The link between amphibole aluminum content and reaction rim mineralogy

Creator:

Ellingwood, Ross T.

Abstract:

During volcanic eruptions ascending magma undergoes decompression, resulting in a decrease of dissolved H2O. This creates unstable conditions for the hydrous mineral amphibole. As a result a reaction rim forms from anhydrous minerals such as pyroxene, plagioclase, and Fe-Ti oxides (Rutherford and Hill, 1993). There have been numerous studies done...

Geochemical data from anoxic sequences of the Nicobar Fan, recovered during International Ocean Discovery Program (IODP) Expedition 362 to the Sumatra subduction zone

Creator:

Torres, Marta E, Milliken, Kitty, Hüpers, Andre, Kim, Ji-Hoon, and Lee, S-G

Abstract:

We report on geochemical data from anoxic sequences of the Nicobar Fan, recovered during International Ocean Discovery Program (IODP) expedition 362 to the Sumatra subduction zone. Analyses include strontium and carbon isotope composition of pore fluids, elemental and isotopic composition of carbonate concretions, and whole sediment analyses.

Recruitment, Growth and Mortality of an Antarctic Hexactinellid Sponge, Anoxycalyx joubini

Creator:

Dayton, Paul K., Kim, Stacy, Jarrell, Shannon C., Oliver, John S., Hammerstrom, Kamille, Fisher, Jennifer L., O'Connor, Kevin, Barber, Julie S., Robilliard, Gordon, Barry, James, Thurber, Andrew R., and Conlan, Kathy

Abstract:

Polar ecosystems are sensitive to climate forcing, and we often lack baselines to evaluate changes. Here we report a nearly 50-year study in which a sudden shift in the population dynamics of an ecologically important, structure-forming hexactinellid sponge, Anoxycalyx joubini was observed. This is the largest Antarctic sponge, with individuals...

Fifth Oregon climate assessment

Creator:

Dalton, Meghan M., Fleishman, Erica, and Oregon Climate Change Research Institute

Abstract:

Consistent with its charge under Oregon House Bill 3543, the Oregon Climate Change Research Institute (OCCRI) conducts a biennial assessment of the state of climate change science, including biological, physical, and social science, as it relates to Oregon and the likely effects of climate change on Oregon. This fifth Oregon...

C., Vandemark, D., Vlahos, P., Wallace, D. W. R., Wanninkhof, R., and Watson, A. J.

Abstract:

The Surface Ocean CO2 Atlas (SOCAT), an activity of the international marine carbon research community, provides access to synthesis and gridded fCO2 (fugacity of carbon dioxide) products for the surface oceans. Version 2 of SOCAT is an update of the previous release (version 1) with more data (increased from 6.3...

Impact of tide-topography interactions on basal melting of Larsen C Ice Shelf, Antarctica

Creator:

Mueller, R. D., Padman, L., Dinniman, M. S., Erofeeva, S. Y., Fricker, H. A., and King, M. A.

Abstract:

Basal melting of ice shelves around Antarctica contributes to formation of Antarctic Bottom Water and can affect global sea level by altering the offshore flow of grounded ice streams and glaciers. Tides influence ice shelf basal melt rate (w(b)) by contributing to ocean mixing and mean circulation as well as...

Bimodal volcanism of the High Lava Plains and Northwestern Basin and Range of Oregon: Distribution and tectonic implications of age-progressive rhyolites

Creator:

Ford, Mark T., Grunder, Anita L., and Duncan, Robert A.

Abstract:

Multiple episodes of Oligocene and younger silicic volcanism are represented in the high lava plateau of central and southeastern Oregon. From 12 Ma to Recent, volcanism is strongly bimodal with nearly equal volumes of basalt and rhyolite. It is characterized by moderate to high silica (SiO₂ > 72 wt. %)...

Paleoseismic Record of Peninsula Segment Earthquakes on the San Andreas Fault near San Francisco, CA and possible NSAF linkage to Cascadia

Creator:

Goldfinger, Chris

Abstract:

Lake Merced results have established the lake as a viable paleoseismic site on the northern San Francisco peninsula. The lake records ~ 2300 years of event beds, 17 in total. Prior to that the lake was open to the ocean and contains marine shells consistent with an estuarine environment. The...

Reproductive phase locking of mosquito populations in response to rainfall frequency

Creator:

Shaman, Jeffrey and Day, Jonathan F.

Abstract:

The frequency of moderate to heavy rainfall events is projected to change in response to global warming. Here we show that these hydrologic changes may have a profound effect on mosquito population dynamics and rates of mosquito-borne disease transmission. We develop a simple model, which treats the mosquito reproductive cycle...

Comparison of larval development in domesticated and naturalized stocks of the Pacific oyster Crassostrea gigas exposed to high pCO₂ conditions

Creator:

Durland, Evan, Waldbusser, George, and Langdon, Chris

Abstract:

Ocean acidification (OA) has had significant negative effects on oyster populations on the west coast of North America over the past decade. Many studies have focused on the physiological challenges experienced by young oyster larvae in high pCO₂/low pH seawater with reduced aragonite saturation state (Ωarag), which is characteristic of...
