Preliminary investigations on picoplankton-related precipitation of alkaline-earth metal carbonates in meso-oligotrophic lake Geneva (Switzerland)

Journal of Limnology, 2013
In the course of a routine water-quality survey in meso-oligotrophic lake Geneva (Switzerland), suspended matter was collected by filtration on 0.2 μm membranes in July and August 2012 at the depth of maximal chlorophyll a (Chl a) concentration (2 mg m–3)

Microbialites on the northern shelf of Lake Van, eastern Türkiye#: Morphology, texture, stable isotope geochemistry and age

Sedimentology, Volume 71, Issue 3, Page 850-870, April 2024.
ABSTRACT Lake Van, the world's largest alkaline lake, hosts some of the largest microbialite towers worldwide, which are considered as modern analogues of ancient stromatolites. This study investigates the links between microbialite evolution, geology, climate and hydrology, and the role of biotic and abiotic processes in microbialite growth and ...

Evolution and dynamics of the vertical temperature profile in an oligotrophic lake [PDF]

, 2020
In this study, the fine-scale responses of a stratified oligotrophic karstic lake (Kozjak Lake, Plitvice Lakes, Croatia; the lake fetch is 2.3 km, and the maximum depth is 46 m) to atmospheric forcing on the lake surface are investigated.

Alkaline saline lakes: A chemical evolution experiment evaluating the stability of formaldehyde in an aqueous saline environment

Heliyon
Formaldehyde condensation in the presence of a mineral catalyst and under alkaline conditions is considered to be a ''messy'' chemical system due to its dependence on the complex chemical equilibrium between the reaction intermediates, which has a ...
