Wall (2022), entitled "The 3.1 Ma to 100 ka Goat Rocks Volcanic Complex: Persistence and Evolution of Magmatism at a Long-Lived Major Andesite Locus on the Cascade Arc." Each appendix is a file (e.g. Word...

Volcanic Eruptions in the Deep Sea

Creator:: Rubin, Kenneth H., Soule, S. Adam, Chadwick, William W., Jr., Fornari, Daniel J., Clague, David A., Embley, Robert W., Baker, Edward T., Perfit, Michael R., Caress, David W., and Dziak, Robert P.
Abstract:: Volcanic eruptions are important events in Earth’s cycle of magma generation and crustal construction. Over durations of hours to years, eruptions produce new deposits of lava and/or fragmentary ejecta, transfer heat and magmatic volatiles from Earth’s interior to the overlying air or seawater, and significantly modify the landscape and perturb...

Late Cenozoic Foreland-to-Hinterland Low-Temperature Exhumation History of the Kashmir Himalaya

Creator:: Gavillot, Yann, Meigs, Andrew J., Sousa, Francis J., Stockli, Daniel, Yule, Doug, and Malik, Manzoor
Abstract:: New apatite and zircon (U-Th)/He cooling ages quantify late Cenozoic exhumation patterns associated with fault activity across the Kashmir Himalaya. Apatite (U-Th)/He (AHe) cooling ages of detrital grains from the Sub-Himalayan foreland sediments indicate significant resetting. AHe data and thermal modeling reveal cooling and exhumation initiated by 4Ma at the...

Variations in Gas and Water Pulses at an Arctic Seep: Fluid Sources and Methane Transport

Creator:: Hong, Wei-Li, Torres, Marta E., Portnov, A., Waage, M., Haley, B., and Lepland, A.
Abstract:: Methane fluxes into the oceans are largely dependent on the methane phase as it migrates upward through the sediments. Here we document decoupled methane transport by gaseous and aqueous phases in Storfjordrenna (offshore Svalbard) and propose a three-stage evolution model for active seepage in the region where gas hydrates are...

Regionally consistent Western North America paleomagnetic directions from 15 to 35 ka: Assessing chronology and uncertainty with paleosecular variation (PSV) stratigraphy

Creator:: Reilly, Brendan T., Stoner, Joseph S., Hatfield, Robert G., Abbott, Mark B., Marchetti, David W., Larsen, Darren J., Finkenbinder, Matthew S., Hillman, Aubrey L., Kuehn, Stephen C., and Heil, Clifford W., Jr.
Abstract:: New Paleomagnetic Secular Variation (PSV) data from Fish Lake, Utah, USA, along with previously published regional records, allow us to build an independently dated Western North America PSV stack (WNAM17) from about 35 to 15 ka that quantifies dating and paleomagnetic uncertainties. In February 2014, we recovered a composite 11-m-long...

Early to Late Holocene Surface Exposure Ages From Two Marine-Terminating Outlet Glaciers in Northwest Greenland

Creator:: Reusche, Melissa M., Marcott, Shaun A., Ceperley, Elizabeth G., Barth, Aaron M., Brook, Edward J., Mix, Alan C., and Caffee, Marc W.
Abstract:: Terrestrial chronologies from southern Greenland provide a detailed deglacial history of the Greenland Ice Sheet (GIS). The northern GIS margin history, however, is less established. Here we present surface exposure ages from moraines associated with two large outlet glaciers, Petermann and Humboldt, in the northwestern sector of the GIS. These...

Hydroacoustic monitoring of oceanic spreading centers: Past, present, and future

Creator:: Dziak, Robert P., Bohnenstiehl, Delwayne R., and Smith, Deborah K.
Abstract:: Mid-ocean ridge volcanism and extensional faulting are the fundamental processes that lead to the creation and rifting of oceanic crust, yet these events go largely undetected in the deep ocean. Currently, the only means available to observe seafloor-spreading events in real time is via the remote detection of the seismicity...

Impact of Convective Activity on Precipitation delta O-18 in Isotope-Enabled General Circulation Models

Creator:: Hu, Jun, Emile-Geay, Julien, Nusbaumer, Jesse, and Noone, David
Abstract:: The delta O-18 signal preserved in paleoarchives is widely used to reconstruct past climate conditions. In many speleothems, this signal is classically interpreted via the amount effect. However, recent work has shown that precipitation delta O-18 (delta O-18(p)) is greatly influenced by convective processes distinct from precipitation amount, and new...

Recycled Components in Mantle Plumes Deduced From Variations in Halogens (Cl, Br, and I), Trace Elements, and He-3/He-4 Along the Hawaiian-Emperor Seamount Chain

Creator:: Broadley, Michael W., Sumino, Hirochika, Graham, David W., Burgess, Ray, and Ballentine, Chris J.
Abstract:: Halogens are primarily located within surface reservoirs of the Earth; as such they have proven to be effective tracers for the identification of subducted volatiles within the mantle. Subducting lithologies exhibit a wide variety of halogen compositions, yet the mantle maintains a fairly uniform signature, suggesting halogens may be homogenized...

Evaluation of Compartmentalized Aquifers in the Walla Walla Subbasin of Oregon Using Isotopic and Geochemical Tracers

Creator:: van Stolk, Courtney A.
Abstract:: The Walla Walla Subbasin (WWSB) in Oregon is underlain by formations of the extensive Columbia River Basalt Group (CRBG) which have been deformed by post-Miocene folding and faulting. Extensive irrigation with groundwater from these basalt groups, as well as sedimentary aquifers and surface water diversions from the Walla Walla River,...
