Stable oxygen isotopes and winter bottom water temperature data from Gullmar Fjord, Skagerrak (North Sea) ...
We present 2500 years of reconstructed bottom-water temperatures (BWT) in annual to subdecadal resolution by using a fjord sediment archive from the NE Atlantic region. The BWT represent winter conditions due to the fjord hydrography and associated timing and frequency of bottom-water renewals. The...
