Eutrophication leads to the formation of a sulfide-rich deep-water layer in Lake Sevan, Armenia.

Khoren Avetisyan, Natella Mirzoyan, Rayford B Payne, Vardan Hayrapetyan, Alexey Kamyshny,

Lake Sevan is a meso-eutrophic water body, which was severely impacted by anthropogenic level decrease, pollution and eutrophication during the last century. Starting in the 1970s, these processes resulted in the formation of an oxygen-depleted hypolimnion during summer-autumn stratification of the lake. In this work, we demonstrate for the first ...

Can stable isotopes quantify soil carbon build-up from organic fertilizers?

Floriane Jamoteau, Jérôme Balesdent, Isabelle Basile-Doeslch, Emmanuel Tillard, Antoine Versini,

The application of organic fertilizers (OF) can supply carbon (C) to the soil in crop fields. OF-derived C (OF-C) is often estimated using the differential method that can be biased due to indirect effects of OF on soil C. This study tested three methods to quantify OF-C: (i) the widespread ... Read more >>
