Sensor Certification

Introduction:

All equipment, especially sensors and cables, are cleaned and comprehensively tested when they arrive at the PIC, regardless of whether the equipment are newly delivered from the manufacturer or being returned from an experiment.  EPIC makes every effort to ensure that all equipment are operating to the manufacturers specifications.

This article outlines the procedures undertaken and metrics employed by the PIC to verify that sensors operate within manufacturers specifications.

Procedures:

All sensors returning from a field experiment are subject to the following procedures:

EPIC Intern Spends Summer on the Ice

EarthScope/EPIC summer intern Alan Shi has some interesting stories to tell about his last few months with the EPIC in Socorro, NM.  The season began calmly enough, and Alan enjoyed developing a testing enclosure to verify that field equipment boxes such as the MEVO (Mt. Erebus Volcanic Observatory) boxes were distributing power properly, as well as performing ruggedness-testing of memory sticks before their use to collect data in arctic regions. But, the most impressive part of Alan's summer by far was his deployment to the rapidly-changing ice sheets of Greenland.  Here are some recollections and photographs of intern Shi's experiences on the ice.

 

EarthScope EPIC Presentations at the Seismological Society of America 2014 Meeting

Instrument Use Policy

Sept 12, 2006 INTRODUCTION

Portable field recording equipment and field computers purchased by the EPIC Program are available to any research or educational institution to use for research purposes within the guidelines established in this document. The intent of these guidelines is to establish the procedures to enable investigators to request the instruments, to let them know what requirements and responsibilities are incurred in borrowing the equipment and to know when and how the decisions on instrument allocation will be made.

EPIC Posters at 2014 EarthScope Workshop, June 8-11, in Sunriver, Oregon

EarthScope EPIC Supports Fluvial Seismology Research in Grand Canyon

When and how do rivers transport sediment from eroding landscapes? New research by Brandon Schmandt and Karl Karlstrom of the University of New Mexico and Rick Aster of New Mexico Tech is shedding light on how seismology can address this fundamental problem. The EPIC provided several quick-deploy stations from its RAMP (Rapid Array Mobilization Program) pool in support of this innovative project. The panoramic view of the Grand Canyon above was taken during a December 2012 data recovery trip.

EarthScope/EPIC Intern Cuts Her Teeth on TESGM Project Fieldwork

EarthScope/EPIC summer intern Jennifer Tarnowski is learning the ropes of a seismology career by working at the EPIC at New Mexico Tech, and also by participating with hands-on efforts in the field.  Jennifer recently participated in fieldwork supporting the Topographic Effects in Strong Ground Motion project (TESGM, EPIC project 201109) in early July, along with principal investigators Brady Cox,  University of Arkansas, Adrian Rodriguez-Marek, Virginia Tech., graduate student Clinton Wood, University of Arkansas, Robert Kent of the Network for Earthquake Engineering Simulation (NEES), and Steve Azevedo, EarthScope/EPIC.

Batholiths Onland 2009

In July 2009, several EarthScope/EPIC scientists assisted with the Batholiths Onland project. This large group effort involved over 50 scientists and grad students, for the purpose of making "a seismic refraction and wide-angle reflection survey across the Coast Mountains batholith of British Columbia, Canada."
