The results imply that most of the isoGDGTs preserved in the Oligocene deposits on the Newfoundland sediment drifts are derived from Thaumarchaeota. Furthermore, a moderate to high amount of brGDGTs were observed, suggesting a continental source of lipids in the marine sediment of the two studied sites (U1406 and U1411).
