Interdecadal changes in intensity of the oxygen minimum zone off Concepción, Chile (~ 36° S), over the last century

Creator:: Srain, B., Pantoja, S., Sepúlveda, J., Lange, C. B., Muñoz, P., Summons, R. E., McKay, J., and Salamanca, M.
Abstract:: We reconstructed oxygenation changes in the upwelling ecosystem off Concepción (36° S), Chile, using inorganic and organic proxies in a sediment core covering the last ca. 110 years of sedimentation in this area. Authigenic enrichments of Mo, U and Cd were observed between ca. 1935 and 1971 CE, implying a...

GRACE storage-streamflow hystereses reveal the dynamics of regional watersheds

Creator:: Sproles, E. A., Leibowitz, S. G., Reager, J. T., Wigington, P. J. Jr., Famiglietti, J. S., and Patil, S. D.
Abstract:: We characterize how regional watersheds function as simple, dynamic systems through a series of hysteresis loops. These loops illustrate the temporal relationship between runoff and terrestrial water storage using measurements from NASA's Gravity Recovery and Climate Experiment (GRACE) satellites in three regional-scale watersheds (>150 000 km² ) of the Columbia...

Bed conduction impact on fiber optic distributed temperature sensing water temperature measurements

Creator:: O'Donnell Meininger, T. and Selker, J. S.
Abstract:: Error in distributed temperature sensing (DTS) water temperature measurements may be introduced by contact of the fiber optic cable sensor with bed materials (e.g., seafloor, lakebed, streambed). Heat conduction from the bed materials can affect cable temperature and the resulting DTS measurements. In the Middle Fork John Day River, apparent...

Complex network theory, streamflow, and hydrometric monitoring system design

Creator:: Halverson, M. J. and Fleming, S. W.
Abstract:: Network theory is applied to an array of streamflow gauges located in the Coast Mountains of British Columbia (BC) and Yukon, Canada. The goal of the analysis is to assess whether insights from this branch of mathematical graph theory can be meaningfully applied to hydrometric data, and, more specifically, whether...

Effects of Cu/Zn Superoxide Dismutase (sod1) Genotype and Genetic Background on Growth, Reproduction and Defense in Biomphalaria glabrata

Creator:: Bonner, Kaitlin M., Bayne, Christopher J., Larson, Maureen K., and Blouin, Michael S.
Abstract:: Resistance of the snail Biomphalaria glabrata to the trematode Schistosoma mansoni is correlated with allelic variation at copper-zinc superoxide dismutase (sod1). We tested whether there is a fitness cost associated with carrying the most resistant allele in three outbred laboratory populations of snails. These three populations were derived from the...

A bioenergetics model to evaluate demographic consequences of disturbance in marine mammals applied to gray whales

Creator:: Villegas-Amtmann, S., Schwarz, L. K., Sumich, J. L., and Costa, D. P.
Abstract:: While sophisticated tools are used to monitor behavioral changes of large marine vertebrates, determining whether these changes are meaningful for management and conservation is challenging. The Population Consequences of Disturbance model proposed a bioenergetics model to detect biologically meaningful population responses, where disturbance costs are linked to lost energy. The...
