UNAVCO Community Science Shared with NSF Director

March 30, 2015

On February 20, 2015 NSF Director Dr. Frances Córdova and other NSF leadership met with UNAVCO President Dr. M. Meghan Miller at the NCAR Research Aviation Facility at Rocky Mountain Metropolitan Airport in Broomfield, Colorado. The senior management team, select UNAVCO staff, and several early career scientists joined them.

Low-Cost Additions to the Plate Boundary Observatory for Earthquake Early Warning

Low-Cost Additions to the Plate Boundary Observatory for Earthquake Early Warning

March 30, 2015

Between December 2014 and February 2015, UNAVCO installed 10 accelerometers at existing Plate Boundary Observatory (PBO) GPS sites in the San Francisco Bay Area. Accelerometers in combination with high-precision GPS data provide a new interdisciplinary data type. Applied in real-time, this information is an essential input in models for prototype earthquake early warning systems.

UNAVCO installs COCONet cGPS site CN01 and upgrades sites BGGY and CN00 in Antigua and Barbuda

February 23, 2015

During this installation and maintenance trip, UNAVCO collaborated with the Antigua and Barbuda National Office of Disaster Service (NODS), University of the West Indies (UWI) Trinidad, and the US Geological Survey (USGS) to install a new station and maintain two others.

Plate Boundary Observatory as a Hydrological Network to Monitor Drought

Plate Boundary Observatory as a Hydrological Network to Monitor Drought

September 18, 2014

The Plate Boundary Observatory in the western United States consists of more than 1,100 continuously operating GPS stations deployed to record the Earth’s surface response to tectonics. Now the network is being used as a hydrological monitor. This study shows that the western U.S. lost about 240 gigatons of water in 2013-2014. The observatory is a sensitive hydrological monitor that can help manage water resources.

Dynamic Rupture Model for the 2010 Haiti Earthquake

Dynamic Rupture Model for the 2010 Haiti Earthquake

March 30, 2015

The 2010 magnitude 7.0 Haiti earthquake occurred on a secondary blind thrust fault, the Léogâne fault, rather than on the Enriquillo-Plantain Garden fault (EPGF). The best-fitting model simulation shows that the rupture did not trigger the EPGF or the Trois Baies fault, but there has been significant stress buildup on these faults, so future risks should be considered.

Detecting Volcanic Plumes with GPS Data

Detecting Volcanic Plumes with GPS Data

July 26, 2013

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.

Ice Mass Loss on North Antarctic Peninsula Linked to Fluid Upper Mantle

Ice Mass Loss on North Antarctic Peninsula Linked to Fluid Upper Mantle

February 23, 2015

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.

Sea Level Rise on the U.S. Gulf Coast

Sea Level Rise on the U.S. Gulf Coast

February 6, 2013

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.

Mapping the Seafloor with Gravity Models

Mapping the Seafloor with Gravity Models

February 18, 2015

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.
