Dilute solution molecular characterization and drag reducation studies of high molecular weight polyethylene oxide

Creator:: Jones, Brian Dion
Abstract:: The molecular weight distributions of two high molecular weight (M[subscript w]>>1 million) polyethylene polymers, WSR-308 and WSR-301, were characterized with gel permeation chromatography (GPC) coupled with a multi-angle laser light scattering detector (MALLS). The M[subscript w] of the WSR-308 was found to be 5.10x10⁶ g/mol with a molecular weight range...

Active acoustic examination of the diving behavior of murres foraging on patchy prey

Creator:: Benoit-Bird, Kelly J., Kuletz, Kathy, Heppell, Scott, Jones, Nathan, and Hoover, Brian
Abstract:: During the 2008 and 2009 breeding seasons of murres Uria spp., we combined visual observations of these predators with active acoustics (sonar), fish trawls, zooplankton net tows, and hydrographic measurements in the area surrounding breeding colonies in the southeastern Bering Sea. We acoustically detected thousands of bubble trails that were...

A cross-shelf gradient in δ¹⁵N stable isotope values of krill and pollock indicates seabird foraging patterns in the Bering Sea

Creator:: Jones, Nathan M., Hoover, Brian A., Heppell, Scott A., and Kuletz, Kathy J.
Abstract:: Concurrent measurements of predator and prey δ¹⁵N isotope values demonstrated that a cross-shelf isotopic gradient can propagate through a marine food web from forage species to top-tier predators and indicate foraging areas at a scale of tens of kilometers. We measured δ¹³C and δ¹⁵N in muscle tissues of thick-billed murres...

Prey Patch Patterns Predict Habitat Use by Top Marine Predators with Diverse Foraging Strategies

Creator:: Benoit-Bird, Kelly J., Battaile, Brian C., Heppell, Scott A., Hoover, Brian, Irons, David, Jones, Nathan, Kuletz, Kathy J., Nordstrom, Chad A., Paredes, Rosana, Suryan, Robert M., Waluk, Chad M., and Trites, Andrew W.
Abstract:: Spatial coherence between predators and prey has rarely been observed in pelagic marine ecosystems. We used measures of the environment, prey abundance, prey quality, and prey distribution to explain the observed distributions of three co-occurring predator species breeding on islands in the southeastern Bering Sea: black-legged kittiwakes (Rissa tridactyla), thick-billed...

Clovis Age Western Stemmed Projectile Points and Human Coprolites at the Paisley Caves

Creator:: Jenkins, Dennis L., Davis, Loren G., Stafford, Thomas W., Jr., Campos, Paula F., Hockett, Bryan, Jones, George T., Cummings, Linda Scott, Yost, Chad, Connolly, Thomas J., Yohe, Robert M., II, Gibbons, Summer C., Raghavan, Maanasa, Rasmussen, Morten, Paijmans, Johanna L. A., Hofreiter, Michael, Kemp, Brian M., Barta, Jodi Lynn, Monroe, Cara, Gilbert, M. Thomas P., and Willerslev, Eske
Abstract:: The Paisley Caves in Oregon record the oldest directly dated human remains (DNA) in the Western Hemisphere. More than 100 high-precision radiocarbon dates show that deposits containing artifacts and coprolites ranging in age from 12,450 to 2295 ¹⁴C years ago are well stratified. Western Stemmed projectile points were recovered in...

C., Winstrup, Mai, Wong, Gifford J., and Woodruff, Thomas E.
Abstract:: The last glacial period exhibited abrupt Dansgaard–Oeschger climatic oscillations, evidence of which is preserved in a variety of Northern Hemisphere palaeoclimate archives¹. Ice cores show that Antarctica cooled during the warm phases of the Greenland Dansgaard–Oeschger cycle and vice versa[superscript 2,3], suggesting an interhemispheric redistribution of heat through a mechanism...
