This data set is comprised of radiocarbon ages derived from organic
carbon that is bound in diatom frustules found in sediment cores from
the Southern Ocean. The sediments were analyzed using a accelerator
mass spectrometer (AMS) at the National Ocean Sciences Accelerator
Mass Spectrometry Facility, Woods Hole Oceanographic Institution.
Research was made possible by ... a grant from the US National Science
Foundation Office of Polar Programs and collaboration with French
researchers who provided approximately 65% of the samples analyzed.
Currently, the data is available in spreadsheet format but only from
the investigators listed below. Results available to date indicate
that diatoms are often transported and that diatom-bound organic
carbon can accordingly be substantially older than the sediment
horizon in which it is found. The data set will be published as soon
as results from diatomaceous debris sorted according to degree of
preservation is available.
