Spatial and temporal abundance and size trends in scyphozoan jellyfish in coastal Icelandic waters in 2008
Bibliographic record
Abstract
Scyphozoan jellyfish in Icelandic waters have received limited attention, despite apparent recent increases in jellyfish blooms and considerable regional oceanographic and climatic changes. We studied the species composition, abundance, phenology, and growth of scyphomedusae around the island and explored changes in distribution, species composition, and seasonality by comparing our findings with reports from the 1930s. Scyphomedusae were collected with a Bongo net (60 cm ring diameter, 250 cm net length, and 500 µm mesh size) in the top 10 m of the water column in five regions (fjords between 64 and 66°N) around Iceland in the spring, summer, and autumn of 2008. Between 4 and 36 tows were performed per sampling region. This dataset includes umbrella diameter, dry and wet mass, as well as abundance data of two species: Aurelia aurita and Cyanea capillata.
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.
