Colin Jenkinson is not left alone at the WAIS. Ryan Scott eagerly arrived and joined Colin for 5 weeks at the WAIS. They were later joined by Greg Stone in the last week of the mission. While they were there, Colin and Ryan launched 4 sondes per day. Ryan’s additional role was to garner the best dataset they could possibly obtain and gave much attention to instrument calibration, status, sensor hygiene, data back-up, etc. Greg arrived at the end to help strike equipment and to pack and leave.
