This study examined meiofauna community composition along a 5500 km region of the Western Antarctic. The objectives of this project was to (1) examination of large- and small-scale variation in meiofauna community composition, (2) determination of whether any taxa, represented as operational taxonomic units (OTUs), were found along the whole geographic range sampled, and (3) determination of how sediment nutrient profiles correlate with meiofaunal community composition within this geographic region.
