Metadata details
AAS_4332_1
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
This data set provides the organochlorine content found in four sea-ice samples collected in the vicinity of Davis station over a three week period in 2014/15. Sea-ice is thought to serve as a reservoir for organochlorine pesticides during the winter. The aim of the study was to investigate the movement of organochlorine pesticides in the seasonal sea-ice during ice melt. A custom made, closed-system, ice melting unit, coupled to an in-situ water filter, was implemented for sampling. Minimal ice-melt or change in organchlorine content was found over the three week period. Changes were attributed to high ventilation of the sea-ice surface caused by high wind speeds found in the Antarctic compared to the Arctic.
4 sea-ice samples were collected in the vicinity of Davis station and contaminant profiles extracted and analysed. Caution should be taken in interpretation of data as the ice/water extraction unit failed during operation.
Purpose
The purpose of the study was to investigate the movement of organochlorine compounds from the sea-ice into seawater and air during melt
Quality
The ice extraction unit pump failed during collection. Attempts were made to use another pump, however this impacted the quantitative nature of the results.
