Cartography of sea beds off Spanish cities

Spain: AZTI-Tecnalia presented the cartography for the sea beds off the coast at the Basque cities of Donostia-San Sebastián and Bilbao. This is high precision and high quality material which will be of great use to fishing sector as well as leisure ones, such as scuba diving, surfing or recreational fishing. The project was financed by the Department of the Environment, Land Planning Territorial, Agriculture and Fisheries of the Basque Government, Spain.

The project aims at mapping the entire continental shelf located off the Basque coast, detailing the most salient points such as rocky outcrops, underwater canyons or shipwrecks. The study was undertaken by the Area of Operational Marine and Oceanographic Dynamics of AZTI-Tecnalia. The maps corresponding to other enclaves of the shelf will be published shortly. AZTI-Tecnalia has posted a survey on the www.itsasnet.com Web portal. All the maps can be acquired on https://tienda.azti.es/.

The cartography of the Bilbao geographic zone encompasses the interior continental shelf comprising the stretch from El Covarón to Barrika and, in the case of Donostia-San Sebastián, the sea bed of the coastal city’s municipal limits.

AZTI-Tecnalia researchers used Multibeam Ecoprobe in their study. This technology enables, by means of various acoustic pulses, the reproduction of the topography of the sea beds in the zone under investigation with a wide-ranging and very high definition.
