Short summary
Short summary
By simulating a section of the Scandinavian Ice Sheet over a deep fjord, we aim to understand the behaviour of ice sheets over rough landscapes. For perpendicular flow, we find reduced speed within the fjord and reverse flow at its base. Comparing real and smoothed topography shows that low-resolution models fail to capture these effects. Our findings have implications for Greenland ice sheet models, as commonly used bedrock resolutions likely overlook the influence of similar rough landscapes.

Sentinel-2 images are subject to distortion due to orthorectification error, which makes it difficult to extract reliable glacier velocity fields from images from different orbits. Here, we use a complete record of velocity fields at four Greenlandic outlet glaciers to empirically estimate the systematic error, allowing us to correct cross-track glacier velocity fields to a comparable accuracy to other medium-resolution satellite datasets.

To better understand how snowfall in East Antarctica changes over time, we reconstructed annual snow accumulation from the Mount Brown South ice core over the last millennium. The record shows significant variability across time scales, including multiple centennial-length periods with much less snowfall than observed in the satellite era. Our results raise implications for assessments of future sea level rise.

Short summary
Accurate modelling of calving is a major problem that leads to uncertainties in sea-level rise. By modelling calving as a random process and testing how this interacts with water flow beneath the glacier, we show that including this water flow is essential to be able to fully reproduce real calving in a computer model. This may help guide future ice-sheet models as to how to improve their existing representations of Greenland and Antarctica.

Lakes at glacier margins can drain beneath the ice in sudden, devastating, floods called jökulhlaup. We present the first 2D model of jökulhlaup propagation, first applying it to a synthetic glacier, before then assessing its ability to reproduce an observed record of lake fill-drain cycles in Greenland. Our results match a 17-year record of flood timing but underpredicts peak discharge likely because we are missing certain physical processes. Our results hold promise for simulating jökulhlaup.

Short summary
Our research delves into the future evolution of Antarctica's Wilkes Subglacial Basin (WSB) and its potential contribution to sea level rise, focusing on how basal melt is implemented at the grounding line in ice flow models. Our findings suggest that these implementation methods can significantly impact the magnitude of future ice loss projections. Under a high-emission scenario, the WSB ice sheet could undergo massive and rapid retreat between 2200 and 2300.

We present cost-effective photogrammetric systems for high-resolution rockfall monitoring. The paper outlines the components, assembly, and programming codes required. The systems utilize prime cameras to generate 3D models and offer comparable performance to lidar for change detection monitoring. Real-world applications highlight their potential in geohazard monitoring which enables accurate detection of pre-failure deformation and rockfalls with a high temporal resolution.

Short summary
This study presents a database compiling 95 ice temperature profiles from the Greenland ice sheet and peripheral ice caps. Ice viscosity and hence ice flow are highly sensitive to ice temperature. To highlight the value of the database in evaluating ice flow simulations, profiles from the Greenland ice sheet are compared to a modeled temperature field. Reoccurring discrepancies between modeled and observed temperatures provide insight on the difficulties faced when simulating ice temperatures.

Short summary
Unmanned Aerial Vehicles (UAVs) are increasingly common tools in the geosciences, but their use requires good ground control in order to make accurate georeferenced models. This is difficult in applications such as glaciology, where access to study sites can be hazardous. We show that a new technique utilising on-board GPS post-processing can match and even improve on ground-control-based methods, and, as a result, can produce accurate glacier velocity fields even on an inland ice sheet.
