Spanish contribution to the International Argo Ocean Observation Program.
The main objevtive of the FAUCES 1 bis is the identification of the rececent morphosedimentary feaures of two submarine canyons in the Albroan sea , Guadiaro and Garrucha. To achive this general objetive, we adquire data with the TOPAS system and the mulbeam bathimetry.
Multidisciplinary cruise: Sampling physical and chemical variables that will: - Study thermohaline characteristics, kinematics, dynamics and biology of the eastern half of the Gulf of Cadiz - Establish relationships between climate, hydrology and hydrodynamics and the early stages of development of the species associated with the platform. - Provide data to feed global and regional numerical models. - Generate and distribute a database for the evolution of the marine climate and its resources.
The objective of the project RADIALES, started in 1990, aims at “understanding and modelling the response of the marine ecosystem to the sources of temporal variability in oceanographic and planktonic components, focusing on those factors and processes affecting biological production and potentially altering the ecosystem services”. This project is the oldest multidisciplinary ocean observation initiative still active in Spain.
Make the underwater archaeological chart of the coast of Murcia.
This cruise continues with the line started in previous years cruises with the general operational target of the registration of oceanographic parameters and obtaining water samples and various types of suitable and sufficient plankton for the achievement of the following specific objectives: 1-Determine the influence of the hydrographic scenario on the structure, distribution and condition of larval populations of large and medium pelagic in the Balearic Sea, with special attention to Atlantic bluefin tuna 3-Evaluate the reliability of predictions of such models based on the historical data series available to date. 2-Expand the database for the development of habitat models for laying of the target species, both models based on data taken in situ by hydrographic profiles 4-Calculate a Larval Index for the estimation of the biomass of the reproductive stocks of the genus Thunnus in the Balearic Sea. 5-Improve knowledge about growth, trophic ecology (predator predator interactions) and the genetic structure of larval populations of bluefin tuna and related species in the Balearic Sea. 6- Improve the knowledge of the processes that determine planktonic productivity in the Balearic Sea 7-Improve the intercalibration of quantitative sampling carried out with various plankton samplers.
The goals of this survey are framed within the educational activity of the Faculty of Marine Sciences ULPGC to give the possibility of a complete oceanographic study (Physical , Chemical , Biological and Geological Survey ) in the south and north-east of Gran Canaria students of Degree, Bachelor and Master , the convergence zone between the area and the trail of the island and the presence of permanent rotation south of it. Thus this survey will contribute to a comprehensive training for students in oceanographic study of an oceanic region may Determine the structure of water bodies, the effects of convergence and divergence to the passage of the Canary Current across the channels between islands, mass transport , and nutrients. Determine the distribution of chemical species , including oxygen and carbon dioxide system and quantify the transport of CO2 in the atmosphere-ocean study area , the effect of micro and mesoscale phenomena in their distribution. To characterize the effect of the wake , turns and other mesoscale structures in the distribution of species of phytoplankton and zooplankton.
The main objective of the project VULcanology CAnaria submariNA, VULCANA, is to study from a physical-chemical, biological and geological point of view submarine volcanoes and hydrothermal systems active or not in the entire Canary basin. In addition, special attention will be paid to the continuity of the studies carried out in the Tagoro submarine volcano on the island of El Hierro, continuing, with one of the longest physical-chemical-biological time series in Spanish territory. The specific objectives of the Vulcana1118-ROV campaign will be: 1. Visualization and sampling around the anchoring carried out during the previous campaign (Vulcana-II-0318). The physical-chemical anchor will recover by autonomous pathways with acoustic release. If these techniques fail, the ROV will be used to completely recover the reinforced concrete block with all its sensors from inside the main crater of the Tagoro submarine volcano, at a depth of 127m. 2. Realization of a uniform regular mesh over the entire Tagoro volcanic building with the ROV for the realization of a complete map of the hydrothermal vents. Physical-chemicalbiological and geological samples of the interior of each of these points will be collected with the use of ROV arms and specifically designed samplers (pressure bottles with on / off valves, inverted funnels, mini-ctds, micro- thermal sensors, etc). 3. Placement and collection of physical instruments in test phase on active hydrothermal environments (areas with physical sensors in self-contained and with automatic release capacity - Kaust). The writing of some task related to this objective would be missing in the established format (objective, methodology, responsible researcher, institution, etc.). 4. Continue monitoring studies of the only active submarine volcano in the degassing phase of Spanish territory, Tagoro underwater volcano, on the island of El Hierro.
Historical series of oceanographic data in the Vigo Estuary and adjacent platform.
The goals of this campaign are framed within the objectives of the overall project 'Radial Profunda de Canarias', being the experimental cruise of the proposal. Thus, this cruise will help to: • Determine the structure of the current when it reaches the Canary Islands, of the Outcrop Current and the polar counterflow of slope in its passage through the Canary Archipelago and the African slope, stimating its mass transport, heat and nutrients. • Characterize the different modes of variability of heat and mass transport in easternorth atlantic subtropical gyre and the oucrop in northwest African coast. • Characterize the annual cycle in the physical conditions of the surface layers and mixture to where the seasonal cycle is significant, relating it to the meteorological forcings. • Characterization of changes in water masses, mainly in the North Atlantic Central Water (NACW), in Antarctic Atlantic Intermediate Water (AAIW) in Mediterranean Water (MW), bottom waters of the Canary Basin and the oucrop in northwest African coast, in based on temperature, salinity, nutrients and oxygen. • To characterize the zooplancton and micronecton deep communities. • To charactereze the microbian and heterotrophic communities.
