Project’s description:

'Sedimentary ancient DNA - a new proxy to investigate the impact of environmental change on past and present biodiversity in Nordic Seas (NEEDED)'

The effects of ongoing climate warming are especially perceptible in the Arctic, mainly due to the rapid decline in sea ice extent over the past few decades, resulting from heat advected with Atlantic Water (a process sometimes known as “Atlantification”). The accelerated loss of sea ice in the Arctic shelf seas has a profound impact on the water column structure and therefore, on the global energy budget, the atmospheric and oceanic circulation, and the carbon cycle. In case of complete disappearance of the sea ice from the western Arctic shelf and high sea surface temperatures, the enhanced vertical stratification will reduce nutrient flux into the upper oceans, leading to reduced phytoplankton biomass and production. To predict the further development, directions and consequences of the ongoing climatic/oceanographic changes it is essential to investigate the natural Arctic environment variability and its response to external forcing in the geological timescales.

The aim of the project is to study the impact of sea surface temperatures on marine productivity in the Nordic Sea since the last deglaciation in order to recognize the spatial and temporal marine productivity variations. The doctoral research will be focusing on generating micropaleontological, palynological and biomarker records to assess Arctic sea surface temperature, sea ice cover and water mass change in the Late Quaternary. A special focus will be put on investigating the impact of climate-induced environmental changes on marine productivity and the carbon burial rates during the mid-Holocene Thermal Maximum, about 5000-9000 years ago and compare it to the current global warming.
