Subsurface investigations of Marine Plain - Environmental photos taken during projectEntry ID: ASAC_2400_Photos
35 Days were spent in ASPA 143 (Marine Plain, Vestfold Hills, East Antarctica) conducting non-invasive geophysical surveys. Surveys included 11 electrical resistivity soundings, 5 electrical profile lines (each 0.9-1.4 km long), 6 seismic refraction shots (using a hand-held hammer impact as an energy source) and 4 TEM surveys (a non-invasive electro-magnetic technique). In addition, ... total station surveying of all sites, and GPS surveying of selected sites was undertaken. Surface sediment samples were collected from 12 locations within Marine Plain (on geophysical survey sites - i.e. potential coring locations for the 2004/05 season). Expeditioners were Dr Dan Zwartz and Ms Jane Edgar.
The environmental impacts for the 2003/04 field season were as predicted. Footprints and evidence of foot traffic were temporarily apparent along geophysical survey profile lines. Foot travel was minimised and areas of soft sediment were avoided where possible. Walking to and from site was generally along rock outcrops on the eastern and western boundaries of Marine Plain. Helicopters were used to transport equipment and were landed in permitted locations.
Minor disturbance was created around sampling sites. Sediment samples were recovered from shallow, hand-dug pits, with soil placed on plastic tarpaulins. The holes were back filled in the same stratigraphic order, the surface recontoured and rocks repositioned in the orientation they were found.
Photographs were taken of selected sites (geophysical profile lines and sediment sampling sites) before and after disturbance. Sites of previous research interest were also visited and photographed to assess the rehabilitation of the Marine Plain surface. A log was kept of daily activity, recording activity undertaken and personnel involved.
This dataset is a collection of environmental photos taken to record human impacts that have occurred in the area. An excel spreadsheet, detailing each of the photos, is included in the dataset.
