Low‐Frequency Ocean Waves Triggered by Tropical Cyclones via Seafloor Distributed Acoustic Sensing

Journal of Geophysical Research: Oceans, Volume 131, Issue 3, March 2026.
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 ...

Improved polar geostrophic surface currents from satellite altimetry

, 2021
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 ...

Development of a variational SEASAT data analysis technique [PDF]

Oceans are data-sparse areas in terms of conventional weather observations. The surface pressure field obtained solely by analyzing the conventional weather data is not expected to possess high accuracy. On the other hand, in entering asynoptic data such

Interaction of Ocean Currents and Seamounts: Near‐Bottom Dynamics Around Atlantis II

Journal of Geophysical Research: Oceans, Volume 131, Issue 3, March 2026.
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

Journal of Geophysical Research: Oceans, Volume 131, Issue 3, March 2026.
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.

Seasonal Variation of Submesoscale Ageostrophic Motion and Geostrophic Energy Cascade in the Kuroshio

Journal of Marine Science and Engineering
The study of submesoscale ageostrophic motion is crucial for enhancing our comprehension of ocean dynamics. This paper employs global sea surface velocity reanalysis data and mixed layer depth data to examine the factors influencing submesoscale ...

Episodic Northward Transport Along Nares Strait Brings Anomalously Warm Water Into the Arctic Ocean

Journal of Geophysical Research: Oceans, Volume 131, Issue 3, March 2026.
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.

Two Lateral Stirring Regimes in the Northeast Pacific

Journal of Geophysical Research: Oceans, Volume 131, Issue 3, March 2026.
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 ...

Quasi‐4‐Day Waves During the 2018/2019 SSW and Their Coupling to the Ionosphere Based on Whole Atmosphere Data Assimilation

Space Weather, Volume 24, Issue 3, March 2026.
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.
