gps seamless archive gsac
GPS Seamless Archive (GSAC)
  • The GSAC helps you locate GPS data files which are archived at different GPS Data Archive Centers from a single user interface.
  • GSAC Clients:
  • The GSAC Wizard is a web-based client.
  • 2. The GSAC command-line client.
  • GSAC Retailer:
  • Gathers metadata and file locations from wholesalers
  • Organizes data into a POSTSQL relational database (same as GEON)
  • Provides services to GSAC Clients

GEON “Instance”

Of GSAC Retailer

GSAC developed by Scripps and UNAVCO

The GSAC will be the primary means of GPS raw data and data product discovery and access for EarthScope

Data VisualizationExample: Mantle Tomography with IDV

Example data on UNAVCO/GEON node and IDV xml configuration files simplify getting started with the IDV

Metadata embedded in NetCDF file is returned from the OPenDAP Server in response to URI

idv visualization mantle geodynamics convection with geologic plate motions over 120 m a
IDV VisualizationMantle Geodynamics: Convection with geologic plate motions over 120 m.a.

Purpose: "resolving multiple scale (both temporal and spatial) physics in mantle convection and lithospheric deformation"

scale: "whole mantle with plates"

resolution: "~40-50 -km, spherical geometry"

method: "Numerical (finite element)"

material_properties: "temperature and depth dependent viscosity (linear, no elasticity)"

code: "CitcomS [Zhong, Zuber, Moresi and Gurnis, 2000], 5000 time steps, over 4 million nodes!"

output: "normalized thermal and composition structure of the mantle from convection"

credits: "McNamara and Zhong (2004) - Allen McNamara and Shijie Zhong"

UNAVCO/GEON Rocky Mountain ResearchGRA Greg Bensen (UNAVCO, CU) with Prof. Anne Shehan (CU) and Prof. Randy Keller (UTEP)
  • Colorado seismology
    • Working with Rocky Mountain Front seismic data
    • Formatting database, locating local events (Colorado), calculating source mechanisms and stress drop.

www.geongrid.org

goals of rocky mountain research
Locations of local events will tell us about distribution of seismic hazards

Source mechanisms (~200 new events) show magnitude and direction of the state of stress

Will help to understand tectonics of the central Rocky Mountains

Resulting data will be used to experiment with new visualization and serving techniques using GEON resources.

New Analysis of Earthquakes in the Rocky Mountain region

Few Focal Mechanisms in existing Harvard CMT catalog…but earthquakes have occurred!

Greg Bensen is using data collected in the Rocky Mountain Front Passcal seismic experiment to determine locations and focal mechanisms for ~200 new events recorded with IRIS PASSCAL instruments

The Yellowstone Volcanic

System Database

Bob Smith and Jamie Farrell,

Univ. of Utah

…See Poster!

The purpose of the Yellowstone Volcanic System database is mainly two fold. The first is to integrate geographical, geological, and geophysical datasets into one large database. The second goal was to create an outlet for outreach and increased communication. Through this database web site, any researcher or lay person has access to the majority of Yellowstone related data at any time and virtually any place.
