CT scanning

after six months of working out logistics with the OSU Vet. Med. department, CT scanning of sediment cores has proceeded (with a few bumps here or there). about 20% of the cores have been scanned.

CT data is based on differences in density (it's X-ray technology). Laminations are more easily uniquely identified with CT data than with visual inspection or with standard X-rays. I am using these data to correlate strata between cores. I am also using the CT imagery to strategically select optimal sample locations for samples used for age control (radionuclides: 14C and 210Pb).

Later this summer i hope to have some age samples collected and a paper or two submitted based on the results.
