Reaching kids and their parents through hands-on science Each fall at Super Science Saturday, hundreds of children and their adult escorts descend on Boulder, CO’s NCAR Mesa Lab to learn about science through fun hands-on activities. Super Science Saturday provides UNAVCO an opportunity to participate in a local outreach event in a community we’ve been a part of for 30 years, and to teach kids how to use a familiar technology—GPS, one of UNAVCO’s specialties—to learn about their world and be scientists.

Free and easy access to online geodetic data: using Digital Object Identifiers (DOIs) for UNAVCO data and metadata Free and open access to scientific data is pivotal to the success of geoscience research worldwide. Digital object identifiers (DOIs) allow data sets to be uniformly cited, making it easier for researchers to find the original source of data in publications and for UNAVCO and the researchers we support to be properly acknowledged.

Monitoring Erosion on a Volcano: High Resolution Topographic Surveys of Mauna Kea, HI Mauna Kea, a dormant 13,800 foot tall volcano on the Big Island of Hawaii, is experiencing substantial natural and human-caused erosion at its summit. UNAVCO is helping Ryan Perroy of the University of Hawaii, Hilo to monitor these erosion rates by providing a baseline high-resolution topographic map of the summit area to quantify natural and anthropomorphic influences. This project will help to establish a habitat suitability model for the Wekiu bug, a rare endemic invertebrate species that is only found on Mauna Kea.

Data event response to the 14 October 2014 Mw 7.3 earthquake 67km WSW of Jiquilillo, Nicaragua In response to the Mw 7.3 earthquake 67km WSW of Jiquilillo, Nicaragua on October 14, 2014, UNAVCO is downloading high-rate GPS data from a total of 25 stations within 1,000 km of the epicenter (Figure 2). One-sample-per-second (1-sps) GPS data were collected for a five-day period around the event (day of event plus two days before and after). Five-sample-per-second (5-sps) GPS data, where available, will also be collected for a 12-hour period (± 6 hours) around the event. These data are available from ftp://data-out.unavco.org/pub/highrate/.

Data Event Response to the 25 September 2014 Mw 6.2 Earthquake 94km WNW of Willow, Alaska The Alaska Earthquake Center located a strong earthquake that occurred on Thursday, September 25th at 9:51 AM AKDT in the Cook Inlet region of Alaska. This earthquake had a preliminary magnitude of 6.2 and was located at a depth of about 64 miles (103 km). As a response, UNAVCO is downloading one-sample-per-second (1-sps or 1 Hz) data from GPS stations within an approximately 100 km radius of the epicenter, as well as from stations near Anchorage, where shaking was felt.

Maintaining POLENET Sites from the South Pole The POLENET Antarctic Network (ANET) has produced a valuable dataset of GPS and seismic measurements since 2007. These sites endure some of the harshest weather conditions on the planet, and consequently many must be visited at least every two years. The South Pole provides an ideal logistical hub for servicing geophysical stations that are up to 400 miles away.
