BUSCADOR RECOLECTA

CACO-1 Cruise (29GD20030721) carried out on the Research Vessel García del Cid in 2003, The project proposes a continuous sampling of oceanography and plankton 24 hours a day.The general objective of this project is to analyze the possible variations experienced by the climate in the last decades with significant changes in the composition, distribution and abundance of fish communities on the Catalan coast. It is intended to study the variation in the distribution and abundance of those fish species more vulnerable to changes in the environmental conditions, especially the temperature of the water, in the last 20 years on the Catalan coast. We will focus on pelagic species of warm waters, which are the ones that respond most quickly to an environmental change. Therefore, samplings should be made in summer.Sampling was carried out during July 2003 and July 2004, coinciding with the spawning period of Sardinella aurita and Engraulis encrasicolus. Determination of the basic hydrographic parameters was performed with CTD casts at stations distributed along transects, from near the coast to the shelf edge, along the Catalan coast (NW Mediterranean).. The CTD employed was a Neil Brown Mark III with an attached SeaTech fluorometer. Profiles of temperature, salinity, density and fluorescence were averaged at 1 m intervals.To determine the vertical distribution of fish eggs and larvae, sampling was focused on 2 areas of the Catalan coast where the continental shelf was relatively wide: one in the southern part, which was called the ‘southern area’ and the other in the north that was denoted the ‘northern area’.Vertically stratified zooplankton samples for fish larvae (45 cm mouth diameter, 333 µm mesh) and microzooplankton (9 cm diameter, 53 µm mesh) were collected simultaneously using a double Longhurst-Hardy Plankton Recorder net (LHPR)

VEDA-4 Cruise (29GD20030728) carried out on the Research Vessel García del Cid in 2003, The purpose of the VEDA campaigns is to analyze the response of the organisms and sediments to a veto period of the trawling fishery.Collection of samples of infauna and sediments from the study area and recording of the process followed by the material resuspended by the trawl. Recording of oceanographic and environmental data. The campaigns must be carried out according to the activity of the trawling fleet. The campaigns will be carried out in the province of Tarragona , in the area of influence of the ports of the Atmella and San Carles de la Ràpita

RECS-4 Cruise (29GD20030903) carried out on the Research Vessel García del Cid in 2003, Characterize the temporal and spatial variability of water and particle flows in the area of the Blanes canyon. Determine the seasonal and suvestational variability of the population structure of the shrimp Aristeus antennatus. Interaction of the submarine canyon environment with the physiological state of the associated shrimp resource. Spatio-temporal determination of the population structure of shrimp linked to the submarine canyon. Detection of recruitment areas and application of new technologies for their preservation

MFSTEP-1 Cruise (29GD20030922) carried out on the Research Vessel García del Cid in 2003, The objective of the campaign is to test 4 profiler buoys that should be ready (according to the work plan) 6 months after the start of the project. Test of a anchored mooring with correntimeter and MicroCat probe. CTD and ADCP profiles will also be made and the buoys will be launched in 4 different points

BIOMEGA Cruise (29GD20031009) carried out on the Research Vessel García del Cid in 2003, The campaign aims to carry out a sampling in the transition zone located between the western and eastern Alborán Sea. This zone is characterized by the presence of highly active mesoscale structures (10 to 100 km in size) such as fronts and eddys formed as a result of the interaction between incoming Atlantic waters through the Strait of Gibraltar and the Mediterranean waters resident in the alborán basin. Specific objectives -Make a high resolution CTD mesh (10 days) -Make a yoyo CTD station for 24 hours -Make sampling with LHPR plankton net (2 days)
