Rise of the Ellsworth mountains and parts of the East Antarctic coast observed with GPS
Bibliographic record
Abstract
[1] Using GPS observations from 1996 to 2011, we constrain postglacial rebound in Antarctica. Sites in the Ellsworth mountains, West Antarctica, are rising at ≈5 ± 4 mm/yr (95% confidence limits), as in the postglacial rebound model of Peltier, but ≈10 mm/yr slower than in the model of Ivins and James. Therefore significant ice loss from the Ellsworth mountains ended by 4 ka, and current ice loss there is less than inferred from GRACE gravity observations in studies assuming the model of Ivins and James. Three sites along the coast of East Antarctica are rising at 3 to 4 ± 2 mm/yr, in viscous response to Holocene unloading of ice along the Queen Maud Land coast and elsewhere. Kerguelen island and seven sites along the coast of East Antarctic are part of a rigid Antarctica plate. O’Higgins, northern Antarctic peninsula, is moving southeast at 2.3 ± 0.6 mm/yr relative to the Antarctic plate. Citation: Argus, D. F., G. Blewitt, W. R. Peltier, and C.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
