Short summary
Short summary
Ephemeral grounding sites appear as ice shelves thin or sea levels rise. Sentinel-1A/B imagery (2014–2023) tracked these sites on Pine Island Ice Shelf, noting their disappearance after a 2020 calving event. Basal melting directly influences these sites, while calving and atmospheric forces are indirect factors. This site could become a key pinning point, impacting future calving. Further modeling is needed.

Short summary
Short summary
This paper uses sequential daily SAR images covering the Robeson Channel to quantitatively study kinematics of individual ice floes with exploration of wind influence and the evolution of the ice arch at the entry of the channel. Results show that drift of ice floes within the Robeson Channel and the arch are both significantly influenced by wind. The study highlights the advantage of using the high-resolution daily SAR coverage in monitoring sea ice cover in narrow water passages.

Short summary
A long-term time series of ice sheet surface elevation change essential for assessing climate change. This study presents a 30-year monthly 5 km gridded surface elevation time series for the Greenland Ice Sheet from multiple satellite radar altimeters. The dataset can provide detailed insight into Greenland Ice Sheet surface elevation change on multiple temporal and spatial scales, thereby providing an opportunity to explore potential associations between ice sheet change and climatic forcing.
