Here we examine the characteristics of sediment that make them suitable or unsuitable for geomagnetic paleointensity dating.Not far above the Earth’s surface the effect of other sources becomes as strong as or stronger than that of the geomagnetic dynamo.In the discussion that follows, each of these sources is considered and the respective causes explained.This record contains a complete Holocene sequence beginning with the transition from grounded ice to a floating ice shelf and ending with the modern recession of the Larsen-A ice shelf.This approach provides chronological control to a sediment sequence that lack appropriate material for radiocarbon dating.Please enter the requested iinformation below to get your Certificate of Completion as a Virtual Geochronologist.
