Transport and mixing observed in a pond: Description of wind‐forced transport processes and quantification of mixing rates

SM Henderson, JR Nielson, SR Mayne… - Limnology and …, 2024 - Wiley Online Library
Ponds are characterized by high biodiversity, intense biogeochemical cycling, and
susceptibility to anthropogenic impacts. Yet few studies have quantified the water velocities …

In situ flux estimates reveal large variations in methane flux across the bottom boundary layer of a eutrophic lake

SL D'Ambrosio, SM Henderson… - Limnology and …, 2022 - Wiley Online Library
Methane (CH4) produced in anoxic sediments plays a significant role in the carbon
economy of many lakes and reservoirs. CH4 released from sediments first crosses the …

Effects of riverine inflows on the climatology of a tropical Andean reservoir

A Posada‐Bedoya, A Gómez‐Giraldo… - Limnology and …, 2021 - Wiley Online Library
Field data and numerical modeling were used to investigate the effects of the riverine inflows
on the seasonality of the lake mean temperature, thermal structure, and basin‐scale internal …

Summer redox dynamics in a eutrophic reservoir and sensitivity to a summer's end drawdown event

BR Deemer, JA Harrison - Ecosystems, 2019 - Springer
In eutrophic lakes and reservoirs, reduced mixing during stratified conditions limits oxygen
(O 2) supply to the hypolimnion (that is, bottom waters). In the absence of an O 2 supply …

Periodic boundary layer separation and lateral intrusions observed above a sloping lakebed

JR Nielson, SM Henderson - Limnology and Oceanography, 2023 - Wiley Online Library
Lateral intrusions flowing from the boundaries of lakes and oceans might influence basin‐
scale distributions of heat, chemical solutes, sediments, and organisms. Here, observations …

Turbulent production in an internal wave bottom boundary layer maintained by a vertically propagating seiche

SM Henderson - Journal of Geophysical Research: Oceans, 2016 - Wiley Online Library
Internal seiches, which supply the energy responsible for mixing many lakes, are often
modeled as vertically standing waves. However, recent observations of vertical seiche …

Chemical mixing in the bottom boundary layer of a eutrophic reservoir: The effects of internal seiching on nitrogen dynamics

BR Deemer, SM Henderson… - Limnology and …, 2015 - Wiley Online Library
In lakes and reservoirs, the bottom boundary layer (BBL) mediates chemical fluxes between
sediments and the overlying water column. At the internal shoreline, where the thermocline …

Horizontal transport under wind-induced resonance in stratified waterbodies

HN Ulloa, G Constantinescu, K Chang… - Physical Review …, 2020 - APS
Periodic winds acting on a stratified waterbody can amplify normal modes of motion and
enhance the basin-scale circulation via resonance. Here, we use idealized large-eddy …

Bottom boundary layer mixing processes across internal seiche cycles: Dominance of downslope flows

JR Nielson, SM Henderson - Limnology and Oceanography, 2022 - Wiley Online Library
In a stratified lake, where an internal seiche maintained an oscillating bottom boundary layer
(BBL), processes including strain‐induced periodic stratification (SIPS), a downslope mean …
