WAIS Divide Biological Data from J. Priscu and C. Foreman, Montana State University
Entry ID: Paleo_Records_of_Biotic_and_Abiotic_Particles_in_Polar_Ice_Cores


Summary
Abstract: Data from J. Priscu and C. Foreman, Montana State University. WAIS Divide core (WDC05Q, Stick D). Ice core samples were decontaminated following (Christner et al., 2005 Icarus, 174: 572-584) and handled in a class 100 environmental chamber. Meltwater was pre-filtered (30um) and gently sonicated prior to staining biotic particles with 5uM SYTO 60 (Invitrogen) for 5 min. Counts of biotic and abiotic particles were obtained using a Microcyte flow cytometer. Bacterial Productivity was determined via the incorporation of tritiated thymidine (TdR) into DNA at 6C following method of Fuhrman and Azam 1982 Marine Biology, 66: 109-120. The dissolved organic carbon (DOC) concentration of the ice core samples was obtained using a Shimadzu TOC 5000, see Christner et al., 2006 Limnology and Oceanography, 51(6): 2485-2501 for explanation of methods.
