Abstract
Data are reported on the amphipods and isopods taken in a sledge-type hyperbenthos sampler in the subtidal of the Voordelta, a shallow coastal area and the Westerschelde, the last true estuary of the delta area (SW Netherlands). More than 300 samples were collected between 1988 and 1991. Two salt marshes in the brackish part of the estuary were sampled monthly with a flume net in 1990 and 1991. A total of 46 amphipod species (42 gammarideans, 3 caprellids and 1 hyperiid), 19 of which are new for the area were recorded. The dominant amphipod species in the Voordelta and the marine part of the Westerschelde estuary are Atylus swammerdami and Gammarus crinicornis. Estimated densities of both species are high comparison to these estimated from macrobenthos samples taken in the same area. This suggests that an important part of the population swims above the bottom and is subsequently overlooked in benthos surveys using only grabs or corers. Some amphipod species that had not been previously recorded from the area were found to be quite common inhabitants of the hyperbenthal.The dominant species in the brackish part of the estuary are Corophium volutator, Gammarus salinus, Pleusymtes glaber and Bathyporeia species. In the salt marshes the same species are dominant but densities are much higher than in the main estuarine channel. Gammarus zaddachi is only present in the salt marshes. The only abundant Isopoda are Idotea linearis in the Voordelta and Paragnathia formica, Eurydice pulchra and Lekanesphaera rugicauda in the salt marshes. From a total of 8 species, there were no new records for the study area.

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.
