Figure 1

(A) Map of Antarctica showing ice streams and downstream (floating) ice shelves. The dashed lines in the continental interiors demarcate drainage areas of the East and West Antarctic Ice Sheets that converge into Ross Sea. The gray shade shows the paleo-Bindschadler Ice Stream drainage area during the LGM. B = Bindschadler Ice Stream; D = David Glacier; Byd = Byrd Glacier; M = Mercer Ice Stream; W = Whillans Ice Stream; K = Kamb Ice Stream; Ma = MacAyeal Ice Stream; E = Echelmeyer Ice Stream; CF = calving front; RIS = Ross Ice Shelf; GL = grounding line; RFIS = Ronne-Filchner Ice Shelf; LIS = Larsen Ice Shelf with the darker blue area showing the extent of the Larsen Ice Shelf that collapsed in 2002. The modern-day shelf edge position is shown as a dashed line. (B) Bathymetry of the eastern Ross Sea continental shelf. The paleo-BIS was confined to the WDB between the Hayes and Houtz Banks. The light gray rectilinear lines are the locations of seismic data. The squares are core acquired by Mosola and Anderson24 and the crosses are those described by McGlannan et al.18.
