Virioplankton Assemblage Structure in the Lower River and Ocean Continuum of the Amazon

open access: yesmSphere, 2017
The Amazon River watershed and its associated plume comprise a vast continental and oceanic area. The microbial activities along this continuum contribute substantially to global carbon and nutrient cycling, and yet there is a dearth of information on ...

A numerical study of the formation of the Rhône River plume [PDF]

open access: yesJournal of Marine Systems, 1998
A three-dimensional primitive equation ocean model is applied to the Rhone River plume (northwestern Mediterranean). The plume dynamics are analyzed through the vorticity balance of the depth-averaged current. This balance highlights the importance of the JEBAR and nonlinear terms.

River Plume Modulation by Infragravity Wave Forcing

open access: yesGeophysical Research Letters, 2022
We present measurements at the mouth of Río Maipo, a small river that discharges into an energetic surfzone on the coast of Chile, which document for the first time the plume response to infragravity (IG) wave forcing.

Lateral Border of a Small River Plume: Salinity Structure, Instabilities and Mass Transport

open access: yesRemote Sensing, 2022
The interfaces between small river plumes and ambient seawater have extremely sharp horizontal and vertical salinity gradients, often accompanied by velocity shear. It results in formation of instabilities at the lateral borders of small plumes.

Estuarine forcing of a river plume by river flow and tides [PDF]

open access: yesJournal of Geophysical Research: Oceans, 2008
Estuarine forcing of a river plume by river discharge and tides is examined with a novel data set capable of characterizing semidiurnal to annual time scales. An instrumented ferry made high‐resolution salinity measurements as it crossed the Fraser River plume, British Columbia, Canada, eight times per day over the years 2003–2006.

Monitoring the Amazon River plume from satellite observations

open access: yesGIScience & Remote Sensing
Most of our knowledge about the Amazon River plume is limited from the field experiments or modeling due to various challenges for satellite remote sensing, i.e., constant cloud coverage, atmospheric correction, and difficulties to differentiate the ...

Influence of main forcing affecting the Tagus turbid plume under high river discharges using MODIS imagery.

open access: yesPLoS ONE, 2017
The role of river discharge, wind and tide on the extension and variability of the Tagus River plume was analyzed from 2003 to 2015. This study was performed combining daily images obtained from the Moderate Resolution Imaging Spectroradiometer (MODIS ...

Non-Linear Processes in the Gironde River Plume (North-East Atlantic): Instabilities and Mixing

open access: yesFrontiers in Marine Science, 2021
Instability and mixing are ubiquitous processes in river plumes but their small spatial and temporal scales often limit their observation and analysis. We investigate flow instability and mixing processes in the Gironde river plume (Bay of Biscay, North ...

Freshwater Composition and Connectivity of the Connecticut River Plume During Ambient Flood Tides

open access: yesFrontiers in Marine Science, 2021
The Connecticut River plume interacts with the strong tidal currents of the ambient receiving waters in eastern Long Island Sound. The plume formed during ambient flood tides is studied as an example of tidal river plumes entering into energetic ambient ...

Trace Metal Fluxes of Cd, Cu, Pb and Zn From the Congo River Into the South Atlantic Ocean Are Supplemented by Atmospheric Inputs

open access: yesGeophysical Research Letters, 2023
The Congo River supplies vast quantities of trace metals (TMs) to the South Atlantic Ocean, but TM budgets for the Congo plume derived using radium isotopes for GEOTRACES cruise GA08 suggest additional input other than the river outflow.
