Non-tidal sheared turbulent mixing observed in the Halmahera sea
The Indonesian Throughflow (ITF) significantly influences Earth’s climate through turbulent mixing within Indonesian seas. Recent research, utilizing moored current meter data in the Halmahera Sea, reveals that non-tidal sheared turbulence, driven primarily by Internal Gravity Waves (IGWs), dominates below 500 meters – accounting for over 80% of vertical shear. While the Gregg-Henyey-Polzin (GHP) turbulence parameterization accurately models dissipation in the upper 300 meters, its performance degrades deeper, highlighting the need for refined models incorporating IGW characteristics.
What kind of fish(?) is this? North shore Massachusetts
This intriguing specimen, discovered in the rocky intertidal zone off the North Shore of Massachusetts, presents a fascinating identification challenge. While initial searches suggested a flounder, the observed size and morphology warrant further investigation. This small, palm-sized fish represents a valuable opportunity to expand our ocean intelligence—a sentiment echoed in discussions like those surrounding sea creature identification off Ustica Island, as detailed in a related article. We invite expert analysis to definitively classify this unique find and contribute to a broader understanding of coastal biodiversity.
