POLENET

POLENET Project

The Polar Earth Observing Network (POLENET) is a large international, multidisciplinary project which is a core activity of the International Polar Year (IPY) 2007-2009.  The project combines Seismic and GPS instrumentation at remote sites in Antarctica.  The data collected during the POLENET experiment will enable new studies of the inner earth, tectonic plates, climate, and weather.  U.S. POLENET projects are supported by the National Science Foundation. EPIC supports the U.S. seismic portion of POLENET by providing specialized cold-hardened, equipment, field support, and training for University based field teams.

Frequently Asked Questions Regarding Data Requests from PH5 Data Sets

Here are frequently asked questions regarding data requests from PH5 data sets archived at the EarthScope DMC.  The answers are based upon the perspective the user is at the Data Request Form, which is available for each PH5 data set via its "Request" link found on the PH5 data set web page of the EarthScope DMC website.

EPIC supports Salton Seismic Imaging Project (SSIP)

Six EPIC staff members were in Southern California this March to support the Salton Seismic Imaging Project (SSIP).  The project is funded by NSF through both the MARGINS Program (now GeoPRISMS) and the EarthScope Program, and funded by the U. S. Geological Survey through the Multi-Hazards Demonstration Project. The project includes researchers from Virginia Tech, Caltech, the USGS, and Mexican partner institutions CICESE and UABC, Mexicali.

Requirements for EPIC Passive Experiments (SEED)

  Data and format for archiving

In order to accept your passive-source data for archiving please comply with the procedures and standards below. EPIC staff are available to assist you with meeting the requirements of archiving your SEED data as stated in the EPIC Data Delivery Policy

Regarding the archiving of SEED data, the policy may be summarized in three points:

EarthScope Orientation Week Kick-starts a Busy Summer for Student Interns

For the last few years, several students have gathered at the EPIC (PIC) for the EarthScope Undergraduate Internship Orientation Week.  In the EarthScope Undergraduate Intern program, fifteen students fan out to conduct seismological research at thirteen
host institutions.  The program is organized and run by Michael Hubenthal of EarthScope.  This year, the staff for the week-long orientation program included Rick Aster (NMT), Greg Chavez (PIC), Kent Condie (NMT), Katie Foster (U. of Wyoming & Program Alumnus), Bruce Harrison (NMT), Michael Hubenthal (EarthScope), Hunter Knox (Sandia National Lab), Jesse Lawrence (Stanford University), William McIntosh  (NM Bureau of Geology), Sandra Saldaña (Noble Energy), John Taber (EarthScope), and Dave Thomas (PIC), along with Student Assistant Rob Anthony (NMT Grad Student & Program Alumnus).

Pegasus Datalogger

The Pegasus is a 3 channel high-resolution data logger. It is very low power and easily configurable via a handheld device. The Pegasus is lightweight and small in form factor. The Pegasus has 32 gigabytes of internal recording space, and is downloaded via free software through USB. It supplies MiniSEED data along with StationXML to smoothly allow data archival. It also has built-in sensor controls, automatic mass re-centering, and calibration functions. The Pegasus is currently supplied as a set with a Trillium Compact sensor for a small station footprint and ease of installation.

Power Box

The Power Box is a combination of enclosure, solar charge controller, and connectors which ensure the battery is charged and the instrumentation is powered. Below are some pictures of the EPIC power box (and below that is the old standard EPIC power box) . All the power boxes have a 12-15 amp load capacity and a Low Voltage Disconnect (LVD) to prevent damage to the battery. These boxes are designed to work with any nominal 12 volt solar panel and any deep cycle gel-cell lead acid battery.

Visitors from Ecuador

Three engineers from the Escuela Politecnica Nacional Ecuador, Instituto Geofísico, spent the first two weeks of May here at EPIC. They are planning a network of 63 permanent broadband stations, 25 emergency sites, and 70 accelerometer stations in Ecuador. These stations will be used to monitor volcanic activity and seismic events. Ecuador is home to more than 20 volcanoes, so this is an important undertaking not only for the scientific knowledge it will provide, but also for the safety of the Ecuadoran people.

EPIC Announces Software release: Nexus, a simple tool for creating SEED meta-data.

EPIC is pleased to announce the release of Nexus, a simple tool for creating SEED meta-data.

Nexus is a software tool with a graphical interface that allows users to quickly and easily create and modify SEED meta-data. It outputs StationXML, the recently adopted replacement format for Dataless SEED. Nexus greatly simplifies preparing data for archival at the DMC.
