Heard Island glacier fluctuations and climatic change - 2003/04 FieldworkEntry ID: ASAC_2363
Abstract: This report describes the data collected for ASAC project 2363 (a continuation of ASAC 1158). A full report of the data collected and the work completed is available for download with the dataset.
The download file contains data in the following areas:
DEM - Digital Elevation Model
RES - Radio Echo Sounder
This CD contains data collected by the Heard Island glaciology team during the 2003-04 Australian Antarctic Division expedition, as well as some data from the previous expedition in November 2000. The data report associated with these files is provided as a PDF in the Report folder.
Description of data files available on CD
Excel file with the measured height of each survey wand above snow/ice surface for the field season.
Excel file with sonic ranger data for BG35.
Excel file with sonic ranger data for BG50.
Excel file with analyses of chloride, sulphate, nitrate, Mg, Ca, Na of samples collected from crevasses and cores.
Excel file with dO18 analyses of samples collected from crevasses and cores.
ASCII file with the 2003 DEM grid, generated using Golden Software Surfer v7.0. Header file format is:
id The identification string DSAA that identifies the file as an ASCII grid file.
nx nynx is the integer number of grid lines along the X axis (columns)
ny is the integer number of grid lines along the Y axis (rows)
xlo xhi xlo is the minimum X value of the grid
xhi is the maximum X value of the grid
ylo yhi ylo is the minimum Y value of the grid
yhi is the maximum Y value of the grid
zlo zhi zlo is the minimum Z value of the grid
zhi is the maximum Z value of the grid
grid row 1
grid row 2
grid row 3 -these are the rows of Z values of the grid, organized in row order. Each row has a constant Y coordinate. Grid row 1 corresponds to ylo and the last grid row corresponds to yhi. Within each row, the Z values are arranged from xlo to xhi. Blanked grid nodes are given a Z value of 1.070141E+038. Rows are 39.855 m apart, Columns are 40 m apart.
Excel file with all points used to calculate the dem_2003.xls grid (refer to A2).
The folder also contains high resolution jpeg images of Fig. 16 and the data distribution figure (A2).
Lagoon bathymetry folder
Folder containing Excel files with Easting, Northing (acquired using Garmin GPS V; WGS84, UTM zone 43) and depth (acquired using Garmin 'Fishfinder' depth sounder) for each lagoon surveyed. Also high resolution jpeg images of bathymetric maps reproduced in appendix A3.
Contains an excel file with stream profiles and flux calculations, and repeat measurements of Brown Lagoon outflow stream. Also contains jpeg photos of three of the inflow streams, and an image showing their location using the Quickbird satellite image for reference.
Contains jpeg digital photos used in this report.
This data report is reproduced as both a low and high resolution Adobe Acrobat PDF file, for on-screen viewing and printing respectively.
