Floodplain emergent wetlands as rearing habitat for fishes and the implications for wetland enhancement

Creator:: Henning, Julie A.
Abstract:: Seasonal emergent wetlands in the Pacific Northwest have not been regarded traditionally as fish rearing habitat, despite access to such habitat when river flows overtop riverbanks and connect to the floodplain. As a result, restoration and enhancement projects to remediate for the loss of such wetland habitat are being implemented...

Basalts erupted along the Tongan fore arc during subduction initiation: Evidence from geochronology of dredged rocks from the Tonga fore arc and trench

Creator:: Meffre, Sebastian, Falloon, Trevor J., Crawford, Tony J., Hoernle, Kaj, Hauff, Folkmar, Duncan, Robert A., Bloomer, Sherman H., and Wright, Dawn J.
Abstract:: A wide variety of different rock types were dredged from the Tonga fore arc and trench between 8000 and 3000 m water depths by the 1996 Boomerang voyage. ⁴⁰Ar-³⁹Ar whole rock and U-Pb zircon dating suggest that these fore arc rocks were erupted episodically from the Cretaceous to the Pliocene...

Detailed volcanostratigraphy of an accreted seamount: Implications for intraplate seamount formation

Creator:: Schnur, Susan R. and Gilbert, Lisa A.
Abstract:: Seamounts are a ubiquitous feature of the seafloor but relatively little is known about their internal structure. A seamount preserved in the Franciscan mélange of California suggests a sequence of formation common to all seamounts. Field mapping, geophysical measurements, and geochemical analyses are combined to interpret three stages of seamount...

Temporal and crustal effects on differentiation of tholeiite to calcalkaline and ferro-trachytic suites, High Lava Plains, Oregon, USA

Creator:: Streck, Martin J. and Grunder, Anita L.
Abstract:: Strongly bimodal, basalt-rhyolite volcanism of the High Lava Plains Province of Oregon followed the Middle Miocene flood basalts of the Pacific Northwest and extends to recent time. During the 8 m.y. of volcanism recorded in the central High Lava Plains, in western Harney Basin, three distinct mafic magmatic trends originate...

GOES-10 microphysical retrievals in marine warm clouds: Multi-instrument validation and daytime cycle over the southeast Pacific

Creator:: Painemal, David, Minnis, Patrick, Ayers, J. Kirk, and O'Neill, Larry
Abstract:: The daytime evolution of warm cloud microphysical properties over the southeast Pacific during October–November 2008 is investigated with optical/infrared retrievals from the Tenth Geostationary Operational Environmental Satellite (GOES-10) imager. GOES-10 retrievals, produced at NASA Langley Research Center, are validated against in situ aircraft observations and with independent satellite observations. Comparisons...

Abrupt change in atmospheric CO₂ during the last ice age

Creator:: Ahn, Jinho, Brook, Edward J., Schmittner, Andreas, and Kreutz, Karl
Abstract:: During the last glacial period atmospheric carbon dioxide and temperature in Antarctica varied in a similar fashion on millennial time scales, but previous work indicates that these changes were gradual. In a detailed analysis of one event we now find that approximately half of the CO₂ increase that occurred during...

Early retreat of the Alaska Peninsula Glacier Complex and the implications for coastal migrations of First Americans

Creator:: Misarti, Nicole, Finney, Bruce P., Jordan, James W., Maschner, Herbert D. G., Addison, Jason A., Shapley, Mark D., Krumhardt, Andrea, and Beget, James E.
Abstract:: The debate over a coastal migration route for the First Americans revolves around two major points: seafaring technology, and a viable landscape and resource base. Three lake cores from Sanak Island in the western Gulf of Alaska yield the first radiocarbon ages from the continental shelf of the Northeast Pacific...

Does eddy-eddy interaction control surface phytoplankton distribution and carbon export in the North Pacific Subtropical Gyre?

Creator:: Guidi, Lionel, Calil, Paulo H. R., Duhamel, Solange, Bjoerkman, Karin M., Doney, Scott C., Jackson, George A., Li, Binglin, Church, Matthew J., Tozzi, Sasha, Kolber, Zbigniew S., Richards, Kelvin J., Fong, Allison A., Letelier, Ricardo M., Gorsky, Gabriel, Stemmann, Lars, and Karl, David M.
Abstract:: In the North Pacific Subtropical Gyre (NPSG), the regular occurrence of summer phytoplankton blooms contributes to marine ecosystem productivity and the annual carbon export. The mechanisms underlying the formation, maintenance, and decay of these blooms remain largely unknown; nitrogen fixation, episodic vertical mixing of nutrients, and meso- (<100 km) and...

Laboratory investigation of dune erosion using stereo video

Creator:: Palmsten, Margaret L. and Holman, Robert A.
Abstract:: Simple parameterizations of dune erosion are necessary for forecasting erosion potential prior to an oncoming storm. Dune erosion may be parameterized in terms of the elevation of the total water level (composed of surge, tide, and wave runup) above the dune base and period of exposure of the dune to...

Calcite dissolution in sediments of the Ontong-Java Plateau : In situ measurements of pore water O₂ and pH

Creator:: Hales, Burke and Emerson, Steve
Abstract:: We present in situ electrode measurements of sediment resistivity, pore water oxygen, and pore water pH from three stations between 2300 and 3000 m depth on the Ontong-Java Plateau in the western equatorial Pacific. One of these stations is also the site of a concurrent benthic chamber incubation experiment [Jahnke...
