Brief communication: A technique for making in situ measurements at the ice–water boundary of small pieces of floating glacier ice

Johnson, Hayden A.; Glowacki, Oskar; Deane, Grant B.; Stokes, M. Dale

This paper presents an apparatus and associated methods for making direct in situ measurements of the ice–water boundary of small pieces of floating glacier ice. The method involves approaching ice pieces in a small boat and attaching a frame with instruments on it to them using ice screws. These types of measurements provide an opportunity to study small-scale processes at the ice–water interface which control heat flux across the boundary. Recent studies have suggested that current parameterizations of these processes may be performing poorly. Improving understanding of these processes may allow for more accurate theoretical and model descriptions of submarine melting.
