Seismotectonics of the Explorer region

Creator:: Braunmiller, Jochen and Nábělek, John
Abstract:: The Explorer region offshore western Canada is a tectonically complex area surrounded by the Pacific, North America, and Juan de Fuca plates. Existing tectonic models for the region differ fundamentally. Proposed plate configurations range from multiple independent plate fragments to an Explorer plate now fused to North America along the...

Pervasive mantle plume head heterogeneity: Evidence from the late Cretaceous Caribbean-Colombian oceanic plateau

Creator:: Kerr, Andrew C, Tarney, John, Kempton, Pamela D., Spadea, Piera, Nivia, Alvaro, Marriner, Giselle F., and Duncan, Robert A.
Abstract:: In SW Colombia picritic pillow lavas and tuffs, as well as breccias composed of picritic clasts, occur interspersed with basalts of the Central Cordillera and represent accreted portions of the similar to 90 Ma Colombian/Caribbean oceanic plateau (CCOP). We present new geochemical data for these picrites and high-MgO basalts from...

Terrigenous organic matter in sediments from the Fly River delta-clinoform system (Papua New Guinea)

Creator:: Goni, Miguel A., Monacci, Natalie, Gisewhite, Rachel, Crockett, John, Nittrouer, Charles, Ogston, Andrea, Alin, Simone R., and Aalto, Rolf
Abstract:: Although an inordinate fraction of the global sediment flux to the ocean occurs in tropical mountainous river margins, little is known regarding the sources and fate of organic matter in these systems. To address these knowledge gaps, the distribution and composition of organic matter in sediments from the Fly River...

Northern Monterey Bay upwelling shadow front : observations of a coastally and surface-trapped bouyant plume

Creator:: Woodson, C. B., Washburn, L., Barth, John A., Hoover, D. J., Kirinicich, A. R., McManus, M. A., Ryan, J. P., and Tyburczy, J.
Abstract:: During the upwelling season in central California, northwesterly winds along the coast produce a strong upwelling jet that originates at Point Año Nuevo and flows southward across the mouth of Monterey Bay. A convergent front with a mean temperature change of 3.77 ± 0.29°C develops between the warm interior waters...

Transpression between two warm mafic plates: The Queen Charlotte Fault revisited

Creator:: Rohr, Kristin M. M., Scheidhauer, Maren, and Tréhu, Anne Martine
Abstract:: The Queen Charlotte Fault is a transpressive transform plate boundary between the Pacific and North American plates offshore western Canada. Previous models for the accommodation of transpression include internal deformation of both plates adjacent to the plate boundary or oblique subduction of the oceanic plate; the latter has been the...

Spatial distributions of oxygenated organic compounds (dicarboxylic acids, fatty acids, and levoglucosan) in marine aerosols over the western Pacific and off the coast of East Asia: Continental outflow of organic aerosols during the ACE-Asia campaign

Creator:: Mochida, Michihiro, Kawamura, Kimitaka, Umemoto, Nobuhiko, Kobayashi, Minoru, Matsunaga, Sou, Lim, Ho-Jin, Turpin, Barbara J., Bates, Timothy S., and Simoneit, Bernd R. T.
Abstract:: Aerosol sampling for major oxygenated organic compounds (dicarboxylic acids, fatty acids, and levoglucosan) was conducted from 15 March to 19 April 2001 on board the National Oceanic and Atmospheric Administration R/V Ronald H. Brown over the western North Pacific, the East China Sea, and the Sea of Japan, as part...

Aerosol particles collected on aircraft flights over the northwestern Pacific region during the ACE-Asia campaign: Composition and major sources of the organic compounds

Creator:: Simoneit, Bernd R. T., Kobayashi, Minoru, Mochida, Michihiro, Kawamura, Kimitaka, and Huebert, Barry J.
Abstract:: Atmospheric particulate matter, collected over the polluted east Asia/Pacific region in spring 2001 during research flights with the National Center for Atmospheric Research (NCAR) C-130 aircraft, was analyzed for different types of organic compounds using capillary gas chromatography–mass spectrometry. More than 70 organic species were detected in the aerosols and...

Records of geomagnetic reversals from volcanic islands of French Polynesia 1. Paleomagnetic study of a polarity transition in a lava sequence from the island of Huahine

Creator:: Roperch, Pierrick and Duncan, Robert A.
Abstract:: We report the behavior of the earth's magnetic field for a transition recorded in lavas at the volcanic island of Huahine in French Polynesia, south-central Pacific Ocean. Detailed intermediate fields are observed that record an apparent N-N excursion. The available K-Ar ages indicate that most volcanic rocks of the southern...

Magmatism in the Bransfield Basin: Rifting of the South Shetland Arc?

Creator:: Fretzdorff, Susanne, Worthington, Tim J., Haase, Karsten M., Hekinian, Roger, Franz, Leander, Keller, Randall A., and Stoffers, Peter
Abstract:: Bransfield Basin is an actively extending marginal basin separating the inactive South Shetland arc from the northern Antarctic Peninsula. Rift-related volcanism is widespread throughout the central Bransfield Basin, but the wider eastern Bransfield Basin was previously unsampled. Lavas recovered from the eastern subbasin form three distinct groups: (1) Bransfield Group...

Erosion by rivers and transport pathways in the ocean: A provenance tool using 40Ar--39Ar incremental heating on fine-grained sediment

Creator:: VanLaningham, Sam, Duncan, Robert A., and Pisias, Nicklas G.
Abstract:: We use Ar-40-Ar-39 incremental heating to fingerprint bulk fluvial sediment entering the northeast Pacific Ocean, with the long-term intent of tracking sediment source and transport changes from the terrestrial system to the marine environment through time. We show reproducible age spectra from individual rivers accounting for the majority of sediment...
