CYBERINFRASTRUCTURE FOR THE GEOSCIENCES UNAVCO/GEON PoP Access to UNAVCO/GEON resources provided via the GEONgrid Portal
CYBERINFRASTRUCTURE FOR THE GEOSCIENCES UNAVCO/GEON PoP Provides Custom GEON Access to UNAVCO Resources Data Metadata Software Visualization Geon research Education and Outreach 5-node cluster Partner Projects Chronos CUASI NASA 1TF cluster Livermore PoP node Partner services USGS Geological Survey of Canada ESRI UNAVCO POP
CYBERINFRASTRUCTURE FOR THE GEOSCIENCES Data Access Methods Data Meta- Data Current Access Methods: http and ftp (e.g. GPS Seamless Archive, GSAC, webpages) OPeNDAP (e.g. IDV 3D Visualization) Under consideration: ODBC/JDBC SRB Arcxml Gridftp GML SCP UNAVCO/GEON PoP
CYBERINFRASTRUCTURE FOR THE GEOSCIENCES 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: 1.The GSAC Wizard is a web-based client. 2. The GSAC command-line client. GSAC Retailer: 1.Gathers metadata and file locations from wholesalers 2.Organizes data into a POSTSQL relational database (same as GEON) 3.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
CYBERINFRASTRUCTURE FOR THE GEOSCIENCES UNAVCO/GEON OPeNDAP Server Unidata OPeNDAP software Unix binaries Some OPeNDAP Server Software: -Free Form -netCDF -IDL -Matlab UNAVCO/GEON OPeNDAP Server - Seismic Tomography, Global Strain Rate, Geodynamic Models, Earthquakes -NetCDF format -GPSVel vectors -Free Form ASCII data OPeNDAP data connector IDV Visualization Web browser -Data preview -Data download Free form GPS vectors
CYBERINFRASTRUCTURE FOR THE GEOSCIENCES IDV Visualization An example of an end-to-end solution: data/models -> NetCDF -> OPeNDAP server -> Visualization & Collaboration (developed by UNIDATA using U. of Wisc. VISAD) Color contours of the second invariant of the strain rate tensor (blue to red show low to high strain rate). Blue arrows indicate global plate motion from with respect to the North American Plate. Results are from the UNAVCO-supported Global Strain Rate Map (GSRM) project (Kreemer, et al. 2003). Isosurfaces of 5% positive S-wave anomalies (green surfaces) in the upper mantle from a global tomographic model of Ritzwoller, et. al The higher velocity regions are typically associated with colder denser regions underlying continental interiors such as the Canadian shield. All data from the above figures shown together with a color contour surface of the S-wave anomalies at 100 km depth. The IDV has powerful capabilities to show integrated views of volume and surface data. There is a clear correlation between areas of high strain rate and low S-wave velocities in the upper mantle under W. North America and the east Pacific rise
CYBERINFRASTRUCTURE FOR THE GEOSCIENCES Data Visualization Example: Mantle Tomography with IDV Metadata embedded in NetCDF file is returned from the OPenDAP Server in response to URI Example data on UNAVCO/GEON node and IDV xml configuration files simplify getting started with the IDV
CYBERINFRASTRUCTURE FOR THE GEOSCIENCES IDV Visualization Mantle 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: "~ 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" location: "Department of Physics at University of Colorado at Boulder, Campus box 390 Boulder Co, USA" website: "http://anquetil.colorado.edu/szhong" Mantle Temperature

CYBERINFRASTRUCTURE FOR THE GEOSCIENCES UNAVCO/GEON Rocky Mountain Research GRA 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.
CYBERINFRASTRUCTURE FOR THE GEOSCIENCES 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.
CYBERINFRASTRUCTURE FOR THE GEOSCIENCES 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
CYBERINFRASTRUCTURE FOR THE GEOSCIENCES Related Activities: Yellowstone 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. The Yellowstone Volcanic System Database Bob Smith and Jamie Farrell, Univ. of Utah …See Poster!
CYBERINFRASTRUCTURE FOR THE GEOSCIENCES Yellowstone Tomography viewed with the IDV Shear wave topography of the Yellowstone plateau. The IDV allows the user to make cross- sections, probe the data, and to make 3-D isosurfaces of constant velocity anomaly. From M. Jordan and R. Smith, U. of Utah
