EVENT-SHELF CRUISE, RV GARCÍA DEL CID

  • Bartolomé, Rafael
  • CSIC - Unidad de Tecnología Marina (UTM)
EVENT-SHELF Cruise (29GD20080906) carried out on the Research Vessel García del Cid in 2008, Integration of new technologies in paleosismology: General aims:Characterization of seismogenic and tsunamigenic faults in South Iberia.a) to characterize the seismic potential of the Eastern Betics Shear Zone; 2) to adapt the paleoseismological methodology to the analysis of slow moving faults,and 3) training young researchers in onshore-offshore paleoseismology. Specific works: To achieve the main objectives of the EVENT-SHELF cruise in the Eastern Betics Shear Zone (EBSZ) area, we carried out a geophysical exploration (swath bathymetry, acoustic backscatter and high-resolution single-channel sparker seismics) of the Adra/Carboneras, Palomares and Bajo Segura fault zones on the shelf areas. During the cruise we have adapted high resolution- low penetration geophysics to the paleoseismological analysis of the EBSZ fault terminations located on the continental shelf, often difficult to image with conventional low-resolution systems. Major destructive events occurred in some of the areas investigated during the cruise, such as the 1522 Almería (EMS IX Intensity), the 1829 Torrevieja (EMS X Intensity) and the 1910 Adra earthquakes (EMS VIII Intensity) (IGN, 2005). Most of the acquired profiles were oriented perpendicular to the fault orientation and other few profiles were acquired to explore the structure of deep-coral mounds in the Chella Bank [11]. Moreover, ROV and towed camera transects were carried out along some of the coral-mound to obtain visual groundtruthing of the acoustic data. Methods The following methodology was used during the EVENT-SHELF cruise: • High resolution seismics. During the EVENT-SHELF cruise we used a high-resolution single seismic system on board the B/O García del Cid able to acquire data with a 30 cm of resolution at 1.5 km depth. The source, a sparker GEO-SPARK 6kJ from GEO-RESOURCES BV (www.geo-resources.com), is specially designed to favour high frequencies . The receiver consisted on a 9 m long, 24 channel, streamer. Part of the data was processed on board with the specific software Geotrace supplied by the company. • Bathymetric survey. Simultaneously with the seismic survey, we acquired information regarding seafloor morphology (bathymetry and backscatter) with the double frequency (180-50 kHz) Elac Nautik SeaBeam 1050D available in the B/O García del Cid and managed by the Unidad de Tecnología Marina (UTM, CSIC). Only data with less than 350 m depth were acquired due to technical acquisition problems in the echo-sounder (50 kHz low frequency MB not functioning). • Visual groundtruthing. Visual inspections was carried out in the deep- coral mounds area of the Chella Bank. Video transects allowed to visualize and record seafloor images, helpful to calibrate backscatter and seismic data in areas where deep coral mounds occur, and to detect and recognize the benthic assemblages present in the seamounts of the Almería Margin. The remotely operated vehicle (ROV) SPY-ICM Mariscope (provided by ICM-CSIC) was used for the shallowest transects (100-200 m), whereas the deep towed video-camera DTS6000 Seatronics was used in the deepest mounds of the Chella Bank (200-400 m) • Sediment sampling. A 25 l Van Veen dredge was also deployed to collect sediment samples in a subaqueous dune field and in a coral rubble area identified in the Chella Bank

CASCADES-1 CRUISE, RV GARCÍA DEL CID

  • Puig, Pere
  • CSIC - Unidad de Tecnología Marina (UTM)
CASCADES-1 Cruise (29GD20081017) carried out on the Research Vessel García del Cid in 2008, Interaction between submarine cascades and deep ecosystems. CASCADES main objective is to study the processes of particle transport associated with the descent, in the form of underwater cascading , of dense waters formed in coastal environments, and at the same time, to evaluate in an interdisciplinary way the effects implications of this oceanographic phenomenon in ecosystems and deep living resources. To achieve this objective, it is necessary to record time series of oceanographic parameters in winter conditions (time when the underwater cascading) through the use of anchored instruments. This fact entails the need to request a minimum of two oceanographic campaigns (one to install the anchoring and another for its recovery). During the first days of the CASCADES 1 campaign operations will be carried out related to the anchoring of instruments to ensure the registration of parameters oceanographic,three hydrographic transects will be carried out a CTD probe following a direction parallel to the orientation of the canyon, on the flank north, on the axis and on the south flank, and two perpendicular to the canyon. The stations will be separated one nautical mile from each other to characterize the structure in detail hydrographic and nephelide in the head of the submarine canyon and in the continental slope adjacent.also sediment samples will be collected

