Numerical assessment of morphological and hydraulic properties of moss, lichen and peat from a permafrost peatland

5 May 2023

In January 2023 a paper related to digital retrieval of hydraulic properties of boreal mosses and lichens has been published by Simon Cazaurang, Manuel Marcoux, Oleg S. Pokrovsky, Sergey V. Loiko, Artem G. Lim, Stéphane Audry, Liudmila S. Shirokova, and Laurent Orgogozo in Hydrology and Earth System Sciences. In this work, computer assisted tomography, computational fluid dynamics simulations and pore-network modelling has been used to study 12 samples of sphagnum mosses and Cladonia lichens from the Khanymey Research Station in Western Siberia.

Field mission in Abisko – July 2022

On July 2022 a field mission to Abisko Research Station in Northern Sweden has been done. The goals were to produce a new vegetation map for Stordalen and Mielajokka catchments (see the previous HiPerBorea field mission in Abisko) based on satelite data (Auda et al., in prep) and to sample sphagnum mosses from the peatlands […]
