Lots of dots! These are spot heights generated for our Air Operations Planning Maps, using REMAv2 2m tiles. Next steps are to clean up the density, add existing GPS points & then add them to our maps, which are used for planning by pilots across the continent. The data will then be openly published!

Observation-constrained calving law for the Antarctic Peninsula: A simple equation (easy to use) yet significant step forward in regional calving model validation. My PhD @rparsons.bsky.social led this work. This is just a start-expect more in the near future!
We have a new paper in the Annals of Glaciology.
We propose a simple parameterisation for calving in ice flow models and also show how modelled calving can be validated using remote sensing data - this is essential in improving confidence in model outputs.

New modelling paper shows that adding an underwater curtain to the fjord of one of Greenland's largest glaciers cannot prevent further retreat under even a low emissions scenario and comes with a plethora of economic and cultural concerns from local indigenous people

Active ice sheet conservation cannot stop the retreat of Sermeq Kujalleq glacier, Greenland - Communications Earth & Environment
Asynchronously coupled ice sheet and fjord modelling suggests that raising the natural sill in Jakobshaven fjord with an artificial barrier could cool the fjord water but not by enough to offset atmos...

Pine Island Glacier accounts for a large proportion of recent Antarctic ice loss. This 7.5 year animation from Sentinel-1 shows the weakening of the lateral margins and the stochastic nature of the calving process. Grab a full-screen version here: aluckman4.wixsite.com/ade-s-world-...
