Journal ArticleDOI
Small-scale hydrodynamics in lakes
Alfred Wüest,Andreas Lorke +1 more
TL;DR: In this article, small-scale turbulence observations allow the mixing regimes in lakes, reservoirs, and other enclosed basins to be categorized into the turbulent surface and bottom boundary layers as well as the comparably quiet interior.
Journal ArticleDOI
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
Breathing sediments: The control of diffusive transport across the sediment-water interface by periodic boundary-layer turbulence
TL;DR: In this paper, the authors performed in situ measurements of bottom boundary-layer turbulence and of diffusive oxygen fluxes at the sediment-water interface in a medium-sized mesotrophic lake.
Journal ArticleDOI
Mixotrophs combine resource use to outcompete specialists: Implications for aquatic food webs
Jörg Tittel,Vera Bissinger,Barbara Zippel,Ursula Gaedke,Elanor M. Bell,Andreas Lorke,Norbert Kamjunke +6 more
TL;DR: It is hypothesize instead that the mixotrophic grazing strategy is responsible for deep algal accumulations in many aquatic environments, previously explained by resource availability.
Journal ArticleDOI
Earlier onset of the spring phytoplankton bloom in lakes of the temperate zone in a warmer climate
TL;DR: In this article, the authors present a model-based analysis that predicts that in a future warmer climate, the onset of the spring phytoplankton bloom will occur earlier in the year than it does at present.
