Transportable Array

Overview

The Transportable Array (TA) is a gridwork of broadband seismic instruments that are being installed across the continental United States (see a map of TA stations that have been installed to date).  They are laid out in a rectangular array with approximately 75 kilometer spacing between stations stretching from Canada to Mexico and from the Pacific Ocean eastward.

EPIC USER Workshop Pre_AGU Fall 2010

EPIC User Workshop : PRE-AGU - San Francisco December 12th 2010

Hello Dear Participants

We are excited with the great response we got from you all about our second workshop in San Francisco. During this workshop, we would like to focus our efforts  on providing an overview of the EPIC facility to young investigators, anyone with upcoming EPIC supported experiments or plan to submit a proposal to the National Science Foundation using EPIC equipment and support.

Passcalians Attend AGU Fall Meeting

The annual Fall Meeting of the American Geophysical Union is one of the largest and most interesting scientific conferences in the world. Some 15,000 scientists - from students to professional researchers, from small environmental analysis groups to huge government entities like NASA and NOAA - and a small troop from EarthScope - gathered at the Moscone Center in downtown San Francisco for a week in mid-December 2009 to share their studies and recent results with each other, and with anyone curious enough to listen in.

Flexible Array experiment researchers brave alligators in the name of seismology!

 

The alligator photographed guards SESAME's station E22.  Locals report the alligator likely made a short traverse through the forest from a nearby river, where alligators are commonly spotted, to call the pond home.

USArray

The Flexible Array is a pool of portable seismic instruments supported by the Array Operations Facility at the EPIC. The instruments are available for PI-driven research projects associated with the goals of Earthscope. The pool consists of broadband (325), short-period (100), accelerometer (20), and controlled source (1700) stations.

SEG-Y: What is it?

The Society of Exploration Geophysicists Y Format, or SEG Y, has been the accepted exploration industry data format for digital seismic data since 1975.  Originally a magnetic tape-centric format, SEG Y has evolved over the years to remain the data format industry standard for data analysis and processing.  The latest revision (revision 1 .pdf format) to the format was released in 2002. 

SEG-Y files produced from PH5 data sets

 

The SEG-Y file written by ph5toseg is in big endian byte order and attempts to follow the SEG-Y rev 1 standard (May 2002) as outlined in the table below.

The file does not contain a Tape Label.
