We challenge ourselves to transform human understanding of the changing Earth by enabling the integration of innovative technologies, open geodetic observations, and research, from pole to pole.

UNAVCO hosts three summer internships, each with a different focus: Research Experiences in Solid Earth Science for Students (RESESS), Geo-Launchpad, and the UNAVCO Summer Internship Program (USIP).

In collaboration with the government of Anguilla, UNAVCO installed COCONet cGPS station CN51 on Sombrero Island in May 2015. CN51 increases coverage on the northern edge of the Caribbean plate and is the northeasternmost station in the network.

In response to the Mw 6.7 Alaska earthquake on May 29, 2015 at 07:00, one-sample-per-second (1-sps) GPS data will be collected for a 7-day period around the event (day of event ± 3 days). Once downloaded, data will be available from ftp://data-out.unavco.org/pub/highrate/.

Despite day after day of rain in California's drought, 15 students of various majors are traipsing around the desert in Indiana University's Volcanoes of the Eastern Sierra intro-level field course. The course is led by UNAVCO community member Michael Hamburger and is still going strong after 13 years. UNAVCO supports the class with staff and equipment.

Eight years of observations of millimeter-level vertical surface changes from a dense network of Global Positioning System (GPS) receivers in the Pacific Northwest tracks a fluctuating water load due to varying precipitation. The observations track seasonal variations (i.e., more rain or snow in the fall and winter) and the drought of 2008-2010.

Intrusive unrest at Bárðarbunga Volcano in Iceland in 2014 shows segmented lateral dike growth creating new crust where the tectonic plates separate.

GPS data were used to detect volcanic plumes from eruptions of Mount Redoubt in Alaska. Unlike past research, this study relied on the signal strength, or signal to noise ratio (SNR), data. The new method is powerful because simple models can be used to quickly model SNR data and the SNR data are not sensitive to water vapor.

The North Antarctic Peninsula (NAP) has lost significant ice over decades and the amount and rate of land rebound as the ice is removed can be used to decipher the structure of the crust and upper mantle. Using vertical motion of the land recorded at the Palmer GPS site since 1995, augmented with other GPS data and a simple four-layer model yields a thicker crust and a more fluid upper mantle than expected.

The Mississippi Delta along the Gulf Coast of the United States is a major site of sediment deposition from the Mississippi River and conversely a major site of wetland loss from rising seas and subsidence. There is debate about how much and when the delta has risen or fallen due to deposition, subsidence, sea level change, and erosion.

Most of the ocean floor is unknown. Gravity models generated from satellite radar altimetry provide one of the only ways to map the height of the seafloor beneath all of the oceans. Years of data and thousands of satellite tracks have yielded unprecedented detail of major spreading ridges and thousands of seamounts.

Geoff Blewitt and Corne Kreemer of UNR’s Geodetic Laboratory have devised a new processing-based technique for evaluating site quality on an ongoing basis.
