Paleoceanographic records in the Chukchi Basin, western Arctic Ocean during the late Quaternary
Bibliographic record
Abstract
在西方的北极海洋的晚第四级的 paleoceanographic 变化被有孔虫目的丰富的量的研究揭示，冰木排岩屑( IRD )并且它的矿物学并且 petrological 作文， planktonic Neogloboquadrina pachyderma (罪恶)( Nps )- 18O 并且- 13C ，在从 Chukchi 盆的核心 M03 标志的源於生物、非源於生物的部件在第二中国国家北极远征期间航行。七个 IRD 事件出现在 MIS 7， 5， 3 和 1。这些 IRD 在巨大的冰山被带，它通过 MClure 海峡冰溪流被出口到博福特海，加拿大的北极群岛，然后由博福特旋回搬运了进 Chukchi 盆。低 IRD 免职在更延长冰盖子并且削弱了博福特旋回的冰川的时间期间发生了，当开的水条件和加强的博福特旋回在间冰期的时期期间赞成了 IRD 免职时。因此， IRD 事件不仅显示更粗糙的岩屑和冰出口事件的起源，而且反映博福特旋回和北美的冰表的进化历史。七轻 Nps- 18O 并且 - 13C 旅行能对海冰形成导致生产并且同位素地轻的盐水下沉的提高的率作出回应，但是与温暖的大西洋水和淡水输入无关。而，重 Nps-18O 并且 - 13C 价值独立反映减少的北极淡水，和平的水，和通气得好的表面从大陆人架和 halocline 水流水。 CaCO3 内容和 planktonic 的变化当分别地，全部的器官的碳( TOC )和蛋白石内容在冰川、间冰期的时期期间增加了并且减少时，有孔虫目的丰富能在间冰期、冰川的时期期间表明大西洋水的增长或减少的输入它能与 TOC 降级，蛋白石溶解和在底部水和沉积之间的接口的氧化还原作用条件有关。

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.
