​Cover: In Santibanez et al. (, image taken in January 2019 shows accretion ice that formed on the bottom of the West Antarctic Ice Sheet where it flows over Subglacial Lake Mercer, Antarctica. The ice-lake water interface is located 1092 m beneath the surface of the ice sheet. The clear accretion ice is located in the upper right section of the image and the lake water in the lower left section. The scale is approximately 20 cm across. The image was taken with the ROV Deep Scini by Bob Zook and John Winans of the SALSA Science Team with support from the National Science Foundation.
