Abstract

fetched live from OpenAlex

Abstract The temporal changes in dissolved inorganic (DIC) and organic carbon concentrations (DOC) were monitored from late autumn to spring 2006 in the Scholaert Channel, West Antarctic Peninsula. Surface DIC spanned a small range (2163.3 to 2194.5 μmol kg -1 ), increasing from late autumn to winter and then decreasing in spring. An excess of DOC (7.0–63.6 μmol l -1 ), against a deepwater background concentration of 44 μmol l -1 , existed in the surface mixed layer throughout the sampling period. Mass-balance budgeting indicates that the DIC dynamics were primarily governed by remineralization in winter and by primary production in spring despite very low biomass of both autotrophic and heterotrophic organisms. The net community production (7.3 mmol C m -2 d -1 ) in spring was mainly partitioned to DOC accumulation (3.6 mmol m -2 d -1 ) and downward export of particulate organic carbon (POC) (2.9 mmol m -2 d -1 ) rather than POC accretion (0.8 mmol m -2 d -1 ) in the surface mixed layer. The study area acted as a source of CO 2 to the atmosphere in winter (∼0.8 mmol m -2 d -1 ) and a sink in spring (2.3–5.3 mmol m -2 d -1 ), and hence was not a one-way CO 2 sink as had been previously hypothesized for marginal sea ice zones.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
