the surface with 40 cm diameter plankton net,Anchovy larvae were sampled by oblique tows using a Bongo net with a 60 cm diameter opening and a mesh size of 333 μm

ARPA Cruise (29GD20000620) carried out on the Research Vessel García del Cid in 2000, Performing day-night trawls for detection of prawn activity rhythms and underwater photography transects

NERIT-II Cruise (29GD20000622) carried out on the Research Vessel García del Cid in 2000, Performing day-night trawls for detection of lobster activity rhythms and underwater photography transects

CRAC Cruise (29GD20000913) carried out on the Research Vessel García del Cid in 2000, The objective of the campaign is to make precise determinations of sea level using light buoys with GPS antennas at the time of the passage of the altimetric satellites ERS-2 and TOPEX / POSEIDON. As a complement, CTD stations will be made (without taking samples from water) and continuous radial with ADCP and Nu-Shuttle along some of the traces of these satellites

CAÑONES-I Cruise (29GD20010313) carried out on the Research Vessel García del Cid in 2001, Multidisciplinary study of the dynamics of a submarine canyon and its impact on the ecology of the continental margin of the western Mediterranean. 8 anchors with correntimeters and sediment traps will be placed in the area of ​​the Palamos canyon. 46 CTD stations will be made and samples of water will be taken with the rosette of 24 bottles. Doppler transects will be made in navigation
