delta-C-13, delta-N-15, and C/N were measured for each of 247 muscle tissue samples from 12 bird, 4 seal, and 4 fish species collected in the Weddell Sea primarily during March 1986. delta-C-13 values ranged from -31.3 to -22.0 parts per thousand and, in the case of fish and seal samples, varied inversely with C/N. This implied that lipid concentration significantly influenced these vertebrate delta-C-13 measurements. No such relationship was found between C/N and delta-N-15, where the latter values ranged from +4.4 to +11.2 parts per thousand. with considerable overlap among many of the taxonomic groups measured.
