The nodal cycle in coastal sea level records
Sea level rise will become a huge challenge for coastal societies around the world. We need good data, we need good models, and we need to understand all changes.

Modeled Greenland Ice Sheet evolution constrained by ice-core-derived Holocene elevation histories
Abstract During the Holocene, the Greenland Ice Sheet (GrIS) experienced substantial thinning, with some regions losing up to 600 meters of ice. Ice sheet reconstructions, paleoclimatic records, and …

Failure strength of glacier ice inferred from Greenland crevasses
We uncover a new failure criterion for ice using a large dataset of greenland crevasses. Abstract Ice fractures when subject to stress that exceeds the material failure strength. Previous studies have …

The influence of inter-annual temperature variability on the Greenland Ice Sheet volume
Temperature variability in the forcing of the ice-sheet model affects both the Greenland Ice Sheet equilibrium volume and its transient response to instantaneous changes in temperature. Abstract The …

Episodic Subglacial Drainage Cascades Below the Northeast Greenland Ice Stream
The presence of water flowing beneath the Greenland Ice Sheet impacts the friction exerted on ice flowing from inland to marginal regions, potentially affecting the rate of sea level rise by …

The Transient Sea Level response to external forcing in CMIP6 models
The planet is warming, and sea levels are rising as oceans expand and ice on land melts. The warmer the Earth gets, the faster the seas will rise. Projecting future sea level rise (SLR) using …

FEniCS on windows
FEniCS is a really nice tool for finite element modelling in python. It is difficult to install FEniCS on windows. The official instructions use a docker image. which I think is a bit heavy handed. I …

Modeling enhanced firn densification due to strain softening
Ice becomes more less viscous when it is being strained. It is a power law fluid. Therefore firn densifies faster in shear margins. In this paper we show how existing firn densification models can be …
