Data resources were derived from a passive seismic survey of the northern St. Helens Shear Zone on geothermal leases 12-24 km north of Mount St. Helens for phase 2 of the Geothermal Play-Fairway Analysis of Washington State Prospects. A 20 seismic station array of broadband seismometers was deployed with irregular spacing (1-4 km) over an area of 12 km to image seismogenic features and their damage zones in the shallow crust.

California State University Long Beach evaluated hydraulic connectivity among geothermal wells using Periodic Hydraulic Testing (PHT) and Distributed Acoustic Sensing (DAS). The principal was to create a pressure signal in one well and observe the responding pressure signals in one or more observation wells to assess the permeability and storage of the fracture network that connects the two wells. DAS measured strain at mHz frequency in monitoring wells in response to PHT. DAS file sampled at 1kHz
with a standard fiber optic cable during the 240 second period step test at well FSE13.
These data were collected in the laboratory located at California State University Long Beach. They consist of DAS data collected from a fiber optic cable placed in a tank of water, subjected to oscillating head. These tests are described in the article linked below.

This dataset contains maps of deformation covering Raft River, Idaho from 2007 to 2010 calculated from interferometric synthetic aperture radar data. This dataset is used in the study entitled "Inferring geothermal reservoir processes at the Raft River Geothermal Field, Idaho, USA through modeling InSAR-measured surface deformation" by F. Liu, et al. This dataset was derived from raw SAR data from the Envisat satellite missions operated by the European Space Agency (ESA) that are copyrighted by ESA and were provided through the WInSAR consortium at the UNAVCO facility. All pair directories use the image acquired on 3/11/2007 as a reference image.

The data set shows performance of economical calcium phosphate cement (Fondu) blended with fly ash, class F (FAF) in carbon steel corrosion protection tests (corrosion rate, corrosion current and potential), bond- and matrix strength, as well as matrix strength recovery after imposed damage at 300C. The corrosion protection and lap-shear bond strength data are given for different Fondu/FAF ratios, the matrix strength data recoveries are reported for 60/40 weight % Fondu/FAF ratios. Effect of sodium phosphate on bond strength, corrosion protection and self-healing is demonstrated.

Fugro Gravity and Magnetics Services (Houston) with Fugro Electro Magnetics Italy Srl carried out a full tensor, broadband magnetotelluric survey of 59 soundings under contract from University of Alaska. Two MT field teams deployed up to 3 MT systems each (ADU-07e Metronix receivers and sensors) for overnight recording, thus producing up to 6 MT soundings per day. Fieldwork was completed between August 13 and August 28, 2012. Inversion for 3D resistivity structure was performed using the Fugro RLM-3D MT code. Full tensor complex impedances were inverted in the frequency range from 0.032 Hz to 5.62 kHz, using 4 frequencies per decade, on a 384 core cluster. Both unconstrained (blind) and constrained inversions were carried out. For the constrained inversion, the starting and a priori model in 3D inversions included shallow structure from resistivity-depth maps obtained from the Resolve airborne EM survey, conducted by Fugro Airborne Surveys Corp., Mississauga, Canada.
