Abstract

Planktic foraminifer tissue d15N from net tows in the Sargasso Sea (off Bermuda) in the western subtropical North Atlantic. Net tow samples from 0-200 m at BATS (31°40’N, 64°10’W) and Hydro Station S (32°10’N, 64°34’W), collectected on R/V Atlantic Explorer cruises HS1178, B274, AE1203, B280, B283, AE1220, B287, B292, B295, B299.
