Effects of storm size and frequency on nitrogen retention, denitrification, and N2O production in bioretention swale mesocosms

RA Norton, JA Harrison, C Kent Keller, KB Moffett - Biogeochemistry, 2017 - Springer
Reported nitrogen (N) retention efficiencies for bioretention swales vary widely, but reasons
for this are not well-understood, in part because almost no studies have measured (or …

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

Movements of the thermocline lead to high variability in benthic mixing in the nearshore of a large lake

MR Chowdhury, MG Wells… - Water Resources …, 2016 - Wiley Online Library
Abstract The thermocline of Lake Ontario is in constant motion, and as it washes back and
forth along the sloping lakebed there is a striking asymmetry in near‐bed stratification and …

[HTML][HTML] Understanding How Reservoir Operations Influence Methane Emissions: A Conceptual Model

HI Jager, RM Pilla, CH Hansen, PG Matson, B Iftikhar… - Water, 2023 - mdpi.com

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
