British Antarctic Survey, 2024. Bedmap3 - Bed topography of Antarctica - Side 2, 1:10,000,000 scale map.
BAS Thematic Map Series, Sheet 3B, Edition 1. Cambridge, British Antarctic Survey.
Abstract:
This is side 2 of a double-sided map. The map showcases Bedmap3, the latest suite of gridded products
describing the surface elevation, ice-thickness and the seafloor and subglacial bed elevation of Antarctica
south of 60°S. Bedmap3 incorporates and adds to all of the post-1950s datasets previously used for Bedmap1
and Bedmap2, including 84 new aerogeophysical surveys by 15 data providers that represent an additional 52
million data points and 1.9 million line kilometres of measurement.
Side 2 shows ice catchments, subglacial lakes beneath the ice and the drainage network of rivers and hydrology
that drains meltwater from the interior of the continent to the ocean. The lakes are a mixture of active and
permanent lakes identified from surface features and radio echo sounding. The catchments and hydraulic
potential flow lines are modelled from Bedmap3 data. Note that not all water accumulations in the modelled
data will be true lakes.
Purpose:
This is side 2 of a double-sided map. The map showcases Bedmap3, the latest suite of gridded products
describing the surface elevation, ice-thickness and the seafloor and subglacial bed elevation of Antarctica
south of 60°S.
