Introduction

This data report summarizes information collected during July 2003 near Green
Cabin, northern Banks Island, Canada as part of the NSF-sponsored "Biocomplexity
of Frostboil Ecosystems" project (grant #OPP-0120736). It also includes
information about a halfday visit to Mould Bay on Prince Patrick Island (2 July
2003).
