SSBW - IRIS DMC Tutorial 2: GMAP, MDA, and MUSTANG Databrowser
In this interactive tutorial built for a learning management system, students will 1) use the IRIS GMAP Station Browser to identify what seismic stations have data available based on a geographic region, a time frame, and a type of recording, 2) use the MetaData Aggregator to explore what type of data is available at a given station or network, and 3) use the MUSTANG tools to investigate the quality of data stored.
The IRIS Seismology Skill Building Workshop (SSBW), which is a free, online, open-access, large-enrollment, 12-week summer workshop for upper level undergraduates.
Skills and concepts that students must have mastered
This assignment builds on prior understanding of seismometers, seismograms, and structure of the earth.
How the activity is situated in the course
This is assignment number 15 of 35 in the Seismology Skill Building Workshop (SSBW).
Content/concepts goals for this activity
Proficiency with metadata, station availability, IRIS metadata tools, types of seismic recordings, styles of seismic networks.
Higher order thinking skills goals for this activity
Retrieving relevant information from digital sources to accomplish tasks, using correct programming syntax, evaluating and describing computing output in the context of science concepts.
Other skills goals for this activity
Description and Teaching Materials
1. Read about metadata, the GMAP Station Browser, and the MetaData Aggregator (MDA)
2. Use the GMAP tool to identify what seismic stations have data available through IRIS based on a geographic region, a time frame, and a type of recording
3 . Use the MDA tool to explore what type of data is available at a given station or network and the duration of recordings available.
4. Read about MUSTANG (Modular Utility for STatistical kNowledge Gathering) web services
5. Use the MUSTANG tools to investigate the quality of data stored at IRIS and determine how much seismic data is available using a line graph
Teaching Notes and Tips
