This dataset contains example data collected during the development of a method to make in-situ measurements at the ice-water boundary of floating growlers. The method involves attaching instruments to the ice with ice screws and a modular structure of tubes and clamps. There are three types of data included: 1) Temperature measurements made using a custom-built array of thermistors that was positioned orthogonal to the ice face; 2) video of the ice face in which bubbles in the ice and rising through the water are clearly visible; and 3) acoustic data recorded with a hydrophone placed a few centimeters from the ice face. The video and acoustic data were collected simultaneously. The data presented here are intended primarily as a demonstration of feasibility. This type of data provides an opportunity to study sub-meter scale processes that occur at vertical boundaries of glacier ice and fjord water in the field. Improving understanding of these processes is important for understanding submarine melting at ...
