BUSCADOR RECOLECTA

NITROALBORAN Cruise (29GD20080509) carried out on the Research Vessel García del Cid in 2008, During May 2008 Nitroalboran cruise was carried out on board of the oceanographic vessel “García del Cid. An important activity conducted during the NITROALBORAN research cruise is the collection of water samples for measurements and use in experiments. Upon reaching a station, a rosette sampler mounted with a conductivity, temperature, and depth recorder (called a CTD) and Niskin sampling bottles was lowered through the water to the bottom. The CTD measures how physical (water temperature,salinity, and density); chemical (dissolved oxygen); and biological (chlorophyll a fluorescence) characteristics change with water depth and produces a profile of theseparameters in the water column. Closure of the Niskin bottles can be triggered from the ship, allowing seawater to be collected at selected depths. During the Nitroalboran research cruises zooplankton was collected for experiments using plankton nets that are pulled, or towed, through the water
