Horizontal and vertical movement data derived from a data storage tag deployed on a single Atlantic cod in the North Sea from 2001 to 2002
Bibliographic record
Abstract
This data is derived from the deployment of a single data storage tag on an Atlantic cod (Gadus morhua) in the English Channel. The cod was tagged in the North Sea on 03/04/2001 and was recaptured in the North Sea on the 06/02/2002. The cod migrates north from the tagging location off Lowestoft, and spends the summer off the north-east coast of the UK, north of the Dogger Bank. The dataset contains 309 days of data, and comprises three files: depth measurements at a 10 minute sampling rate for the full record, depth measurements at a 10 sampling rate for July 2001, and estimates of horizontal position for each day. A description of tag type, fish capture, tag attachment and tag accuracy can be found in Righton et al. (2010). Righton et al. (2010) is published in Marine Ecology Progress Series and is freely available here; [Thermal niche of Atlantic cod Gadus morhua: limits, tolerance and optima][1]. The data storage tag was pre-programmed to record depth (m) at 10-minute intervals for the duration of deployment, and depth at 10s intervals for the month of July 2001. Horizontal movement rates were calculated in a two-step approach. First, daily geolocations were estimated via a Fokker-Planck-based method that combines a tidal location method and a Bayesian state-space model (see Pedersen et al. 2008 for model details).

Righton & Mills (2008) previously used this dataset as part of their work to develop geolocation methods.

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.
