Abstract

fetched live from OpenAlex

Abstract-The fugacity of CO * (fCO2) and the content of chlorophyll a in surface-water were determined during consecutive sections between 47 ” and 60”s along 6”W in austral spring, October-November 1992. In the Polar Frontal region, the fC02 of surface-water decreased from slightly below the atmospheric value to 50 patm below it. This was accompanied by the development of diatom blooms. Seasonal warming of 1.2”C and air-sea exchange partly compensated the decrease of fCOz by biological activity. Meanders of the Polar Frontal jet and a mesoscale eddy were reflected in spatial variability of fCO2 and chlorophyll a. Systematic observations indicated relationships between fCOz and chlorophyll a, albeit changing with time. The combination of biological C02-uptake with formation of Antarctic Intermediate Water (AAIW) makes the Polar Front a site of combined biological/physical COZ-drawdown from the atmosphere. In the southern part of the Antarctic Circumpolar Current (sACC) and the Southern Frontal region, fCOz increased 7-8 patm due to surface-water warming of OYC. A sharp rise of surface water fC02 of 13 patm occurred south of the southern Frontal jet. As the ice-cover disappeared, the Boundary between the ACC and the Weddell Gyre released significant amounts of CO*. The Weddell Gyre would become a strong COz-source after the imminent retreat of the ice. Clearly mechanisms

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.
