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.

This marks the fifth year that UNAVCO has sent both a real-time-kinematic GPS system and a field engineer to assist with the GPS portion of a Volcanoes of the Eastern Sierra Nevada field course.

Aisha R. Morris is excited to join the UNAVCO team as an Education and Community Engagement Specialist, and Director of the RESESS Program. Most recently, Aisha worked in the office of Representative Rush Holt (NJ-12) as the 2011-2012 William L. Fisher Geosciences/American Association for the Advancement of Science (AAAS) Congressional Science Fellow.

With assistance from the Anguillan government, UNAVCO installed a continuous GPS/MET site in Anguilla, one of the most northerly of the Leeward Islands in the Lesser Antilles, lying east of Puerto Rico and the Virgin Islands, and directly north of Saint Martin.

Puerto Rico and the northern Virgin Islands define the eastern terminus of the Greater Antilles, which extend eastward from offshore eastern Central America to the Lesser Antilles volcanic arc and mark the boundary between the Caribbean and North America plates.

The damaging March 11, 2011 Tohoku earthquake caused significant tsunami waves that were recorded on videos by eyewitnesses. Two survivor videos from building rooftops at Kesennuma Bay were combined after the catastrophe and compared with on site terrestrial laser scans, using ground-based LiDAR.

The many tectonic plates that make up the surface of the Earth giving us mountains, earthquakes, volcanoes, coastal plains, seamounts, mid-ocean ridges and other features are tied to flow in the deeper mantle.

A coronal mass ejection (CME) from the Sun that was directed toward the Earth created a significant ionospheric and geomagnetic disturbance at the South Pole. Observations from satellites, the Antarctic GPS network and seven GPS scintillation receivers installed in 2010 mapped out the disturbance.

Snow and ice melts in Greenland every summer, but the summer of 2010 melting season was so much longer and hotter than in previous years that an extra 100 billion tons of ice melted from the ice sheet and flowed out to sea.

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.

UNAVCO’s Plate Boundary Observatory includes 75 borehole strainmeters installed predominantly throughout the west coast of North America. Strainmeters work by detecting changes in the size of the borehole, and are sensitive enough to detect a 4 picometer change (smaller than the width of a hydrogen atom). Because they are so sensitive, they pick up every thump and shake in their vicinity, including the arrival of a tsunami wave from across the ocean.

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.
