Short summary

The effects of seabird presence on permafrost peat evolution in NW Greenland were studied by tracing changes in stable C and N isotope composition along the path from bird sources into permafrost peat. The permafrost growth was triggered by organic matter and nutrient input since the neoglacial cooling and concurrent polynya establishment. The study deals with the complex response of biologic and permafrost dynamics to High Arctic climatic and oceanographic conditions of the Late Holocene.
