All scientific data collected by the Australian Antarctic program (AAp) are eventually described in the Catalogue of Australian Antarctic and Subantarctic Metadata (CAASM). CAASM can be used to search through AAp data descriptions, and it also provides links to access publicly available datasets, which can either be immediately downloaded or obtained from the Australian Antarctic Data Centre (AADC).

Description

Marine macrofaunal invertebrate community composition data from 30 sites sampled by divers around Davis Station, East Antarctica, for the Davis Sewage Treatment Project during the 2009/10 summer.
Soft-sediment infauna were sampled using a core of PVC tubing (15cm long x 10cm diameter) pushed 10cm into the sediment. Lids were placed on the top and, after some digging, on the bottom of the core and the sealed core was extracted from the sediment. In the lab, core contents were rinsed through a 0.5mm sieve and the remaining infauna and other material preserved in 8% buffered formalin in seawater with Biebrich Scarlet stain (4 cores per plot) or 96% ethanol (1 core per plot). Infauna were sorted from the surrounding matrix under a binocular microscope, counted and identified to species, when possible, or allocated to a morphospecies category.

Purpose

To assess the impact of sewage discharge on marine macrofaunal communities close to (potentially impacted) and at various distances away from (control) the discharge point at Davis Station.
