“Visions in Ice”

The glittering blue interior of an ice cave sparkles in this award-winning image by photographer Yasmin Namini. The cave is underneath Iceland’s Vatnajokull Glacier. Notice the deep scallops carved into the lower wall. This shape is common in melting and dissolution processes. It is unavoidable for flat surfaces exposed to a melting/dissolving flow.

schematic / flow chart - Schematic showing the Bedmp3 source datasets (white boxes) combining to make intermediate products (blue boxes) and ultimately the final set of grids (orange boxes) and their uncertainties (yellow boxes). Note that the surface grid has a uniform estimated uncertainty (Section Uncertainty estimates).

maps - Bedmap3 grids of (a) bed topography and (b) surface elevation, in metres above sea level (g104c geoid), and (c) ice thickness in metres. Locations labelled in (b) are referred to in the text

The BedMachine v3 bed has some subjective advantages over Bedmap3 where glacier flow is relatively fast, but survey data are sparse. (a) Surface flow speed43; (b) BedMachine v3 bed topography; (c) Bedmap3 bed topography, both overlaid on shaded relief and with survey data shown as grey lines. The black dotted line highlights a trough under slow-flowing ice that is more smoothly continuous in Bedmap3. The white oval highlights the trough of a relatively fast-flowing ice stream that in BedMachine v3 is more smoothly streamlined and subjectively more realistic than in Bedmap3, given the typical streamlined form of deglaciated ice stream landscapes. An objective test of bed accuracy in this area requires more survey data.

maps - The Bedmap3 survey dataset allows us to calibrate the more continuous and extensive freeboard-based ice shelf thickness grid. (a) Pointwise ice thickness biases between 119,000 survey measurements and the freeboard-derived ice thickness grid47 on the Ross Ice Shelf, showing coherent patterns of bias; (b) these pointwise offsets median-filtered over a 20 km radius; (c) spline-interpolated calibration grid of the filtered offsets in (b); (d) bias-corrected version of the freeboard-derived ice thickness grid after subtraction of the calibration grid in (c).

https://doi.org/10.1016/j.jag.2025.104371 <-- shared paper
--
HIGHLIGHTS:
• Proposed U-ViT model based on Prithvi GFM for multi-sensor glacial lake mapping.
• Achieved an F1 score of 0.894 on Sentinel-1&2, surpassing CNNs scoring below 0.8.
• Maintains strong performance with 50% less training data, proving efficiency.
• Excels in detecting small lakes (<0.01km²) and handling clouds and complex terrains..."

maps and chart - Spatial map of southern Weddell Sea with summer (DJF) climatology and anomalies for sea ice concentration (SIC; a–d), zonal wind (e–h), and ocean surface stress curl (i–l).

Overview map of the Filchner Trough region in the eastern part of the southern continental shelf in the Weddell Sea. The bathymetry is from IBCSO (Arndt et al., 2013) with marked contours every 100 m. Grounded ice is shaded dark gray and floating ice shelves are light gray. Mooring locations are marked with colored circles, historic CTD casts with gray dots, and the deployment location of the APEX floats as diamonds. Red and blue arrows are a sketch of the circulation of relevant water masses, mWDW and ISW, respectively. The inset in the upper left shows the location of the study site.

maps and charts:
(a) Velocities from the moorings averaged within 0.1°C temperature bins
(b) Temperature (according to colorbar) along the float trajectories of Fst (brown diamond, through the Small Trough), Fsill (green diamond, along the eastern flank), and Fcs (purple diamond, within the Filchner Trough) at their parking depths of 400, 400, and 250 metres, respectively.
(histograms) temperature bins within the temperature ranges of ISW and mWDW.

“Lively”

In “Lively,” filmmaker Christopher Dormoy zooms in on ice. He shows ice forming and melting, capturing bubbles and their trails, as well as the subtle flows that go on in and around the ice. By introducing blue dye, he highlights some of the internal flows we would otherwise miss. (Video and image credit: C. Dormoy)
