Topic: “The sound of glacial retreat: broadband acoustic characterization of ice-ocean= boundary”

Abstract: The submerged termini of tidewater glaciers are a critical\ , yet poorly characterized component of high latitude regions. The ice-oce an interface act as a conduit for freshwater discharge from terrestrial ic e sheets to the ocean\, both directly via submarine melting and calving an d as the emission location of sub- and supra-glacial runoff. Traditional o ceanographic measurement techniques are limited at glacial termini by dang ers associated with iceberg calving\; remote measurements by active acoust ic systems represent a useful\, if underutilized\, tool to study this crit ical region. This talk will discuss research efforts to characterize the i ce-ocean interface and associated freshwater discharge processes of tidewa ter glaciers based on field data collected in Svalbard in 2023 and 2026. T hese efforts include 1) characterizing the connections between broadband b ackscattering spectra and ice face geometry\, 2) investigating the impact of ice face roughness on backscattering distributions over a range of graz ing angles\, and 3) measuring the geographic extent and scattering mechani sms associated with a subglacial discharge plume.
