Abstract

fetched live from OpenAlex

Abstract The distribution of global fallout radionuclides in Indian Ocean waters about four decades after their main injection from atmospheric nuclear weapons tests on the ocean surface is discussed. Recent data obtained in the framework of the WOMARS (Worldwide Marine Radioactivity Studies) and SHOTS (Southern Hemisphere Ocean Tracer Studies) projects are evaluated and compared with previous investigations carried out in the northern and southern Indian Ocean. The results indicate transport of surface waters labeled with radionuclides from the Mediterranean Sea, as well as from the Northwestern Pacific through the Indonesian Seas to the Indian Ocean. After passing the equator the waters circulate in the South Indian Ocean subtropical gyre, which accumulates radionuclide tracers and other contaminants on timescales of decades. This accumulation of contaminants in the Southern Indian Ocean is of environmental importance for the protection of the marine environment from land‐based contamination sources.

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.

Not 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.
