International audience RATIONALE: The main limitation of isotopic tracking for inferring distribution is the lack of detailed reference maps ofthe isotopic landscape (i.e. isoscapes) in the marine environment. Here, we attempt to map the marine δ13C isoscape forthe southwestern sector of the Atlanti...
