Lake Joyce field area for study. (A) Location of Lake Joyce in the McMurdo Dry Valleys, Antarctica (inset). (B) Bathymetric model of Lake Joyce as described in the text, along with compilation of drill hole sites, shorelines from aerial photographs and satellite images from the Polar Geospatial Center, and reconstructions of subglacial topography. Arrow marks the site of the drill hole where CTD cast in Figure 2 was conducted. Streams J1 to J5 follow nomenclature of Green, Angle, and Chave (Citation1988). Topographic contours from REMA are ellipsoidal height rather than orthometric height (Howat et al. Citation2022). -- Arctic, Antarctic, and Alpine Research
