Study of different sectors of the Mediterranean margins of Andalusia to analyze the potential existing active tectonic structures, capable of generating geological risks either due to the generation of earthquakes, or secondarily due to the triggering of landslides and / or tsunamis.

1. To obtain estimates of Nephrops burrows densities in the Gulf of Cádiz from a randomized isometric grid of UWTV stations spacing 4 nautical miles using the underwater images. 2. To define the Nephrops distribution in the Gulf of Cádiz 3. To obtain density estimates of bentho-demersal macrofauna species 4. To calibrate bentho-demersal macrofauna observed in the underwater videos and those obtained in the beam trawl. 5. To obtain and the occurrence of trawl marks on the sea bed 6. To measure oceanographic variables using a sledge mounted CTD 7. To collect sediment samples 8. To prospect circalittoral and bathyal areas without trawling activity 9. Sea bed morphological and backscatter analyses

The campaign targets under TASIFE 0414, to carry on board the research vessel Angeles Alvariño, are the set up and maintenance of equipment deep underwater photography TASIFE 2013. Specific objectives focus on the investigation of benthic Banks areas of 'Reserva Marina de La Palma' and 'ZEC Franja Marina Teno-Rasca (Tenerife)' by direct and visual methods. Specifically: · Extensive visual videogrammetry HD with sled towed "NEXUS". · Recognition with multibeam bathymetric probe.

The campaign targets under TASIFE 0415, to carry on board the research vessel Angeles Alvariño, is the assessment of the state of the benthic epifauna in the vicinity of the volcanic eruption of La Restinga. Specifically: • Direct sampling of rocks and epibenthic macrofauna benthic dredge drag. • Making extensive HD images with Observation Vehicle Towing TASIFE 2013.
