Rationale: The main limitation of isotopic tracking for inferring distribution is the lack of detailed reference maps of the isotopic landscape (i.e. isoscapes) in the marine environment. Here, we attempt to map the marine ?13C isoscape for the southwestern sector of the Atlantic Ocean, and assess a...
