PH5: Why Another Archival Data Format?



       The impetus to provide a new data format for archiving stems from the inherent limitations with respect to the use of SEG-Y as a data archiving format, limitations such as: requiring vetted meta-data prior to converting the data into SEG-Y files, un-editable meta-data within the file, and inflexible, static data gathers.

Hold on a minute... I want my data in SEG-Y format


All data requests of PH5 format data sets are fulfilled as either SEG-Y or PASSCAL SEG-Y.

Passive Source (SEED) Archiving Documentation

Main Documentation for PASSIVE Source Data Processing (SEED)

The documentation below offers instructions for archiving data from PASSCAL instrumentation in miniSEED format with metadata to be submitted as stationXML. To archive data from a PASSCAL experiment, select the appropriate documentation for your instrument for instructions for preparing the data before transferring it to PASSCAL. For the metadata, PASSCAL offers software for generating stationXML for your experiment. Please see the documentation for metadata generation using Nexus.

For PASSCAL PIs who previously archived data using Antelope, our documentation has been reworked to generate metadata in stationXML format via the PASSCAL program Nexus rather than using an Antelope database to create a dataless SEED. The documentation for archiving data with Antelope is still available on this page.

All about SEED format

SEED:  Standard for the Exchange of Earthquake Data

The Standard for the Exchange of Earthquake Data (SEED) is an international standard format for the exchange of digital seismological data.  SEED was designed for use by the earthquake research community, primarily for the exchange between institutions of unprocessed earth motion data.  It is a format for digital data measured at one point in space and at equal intervals of time.

The SEED reference manual (version 2.4) is published by the Federation of Digital Seismographic Networks (FDSN), the Incorporated Research Institutions for Seismology (IRIS), and the United States Geological Survey (USGS).

7th annual Polar Technology Conference coming to Albuquerque in March 2011

The 7th annual Polar Technology Conference will be hosted by IRIS/PASSCAL on 24-25 March 2011, at the Albuquerque Marriott, 2101 Louisiana Boulevard NE, Albuquerque, New Mexico 87110 USA. The primary purpose of this conference is to bring together Polar Scientists and Technology Developers in a forum to exchange information on research system operational needs and technology solutions that have been successful in polar environments.  This exchange of knowledge helps to address issues of design, implementation, and deployment for systems that are to achieve their research goals in the Polar Regions.
