This paper reports on the operational experience using a Slocum underwater glider in mouth of the Ilulissat Fjord, Western Greenland. The goals of this year's deployment were to determine the feasibility of using aglider in partially ice-covered waters. We conducted a series of water profiling missions to a depth of up to 150m, revealing some interesting features in the water column. Furthermore the feasibility of using gliders to profile icebergs using an upward looking sonar was partially demonstrated. In the absence of a dedicated ice-profiling sonar the glider's altimeter was modified on site to perform this mission. Both types of missions were successfully concluded, i.e. the glider was retrieved, and gave some valuable insight for future deployments. NRC publication: Yes
