Abstract
This was the first of two cruises, the overall objective of which was to undertake an integrated baseline environmental survey of the continental slope west of Shetland. The major objective of this cruise was to obtain TOBI (30 kHz) and 100 kHz sidescan sonar imagery of the designated survey area west of Shetland. All the objectives of the cruise were achieved in full or exceeded. Over 14000 km2 of seafloor was imaged with the TOBI system during 25 days of survey and 650 line km of 100 kHz data were obtained in 3.5 days of survey. Twelve sample stations were occupied during trials of the multicorer, box corer and Day grab. As anticipated, the mapped sediment facies variations are strongly related to waterdepth. Iceberg ploughmarks dominate the seafloor structure to depths of about 500 m. At mid slope depths, sediment bedforms and erosion due to current activity can be seen. At greater depths, less energetic depositional conditions prevail. Highlights of the sonar survey include the discovery of a field of barchan sand-dunes at a waterdepth of 300 m, a small sediment slide at 900-1000 m waterdepth, and an extensive sandy contourite sheet between the 850 and 1000 m depth contours between 61° and 61°20’N. The second cruise of the two cruises, mainly devoted to seabed sampling, is described in Southampton Oceanography Centre Cruise Report No. 7.

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; the direct Gemma label and the distilled Codex classifier agree on what is shown here.
