Enabling Under Ice Glider Operations: A Backseat Driver Approach
Journal of Field Robotics, Volume 43, Issue 5, Page 3292-3311, August 2026.ABSTRACT Polar Oceans are key locations for forcing global ocean circulation, influencing both global climate and biogeochemical cycles. Due to restricted access to these seasonally and perennially ice‐covered regions, these areas are severely undersampled.

Antarctic summer sea ice concentration and extent: comparison of ODEN 2006 ship observations, satellite passive microwave and NIC sea ice charts [PDF]
The Cryosphere, 2009 Antarctic sea ice cover has shown a slight increase (<1%/decade) in overall observed ice extent as derived from satellite mapping from 1979 to 2008, contrary to the decline observed in the Arctic regions.

Environmental Research Letters, 2021 Winter precipitation estimations and spatially sparse snow observations are key challenges when predicting snowmelt-driven floods. An improvement in streamflow prediction is achieved in a snowmelt-dominant basin, i.e.

Earth and Space Science, Volume 13, Issue 8, August 2026.Abstract Snow on Antarctic sea ice modulates albedo, thermodynamic growth, and snow–ice formation, yet remains a leading uncertainty in altimetry‐derived sea‐ice thickness. Here we use the post‐2022 CRYO2ICE configuration to derive along‐track winter snow thickness from ICESat‐2 laser and CryoSat‐2 Ku‐band radar freeboards over the Weddell and Ross ...

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 4, August 2026.Abstract Snow on sea ice modulates the Earth's radiation budget and sea ice mass balance, yet satellite retrievals of Arctic snow depth remain subject to substantial algorithmic uncertainty. We develop a multi‐model machine learning (ML) framework for retrieving spring snow depth over Arctic sea ice from Advanced Microwave Scanning Radiometer 2 (AMSR2).

Retrieval of Surface Air Specific Humidity Over the Ocean Using AMSR-E Measurements
Sensors, 2008 We have developed a new algorithm to estimate the surface air specific humidity over the ocean from AMSR-E data. It should be noted that remarkably reduced random errors of the estimated surface air specific humidity result from using the surface air ...

Increased Frequency, Duration, and Area of Winter Polynyas North of Greenland in a Warming Climate
Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.Abstract Polynyas play a crucial role in the polar marine ecosystems and climate system. Four winter polynya events north of Greenland have been observed, but the response of winter polynyas to climate warming remains unknown. This study investigates projected changes in winter polynyas in the Wandel Sea north of Greenland using the AWI‐CM3 climate ...

Invisible Ship Tracks Produce Mean‐State Cloud Microphysics Perturbation in Tropical Trade Cumulus
Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.Abstract Aerosol effects in cumulus‐topped boundary layers remain relatively unconstrained and drive uncertainty in climate modeling. We assess the impacts of shipping aerosol on trade cumulus, combining satellite retrievals and large eddy simulations (LES).
