An Antarctic ice‐related “superbloom” observed with the MERIS satellite imager
Bibliographic record
Abstract
MERIS (Medium Resolution Imaging Spectrometer) satellite imagery for early March 2006 shows streaks and patches of what appears to be an intense plankton bloom among broken ice off Ronne Entrance, Antarctica, near 73 S, 83 W. The streaks are 2 to 10 km wide and up to 100 km long, extending across open water between land and the ice edge. We interpret these streaks as an example of a previously reported type of “superbloom,” in which very high surface concentrations of chlorophyll occur in water containing ice platelets. Spectral bands of the MERIS satellite imager in the visible and near‐infrared allow computation of an index suitable for detection of surface blooms containing high concentrations of chlorophyll, especially blooms associated with high‐scattering from suspended sediment or ice. The images presented here suggest a new way in which MERIS images can contribute to the study of primary productivity in polar regions.
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.
