Sediment trapping by dams creates methane emission hot spots.
Andreas Maeck,Tonya DelSontro,Daniel Frank Mcginnis,Helmut W Fischer,Sabine Flury,Mark Schmidt,Peer Fietzek,Andreas Lorke +7 more
TL;DR: It is shown that sediment accumulation correlates with methane production and subsequent ebullitive release rates and may therefore be an excellent proxy for estimating methane emissions from small reservoirs and suggest that sedimentation-driven methane emission from dammed river hot spot sites can potentially increase global freshwater emissions by up to 7%.
Journal ArticleDOI
Extreme variations of pCO2 and pH in a macrophyte meadow of the Baltic Sea in summer: evidence of the effect of photosynthesis and local upwelling.
TL;DR: The results demonstrate the high variability of the carbonate system in nearshore macrophyte meadows depending on meteorology and biological activities and highlight the need to incorporate these variations in future pCO2 scenarios and experimental designs for nearshore habitats.
Journal ArticleDOI
Optical tools for ocean monitoring and research
C. F. Moore,Andrew H. Barnard,Peer Fietzek,Marlon R. Lewis,Heidi M. Sosik,Sheri N. White,Oliver Zielinski +6 more
TL;DR: In this article, a wide range of optical measurements of ocean color and suspended and dissolved materials within the water column are used to infer information related to an increasing set of related biogeochemical and physical parameters.
Journal ArticleDOI
In situ Quality Assessment of a Novel Underwater pCO2 Sensor Based on Membrane Equilibration and NDIR Spectrometry
TL;DR: In this paper, the authors present a detailed quality assessment of a novel underwater sensor for the measurement of CO2 partial pressure (pCO2) based on surface water field deployments carried out between 2008 and 2011.
Journal ArticleDOI
In Situ CO2 and O2 Measurements on a Profiling Float
TL;DR: In this article, the utility of profiling floats as a platform for combined gas measurements of CO2 partial pressure (pCO2) and O2 has been highlighted for marine biogeochemical research, where a small-sized and submersible pCO2 sensor and an optode O2 sensor were used for high resolution measurements in the surface ocean layer.
