The background colors indicate annual ice velocity (m/yr) (Rignot et al., 2017). The inset on top left shows the location of the main map with respect to Antarctica. Events are located both on the ice shelf and near major glaciers and ice streams. (b) Vertical waveforms of four highly similar seismic events recorded at station S020, located at Ice Stream E (also known as MacAyeal Ice Stream). Waveforms were filtered between 5 and 30 Hz to highlight the arrivals. Yellow and red vertical lines mark the estimated P and S arrivals (from EQTransformer), respectively. Vertical axis labels show the start of each waveform in Coordinated Universal Time, and horizontal axis time is with respect to the start of the plot. The event locations and short tS−tP&lt;0.5  s indicate that these events are cryospheric, that is, icequakes. The color version of this figure is available only in the electronic edition.

(a) Ross Ice Shelf (RIS‐DRIS) deployment of broadband seismographs during November 2014–November 2016, with some stations recording as late as February 2017 (Bromirski et al., 2015). Black and red stars indicate 200 and 100 samples per second continuously recording stations, respectively. The yellow star indicates central station DR10 near the Yesterday Field Camp. Geographic data are from Fretwell et al. (2013). The inset in right represents ice shelf morphology from Haran et al. (2018) showing source regions of high‐amplitude ice shelf seismic events (red dots within elliptical regions) from Chen et al. (2019), including events near DR14 associated with intrashelf rift WR4 (Olinger et al., 2019). KPDR is a pressure‐sensor equipped ocean‐bottom seismograph installed contemporaneously with the network (Chen et al., 2019). Inset in the left represents degree of ice shelf stability critical buttressing estimated by Furst et al. (2016), with the (red) boundary transition also reproduced on the main figure.

Conceptual diagram showing inferred evolution of the Garwood Valley paleolake and deltas. Dates are derived from ages in Table 4. (A) Garwood Valley during interglacial time. The Ross Ice Shelf (white) sits offshore, floating on the Ross Sea (black). (B) Expansion of the East and West Antarctic Ice Sheets during the Pleistocene thickens the Ross Ice Shelf, grounding it to form the Ross Sea ice sheet (white). (C) Continued growth of the Ross Sea ice sheet thickens the ice sufficiently to flow up-valley from the coast and into Garwood Valley, transporting the up-valley till with it (bold). (D) A period of ice-sheet stability allows ice in the upper reaches of the valley to sublimate and deflate slightly, while a resurgence of ice expands into the mouth of the valley, transporting the down-valley till atop it (bold). Up-valley till formation occurred at least 25.8 k.y. B.P., because it underlies the oldest dated carbonate beds, and the down-valley till is at least as old as 14.1 k.y. B.P. because reworked sediment from it is present in the middle delta. (E) The ice dam in the mouth of Garwood Valley blocks flow of the paleo–Garwood River forming a proglacial lake that superposes the up-valley till (UVT) and buried ice. (F) The upper delta forms in the ice-dammed lake. (G) Retreat of the Ross Ice Shelf grounding line south of Garwood Valley strands a portion of the ice dam in the valley. Thermokarst erosion of the ice dam (dashed line) results in lowering of lake level and deposition of the middle delta. (H) Continued ablation of the ice dam results in lowering of lake level and deposition of the lower delta.
