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.

SWOT Geostrophic Velocity Validation Against In Situ Measurements in the California Current
Earth and Space ScienceThe 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.

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 5, May 2026.Abstract Hurricane Harvey (2017) produced 31 net‐erosional washout channels on San Jose Island, Texas, USA, where offshore‐directed flows cut through two dune ridges and the beach. Channel growth was affected by natural, pre‐existing aeolian topography, rather than prior washover channels or infrastructure. We investigate how offshore directed outwash,

The parameterisation of turbulence in the marine environment [PDF]
, 2016 There are many problems in the fields of flow modelling around structures and tidal stream energy yield analysis which require a thorough understanding of the turbulent and time-averaged flow speeds in marine environments.

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.

Hydraulic Effects of Channel Realignment and Floodplain Reconnection in a Headwater Stream
Water Resources Research, Volume 62, Issue 5, May 2026.Abstract Channel realignment and floodplain reconnection are increasingly used as nature‐based solutions for flood management, yet their hydraulic effects remain poorly quantified in field settings of moderate‐gradient, small order channels. This study examines the impact of such interventions on hydraulic response in a headwater catchment, Goldrill ...

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

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 ...
