Strategies for the Simulation of Sea Ice Organic Chemistry: Arctic Tests and Development
Geosciences, 2017 A numerical mechanism connecting ice algal ecodynamics with the buildup of organic macromolecules is tested within modeled pan-Arctic brine channels. The simulations take place offline in a reduced representation of sea ice geochemistry.

Optimization of the k-nearest-neighbors model for summer Arctic Sea ice prediction
Frontiers in Marine Science, 2023 The Arctic sea ice plays a significant role in climate-related processes and has a considerable effect on humans, however accurately predicting the Arctic sea ice concentration is still challenging.

Analyzing links between simulated Laptev Sea sea ice and atmospheric conditions over adjoining landmasses using causal-effect networks [PDF]
The Cryosphere, 2020 We investigate how sea ice interacts with the atmosphere over adjacent landmasses in the Laptev Sea region as a step towards a better understanding of the connection between sea ice and permafrost.

Higher-order statistical moments to analyse Arctic sea-ice drift patterns
Annals of Glaciology, 2020 Geophysical systems are often assumed to follow Gaussian probability density functions; however, deviations from Gaussian behaviour can shed light on the underlying dynamics.

Exploring beneath the PIG Ice Shelf with the Autosub3 AUV [PDF]
, 2009 On 31st January 2009, two numbers: “range and bearing” flashing up on a laptop screen, indicated that Autosub3 had returned from its last mission beneath the Pine Island Glacier (PIG) Ice Shelf in the Western Antarctic.

SAR deep learning sea ice retrieval trained with airborne laser scanner measurements from the MOSAiC expedition [PDF]
The CryosphereAutomated sea ice charting from synthetic aperture radar (SAR) has been researched for more than a decade, and we are still not close to unlocking the full potential of automated solutions in terms of resolution and accuracy.

FEBS Letters, EarlyView.The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

Towards ice core sampling by subsea robotic vehicles [PDF]
Geoscientific Instrumentation, Methods and Data SystemsIce coring has developed into one of the most frequently used sampling methods across cryospheric sciences. Sea ice, firn and glacial ice are sampled using a range of different coring systems.

Towards a coupled model to investigate wave–sea ice interactions in the Arctic marginal ice zone [PDF]
The Cryosphere, 2020 The Arctic marginal ice zone (MIZ), where strong interactions between sea ice, ocean and atmosphere take place, is expanding as the result of ongoing sea ice retreat.

FEBS Letters, EarlyView.We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.
