Kate Allstadt, ESS Graduate Student
Repeating earthquakes near the Summit of Mount Rainier: Volcanic or Glacial? (and how we're going to find out)
Correlation of earthquake swarm activity with weather. A) Temperatures at Paradise and Camp Muir, B) cumulative precipitation at Paradise, C) Streamgage heights for the White River downstream from Northern glaciers and the Puyallup river downstream of western glaciers. D) Upper-air barometric pressure in hPa interpolated to 4200 meters from nearest NCER/NCAR Reanalysis gridpoint E) Number of repeating earthquakes detected per hour. 1) Start of multiplet activity, 2) First Phase begins 3) Storm invigorates phase 1, 4) Multiplet activity temporarily ceases, 5) Second phase of activity begins with 2 June storm 6) End of multiplet activity.

Testing for 3,000 km of tectonic translation of northern Washington by Pbisotopes in detrital sediments from the Methow Basin
Lead isotopic concentration data collected from detrital sediment from the Methow Basin. Data was collected using a series of Pb leaching techniques followed by a Multicollector-Inductively Coupled Plasma Mass Spectrometer (MC-ICPMS). Other isotopic concentrations were collected and plotted, and will be compared to the batholith data from the Peninsular Ranges Batholith to determine the sediments’ potential source location.

Discussion of two ocean types in 3D inversion of magnetotelluric data: constant depth & varying conductivity v. varying depth & constant conductivity
The most important feature is the variable resistivity ocean, visible as the bright colors along the edge of South America (the main blue part of the image). My talk will discuss some of the pros and cons of this style of ocean creation versus a more topographically accurate ocean with constant resistivity.

Drumbeats and Screams on Redoubt Volcano
Each box is a velocity spectrogram from the same seismic station for six nearly consecutive volcanic explosions, where t=0 is the time of the explosion. The bright, upward "gliding" lines are harmonic tremor, where the frequency of this tremor increases from a few Hz to nearly 30 Hz in the minutes before each explosion. The repeatability and high frequency content of this tremor is very unique, and has compelled us to present an alternative to the commonly accepted explanations for harmonic tremor on other volcanoes.

U, Th, Pb and Sr Isotopic Composition of Northwest Rift Zone Basalts on Tenerife, Canary Islands.
Sr isotope ratio vs Th/U disequilibrium. 238U decays to 230Th indirectly, and so the two isotopes will stay at radioactive equilibrium if left undisturbed (that is, n1λ1 = n2λ2, or (230Th/238U) = 1). Disequilibrium results from fractionation events such as partial melting, but equilibrium is reestablished in about 5 half lives (~380,000 yr). The data suggest a correlation between Sr isotope signature and level of disequilibrium.

Determining the thickness and extent of Antarctic ice during glacial/interglacial cycles
Cosmogenic radionuclide concentrations are a function of exposure to cosmic rays and radioactive decay. Burial of a sample under ice or sediment shields the sample from the incoming cosmic-ray flux. The ratio of 26Al to 10Be vs 10Be is plotted and contour lines indicate exposure and burial time. The half-lives of 26Al and 10Be are 708 kyr and 1.36 Myr, respectively. The results of 5 cycles of exposure (20 kyr) and burial (100 kyr) with no erosion are depicted by the upper plot and the red line on the lower plot.
