GREENCYCLESII

T4.2 Arnaud Heroult

This PhD project is part of an EU Marie Curie Training Network called "Greencycle II". This project will focus on improving general understanding of the influence presence and absence of permafrost has on greenhouse gas exchanges (GHG) at high latitudes with particular attention to methane. It will use established measurement sites as well as where necessary establish new sites to study specifically the seasonal dynamics and how they differ in permafrost environments compared to other northern areas. Some emphasis will be on shoulder season and winter processes since some very interesting and poorly understood emission patterns during these seasons were recently discovered in permafrost environments. The project will produce measurement based regional upscale estimates for seasonal dynamics of large scale emissions to be compared with atmospheric observations and modeling. Where appropriate the project will also work on improved process understanding of permafrost dynamics in controlled environment facilities specially designed for such experiments present in the Lund laboratories.
