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

Hayden Allen Johnson, Oskar Glowacki, Grant Biden Deane, and Malcolm Dale Stokes

Abstract. This paper presents a method for making direct in-situ measurements of the ice-water boundary of floating growlers. The method involves approaching floating growlers in a small boat and attaching instruments to the growlers 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.

Short summary
This paper is about a way to make measurements close to small pieces of floating glacier ice. This is done by attaching instruments to the ice from a small boat. Making these measurements will be helpful for the study of the physics that goes on at small scales when glacier ice is in contact with ocean water. Understanding these small scale physics may ultimately help improve our understanding of how much ice in Greenland and Antarctica will melt as a result of warming oceans.
