Russian GLONASS Global Navigation Satellite System April Outage and UNAVCO

Russian GLONASS Global Navigation Satellite System April Outage and UNAVCO

December 15, 2014

The Russian GLONASS Global Navigation Satellite System experienced a ten-hour outage beginning at 21:00 UTC on April 1st, 2014 that affected a significant number of GNSS receivers operated by UNAVCO and our collaborators.

UNAVCO installs COCONet cGPS site CN18 on Swan Island Honduras

December 05, 2014

COCONet cGPS site CN18 was installed on Swan Island, Honduras, and is poised to collect particularly valuable atmospheric and geodetic data because it will provide coverage in a remote part of the world with little data availability.

Workshop on Future Seismic and Geodetic Facility Needs in the Geosciences

Workshop on Future Seismic and Geodetic Facility Needs in the Geosciences

December 01, 2014

A 2 1/2 day workshop will be held May 4-6, 2015 to gather community input for the National Science Foundation on the most important scientific questions, research opportunities, and broader impacts that the community will be pursuing in 2018 and beyond, and the seismic and geodetic facility capabilities that will be required to support this research and associated education, outreach, training and workforce development.

Reaching kids and their parents through hands-on science

Reaching kids and their parents through hands-on science

November 20, 2014

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. This event is organized by the University Corporation for Atmospheric Reseach (UCAR), and is free and open to the public.

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.

Rifting in Eastern Africa: Geodetic Data Deciphers Spreading Forces

Rifting in Eastern Africa: Geodetic Data Deciphers Spreading Forces

October 7, 2014

The driving forces of the East African Rift System are deciphered by modeling GPS and seismic data of present-day rifting. The models show that density variations within the lithosphere, causing gravitational potential energy (GPE) gradients are driving the current plate spreading in East Africa.

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.

Unrecognized Rapid Ice Loss in Northeast Greenland Due to Warming

Unrecognized Rapid Ice Loss in Northeast Greenland Due to Warming

May 13, 2014

The ice stream in northeast Greenland shows rapid ice loss because of rising air surface temperatures and the loss of sea ice, which is associated with rising sea surface temperatures. The thinning glaciers are detected by a combination of satellite and aerial imagery plus GPS measurements of ground surface rebound due to rapid ice mass loss. Models do not predict the northeast sector of the continent to show such melting with consequences for under-estimating sea level rise.

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.

Estimating plate boundary slip during large earthquakes: seafloor geodesy during 2011 Tohoku-oki Earthquake in Japan

Estimating plate boundary slip during large earthquakes: seafloor geodesy during 2011 Tohoku-oki Earthquake in Japan

September 1, 2012

The forces of the Japanese Tohoku-oki 2011 magnitude 9.0 earthquake, the fifth most powerful in the past century, set off a large tsunami that further devastated the shaken island. The earthquake and tsunami also badly damaged a six-reactor nuclear power plant in Fukushima, located 241 kilometers north of Tokyo.

Quality Assessment: A new technique to assess and monitor long-term quality of GPS data

March 7, 2013

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.
