Atmospheric CO₂ over the last 1000 years: A high-resolution record from the West Antarctic Ice Sheet (WAIS) Divide ice core

Creator:: Ahn, Jinho, Brook, Edward J., Mitchell, Logan, Rosen, Julia, McConnell, Joseph R., Taylor, Kendrick, Etheridge, David, and Rubino, Mauro
Abstract:: We report a decadally resolved record of atmospheric CO₂ concentration for the last 1000 years, obtained from the West Antarctic Ice Sheet (WAIS) Divide shallow ice core. The most prominent feature of the pre-industrial period is a rapid ∼7 ppm decrease of CO₂ in a span of ∼20–50 years at...

Temporal and spatial variation of atmospherically deposited organic contaminants at high elevation in Yosemite National Park, California, USA

Creator:: Bradford, David F., Stanley, Kerri A., Tallent, Nita G., Sparling, Donald W., Nash, Maliha S., Knapp, Roland A., McConnell, Laura L., and Simonich, Staci L. Massey
Abstract:: Contaminants used at low elevation, such as pesticides on crops, can be transported tens of kilometers and deposited in adjacent mountains in many parts of the world. Atmospherically deposited organic contaminants in the Sierra Nevada Mountains of California, USA, have exceeded some thresholds of concern, but the spatial and temporal...

The WAIS Divide deep ice core WD2014 chronology - Part 2: Annual-layer counting (0-31 ka BP)

Creator:: Sigl, Michael, Fudge, Tyler J., Winstrup, Mai, Cole-Dai, Jihong, Ferris, David, McConnell, Joseph R., Taylor, Ken C., Welten, Kees C., Woodruff, Thomas E., Adolphi, Florian, Bisiaux, Marion, Brook, Edward J., Buizert, Christo, Caffee, Marc W., Dunbar, Nelia W., Edwards, Ross, Geng, Lei, Iverson, Nels, Koffman, Bess, Layman, Lawrence, Maselli, Olivia J., McGwire, Kenneth, Muscheler, Raimund, Nishiizumi, Kunihiko, Pasteris, Daniel R., Rhodes, Rachael H., and Sowers, Todd A
Abstract:: We present the WD2014 chronology for the upper part (0–2850 m; 31.2 ka BP) of the West Antarctic Ice Sheet (WAIS) Divide (WD) ice core. The chronology is based on counting of annual layers observed in the chemical, dust and electrical conductivity records. These layers are caused by seasonal changes...

Onset of deglacial warming in West Antarctica driven by local orbital forcing

Creator:: Fudge, T. J., Steig, Eric J., Markle, Bradley R., Schoenemann, Spruce W., Ding, Qinghua, Taylor, Kendrick C., McConnell, Joseph R., Brook, Edward J., Sowers, Todd, White, James W. C., Alley, Richard B., Cheng, Hai, Clow, Gary D., Cole-Dai, Jihong, Conway, Howard, Cuffey, Kurt M., Edwards, Jon S., Edwards, R.

Abstract:: The cause of warming in the Southern Hemisphere during the most recent deglaciation remains a matter of debate[superscript 1,2]. Hypotheses for a Northern Hemisphere trigger, through oceanic redistributions of heat, are based in part on the abrupt onset of warming seen in East Antarctic ice cores and dated to 18,000...

Fine-scale parallel patterns in diversity of small benthic Arctic charr (Salvelinus alpinus) in relation to the ecology of lava/groundwater habitats

Creator:: Kristjansson, Bjarni K., Skulason, Skuli, Snorrason, Sigurour S., and Noakes, David L. G.
Abstract:: It is critical to study factors that are important for origin and maintenance of biological diversity. A comparative approach involving a large number of populations is particularly useful.We use this approach to study the relationship between ecological factors and phenotypic diversity in Icelandic Arctic charr (Salvelinus alpinus). Numerous populations of...

Father-Child Transmission of School Adjustment: A Prospective Intergenerational Study

Creator:: Pears, Katherine C., Kim, Hyoun K., Capaldi, Deborah, Kerr, David C. R., and Fisher, Philip A.
Abstract:: The intergenerational transmission of school adjustment was explored in a sample of 213 children and their fathers. The fathers were participants in a longitudinal study that began when they were in the fourth grade, and their children have been assessed at the ages of 21 months and 3, 5, and...

Extended-release Naltrexone for Alcohol and Opioid Dependence : A Meta-Analysis of Healthcare Utilization Studies

Creator:: Hartung, Daniel, McCarty, Dennis, Fu, Rongwei, Wiest, Katharina, Chalk, Mady, and Gastfriend, David R.
Abstract:: Through improved adherence, once-monthly injectable extended-release naltrexone (XR-NTX) may provide an advantage over other oral agents approved for alcohol and opioid dependence treatment. The objective of this study was to evaluate cost and utilization outcomes between XR-NTX and other pharmacotherapies for treatment of alcohol and opioid dependence. Published studies were...

Linking marine predator diving behavior to local prey fields in contrasting habitats in a subarctic glacial fjord

Creator:: Womble, Jamie N., Blundell, Gail M., Gende, Scott M., Horning, Markus, Sigler, Michael F., and Csepp, David J.
Abstract:: Foraging theory predicts that animals will adjust their foraging behavior in order to maximize net energy intake and that trade-offs may exist that can influence their behavior. Although substantial advances have been made with respect to the foraging ecology of large marine predators, there is still a limited understanding of...

Cold Seep Epifaunal Communities on the Hikurangi Margin, New Zealand: Composition, Succession, and Vulnerability to Human Activities

Creator:: Bowden, David A., Rowden, Ashley A., Thurber, Andrew R., Baco, Amy R., Levin, Lisa A., and Smith, Craig R.
Abstract:: Cold seep communities with distinctive chemoautotrophic fauna occur where hydrocarbon-rich fluids escape from the seabed. We describe community composition, population densities, spatial extent, and within-region variability of epifaunal communities at methane-rich cold seep sites on the Hikurangi Margin, New Zealand. Using data from towed camera transects, we match observations to...

Does location really matter? An inter-colony comparison of seabirds breeding at varying distances from productive oceanographic features in the Bering Sea

Creator:: Harding, Ann, Paredes, Rosana, Suryan, Robert, Roby, Daniel, Irons, David, Orben, Rachael, Renner, Heather, Young, Rebecca, Barger, Christopher, Dorresteijn, Ine, and Kitaysky, Alexander
Abstract:: Central place foragers, such as breeding seabirds, need to commute between their nests and foraging grounds, thus close proximity of the breeding colony to productive oceanographic features might be beneficial for seabird reproduction. We tested this hypothesis by investigating the at-sea foraging and breeding behavior of thick-billed murres (Uria lomvia)...
