| Summary: | 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. 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. The purpose of the study was to investigate the movement of organochlorine compounds from the sea-ice into seawater and air during melt |
