PASSCAL Experiments http://www.passcal.nmt.edu/rss/experiments en GeoGirls http://www.passcal.nmt.edu/scheduledetails/exptnumb/201504 A series of small experiments will be designed by middle school students attending an outreach program at Mount St. Helens during the summers of 2015 and 2016. The students will design and carry out small research projects using portable seismic instruments and other geophysical techniques to record and study dynamic processes at Mount St. Helens. This experimental outreach program is part of Kate Allstadt's NSF Postdocoral fellowship starting in September, 2014 at the USGS Cascade Volcano Observatory. NW Uganda http://www.passcal.nmt.edu/scheduledetails/exptnumb/201628 A 10-station broadband network will be deployed for 18 months to investigate upper mantle structure and anisotropy as it related to plume-lithoshpere processes. Fairview aftershock http://www.passcal.nmt.edu/scheduledetails/exptnumb/201622 This is the first M5 earthquake in Oklahoma since the M5.7 Prague earthquake. This earthquake occurred along the extension of a mapped fault, which had 6 M4 earthquakes on a single fault. We would like to deploy sensors around this fault, and examine if this fault is connected with other mapped faults in this area. This would be a rapid response for the large earthquake. PIER http://www.passcal.nmt.edu/scheduledetails/exptnumb/200011 This reflects instruments in the South Pier, owned by PASSCAL. 2016 IBD http://www.passcal.nmt.edu/scheduledetails/exptnumb/201619 he IRIS Interns will deploy three BB sensors behind the PIC and leave them deployed for ~5 days. Guadeloupe Geophysics http://www.passcal.nmt.edu/scheduledetails/exptnumb/201629 Since climate is considered to be an important state-factor in transforming bedrock into a suitable substrate for life, there is a fundamental need to geophysically characterize the deep critical zone in tropical climates. Without this knowledge, it will be difficult to predict how the deep critical zone will respond to increasing global temperatures. This project will collect seed data (near surface seismic refraction) for a future grant proposal to investigate the role of climate on deep critical zone structure. Ecuador RAMP http://www.passcal.nmt.edu/scheduledetails/exptnumb/201638 RAMP deployment to record aftershocks in the wake of the April 16 2016 Pedernales earthquake in the subsection zone offshore Ecuador. Greeley http://www.passcal.nmt.edu/scheduledetails/exptnumb/201611 Northeast Colorado Induced Earthquake Study Harvard seismic refraction course http://www.passcal.nmt.edu/scheduledetails/exptnumb/201627 This is a slimple refraction experiment for the course E-PSCI 166: "Consequences of Earthquakes", that is offered from the Department of Earth and Planetary Sciences of Harvard University and the instructor Prof Dr Miaki Ishii. It involves a seismograph connected with 24 geophones of 40hz and a hummer/plate source. The experiment will take place in the yard of Harvard University. It aims to demonstrate to the students the field proceddures and the subsequent data analysis of seismic refraction experiments. WavefieldsDemo http://www.passcal.nmt.edu/scheduledetails/exptnumb/201612 The goal of this experiment is to train the IRIS community on new acquisition techniques through a demonstration of full wavefield observations, using a range of instrumentation to make observations at multiple spatial and temporal scales. The goal of these new techniques being to increase resolution and reduce aliasing - while optimizing the pool usage (using the right instruments for the right part of the spectrum). The demonstration experiment will utilize our existing pool of instrumentation as well as some newer technology to demonstrate new capabilities and modes of operation and will result in an open dataset for the community to explore.
