Abstract

fetched live from OpenAlex

Four surface sediment samples in the area of Chukchi Sea were collected,then the total sugar(TCHO) and total carbon(TC) of the samples were detected.The values are in the range of 0.094%~0.154% and 0.95%~2.17%.Associating with TOC,TN,TP,and isotope analysis,the results show that the main source of organic substance in Chukchi Sea is marine phytoplankton.On the other hand,we choose a core sample to detect the same parameters in its different depth.TCHO and TC were positively correlated.This indicates sugar is one of the fundamental components of the carbon in the samples.In addition,the peak appears in the surface sediment sample.Our research also indicates that the distribution of sugar and carbon in the core samples is connected with the action of surrounding ocean currents.A clockwise ocean currents in Canada Basin carry terrestrial substance through the region,resulting in the stations in the surrounding environment with a lot of terrigenous organic matter in marine sediments.

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.
