ENVINET Activities Catalog

ENVINET Activities Catalog

ENVINET (European network for arctic-alpine multidiciplanary environmental research) is a research infrastructure network focusing on multidisciplinary environmental research in Europe. The network involves representatives from 18 environmental research infrastructures from the European Alps to the Arctic, representatives of their users and representatives from relevant international organizations and networks. The participating infrastructures cover a broad range of environmental sciences primarily within atmospheric physics and chemistry as well as marine and terrestrial biology.

The ENVINET project directory covers data and observation activities at these stations.

Other catalogs through this service are AMAP, SAON and SEARCH, or refer to the full list of projects/activities.

1. From Soil to Ocean: Transfer of terrigenous organic carbon from permafrost soils to the Arctic Ocean

In order to estimate the effect of rising global temperatures on organic carbon (OC) stocks in the temperature-sensitivity Arctic environment, our project aims at investigating the transfer of terrestrial OC from permafrost soils to the Arctic Ocean. Detailed compositional analyses of bulk soil and sediments along a transport trajectory combined with compound-specific isotopic (13C and 14C) analysis of selected lipid biomarkers will be used to study alteration processes of organic matter occurring in the soil and its during transport. Sub-goals include to a) identify suitable biomarkers for soil organic carbon in permafrost soils, b) determine residence times of selected biomarkers in permafrost soils, fluvial and marine sediments, and c) quantify carbon transfer from source (soil) to sink (marine sediment) and its timescale.
