A Reanalysis and Reinterpretation of Geodetic and Geomorphologic Evidence of Glacial-Isostatic Uplift in the Churchill Region, Manitoba
Bibliographic record
Abstract
We review the history of analyses of the tide-gauge record for Churchill, Manitoba, and advance a new analysis of the record using a longer time series than that available to Tushingham (1992). The sensitivity of the mean rate of relative sea-level change obtained to the averaging procedure employed is demonstrated by calculating rates for sliding observation intervals of variable widths. After that, the 'best' mean rate of relative sea-level rise is compared with estimates of the mean rate of land uplift and the mean rate of gravity change based on GPS and absolute gravimetry data, respectively. As an additional type of observation, the postglacial relative sea-level change obtained from paleo-shoreline evidence in the Churchill region is also included. Assuming that the governing process is glacial-isostatic adjustment, a joint inversion of the four types of data return upper- and lower-mantle viscosities of about $3 \times 10^{20}$ Pa s and $> 5 \times 10^{21}$ Pa s, respectively.

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.
