Description

Abundance and distribution of marine infauna in McMurdo Sound, Antarctica, 1988 to 2004.

Methods & Sampling

Sampling and Analytical Methodology:
Benthic fauna were collected by divers in six replicate 0.0075 sq m (0.98 cm diameter) cores. Samples were taken in austral spring (1 November to 10 December). The samples were sieved live on 0.5 mm mesh, fixed in 10% buffered formalin, and preserved in 70% ethanol. Identifications were to species level wherever possible, with the exclusion of large meiofauna (nematodes and harpacticoid copepods). Great care was taken in each step of processing not to lose a single animal; QA/QC procedures included spot check reviews of sample residue, periodic sample recounts, and updating taxonomy as name changes and new species were published in the literature. Locations pre-2001 were determined from shore lineups and are not as accurate as locations post-2001 that were located with GPS.
