Bibliographic record
Abstract
The project ReBELS (Resolving Biological carbon Export in the Labrador Sea) is funded by the UK Natural Environmental Research Council (NERC) and aims to understand and quantify the transport of oceanic organic carbon into the deep sea and its effect on ocean carbon storage. To do so, we proposed to set up a year-long ocean observatory in the Labrador Sea using state-of-the-art autonomous observing technologies (gliders and biogeochemical ARGO floats) paired with traditional measurements of carbon flux (moored sediment trap) to understand the different contribution of particle injection pumps to the overall carbon export in the Labrador Sea. This cruise will collect all assets. JC268, is the first of three cruises which set up this year-long observatory in the Labrador Sea. The cruise comprised several goals: - Deploy a mooring, containing 3 sediment traps, physical and bio-optical sensors, acoustic doppler current profilers and current meters and 2 FluxCams (custom-made camera system aiming at characterising the sinking speed of particles). - Deploy 2 BGC-Argo floats, one of them contributing to the BGC-Argo Network and a second one, the ReBELS float, fitted with specialty sensors to characterise particles (UVP6), the upper ocean phytoplankton community (hyperspectral radiometer) and estimate carbon flux (optical sediment trap, transmissometer). - Conduct physical and biogeochemical measurements to validate/calibrate the deployed assets and create a baseline and understanding of the physical and biogeochemical drivers of carbon export. - Conduct opportunistic measurements at the GOSNAP mooring lines around Greenland to validate sensor measurements, in particular oxygen sensors recently fitted on the array. The cruise consisted of 4 main stations: 1. CTD line off Nuuk; 2. mooring; 3. Floats deployment; 4.GOSNAP mooring array.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot 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.
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; both teacher heads agree on what is shown here.
