GOAL: To observe the Impacts of a long and narrow submarine Canyon on the slope circulation.
The access was conducted by Hydrographic Institute (IH, Portugal) in a way of off-shore mission with a main focus on the area of Nazare Canyon Deep Observatory (Portugal), using an autonomous underwater vehicle SeaGlider (a technology development from University of Washington and currently marketed by Huntington Ingalls Inc. (USA)).
During the mission, the glider collected water column data from EOVs like conductivity, temperature, dissolved oxygen, chlorophyll and turbidity, to depths of 1000 meters. A cross-validation data exercise was conducted with further data obtained from other oceanographic equipment (autonomous moored buoys and ship-based instruments like CTD/Rosette) located in the area, with a main goal to better understand and characterize the hydrographic dynamics of the Nazaré Canyon and surroundings.
