Short summary
Tidewater glaciers play a central role in polar dynamics, but their study is limited by harsh and isolated conditions. Here, we introduce broadband echosounders as an tool for the study of high-latitude fjords through the rapid collection of calibrated high-resolution, near-synoptic observations. Using a dataset collected in Hornsund Fjord, we illustrate the potential of broadband echosounders as a relatively accessible, low-effort tool, well suited for field deployment in high-latitude fjords.
