Latest Quaternary dinoflagellate cyst climatostratigraphy for three cores from the Falkland Trough, Scotia and Weddell seas, Southern Ocean
Dinoflagellate cyst analysis has been undertaken on three Kasten cores taken from the Falkland Trough, Scotia Sea and Weddell Sea in the area of the Antarctic Peninsula. Two of these cores are situated to the north of the maximum sea-ice limit and one, from the Weddell Sea, is sited within the maxim...

Dinoflagellate cyst analysis has been undertaken on three Kasten cores taken from the Falkland Trough, Scotia Sea and Weddell Sea in the area of the Antarctic Peninsula.

The recovered dinoflagellate cyst assemblages underscore the importance of the maximum sea-ice limit as a basic biogeographic boundary for dinoflagellate cyst distributions. Our results also demonstrate that in general the palaeoceanography of the Holocene and Late Pleistocene has remained reasonably constant and reflects present conditions to a large extent.
