Abstract

fetched live from OpenAlex

The upper ocean is home to several hydrodynamic instabilities which are known to generate strong vertical flows crucial for the transport of physical and biochemical properties. Here we study the two-dimensional Ekman-Inertial Instability (EII), the analytical description of which is currently limited to one dimension, and compare its effects with those of Inertial Instability (InI). We found that EII grows significantly faster and creates stronger vertical flows than InI. Moreover, we explore the sensitivity of its growth rate to variations in the Rossby number of the initial flow. We found that EII and InI radiate near-inertial waves that propagate in regions of anticyclonic vorticity.

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.
