Abstract Near‐inertial waves (NIWs) are an important source of turbulence for the ocean interior. Mesoscale anticyclonic eddies are known to facilitate their propagation at depth while trapping them. However, in situ observations have so far focused on large (>50 ${ >} 50$ km radius), energetic eddies, whereas most of the ocean is populated by smaller,

Low‐Frequency Ocean Waves Triggered by Tropical Cyclones via Seafloor Distributed Acoustic Sensing
Abstract Propagation of low‐frequency ocean waves, including infragravity (IG) and internal waves, affect ocean dynamics and energy transfer within marine environments. IG waves are long‐period ocean surface waves that can propagate long distances across the ocean and impact the coastlines and deep ocean, while internal waves are buoyancy‐driven ...

Interaction of Ocean Currents and Seamounts: Near‐Bottom Dynamics Around Atlantis II
Abstract This work investigates through a modeling exercise the interaction of a strong, surface current with isolated seamounts, focusing on the Gulf Stream and Atlantis II, one of the New England Seamounts. The roles of bathymetric details and model resolution are investigated with three simulations that consider realistic realizations of the ...

Topographic Scattering of Internal Waves in the Presence of a Steady Surface Current
Abstract Wave–topography interaction is one of the primary mechanisms through which internal wave energy cascades to small length scales, eventually leading to turbulent diffusion and mixing in the oceans. Precise diffusivity parametrizations are crucial for modeling oceanic flows accurately.

Episodic Northward Transport Along Nares Strait Brings Anomalously Warm Water Into the Arctic Ocean
Abstract Nares Strait is one of the primary Arctic export pathways for sea ice and freshwater, connecting the Arctic Ocean to the subpolar North Atlantic. The southward transport along the strait, primarily driven by the higher sea level in the Arctic compared to Baffin Bay, has occasionally been observed to reverse.

Improved polar geostrophic surface currents from satellite altimetry
Surface ocean currents in polar regions can be monitored by satellite altimetry-derived geostrophic currents. However, they are characterized by an irregular and sparse data sampling. Therefore, novel methods like an unsupervised classification for detecting water areas within the sea ice area and a combination strategy based on a principal component ...

Two Lateral Stirring Regimes in the Northeast Pacific
Abstract Lateral stirring is a key process shaping the physical and biogeochemical state of the ocean, yet it remains under‐sampled and poorly understood, particularly at submesoscales (1–80 km). Along Line P, a long‐term transect in the Northeast Pacific, lateral stirring was characterized using 15 glider lines with an effective horizontal resolution ...

Abstract A strong westward zonal wavenumber‐2 quasi‐4‐day wave (Q4DW) during the 2018/2019 Northern Hemisphere sudden stratospheric warming (SSW) is both captured by Aura Microwave Limb Sounder (MLS) observations and our new whole neutral atmosphere data assimilation system.

ABSTRACT Quantifying where marine organisms are born and subsequently disperse to is essential for fisheries management. Here, we conducted Lagrangian particle tracking of viviparous rockfish (Sebastes spp.) collected in the Southern California Bight over the course of 16 years.

Abstract Kinetic energy (KE) transfer between spatial scales contributes to the ocean's energy budget by linking scales of KE supply and KE dissipation. Numerical simulations have indicated that for scales smaller than the baroclinic deformation radius, cross‐scale KE transfer has complex spatial and temporal variability, modulated by mixed layer ...
