Medición de la concentración de sedimentos en suspensión mediante dispositivos ópticos y acústicos: aplicación en sistemas tropicales (Delta del río Mira, Colombia) Measurement of suspended sediment concentration using optical and acoustic devices: application in tropical systems (Mira River Delta, Colombia)

Latin American Journal of Aquatic Research, 2012
En los últimos años, la utilización de dispositivos ópticos (e.g. Optical Backscatter Sensor, OBS) y acústicos (e.g. Acoustic Doppler Current Profiler-ADCP) ha permitido monitorear con mayor resolución la variabilidad temporal y espacial de la ...

Characterizing Ion‐Scale Fluctuations Around Dipolarization Fronts in Earth's Magnetotail

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract In the Earth's magnetotail bursty bulk flows are often associated with dipolarizing magnetic flux bundles. The leading edges of such earthward‐moving flux bundles are called dipolarization fronts (DF). In the present study we investigate the characteristics of ion‐scale oscillations embedded inside DFs, using observations from NASA's ...

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,

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 ...

Observations of Combined Wave and Current Interactions With a High Relief Coral Reef Bottom

Journal of Geophysical Research: Oceans, Volume 131, Issue 3, March 2026.
Abstract On reefs, interaction between the flow and complex bottom topography results in drag forces on currents, dissipation of wave energy, and generation of turbulence. Here, field observations on a shallow backreef were used to investigate wave and current interactions with the bottom at scales of individual colonies across a coral reef patch. Wave

Dispersive Wave Focusing in Shoaling Water With Currents

Journal of Geophysical Research: Oceans, Volume 131, Issue 3, March 2026.
Abstract A methodology creating dispersive focusing waves on constant depth, originally proposed by Rapp and Melville (1990), https://doi.org/10.1098/rsta.1990.0098, has provided a wide range of applications studying nonlinear waves, wave breaking, and rogue waves in the open ocean.

On the Positive Bias of Peak Horizontal Velocity from an Idealized Doppler Profiler [PDF]

In the presence of 3-D turbulence, peak horizontal velocity estimates from an idealized Doppler profiler are found to be positively biased due to an incomplete specification of the vertical velocity field.

Quantifying Drag on Floating Sargassum Patches Under Combined Air and Water Forcing

Journal of Geophysical Research: Oceans, Volume 131, Issue 3, March 2026.
Abstract Laboratory experiments were conducted in a unidirectional air‐water flume with glass sidewalls to quantify drag forces acting on pelagic Sargassum spp. patches exposed to steady airflow and water current. Both live and surrogate patches, designed to replicate the morphology and buoyancy of natural sargassum, were tested over Reynolds numbers ...

Automated in situ observations of upper ocean biogeochemistry, bio-optics, and physics and their potential use for global studies [PDF]

The processes controlling the flux of carbon in the upper ocean have dynamic ranges in space and time of at least nine orders of magnitude. These processes depend on a broad suite of inter-related biogeochemical, bio-optical, and physical variables ...
