Interpolated bathymetry of Long and Tryne Fjords, Vestfold Hills, Antarctica
Entry ID: long_tryne_bathy


Summary
Abstract: This GIS dataset is the result of the interpolation of bathymetry from depth measurements made in Long and Tryne Fjords in the Vestfold Hills, Antarctica (see Entry: VH_bathy_99). The Topogrid command within the ArcInfo GIS software, version 8.0.2, was used to do the interpolation. Coastline and spot height (heights above sea level) data, extracted from the Australian Antarctic Data Centre's Vestfold Hills topographic GIS dataset (see Entry: vest_hills_gis), was also used as input data to optimise the interpolation close to the coastline. See related URLs for a map showing the interpolated bathymetry.

Quality
The data are intended to provide a general indication of the variation of bathymetry within the two fjords. The number and distribution of depth measurements was limited and so it should not be assumed that accurate depths can be deduced for specific locations from the interpolated data. The input data were interpolated to a raster grid with a 50 m cell size. The horizontal positional accuracy of the depth measurements (determined using non-differentially corrected GPS) may not be sufficient to justify this resolution. However, given the intended use of the product, it was deemed that the use of a 50 m cell size was not inappropriate.
