BUSCADOR RECOLECTA

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
