A 15,800-year record of atmospheric lead deposition on the Devon Island Ice Cap, Nunavut, Canada: Natural and anthropogenic enrichments, isotopic composition, and predominant sourcesDownload2007Abstract: Using appropriate clean methods for handling and preparation, 57 ice samples from the Devon Island Ice Cap, representing the period 134 to 15,800 years before present (BP), were analyzed for Pb, Sc, and Pb isotopes (Pb-206, Pb-207, Pb-208) using ICP-SMS. The greatest Pb concentrations...
A model - data intercomparison of CO2 exchange across North America: Results from the North American Carbon Program site synthesisDownload2010McCaughey, H., Sahoo, A. K., Riley, W., Lokupitiya, E., Price, D. T., Riciutto, D. M., Ciais, P., Dietze, M., Sprintsin, M., Liu, S. G., Chen, J. M., Barr, A., Law, B. E., Schwalm, C. R., Tian, H. Q., Oechel, W. C., Williams, C. A., Davis, K. J., Verma, S. B., Luo, Y. Q., Verbeeck, H., Tonitto, C., Dragoni, D., Peng, C. H., Margolis, H., Gu, L. H., Li, Z. P., Ma, S. Y., Matamala, R., Grant, R., Desai, A., Anderson, R., Hollinger, D., Flanagan, L. B., Fischer, M. L., Poulter, B., Li, L. H., Baker, I., Sun, J. E., Monson, R. K., Schaefer, K., Chen, G. S., Lafleur, P., Kucharik, C., Black, T.A., Izaurralde, R. C., Arain, M. A.Abstract: Our current understanding of terrestrial carbon processes is represented in various models used to integrate and scale measurements of CO2 exchange from remote sensing and other spatiotemporal data. Yet assessments are rarely conducted to determine how well models simulate carbon...
1993Long dry spells (sequences of dry days) are rare events, but they are important because they correlate significantly with the area burned during bad wildfire years. Previous attempts to model the frequency of dry spells have been successful for spells of short duration, but have failed for...
A model-data comparison of gross primary productivity: Results from the North American Carbon Program site synthesisDownload2012Anderson, R., Poulter, B., Matamala, R., Lokipitiya, E., Chen, J.M., Verbeeck, H., Davis, K.J., Weng, E., Curtis, P.S., Tonitto, C., Munger, J.W., Ricciuto, D., Chen, J., Gu, L., Humphreys, E., Desai, A.R., Price, D.T., Raczka, B.M., Zhou, X., Peng, C., Torn, M., Hollinger, D.Y., Riley, W.J., Roulet, N., Black, A., Bolstad, P., Baker, I., Thornton, P., Monson, R., Jain, A., Law, B., Gough, C., Margolis, H.A., Dimitrov, D., Grant, R.F., Liu, S., McCaughey, J.H., Hilton, T.W., Sahoo, A., Dietze, M., Schaefer, K., Williams, C., Dragoni, D., Tian, H., Vargas, R., Schwalm, C.R., Richardson, A.D., Oechel, W., Kucharik, C., Barr, A., Altaf Arain, M.Accurately simulating gross primary productivity (GPP) in terrestrial ecosystem models is critical because errors in simulated GPP propagate through the model to introduce additional errors in simulated biomass and other fluxes. We evaluated simulated, daily average GPP from 26 models against...
A study of the relation of meteorological variables to monthly provincial area burned by wildfire in Canada 1953-80Download1988The relation between meteorological variables and the monthly area burned by wildfire from May to August 1953-80 in nine Canadian \"provinces\" was investigated. A purely statistical approach to estimating the monthly provincial area burned, using meteorological variables as predictors, succeeded...
2004Abstract: An improved corer and associated equipment for obtaining continuous samples of frozen peat are described. We developed the system through laboratory and field trials-on Bathurst Island, Nunavut, Canada in 2000 and Nordvesto, Carey Islands, Greenland, in 2001-as part of efforts to...
2008Most richness estimators currently in use are derived from models that consider sampling with replacement or from the assumption of infinite populations. Neither of the assumptions is suitable for sampling sessile organisms such as plants where quadrats are often sampled without replacement and...
2000Land management practices are known to influence runoff through alteration of the antecedent soil water For accurate estimation of runoff, direct measurement of antecedent soil water would be necessary. This study investigated antecedent soil water and the potential for summer storm runoff under...
Antimony in recent, ombrotrophic peat from Switzerland and Scotland: Comparison with natural background values (5,320 to 8,020 (14)C yr BP) and implications for the global atmospheric Sb cycleDownload2004Abstract:  The lowest concentrations, atmospheric fluxes, and enrichments of Sb in a Swiss bog were found in peat samples dating from 8,020 to 5,320 (14)C yr BP when Sb inputs were proportional to those of Sc and effectively controlled by deposition of soil dust. For comparison with these...
