This study investigates the role of atmospheric dynamics in sea-ice thickness and snow depth at a coastal site in East Antarctica using in situ measurements and numerical modeling. The snow thickness variability is impacted by atmospheric forcing, with significant contributions from precipitation, Foehn effects, blowing snow, and episodic warm and moist air intrusions, which led to changes of up to 0.08 m within a day for a field that is in the range of 0.02–0.18 m during July–November 2022.

 This study demonstrates that snow cover generally suppresses crop growth (GPP) in Northeast China's croplands through thermal effects.  Snow cover generally exerts a negative effect on GPP through the thermal influence. Regionally, snow indirectly inhibits GPP via water-mediated effects in the Liaohe and Songnen Plains, but promotes it in the Sanjiang Plain, Xing'an and Changbai Mountains, and Western Sandy Area.

When water moves through a catchment it is affected by interaction with soil particles and groundwater. For this interaction to occur the water must move through the ground, something that is restricted by ground ice in permafrost landscapes. Here we look at the interplay between hydrology, water-age, and water chemistry in a catchment in West Greenland, and even if the permafrost leads to short flow paths and young water-age, there is considerable interaction between water and soil particles.

Glacial lakes are often dammed by moraines, which can fail, causing floods. Traditional methods of measuring moraine dam structure are not feasible for thousands of lakes. We instead developed a method to measure moraine dam movement with satellite radar data and applied this approach to the Imja Lake moraine dam in Nepal. We found that the moraine dam moved ~90 cm from 2017–2024, providing information about its internal structure. These data can help guide limited hazard remediation resources.

We produce annual maps of Antarctic surface melt volumes from 2012 to 2021 using satellite microwave data. We detect melting days from thresholds on the satellite signal and then use actual melt measurements from weather stations to convert those signals into water‑equivalent volumes. Our maps capture known melt hotspots and show slightly lower totals than climate models. This dataset supports climate and ice‑shelf studies.

We devised two simple models for estimating the mean annual permafrost table temperature and active-layer thickness, which are driven solely by temperatures measured in the active layer; no ground physical properties are required. The models showed deviations of less than 0.05 °C and 9 %, and can therefore be useful tools for permafrost modelling under a wide range of environmental conditions.

Icebergs ground when they reach shallow topography such as Bear Ridge in the Amundsen Sea. Grounded icebergs can block the transport of sea-ice and create areas of higher and lower sea-ice concentration. We introduce a physically and observationally motivated representation of grounding in an ocean model. In addition, we improve the way simulated icebergs respond to winds, ocean currents, and density differences in sea water. We analyse the forces acting on freely floating and grounded icebergs.
