Transit Cartagena-Las Palmas-Salvador de Bahía
This equipment trials cruise has provided opportunities for test and verification of technology under development at the Proudman Oceanographic Laboratory (POL), the Scottish Association for Marine Science (SAMS) and the National Oceanography Centre, Southampton (NOC,S). This includes equipment developed during the first year of funding under OCEANS 2025 (theme 8). Testing technology in the ocean environment is invaluable in assessing fitness for purpose. Specifically, the cruise tested: A Spar wave buoy (NOC,S) biogeochemical sensors (NOC,S); an UAV system (NOC,S); a video grab system "HyBis" (NOC,S), A benthic Multicore (NOC,S), A benthic lander and associated torroidal Telemetry buoy (POL), and a shallow tow towfish (POL). Testing in Spanish waters (near Tenerife, Gran Canaria and Fuerteventura) has been invaluable. The time on passage has been minimised (the transition from deep to shallow water is less than a days steaming) and the calm conditions to the southwest of the islands in the consistent prevailing north easterly winds have enabled deployment and recovery techniques to be tried and optimised in safety.
Monthly survey to study thermohaline and biological characterization of water masses in the East-North Atlantic.
CANAL IX
Study of the impact of the 'bowling train' fishing modality on the seabed of the Cantabrian Sea.
Abundance indices, distribution patterns and faunal assemblages of demersal species in the Porcupine bank, together with the possible driving factors of their distribution. This survey belongs to the research project: ?Evaluacion de Recursos Demersales por Metodos Directos en el Area ICES?. This Project is partly funded by the DCR of the EU and the Education and Science Spanish Ministery.The main objectives of the above mentioned project related with this survey time series are: a) to obtain abundance indices of the main exploited species in the Porcupine bank; b) to estimate the strength of yearly recruitments of these species and their distribution in the bank. c) to study the structure and distribution o the demersal and benthic communities in the area.
