A new Antarctic map, “Bathymetry and Geological Setting of the Drake Passage”, has just been released. This SCAR product represents an international collaborative effort coordinated by the Spanish Geological Survey (IGME) and the British Antarctic Survey (BAS), working together with the Korea Polar Research Institute (KOPRI), the Alfred Wegener Institute (AWI) and the United States Antarctic Program (USAP).
The map covers an area of 1470000 km2 between parallels 52ºS and 63ºS and between meridians 70ºW and 50ºW. The data were collected over the last 25 years on more than one hundred oceanographic cruises onboard six different Antarctic research vessels. This initiative is part of SCAR’s IBCSO (International Bathymetric Chart of the Southern Ocean) Expert Group, which recognises the importance of regional data compilations in Antarctic areas of particular scientific interest. The map has been published by the BAS and the IGME, with support from SCAR through the Geosciences Group.
