Distributed subglacial discharge drives significant submarine melt at a Greenland tidewater glacier

Creator:: Fried, M. J., Catania, G. A., Bartholomaus, T. C., Duncan, D., Davis, M., Stearns, L. A., Nash, J., Shroyer, E., and Sutherland, D.
Abstract:: Submarine melt can account for substantial mass loss at tidewater glacier termini. However, the processes controlling submarine melt are poorly understood due to limited observations of submarine termini. Here at a tidewater glacier in central West Greenland, we identify subglacial discharge outlets and infer submarine melt across the terminus using...

Age progressive volcanism in the New England seamounts and the opening of the Central Atlantic Ocean

Creator:: Duncan, Robert A.
Abstract:: Radiometric ages (K-Ar and ⁴⁰Ar- ³⁹Ar methods) have been determined on dredged volcanic rocks from seven of the New England Seamounts, a prominent northwest-southeast trending volcanic lineament in the northwestern Atlantic Ocean. The ⁴⁰Ar-³⁹Ar total fusion and incremental heating ages show an increase in seamount construction age from southeast to...

A captured island chain in the coast range of Oregon and Washington

Creator:: Duncan, Robert A.
Abstract:: K-Ar and ⁴⁰Ar-³⁹Ar geochronologic data reveal the Paleocene to Eocene eruptive history of volcanic centers which produced the basaltic basement rocks of the Coast Range of Oregon and Washington. Volcanism was short lived at each center and migrated with time from the northern and southern ends toward the center, near...

Evolution of the Walvis Ridge-Rio Grande rise hot spot system: implications for African and South American plate motions over plumes

Creator:: O'Connor, John M. and Duncan, Robert A.
Abstract:: Crystallization ages of volcanic rocks, dredged or drilled from the Walvis Ridge (ten sites) and the Rio Grande Rise (one site), have been determined by the ⁴⁰Ar/³⁹Ar incremental heating technique. The fundamentally age-progressive distribution of these basement ages suggests a common hot spot source for volcanism on the island of...

Deeply dredged submarine HIMU glasses from the Tuvalu Islands, Polynesia: Implications for volatile budgets of recycled oceanic crust

Creator:: Jackson, M. G., Koga, K. T., Price, A., Koppers, A. A. P., Finlayson, V. A., Konrad, K., Hauri, E. H., Kylander-Clark, A., Kelley, K. A., and Kendrick, M. A.
Abstract:: Ocean island basalts (OIB) with extremely radiogenic Pb-isotopic signatures are melts of a mantle component called HIMU (high µ, high ²³⁸U/²⁰⁴Pb). Until now, deeply dredged submarine HIMU glasses have not been available, which has inhibited complete geochemical (in particular, volatile element) characterization of the HIMU mantle. We report major, trace...

Removing Protections for Wolves and the Future of the U.S. Endangered Species Act (1973)

Creator:: Bruskotter, Jeremy T., Vucetich, John A., Enzler, Sherry, Treves, Adrian, and Nelson, Michael P.
Abstract:: In June of 2013, the U.S. Fish and Wildlife Service proposed removing gray wolves (Canis lupus, Linnaeus) from Endangered Species Act (ESA) protections throughout the conterminous United States. The proposed rule depends on a definition of endangerment that is inconsistent with the legislative history and historical implementation of the ESA,...

Geochemical evidence in the northeast Lau Basin for subduction of the Cook-Austral volcanic chain in the Tonga Trench

Creator:: Price, Allison A., Jackson, Matthew G., Blichert-Toft, Janne, Blusztajn, Jerzy, Conatser, Christopher S., Konter, Jasper G., Koppers, Anthony A. P., and Kurz, Mark D.
Abstract:: Lau Basin basalts host an array of geochemical signatures that suggest incorporation of enriched mantle source material often associated with intraplate hotspots, but the origin of these signatures remain uncertain. Geochemical signatures associated with mantle material entrained from the nearby Samoan hotspot are present in northwest Lau Basin lavas, and...

Sequencing of 15 622 gene-bearing BACs clarifies the gene-dense regions of the barley genome

Creator:: Muñoz‐Amatriaín, Maria, Lonardi, Stefano, Luo, MingCheng, Madishetty, Kavitha, Svensson, Jan T., Moscou, Matthew J., Wanamaker, Steve, Jiang, Tao, Kleinhofs, Andris, Muehlbauer, Gary J., Wise, Roger P., Stein, Nils, Ma, Yaqin, Rodriguez, Edmundo, Kudrna, Dave, Bhat, Prasanna R., Chao, Shiaoman, Condamine, Pascal, Heinen, Shane, Resnik, Josh, Wing, Rod, Witt, Heather N., Alpert, Matthew, Beccuti, Marco, Bozdag, Serdar, Cordero, Francesca, Mirebrahim, Hamid, Ounit, Rachid, Wu, Yonghui, You, Frank, Zheng, Jie, Simková, Hana, Dolezel, Jaroslav, Grimwood, Jane, Schmutz, Jeremy, Duma, Denisa, Altschmied, Lothar, Blake, Tom, Bregitzer, Phil, Cooper, Laurel, Dilbirligi, Muharrem, Falk, Anders, Feiz, Leila, Graner, Andreas, Gustafson, Perry, Hayes, Patrick M., Lemaux, Peggy, Mammadov, Jafar, and Close, Timothy J.
Abstract:: Barley (Hordeum vulgare L.) possesses a large and highly repetitive genome of 5.1 Gb that has hindered the development of a complete sequence. In 2012, the International Barley Sequencing Consortium released a resource integrating whole-genome shotgun sequences with a physical and genetic framework. However, because only 6278 bacterial artificial chromosome...

Contrasting distribution patterns of invasive and naturalized non-native species along environmental gradients in a semi-arid montane ecosystem

Creator:: Andersen, Kelly M., Naylor, Bridgett J., Endress, Bryan A., and Parks, Catherine G.
Abstract:: Questions: Mountain systems have high abiotic heterogeneity over local spatial scales, offering natural experiments for examining plant species invasions. We ask whether functional groupings explain non-native species spread into native vegetation and up elevation gradients.We examine whether non-native species distribution patterns are related to environmental variables after controlling for elevation...

Effects of Different Organic Weed Management Strategies on the Physicochemical, Sensory, and Antioxidant Properties of Machine-Harvested Blackberry Fruits

Creator:: Cavender, George, Liu, Mingyang, Hobbs, Deborah, Frei, Balz, Strik, Bernadine C., and Zhao, Yanyun
Abstract:: The effect of three different weed management strategies, non-weeding, hand weeding, and weed mat, were examined on physicochemical, sugar profile, and antioxidant properties of two cultivars of blackberry (Rubus spp), ’Marion’ and ’Black Diamond’ harvested at three time intervals during the 2012 season. Sensory analysis on flavor intensity of six...
