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

Journal 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.

Long-Term Variability on Suspended Particulate Matter Loads From the Tributaries of the World’s Largest Choked Lagoon

Frontiers in Marine Science, 2022
Continental freshwater contributions are the main long-term control on the variability of suspended particulate matter (SPM) concentrations in choked lagoons.

Spreading and mixing of large river plumes in the World Ocean

Frontiers in Marine Science
River plumes are important parts of the land–ocean matter fluxes and provide the key stage of transformation of river discharge and river-borne matter in the sea. However, both the plume-sea mixing budget and the ultimate fate of continental discharge in

NW Iberia Shelf Dynamics. Study of the Douro River Plume.

Frontiers in Marine Science, 2014
River plumes are one of the most important mechanisms that transport the terrestrial materials to the coast and the ocean. Some examples of those materials are pollutants, essential nutrients, which enhance the phytoplankton productivity or sediments ...

The Amazon River plume—a Lagrangian view

Limnology and Oceanography: Methods
AbstractHydrographic data, nutrient data and bulk rates of nitrate uptake and primary production were determined in the Amazon River plume (ARP) in the Western Tropical North Atlantic (WTNA) during three cruises in May 2018, June/July 2019, with RV Endeavor and April/May 2021 with RV Meteor.

Modelling the variability and dynamics of river plumes in Hawke’s Bay, Aotearoa New Zealand

Frontiers in Marine Science
A quarter of the freshwater entering the global ocean originates from small rivers, yet the dynamics and environmental impacts of plumes generated by small rivers are understudied.

The Influence of River Discharge on Nutrient Export and Phytoplankton Biomass Off the Central Chile Coast (33°–37°S): Seasonal Cycle and Interannual Variability

Frontiers in Marine Science, 2018
Using in situ hydro-chemical data and MODIS-SeaWiFS ocean color images as a proxy of river plumes and phytoplankton biomass from 2000 to 2014, this study documents the temporal co-variability of river discharge, plume area, nitrate and phosphate export ...

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

Frontiers 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 ...

BIN1 and ALDH1B1 Deficiency in Colonic Smooth Muscle Drives Mitochondrial Dysfunction and Fibrosis in Slow‐Transit Constipation

Advanced Science, EarlyView.
Slow‐transit constipation (STC) is a disabling motility disorder with unclear smooth‐muscle mechanisms. Spatial proteomic analysis of STC patient colon reveals both the central pathogenic role of smooth muscle cells (SMCs) in STC and novel regulators of intestinal motility, BIN1 and ALDH1B1.

Analysis of the most important river plumes on the Atlantic and Mediterranean Iberian coast by means of satellite imagery

Frontiers in Marine Science, 2014
Rivers discharges cause the formation of buoyant plumes in the adjacent coastal area at their mouths, which are characterized by low-salinity water and controlled by outflow inertia, rotation (Coriolis) effects, buoyancy, wind, and tide forcing.
