Soil nitrogen availability, CO2 exchange, environmental measurements of a High Arctic wetland across growing season (2016)
Bibliographic record
Abstract
The data set was collected as an ongoing study at the Cape Bounty Arctic Watershed Observatory examining the environmental controls over spatial patterns of soil nitrogen availability in a High Arctic wet sedge meadow and how they influence carbon exchange processes to predict whether this feedback will develop. The goal of the study is to characterize the relationships between plant-available nitrogen and productivity and to see how these relationships are manifested in hyperspectral signatures. These data files contain soil nitrogen availability, carbon dioxide exchange, and environmental measurements of a High Arctic wetland across the growing season. Soil inorganic nitrogen concentrations were measured by ion exchange resin membranes and analyzed using automated flow colourimetry. Net ecosystem exchange and ecosystem respiration were measured using closed, static chambers according to methods in Beamish et al. (2014). Environmental measurements (soil moisture, soil temperature, and active layer depth) were taken twice weekly at site adjacent to the locations of the ion exchange resins.
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.

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.
