Surface areas of seabed within the 500 m isobath regions within the South Shetland Islands (Subarea 48.1)
Abstract / Description:
Bathymetric maps of two major areas within the South Shetland Islands were generated using several integrated bathymetric databases. These areas comprise the lower South Shetland Island chain from King George Island to Smith Island, and the region around Elephant Island. From the integrated datasets, areas of seabed within the 500 m isobath for six levels of depth strata (0-50 m, 51-100 m, 101-200 m, 201-300 m, 301-400 m and 401-500 m) were computed. Areas were calculated based on planar and interpolated surface area of seabed incorporating seafloor slope. Differences in calculated seabed areas from previous studies were likely due to both improved methodology and georeferencing of contours.
