Tanzania Volcano Observatory

Virginia Tech, Ardhi University, KIGAM

This is a CHORDS Portal for the Ol Doinyo Lengai, Tanzania Volcano Observatory.

• The scientific and societal objectives of the applications of CHORDS for this project are to:
• determine the role of active volcanism on tectonic fault slip during continental rift initiation.
• contribute to an informed volcanic hazards assessment for the Tanzanians in near real-time.

Detailed Information About CHORDS

CHORDS is supported by the National Science Foundation EarthCube initiative, which is a community-led cyberinfrastructure initiative for the geosciences.

You are looking at a CHORDS Portal. This is a web service that allows scientists to easily provide Internet access to real-time streaming data. Typically these data are measurements made by diverse instruments, which are deployed in support of a particular research effort.

Each research team can operate their own portal, which is created simply by running a copy of the CHORDS appliance on Amazon cloud services. This provides a web server and database. CHORDS can both ingest and deliver data via simple http: requests, just like any web browser. Configuration and management of your private CHORDS server is also done through a web interface. Any user on the Internet can attach to the data streams using tools of their choice, such as Matlab, Excel, Python, web browsers; i.e. anything that is able to issue an http: request.

CHORDS portals can also forward real-time data streams to higher level CHORDS services, which might provide functions such as OGC compliant formatting, mapping services, federation, and just about anything else you can think of.

The goals of CHORDS are:

• To lower the barrier for disemminating real-time geoscience observations via the Internet.
• To provide a simple, "shrink-wrapped" and inexpensive service that will be especially attractive to teams that do not have IT expertise and budgets.
• To provide standards-based interoperability with next level processing systems.
