Essential habitats of key marine species derived from satellite data

The objective of this project is to identify the habitat of key marine species, mainly fish of market value, using satellite-derived data of the sea surface in support of fisheries management and control and/or species protection.

The target species are currently the Atlantic bluefin tuna, the European hake and fin whale in the Mediterranean Sea and the yellowfin and skipjack tuna species in the tropical Atlantic and Indian Ocean. The feeding habitat is derived for all species while the spawning habitat is computed only for tuna species. The period covered is from March 2000 or August 2003 depending on the sensors used to yesterday (near real time).

 

Potential habitat of the Atlantic bluefin tuna which was produced in near-real time (3-day composite, example for May 12-14 2011):

Potential FEEDING habitat of the Atlantic Bluefin tuna integrated over 15 days for 16-31 August 2010:

Potential FEEDING habitat of the Atlantic Bluefin tuna integrated over the years 2003 to 2009:

Potential SPAWNING habitat of the Atlantic Bluefin tuna integrated over 15 days from 2003 to 2011 (16-31 May, mainly the areas in pink):

Potential SPAWNING habitat of the Atlantic Bluefin tuna integrated over 15 days from 2003 to 20011 (1-15 June, mainly the areas in pink):
