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.

Visit our booth, attend an event, and keep up with UNAVCO work through our staff presentations at AGU 2015.

Connect UNAVCO is a new feature based on semantic web software that links geodetic services and products (such as, people, software, datasets, publications, and more) in efficient and discoverable ways.

UNAVCO has produced a fully processed 1-sps borehole strainmeter (BSM) dataset spanning the time period of this event.

Vertical motions measured by GPS ground stations can be used to track water loads related to precipitation in Ethiopia and Eritrea. The network monitors the seasonal East African monsoon and a smaller regional rainy season. The GPS network is an effective water monitor for the region, where most of the population is agriculture-based.

A global model that forecasts the rates of shallow, large-magnitude earthquakes is formulated by combining seismic and geodetic data. Over time, such models can be used by financial experts to develop a catastrophe bond market, providing opportunities for investors, the insurance industry and communities facing significant seismic risks.

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.

Combining geodetic and seismic measurements for the moderate 2014 Mw 6.1 Napa, California earthquake shows that rapid earthquake assessment is effective, so in a future real-time implementation, early responders will have more information to know where to concentrate their efforts to mitigate losses.
