Observations of Ringed Seal (Phoca hispida) in the Nearshore Waters of the Chukotka Peninsula
Bibliographic record
Abstract
Despite the importance of ringed seals in the regional economy of the Chukotka Autonomous District, with the end of the commercial fishery, research on the ringed seal in Russia has almost completely ceased. The coastal zone of the Chukotka Peninsula, where the Native people hunt for seals, has seen very little research. This paper is devoted to the study of the modern distribution and habitat of the ringed seal (Phoca hispida) in the coastal waters of Chukotka. Observations of ringed seals were carried out simultaneously with observations of other species of marine mammals from posts located on the coast of the Chukotka Peninsula in 1993 – 96, 1998 – 2000, 2002 – 05, and 2010 – 11. Field studies provided information on the spatial and seasonal distribution, movements, and relative abundance of the ringed seal in the coastal zone. In winter, seals were found on the drifting ice in the southern coastal area of the northern part of the Gulf of Anadyr, and on fast ice and its edge in the bays of the eastern part of the Chukotka Peninsula. In spring, the main aggregations of ringed seals were observed on fast ice in Senyavin Strait, Lavrentiya Bay, and Tkachen Bay. The migration of immature seals to the Chukchi Sea was noted. In summer, animals were distributed in the coastal zone of the entire Chukotka Peninsula, but their relative number decreased by 85%. In late autumn, the main aggregations of seals were observed on the young ice of Lavrentiya Bay, in Senyavin Strait, and in Tkachen Bay. The landfast ice of the eastern coastal zone of Chukotka Peninsula is one of the main areas for the reproduction of ringed seals in the Bering Sea.

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; a candidate call from one teacher head, not a consensus.