DEEPCORAL-IV_CORAL-9 CRUISE, RV GARCÍA DEL CID

  • Gili, Josep Maria
  • CSIC - Unidad de Tecnología Marina (UTM)
DEEPCORAL-IV_CORAL-9 Cruise (29GD20090214) carried out on the Research Vessel García del Cid in 2009, Study of the communities of deep corals in the margin of the the mediterranean continental shelf.The main objective of the project is the study of the role of the communities of benthic suspensible organisms in the platform-slope areas in the processes of transfer of matter and energy, as important creators of habitat (three-dimensional structure), reservoirs of biological diversity and areas of protection and breeding ("nurseries") of numerous pelagic and nectonic species, some of them of commercial interest. The project is an integrated and multidisciplinary study of these communities in the north-western Mediterranean, with special emphasis on the headwaters of the submarine canyons. Knowledge of the specific composition of the communities, their distribution, both geographic and batimetric, their intra-interspecific and intra-occupational relationships and the environmental characteristics of the habitat are the first studies to be developed in the first phase of the project. Once these bases on diversity and structure have been established, a second phase of the project will be focused on the ecology (function) of these communities with the study of key species in the studied systems. Experimenting with living organisms (mainly cnidarians and sponges) will allow you to know different aspects of their ecology and the influence these communities have on the planktonic and benthonic system. Other important objectives of the project will be to analyze the influence of the benthic suspensible organisms on the microbial trophic chains of the layers of the water column closer to the bottom and the study of epibenthenic zooplankton communities. Knowledge of the dynamics of these communities will allow them to make a proper management plan for them, as well as, if necessary, the creation of reserve areas due to their importance as areas with high biodiversity, Commercial interest and role in the processes of transfer of matter and energy along the platform-slope axis. The project is carried out in collaboration with the company PRAESENTIS with the purpose of developing a new submarine vehicle prototype equipped with cameras of video and photography (EVO) and the Organization ADENA Spain (WWF) with which they are considering The strategies for conservation and dissemination of the state of seabed platforms in Mediterranean waters

OAMMS-1 CRUISE, RV GARCÍA DEL CID

  • Cruzado, Antonio
  • CSIC - Unidad de Tecnología Marina (UTM)
OAMMS-1 Cruise (29GD20090309) carried out on the Research Vessel García del Cid in 2009, Observation, Analysis and Modelling of the Mediterranean Sea(OMMS).The main objective is to consolidate a system of observation of the Mediterranean Sea through the real-time measurement of a number of meteorological and oceanographic magnitudes with a moored buoy, complemented by periodic visits with a research vessel to the mooring site and assimilation of the observations obtained in order to carry out the systematic forecasting of sea conditions in the NW Mediterranean Sea.Six-monthly visits from the R/V Garcia del Cid will be performed at the mooring site and at a grid covering parts of the Catalan Sea. On-deck inspection and maintenance of the instrumentation on the buoy will be carried out. The system was equipped with: a. Positional (GPS, ARGOS transmitter) and meteorological sensors (radiation, wind direction and speed -2 units-, air temperature -2 units-, relative humidity and air pressure). b. Sea surface sensor (temperature, salinity) and ADCP downward looking current meter. c. Underwater sensors -2 units- (depth, temperature, salinity, dissolved oxygen, fluorescence, turbidity, photosynthetic active radiation –PAR-). d. Data logging (Campbell Scientific) and system control. e. transmitting (two-way GSM modem connection) to the shore The proposed research project also aims at consolidating an observational system based on the CEAB multiparametric buoy, equipped with meteorological and oceanographic sensors for real time measurement and transmission to shore of the atmospheric and marine conditions. The buoy will be moored from the B/O García del Cid at a fixed point in the catalan coast, at the head of the Blanes canyon. Automatic observations will be complemented by a series of visits with the CEAB boat to the station where the buoy is moored in order to gather water and plankton samples. At the same time, the present procedure will be improved for the acquisition of water color data (chlorophyll, yellow substance, suspended particles) obtained by the MERIS sensor on board ESA’s ENVISAT satellite. These data offer two levels: 1) real time high spacial resolution files for the western Mediterranean Sea (Levels 1 and 2); and 2) global low to medium spacial resolution (Level 3). The data, together with other historical data also available, will constitute the project database with public access installed in the CEAB server. Limited access will be granted to users in general and, under request, to those with justified scientific or educational interests. A protocol for quality control of the data will be established and followed by statistical analysis in order to provide the models with a sound observational base for their calibration and validation
