ENSIS is analysing three sediment cores taken by Bioforsk from Lake Vastadtjern providing a total sediment core length of around 600 cm. The intention is to extend the record back to pre-human impact (approx 6000-7000 yrs BP). The cores were as follows;
The Gravity and Russian cores have been dated using 210Pb and the deeper Russian core has been carbon dated. ENSIS is analysing c.20 sub-samples for diatoms macrofossils and cladocera distributed throughout the whole sequence to determine the aquatic flora and fauna at various stages in the lake’s history.
The project is still ongoing
