TL;DR: A global survey covering 196 dry inland waters shows that their CO2 emissions share fundamental drivers and constitute a substantial fraction of the carbon cycled by inland waters, increasing current inland water carbon flux estimates by 6%.
Journal ArticleDOI
First Experiences in Mapping Lake Water Quality Parameters with Sentinel-2 MSI Imagery
TL;DR: Preliminary results allow us to assume that Sentinel-2 will be a valuable tool for lake monitoring and research, especially taking into account that the data will be available routinely for many years, the imagery will be frequent, and free of charge.
Journal ArticleDOI

TL;DR: In this paper, a pan-European typology and classification system was developed for shallow lakes, which can easily be extended to all lakes, and two iterations were tested in the field on tranches of 66 lakes.
Journal ArticleDOI
Lake‐size dependency of wind shear and convection as controls on gas exchange

TL;DR: In this paper, high-frequency physical observations from 40 temperate lakes were used to examine the relative contributions of wind shear (u*) and convection (w*) to turbulence in the surface mixed layer.
Journal ArticleDOI

TL;DR: In this article, the authors collected data from a global network of automated lake observatories to test hypotheses regarding the drivers of ecosystem metabolism, and estimated daily rates of respiration and gross primary production (GPP) for up to a full year in each lake, via maximum likelihood fits of a free-water metabolism model to continuous highfrequency measurements of dissolved oxygen concentrations.
