Headwaters to oceans: Ecological and biogeochemical contrasts across the aquatic continuum

MA Xenopoulos, JA Downing… - Limnology and …, 2017 - Wiley Online Library
While the disciplines of oceanography and limnology often operate in isolate, freshwater,
estuarine, and marine ecosystems are intricately linked. The emphasis of this special issue …

Active pathways of anaerobic methane oxidation across contrasting riverbeds

L Shen, L Ouyang, Y Zhu, M Trimmer - The ISME journal, 2019 - academic.oup.com
Anaerobic oxidation of methane (AOM) reduces methane emissions from marine
ecosystems but we know little about AOM in rivers, whose role in the global carbon cycle is …

Hydrologic controls on pCO2 and CO2 efflux in US streams and rivers

S Liu, PA Raymond - Limnology and Oceanography Letters, 2018 - Wiley Online Library
Streams and rivers emit petagrams of CO2, yet there is little known about how discharge
variability impacts stream CO2 at broad scales. This article analyzed changes of pCO2 and …

Contrasting biophysical controls on carbon dioxide and methane outgassing from streams

L Rovelli, LA Olde, CM Heppell, A Binley… - Journal of …, 2022 - Wiley Online Library
Small headwater streams are recognized for intense outgassing to the atmosphere of
climate‐relevant carbon dioxide (CO2) and methane (CH4). Though these headwaters are …

[HTML][HTML] Intense summer floods may induce prolonged increases in benthic respiration rates of more than one year leading to low river dissolved oxygen

MG Hutchins, G Harding, HP Jarvie, TJ Marsh… - Journal of Hydrology …, 2020 - Elsevier
The supply of readily-degradable organic matter to river systems can cause stress to
dissolved oxygen (DO) in slow-flowing waterbodies. To explore this threat, a multi …

Towards a sampling design for characterizing habitat-specific benthic biodiversity related to oxygen flux dynamics using Aquatic Eddy Covariance

IF Rodil, KM Attard, J Norkko, RN Glud, A Norkko - PLoS One, 2019 - journals.plos.org
The Aquatic Eddy Covariance (AEC) technique has emerged as an important method to
quantify in situ seafloor metabolism over large areas of heterogeneous benthic communities …

Dynamics of dissolved organic matter in headwaters: comparison of headwater streams with contrasting DOM and nutrient composition

O Fovet, DM Cooper, DL Jones, TG Jones, CD Evans - Aquatic Sciences, 2020 - Springer
Dissolved organic matter (DOM) in freshwaters is recognised as a significant and active
component of the global carbon budget. DOM exported from terrestrial ecosystems may be …

Benthic primary production and respiration of shallow rocky habitats: a case study from South Bay (Doumer Island, Western Antarctic Peninsula)

L Rovelli, KM Attard, CA Cárdenas, RN Glud - Polar Biology, 2019 - Springer
Rocky benthic communities are common in Antarctic coastal habitats; yet little is known
about their carbon turnover rates. Here, we performed a broad survey of shallow (< 65 m …

Aquatic biogeochemical eddy covariance fluxes in the presence of waves

MH Long - Journal of Geophysical Research: Oceans, 2021 - Wiley Online Library
The eddy covariance (EC) technique is a powerful tool for measuring atmospheric exchange
rates that was recently adapted by biogeochemists to measure aquatic oxygen fluxes. A …

Sediment–water surface area along rivers: water column versus benthic

JR Gardner, MW Doyle - Ecosystems, 2018 - Springer
Aquatic ecosystems have two distinct zones: the water column and benthic zone. Although
the benthic zone has received considerable attention, recent studies have found the water …
