Do geochemical estimates of sediment focusing pass the sediment test in the equatorial Pacific?
(AMER GEOPHYSICAL UNION, 2005-01-28)
The paleoceanographic recording fidelity of pelagic sediments is limited by chemical diagenesis and physical mixing (bioturbation and horizontal sediment transport). Diagenesis and bioturbation are relatively well-studied, ...
Modeling the Suspended Sediment Transport in a Very Wide, Shallow, and Microtidal Estuary, the Río de la Plata, Argentina
(Blackwell Publishing, 2019-10)
The impact of the diverse processes responsible for the distribution of suspended sediments in the wide, shallow, and microtidal Río de la Plata estuary and the adjacent shelf is studied by means of a set of process-oriented ...
Monitoring Suspended Sediment Dynamics Using MBES
(American Society of Civil Engineers, 2010-01)
This technical note describes use of a multibeam echosounder (MBES) to quantify the dynamics of suspended sediment in a large open channel. A methodology is detailed that uses the backscatter magnitude from the MBES ...
A mixed-primal finite element approximation of a sedimentation–consolidation system
(2016)
This paper is devoted to the mathematical and numerical analysis of a strongly cou- pled flow and transport system typically encountered in continuum-based models of sedimentation–consolidation processes. The model focuses ...
Aposteriori error estimation for an augmented mixed-primal method applied to sedimentation–consolidation systems
(2018-08-15)
In this paper we develop the aposteriorierror analysis of an augmented mixed-primal finite element method for the 2D and 3D versions of a stationary flow and transport coupled system, typically encountered in sedimentati ...
Modern non-tropical mixed carbonate-siliciclastic sediments and environments of the southwestern Gulf of California, Mexico
(Sedimentary Geology, 2004)
Modern mixed carbonate-siliciclastic warm-temperate environments were studied in the southern Gulf of California (GOC), Mexico. The combined heterozoan and photozoan character is defined by the absence of true coral reef ...
Calcareous benthic foraminifera from the upper central peruvian margin: Control of the assemblage by pore water redox and sedimentary organic matter
(Inter Research, 2015)
We studied 'living' (stained) benthic foraminifera in the upper border of the Peruvian oxygen minimum zone (OMZ) to determine the relationship between species' distribution and pore water and sediment geochemistry under ...
Impact of bottom trawling on deep-sea sediment properties along the flanks of a submarine canyon
(Public Library Of Science, 2014-07)
The offshore displacement of commercial bottom trawling has raised concerns about the impact of this destructive fishing practice on the deep seafloor, which is in general characterized by lower resilience than shallow ...
HYDRODYNAMICS AND SUSPENDED SEDIMENT TRANSPORT IN THE CAMBORIU ESTUARY - BRAZIL: PRE JETTY CONDITIONS
(INST OCEANOGRAFICO, UNIV SAO PAULO, 2009)
Estuarine hydrodynamics is a key factor in the definition of the filtering capacity of an estuary and results from the interaction of the processes that control the inlet morphodynamics and those that are acting in the ...
Organic matter redox state driven by specific sources in mangrove sediments: A case study from peruvian ecosystems
(MDPI, 2021)
In order to determine the organic matter redox state in relation to specific sources in mangrove sediments, two 60 cm-long sediment cores were collected from mangrove-covered and mudflat zones within a mangrove forest in ...
