Effects of Pack Ice on the Composition of Micronektonic Communities in the Weddell Sea
Using seabirds as sampling devices on two cruises in the northwestern Weddell Sea, we investigated the species and lengthfrequency distribution of micronekton in surface waters. Our micronekton samples are among the first ever collected simultaneously in both ice-covered and adjacent ice-free waters...

Using seabirds as sampling devices on two cruises in the northwestern Weddell Sea, we investigated the species and lengthfrequency distribution of micronekton in surface waters.
