New publications from two former NOSAMS guest students

Jessie Pearl started as a MIT/WHOI joint program student under Jeff Donnelly and Kevin Anchukaitis.  Jessie worked with NOSAMS to do help develop reconnaissance radiocarbon dating- a method to get quick radiocarbon results at a lower cost and at a reduced precision- for organic carbon samples.  She finished her PhD at the University of Arizona and her work on the Atlantic white cedar, A late Holocene subfossil Atlantic white cedar tree-ring chronology from the northeastern United States, is now published.  Jessie is now a post doc with the USGS at their Seattle Office.

Beverly Barnett, a graduate student at the University of Florida, came to NOSAMS as a graduate student intern.  She analyzed radiocarbon in chronological layers of fish otoliths and eye lenses to develop natural, permanent biogeochemical markers of petrocarbon in the northern Gulf of Mexico food web following the Deepwater Horizon oil spill.  Her most recent work was published earlier this year: Life history of northern Gulf of Mexico Warsaw grouper Hyporthodus nigritus inferred from otolith radiocarbon analysis.
