Abstract

fetched live from OpenAlex

A refraction/wide-angle reflection seismic experiment consisting of three lines in the Nares Strait region between Ellesmere Island and northwest Greenland was carried out from August 6 to September 8, 2001, as part of a multidisciplinary program. The overall objective of the program is to provide new information on the origin of Nares Strait and shed insight on the controversy over its development. To run the experiment in the ice-choked waters, Canada=s largest icebreaker, the CCGS Louis S. St. Laurent, was required along with two ship-based helicopters. The main refraction/wide-angle seismic line was located between Makinson Inlet on Ellesmere Island and Thule Air Base in Greenland. Initial analysis of the seismic data shows a clearly defined high-amplitude Moho reflection with a lateral correlation of >150 km. Crustal thickness on the eastern end of the line (Greenland) is estimated to be approximately 35 km using a simple one-dimensional velocity structure.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not 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.
