Stratigraphy, environment and climate of the mid Cretaceous succession from the Arctic region (Baffin Bay)
Bibliographic record
Abstract
The super greenhouse climate of the middle Cretaceous represents an analogue for an extreme CO2 induced (run-away) climate system. In order to improve the understanding of how the high northern latitudes responded to the escalating middle Cretaceous warmth we analysed dinocysts, palynofacies, δ13C and various biomarker proxies through a unique mid Cretaceous succession from the northern Baffin Bay. Our study is based on a several sites that were cored during the IODP Expedition 344S. The composite section represents a nearly complete Albian - Turonian succession deposited during the syn-rift phase separating Greenland from Canada/North America. Depositional environments range from anoxic outer shelf and pro-delta fringe to oxygen-restricted lower delta front. The organic geochemical proxies are focusing on the OAE 2 and will investigate changes in the sea surface temperature and water column oxygenation related with this event.
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.

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.
