Emma Cameron on "Depth-dependent influence of Greenland’s fjords on predicted submarine melt rates" - when extrapolating offshore thermal forcing into fjords, above 200m use a fjord model or near-glacier obs, but below 200m offshore water properties are more robust (in the absence of sills)! #igsoc

.@colinrmeyer.bsky.social: FirnLearn, a neural network firn model. Trained separately for different regions. In Greenland, especially, it does quite well & better than current model (which works oddly well). Improves with more observations - and could be used to drive future sampling, too? #igsoc

Omar Faruque: Causal inference for analyzing drivers of GrIS melt. Air temp & precip > various melt impacts. Large-scale variability (NAO) reduces clouds and increase melt. From 9 causal links, 4 agree with domain knowledge at some time lag, but 5 don't. Need to consider more feedback loops. #igsoc

Maya Maciel-Seidman models Greenland runoff using Transfer Learning. Trained on MAR at emulator stage & then fine-tuned using in-situ runoff. Albedo is an important input. TL is most effective in areas where MAR is most biased, but it may be overfit in certain catchments. More tuning data! #igsoc
