Sea ice freshwater budget published in The Cryosphere
Published February 2025, this manuscript uses observations from the 2020 MOSAiC Expedition to compile the first full budget of sea ice freshwater sources and sinks over the summer season in the Arctic. Key findings include: A relatively high fraction (58 %) is derived from surface melt The magnitude and rate of local meltwater production are remarkably…

Maddie was recently interviewed for the U.S. Scientific Committee on Antarctic Research (SCAR) series, in association with her ongoing collaboration with Dr. Steve Ackley through the 2017 Polynyas, Ice Production, and seasonal Evolution in the Ross Sea (PIPERS) expedition. The full interview can be read on the SCAR website.

This week, Maddie and UW graduate student Jake Davis completed deployments of 9 microSWIFT wave buoys over sea ice and ocean near Olikok Point, Alaska. These buoys will collect and send wave data via satellite telemetry, contributing to validation of measurements from seafloor cables as part of an ongoing NSF project, in collaboration with Sandia…
Read MoreNew manuscript on the sea ice thickness distribution in climate models and from satellite published
Our new manuscript recently published in JGR-Oceans suggests the following key findings: Higher resolution of the sea ice thickness distribution increases simulated Arctic sea ice thickness, with little change in Antarctic sea ice. The impact has a larger effect on dynamic processes than thermodynamic processes. Comparison with subgrid-scale thickness observations from ICESat-2 suggests targeting ridging…
