SPATIAL AND TEMPORAL PATTERNS OF NET CARBON EXCHANGE IN THE POLAR SEMI-DESERT VEGETATION TYPE ON MELVILLE ISLAND, NUNAVUT (2013)
Bibliographic record
Abstract
In 2013, eight Automated Soil CO2 Exchange (ACE) Stations were deployed at the Cape Bounty Arctic Watershed Observatory (CBAWO) to quantify the contribution of CO2 exchange from polar semi-desert vegetation. The polar semi-desert vegetation type is of specific interest as it is widely distributed across the High Arctic and there are relatively few studies conducted in the past on its contributions in CO2 exchange. As polar semi-desert vegetation cover varies at relatively small spatial scales, the chambers were distributed between vegetated areas (18-51% cover) and bare soil. The measurements from each chamber were automatically recorded every 30 minutes from May 30 2013 to July 28 2013. Air temperature, soil temperature and soil moisture measurements were also collected in conjunction with the net CO2 exchange rate (NCER). The collected results indicate that respiration is the dominant process of CO2 exchange during the early season, while photosynthesis is the dominant component during the warmer part of the season.

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.
