Auckland soil geochemical baseline
Bibliographic record
Abstract
Maps and quality assurance and quality control (QAQC) data of trace element concentrations in soil from the Auckland Region. Point source and interpolated maps of trace element concentration in soil samples taken over the Auckland Region are included for three depths: O-depth (0-2 cm); A-depth (2-20 cm); B-depth (50-70 cm). Trace concentrations for 65 elements were measured via ICPMS undertaken at Bureau Veritas Mineral Laboratories, Vancouver, Canada. A 0.5 g split of each sample was digested in 10 ml of 1:1:1 HCl-HNO3-deionized H2O aqua regia solution in glassware for one hour in a hot water bath. Five percent HCl was used to return each sample to a standard 10 ml volume post-heating. The entire sample set was run consecutively, in batches of 40, on a single machine to minimise time-dependant variation, using a PerkinElmer ELAN 9000 ICPMS instrument. In total 487 samples were run [336 unknown samples and 151 samples for QAQC].
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.
