The cruise departed from La Reunion Island, and visited Madagascar, the French territories of Mayotte, Crozet, and Kerguelen, and returned to La Reunion. During this cruise, we surveyed marine birds and mammals across a large-scale gradient of ocean productivity and water mass characteristics, spanning from tropical to Antarctic waters (from 12 to 60 degrees S).
