Surface areas of seabed within the 500 m isobath for regions within the South Shetland Islands (Subarea 48.1)

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 data sets, 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, 301-400m, 401-500 m) were computed. Areas were calculated based on true surface area of seabed incorporating seafloor slope
