Figure 1: Study area of Prydz Bay and surrounds.
From: The suppression of Antarctic bottom water formation by melting ice shelves in Prydz Bay
Bathymetry from ETOP01 (http://www.ngdc.noaa.gov/mgg/global/global.html) with 250 m contour intervals. Major geographical features shown include Prydz Bay, Prydz Channel and the Four Ladies Bank, with the Amery and West Ice Shelves. Coastal polynyas are also shown using satellite-derived sea ice production estimates (dark green contours show 5 ma−1) from ERA-Interim data (1992–2014)14,15: Cape Darnley, MacKenzie Bay, Davis and Barrier Bay. Mean fast ice contours37 are shown as thick light blue contours. Instrumented mooring locations M3, M4 (ref. 10) and PBM7 are shown with red squares. Inset: large-scale bathymetry of Southern Indian Ocean (45–72° S) across the Antarctic margin (30–100° E) with elephant seal data locations from Davis Station deployments (red and magenta points for 2011 and 2012, respectively) and an Iles Kerguelen deployment (green points from 2013). Black box indicates the location of the study area shown.
