Abstract:
To understand the drivers and consequences of climate change on timescales important to humans, the paleoclimate of ice cores, the glacial system and local climate patterns were analysed from the Gawn Ice Piedmont Glacier. A GPR/GPS (8, 35, 200 and 500MHz) survey was carried out to provide an image of the internal layering of the glacier and the topography of the ice-rock interface beneath. A 13m firn core was recovered and analysed for oxygen and hydrogen isotope ratios, major cations, anions and methylsulfonates, trace elements and cations, dust concentration and mineralogy.
Description:
The IGS global system of satellite tracking stations, Data Centers, and Analysis Centers puts high-quality GPS data and data products on line in near real time to meet the objectives of a wide range of scientific and engineering applications and studies.
Description:
The ice reader database hosts basic data from ice cores of the Antarctic Continent. The goal is to compile a complete list of cores by name, site, location and as much other information as possible
Description:
Publishing Network for Geoscientific & Environmental Data This database contains information regarding stable oxygen isotopes of snow pits at four sites: Polar Plateau, Victoria Lower Glacier, Wilson Piedmont Glacier and Baldwin Valley Glacier
Quality
The areas were calculated in ArcGIS 10.1 as follows: 1 The bathymetric grid was classified into one hundred metre depth ranges and converted to polygons, with land excluded. 2 The polygons were clipped to the extents of the Marine Reserve and Conservation Zone. 3 Areas of the resultant polygons were calculated using a Lambert Azimuthal Equal Area projection with Central Meridian 75.594 degrees East and Latitude of Origin 51.877 degrees South. 4 The areas were then summarised in a spreadsheet.
