SEDMET-III CRUISE, RV GARCÍA DEL CID
- Palanques, Albert
- CSIC - Unidad de Tecnología Marina (UTM)
SEDMET-III Cruise (29GD20080228) carried out on the Research Vessel García del Cid in 2008, The maintenance tasks of the deployed equipment was performed, the bottom sediment was sampled and the hydrographic structure was recorded. The proposed research project consists in the study of the sediments and associated heavy metals dynamics, and very specially in determining the effect that the floods and storms exert on them, in a coastal system affected by industrial and urban activities. The coastal system of Besòs is one of the most polluted areas known and presents a complex situation with different sources of pollution (river, outfall, collectors, pluvial) and with an important historical contamination (since the beginning of the 20th century) from some of the these sources, which now also constitutes a contaminating source in itself. Although the presence of high levels of contamination in the prodeltaic sediments of the Besòs River is well known, studies of the dynamic processes that affect them and their repercussions have still not been carried out. To advance in the knowledge of this subject, the present project foresees to register during the season of floods and storms temporary series of currents, temperature and salinity, concentration of sediment in suspension and vertical flows of particles through the anchoring of instrumented oceanographic tripods, as well as the periodic realization of hydrographic profiles and of sampling of matter in suspension and sediments. At the same time, it is proposed to monitor the surface plumes of river and stormwater discharges by means of time series of video images acquired by an Argus system, and water and particulate samples and to take sedimentary cores to study the recent evolution of the deposit and make measurements of the critical resuspension conditions. With all this, we intend to 1) characterize the discharges of solids and associated heavy metals and nutrients from the Besòs River and the pluvial waters of the Barcelona seafront and determine in which situations they occur. 2). Study the transport processes, and the resuspension processes that affect the contaminated sedimentary deposit. 3). Determine the critical conditions under which the erosion and remobilization of current and historical contaminated sediments occurs. 4). Quantify the associated sedimentary and heavy metal flows. 5). Determine if the corrective measures applied in the Besòs basin are contributing to reduce historical pollution levels in the marine system. 6) Characterize situations of maximum risk that can contribute to establishing actions to forecast and prevent adverse conditions for the development of activities in the coastal zone. All this, placing special emphasis during events of storms, fluvial avenues and heavy rains. The knowledge of this dynamic has an application for the definition of potential environmental risks that affect the coastal system, and can contribute to improve environmental management within the scope of the European Community Water Framework Directive.The concrete activities. Instrumented tripods. 2 tripods will be installed. The main tripod will have a coherent pulse Doppler profiler (PCADP) and an acoustic profiler to measure the suspended sediment (ABS). An RCM9 correntimeter will be added to the tripod with pressure sensors, turbulence, temperature and conductivity and a sequential sedimentary trap. The triopods will be installed at a depth of 30 meters, one in front of the mouth of the Besos River and the other in front of pluvial waters. The final position will be adjusted after making a reconnaissance bathymetric and bottom sediment. Hydrological stations. CTD / turbidity / fluorometry transects perpendicular to the continental shelf will be carried out. Samples of water will be taken with the rosette that will be filtered on board to obtain samples of matter in suspension. The water samples will also be used to analyze nutrients, chlorophyll and to account for phytoplankton. Sedimentary stations (dredge, HASP and Boxcores). The surface sediments will be sampled with the dredge where the hydrographic stations are made. Sediment core samples will be taken with HASP and Boxcore where the instrumented tripods will be installed. The sediment cores will be sub-sampled for later sedimentological and geochemical analysis (granulometry, radiographs, heavy metals, C, N, CaCO3, dating with Pb)

NITROALBORAN CRUISE, RV GARCÍA DEL CID
- Mercado, Jesús M.
- CSIC - Unidad de Tecnología Marina (UTM)
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

The objective of the campaign was to study the intrusion of Mediterranean waters in the Gulf of Cádiz, with special emphasis on the structure of a Meddy detected in the area using altimetric data. This campaign used a Lowered Acoustic Doppler Profiler (ADCP) and a microstructure profiler (Turbomap) to study the currents and turbulence associated with the Meddy and in one of the submarine canyons south of the Iberian Peninsula

PERMILMED-I CRUISE, RV GARCÍA DEL CID
- Alcaraz, Miquel
- CSIC - Unidad de Tecnología Marina (UTM)
PERFILMED-I Cruise (29GD20080718) carried out on the Research Vessel García del Cid in 2008, In most of the plankton production models, space is not taken into consideration, as if the pelagic trophic relations took place in an evenly distributed universe. Food or predators are parametrised as average concentration values, although spatial heterogeneity and time variability (patchiness) at all scales is a constant characteristic for marine physical and chemical variables, as well as for plankton communities. The vertical structure of plankton in patches or layers has been described since long , but their effects on the coupling between the different trophic components and the oceanographic singularities that control the matter and energy transfer have been poorly studied. In order to allow us to explain some paradoxical features of consumers production under conditions of low average resource availability, in the Framework of the PERFIL-MED cruise we studied the time-changes on the vertical pattern distribution of meso- and microplankton in relation to physical heterogeneities during the summer stratification period. Profiles of physical (T, S), chemical (O ) and biological (fluorescence) data were made with a CTD SBE 911plus. The high-resolution vertical distribution of the rate of turbulent mechanical energy dissipation, epsilon, was obtained with a MST micro-structure profiler®. The vertical distribution of organisms ranging from 50 µm to 2 mm ESR was obtained with a TAPS® (high resolution acoustics, 6 frequency channels from 265 to 3000 KHz). For depthstratified plankton hauls (15-level, from 0 to 200 m depth) we used a LHPR® fitted with 200 and 50 µm-mesh gauzes, and the on-board analysis of microplankton was made with a FlowCam® on depth-selected water samples. All the profiles were obtained in the 0-200 m depth water column. The analysis of zooplankton biovolume, the organic C contents (from biovolume and a conversion factor), individual numbers and the identification of taxonomic groups, was made using the free software ZooImage® , which uses ImageJ® for the step of image analysis, and R for classification and data analysis
