Progress Code: completed Statement: The dates provided in temporal coverage are approximate only. The years are correct. Ten sediment cores were collected from 3 marine bays in the Windmill Islands. Two cores were collected in Sparkes Bay, one in Shannon Bay, and seven in Brown Bay. Only diatom data are presented here, however Pb210 and metal analyses have also been undertaken - contact Ian Snape ([e-mail]) for more information regarding this. The diatom spreadsheet (diatom_data) lists the relative abundance of benthic species. The abbreviation used to identify species are explained in the separate file called sp_list. Each core has been saved as a separate file. The STE cores were collected from within a couple of meters of each other. These cores were collected in close proximity to a tip site at one end of Brown Bay. BBMid was collected from the middle of the bay, while BB Outer 1 and 2 were collected from the outer regions of this bay, and thus represent the greatest distance from the tip site. Unless otherwise stated, the lowest number within each core represents the youngest sample. This work was completed as part of ASAC project 1130 (ASAC_1130) and project 2201 (ASAC_2201). Public summary from project 1130: Algal mats grow on sea floor in most shallow marine environments. They are thought to contribute more than half of the total primary production in many of these areas, making them a critical food source for invertebrates and some fish. We will establish how important they are in Antarctic marine environments and determine the effects of local sewerage and tip site pollution. We will also investigate the impact on the algal mats of the additional UV radiation which results from the ozone hole. Public summary from project 2201: As a signatory to the Protocol on Environmental Protection to the Antarctic Treaty Australia is committed to comprehensive protection of the Antarctic environment. This protocol requires that activities in the Antarctic shall be planned and conducted on the basis ...
