Radionuclides from moored sediment trap samples
Principal investigator: Bob Anderson
Collaborators: Zanna Chase and Martin Fleisher
Institution: Lamont-Doherty Earth Observatory
Sediment trap samples were analyzed for U, Th and Pa by isotope dilution
inductively-coupled mass spectrometry. Be-10 is measured by accelerator
mass spectrometry after spiking with Be-9. Results for moorings 1-5 were
acquired by quadrapole ICP-MS (Chase, et. al.) and results for moorings
6 and 7 were acquired by magnetic sector ICP-MS (Fleisher and Anderson).
