Marine High Resolution Records of the Last Interglacial in Northwest Europe: A Review
Bibliographic record
Abstract
The last Interglacial in Northwest Europe (the Eemian) corresponds to stable oxygen isotope substage 5e (ca. 130-115 ka BP). Foraminiferal studies from northern Denmark suggest that déglaciation after the Saalian Glacial (stage 6) occurred gradually over a period of about 3000 years. Data from borings on the island of Anholt show that the déglaciation was interrupted by a climatic fluctuation equivalent to the Allerod-Younger Dryas-Preboreal cycle at the Weichselian-Holocene transition (stage 2/1). The environmental interpretation of the foraminiferal data when compared to that of the deep sea stable isotope stratigraphy indicates that this climatic oscillation may have been a global event. An initial sea level rise of about 50-60 m occurred at the Saalian-Eemian transition (stage 6/5e at about 130 ka BP) and the assemblages indicate that the sea level rose further in the middle part of the Eemian prior to a gradual drop in sea level in the Late Eemian. The Eemian/ Weichselian boundary (stage 5e/5d at about 115 ka BP) was characterized by a major sea level drop and a temperature decrease from lusitanian to boreal conditions. The final change to fully glacial conditions did not occur until the Early-Middle Weichselian transition (stage 5/4 at about 74 ka BP).

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.
