Long-Term Spatiotemporal Variability of Whitings in Lake Geneva from Multispectral Remote Sensing and Machine Learning

open access: yesRemote Sensing, 2022
Whiting events are massive calcite precipitation events turning hardwater lake waters to a milky turquoise color. Herein, we use a multispectral remote sensing approach to describe the spatial and temporal occurrences of whitings in Lake Geneva from 2013

Redox Zone and Trophic State as Drivers of Methane-Oxidizing Bacterial Abundance and Community Structure in Lake Sediments

open access: yesFrontiers in Environmental Science, 2022
Eutrophication is expected to increase methane production in freshwater sediments worldwide over the coming decades. Methane-oxidizing bacteria (MOB) consume a significant fraction of this sedimentary methane, but the factors that control their ...

Sedimentary biomarkers of human presence and taro cultivation reveal early horticulture in Remote Oceania

open access: yesCommunications Earth & Environment
Remote Oceania was among the last places settled by humans. However, the timing of initial human settlements and the early introduction of horticulture remain debated.

Temperature modulates stress response in mainstream anammox reactors

open access: yesCommunications Biology, 2021
Niederdorfer et al. show that different anaerobic ammonium oxidizing (anammox) bacterial species and other key biofilm taxa vary in their transcriptional responses as a function of temperature and dissolved oxygen disturbances in an engineered ecosystem.

Remote Sensing of Sun-Induced Fluorescence in a Deep Lake: Disentangling Quenching Mechanisms Improves Relationship With Chlorophyll-a Concentration Estimates

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Sun-induced fluorescence (SIF) from phytoplankton has historically been used as a proxy for chlorophyll-a (chl-a) concentration estimates in water bodies using optical earth observation data.

Machine learning reveals that sodium concentration and temperature influence alkenone occurrence in Swiss and worldwide freshwater lakes

open access: yesFrontiers in Earth Science
Lacustrine alkenones are increasingly reported in freshwater lakes worldwide, which makes them a very promising proxy to reconstruct past continental temperatures.
