GREC is totally independent from governmental organizations. GREC has organized, or formally participated to, numerous boat surveys in: - western and eastern Mediterranean - north eastern Atlantic - French Polynesia - French West Indies Most of the surveys were carried out in a 'combined visual/acoustic' mode, with a towed hydrophone. GREC members are authors or co-authors of more than 30 scientific papers. EcoOcéan Institut is a non-governmental organization, with professional researchers working in the north-western Mediterranean Sea on cetaceans, turtles and seabirds since 1994. Campaigns at sea are dedicated to data collection (marine animals, maritime traffic, marine debris) and the research methods used are mainly "line transect" and "photo-identification."

Both 1996 and 1997 surveys include acoustic material. Contact Groupe de Recherche sur les Cétacés for information on these data. Currently, only cetacean sightings have been included in OBIS-SEAMAP, but the full dataset includes seabirds, sea turtles and sunfish, along with the effort tracks. Contact EcoOcéan Institut for these data. Additional references: Gannier A., Drouot V. & Goold J.C., 2002. Distribution and relative abundance of the sperm whale in the Mediterranean Sea.

Groupe de Recherche sur les Cétacés shares data with partner researchers on the basis of 'dear colleague' agreements. EcoOcéan Institut contributes to the growing knowledge on vertebrates of the Mediterranean Sea aiming for their protection. We work on subjects like ecology, distribution, and monitoring the impact of human activities (bycatch, ship strike, disturbance by leisure vessels). We also work with marine protected area managers and decision makers at a local, national or international level notPlanned Nathalie Di-Méglio EcoOcéan Institut Primary contact ecoocean@wanadoo.fr http://www.ecoocean-institut.org/ Alexandre Gannier Groupe de Recherche sur les Cétacés Primary contact a_o.gannier@sfr.fr www.cetaces.org NA NA NA Nathalie Di-Méglio owner Alexandre Gannier owner NA zd_1426 2025-09-11T15:38:36-04:00 dataset Gannier, A. and N.
