Seafloor Sediments, Morphologic Features, and Geotechnical Properties of Harrison Bay in the Alaskan Beaufort Sea

Earth and Space Science, Volume 13, Issue 5, May 2026.
Abstract Sediments on Arctic continental shelves are impacted by sea ice and ice‐related processes for up to 9 months per year. As a result, seabed morphology in cold regions can exhibit features such as ice scours which are absent on lower‐latitude shelves.

Topographic generation of submesoscale centrifugal instability and energy dissipation

Nature Communications, 2016
Most of the ocean kinetic energy is contained in the large scale geostrophic currents and the pathways of energy toward dissipation are still in question.

Estimating ocean currents from the joint reconstruction of absolute dynamic topography and sea surface temperature through deep learning algorithms [PDF]

Ocean Science
Our study focuses on absolute dynamic topography (ADT) and sea surface temperature (SST) mapping from satellite observations, with the primary objective of improving the satellite-derived ADT (and derived geostrophic currents) spatial resolution ...

Rotating gravity currents: small-scale and large-scale laboratory experiments and a geostrophic model [PDF]

, 2007
Laboratory experiments simulating gravity-driven coastal surface currents produced by estuarine fresh-water discharges into the ocean are discussed. The currents are generated inside a rotating tank filled with salt water by the continuous release of ...

Climatic Higher‐Order Balanced Winds Beyond Geostrophic and Gradient Wind Fields

Earth and Space Science, Volume 13, Issue 5, May 2026.
Abstract We present a novel approach to derive three‐dimensional Climatic Higher‐Order Balanced (CHOB) wind fields from thermodynamic state variables in the free troposphere and stratosphere. The CHOB method is developed for monthly synoptic‐scale wind field estimation, utilizing commonly used balanced winds (geostrophic and gradient wind) enhanced by ...

The flow of the Antarctic circumpolar current over the North Scotia Ridge [PDF]

, 2009
The transports associated with the Subantarctic Front (SAF) and the Polar Front (PF) account for the majority of the volume transport of the Antarctic Circumpolar Current (ACC).

A Machine Learning Parameterization for the Internal Gravity Wave Spectrum

Journal of Geophysical Research: Oceans, Volume 131, Issue 5, May 2026.
Abstract We introduce a stochastic model designed to parametrize the spectral properties of internal waves, using two functions that represent the semidiurnal spectral tidal cusps and the energy continuum between the inertial and the buoyancy frequencies.

The Propagation of Internal Waves in a Geostrophic Current

Journal of Physical Oceanography, 1981
Abstract The paper presents the WKB theory of internal wave propagation in a large-scale geostrophic mean flow with vertical as well as horizontal shear. As an application a mean flow with isopycnals having constant slope but arbitrary spacing is considered and the behavior of waves at turning points and critical layers is discussed.
