Fig. 1: Modern surface ice velocity and bed topography of the Ross Sea region of Antarctica.
From: Ocean cavity regime shift reversed West Antarctic grounding line retreat in the late Holocene
a Modern ice surface velocity (m/yr) and b bed topography (m above sea level) of the Ross Sea region of Antarctica. Colored circles indicate locations of proxy records, including subglacial sediments (magenta), ice cores (yellow), relative sea level reconstructions (purple), and marine sediments (cyan). Light blue shading indicates locations of polynyas in the Ross Sea. Magenta circles outlined in black indicate the age constraints are from direct measurements, whereas unoutlined magenta circles indicate the age constraints are modeled.
