✨️RECENT NEWS: the PERMAMERC Project has published two review papers exploring mercury dynamics in Arctic permafrost ecosystems and natural organic matter characterization techniques applied to research in permafrost peatlands ✨️

[PERMAMERC @permamerc]

This review paper focused primarily on recent research employing analytical techniques (i.e. UV-Visible and Fluorescence spectroscopy; FTIR spectroscopy, NMR spectroscopy; FT-ICR-MS) to characterize natural organic matter to study biogeochemical processes in permafrost regions.

@CiimarUp @IGOT_ULisboa @istecnico @universitelaval PERMAMERC thanks the brilliant idea of ​​our Canadian colleague Raoul Couture (@universitelaval ) who brought two of his students, and the IST team for organizing these three days.

[PERMAMERC @permamerc]

The retreat for PhD students from the PERMAMERC project took place from November 20th to 22nd at @istecnico /ULisboa.

[PERMAMERC @permamerc]

Three days to discuss results and write papers in areas as diverse as microbiology (@CiimarUp ), remote sensing (@IGOT_ULisboa ) or environmental chemistry (@istecnico and @universitelaval ) of thermokarst lakes.
