Data for benthic polchaetes (retained on a 300 micrometer seive) collected in megacores from the FOODBANCS 1 project. During FOODBANCS 1, megacore samples were collected and sorted during five cruises (1999-2001) to 3 stations along the West Antarctic Peninsula shelf. The project and data collection are described in Smith et al. (2008), Glover et al. (2008) and Neal et al. (in prep.).
