ECS Awardee 2023: The interactions between ice, sea level and the solid Earth in Antarctica and their global impacts
Bibliographic record
Abstract
<!--!introduction!--><b></b> Marine sectors of the Antarctic Ice Sheet are prone to runaway retreat in a warming climate with global consequences. Observation and modelling-based studies suggest that these sectors have collapsed in the past and have the potential to contribute significantly to sea-level change in coming centuries, but the extent and timing of ice loss remains uncertain. Constraining ice cover changes in Antarctica is challenging because the solid Earth, water and ice systems are strongly linked, and key processes are often buried under the ice and take place on a range of spatiotemporal scales. To complicate matters, modern measurements of these systems contain a large signal from glacial isostatic adjustment (GIA) due to past ice mass changes, but Earth structure beneath areas of active ice sheet retreat in Antarctica is characterized by significant lateral variability, making the GIA signal challenging to constrain. This talk will summarize a progression of work bringing together the fields of glaciology, climate science and solid Earth geophysics to characterize the interactions between ice, sea level and the solid Earth in Antarctica and their implications for past and future global sea-level changes.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
