Communications Physics, 9(1), 193. https://doi.org/10.1038/s42005-026-02653-0 Nonlinear resonant interactions have long been theorized as the mechanism that moves energy across scales in ocean wind waves, but direct evidence of these processes in the open ocean has remained elusive. Here, the authors use a stereoscopic system to provide experimental evidence of resonant interactions in ocean wind waves, confirming theoretical predictions such as the famous Phillips' figure-eight.

- [Meso-submesoscale surface temperature-salinity compensation and density gradient variability in the North Atlantic from Saildrone observations](https://www.whoi.edu/the-10-km-thermohaline-transition-detected-by-saildrone/): Figure 1. The 10-km thermohaline transition: where salinity takes control of ocean density. Saildrone autonomous vehicles crossing the North Atlantic in 2019 (top left) revealed a fundamental shift in what controls ocean density. Maps (top right) show three distinct regimes sampled: the winter Gulf Stream (GS-Winter, blue), summer open ocean (NAOcean-Summer, red), and fall continental shelf waters (NAShelf-Fall, green). Spectral analysis (bottom panels) shows median (a) and mean (b) Turner angle (Tu) and density ratio (Rρ) across spatial scales. At large scales (>100 km), temperature dominates density structure across all regimes; the ocean "weighs" water primarily by how warm it is. But near the ~10-km submesoscale and approaching the 28-km Rossby radius (Rd, vertical dashed line), a dramatic transition occurs: salinity begins to control density. This crossover is sharpest in temperature-dominated winter Gulf Stream waters (blue), where Tu drops from π/3 to near π/4 at 10 km, but remains gradual in salinity-stratified shelf waters (green).
