Near‐Inertial Wave Trapping Inside a Fine‐Scale Anticyclonic Eddy During the BioSWOT‐Med 2023 Cruise: Turbulence and Energy Flux

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

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 ...

A python tool for AUV-borne ADCP current data processing

Instrumentation viewpoint, 2015
Most Autonomous Underwater Vehicles (AUVs) mount Doppler sensors to navigate precisely underwater, where the Global Positioning System (GPS) is unavailable. These sensors -aside of providing accurate AUV velocity with respect to the ground-, can perform currents profiling, measuring currents along the water column.

Direct Observations of Strong Jets Transporting Deep and Bottom Water Into the Indian Ocean Through the Fracture Zones of the Southwest Indian Ridge

Journal of Geophysical Research: Oceans, Volume 131, Issue 3, March 2026.
Abstract The Indian Ocean plays a crucial role in the abyssal overturning circulation, transforming Antarctic Bottom Water (AABW) into lighter water. In the western Indian Ocean, the only path for AABW to reach the subtropics as part of the global overturning is through the fracture zones of the Southwest Indian Ridge.

Estimation of heading gyrocompass error using a GPS 3DF system: Impact on ADCP measurements

Scientia Marina, 2002
Traditionally the horizontal orientation in a ship (heading) has been obtained from a gyrocompass. This instrument is still used on research vessels but has an estimated error of about 2-3 degrees, inducing a systematic error in the cross-track velocity ...

ICES Data Guidelines for Shipboard ADCP data. (Compiled May 1999; revised April 2006).

, 2006
ADCPs (acoustic doppler current profiler) were first introduced to the oceanography community in the late 1970s (Rowe and Young, 1979). The instrument measures water veloc ity over a range of depths using doppler shifts in active acoustic signals. ADCPs may be moored on a traditional oceanographic mooring (see moored ADCP guidelines) or attached to

Tracing Coupled GCM Equatorial Pacific Climatological Biases via Surface Flux Adjustments

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 3, March 2026.
Abstract Global weather and climate forecasts hinge on the ability of coupled general circulation models (CGCMs) to simulate ocean‐atmosphere interactions in the tropical Pacific. Yet most CGCMs develop tropical Pacific biases, such as an overly‐intense equatorial cold tongue (ECT), which limit their simulation skill.

SWOT Geostrophic Velocity Validation Against In Situ Measurements in the California Current

Earth and Space Science
The Surface Water and Ocean Topography (SWOT) mission provides high‐resolution sea surface height (SSH) observations from the Ka‐band Radar Interferometer (KaRIn), with the potential to improve our understanding of ocean circulation dynamics.

A Semi‐Analytical Model for Predicting the Depth‐Averaged Maximum Longitudinal Velocity in Fully Ice‐Covered Confluences

Water Resources Research, Volume 62, Issue 3, March 2026.
Abstract At river confluences, the complex hydrodynamics result in significant alterations to flow structures, and the maximum velocity zone serves as one of the primary drivers of pollutant transport and riverbed erosion. This study investigates maximum longitudinal velocity formation in fully ice‐covered confluences, statistically validating the ...
