| Summary: | Progress Code: completed Statement: The ice extraction unit pump failed during collection. Attempts were made to use another pump, however this impacted the quantitative nature of the results. (Metadata editor) - care should be taken with these data, as precise sample locations, or collection dates have not been provided. Purpose The purpose of the study was to investigate the movement of organochlorine compounds from the sea-ice into seawater and air during melt 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.
