Improving Our Understanding of Carbon Sequestration Monitoring with GPS |
Tim Dixon of the University of South Florida is working to develop a new, integrated approach for monitoring, verification, and accounting of carbon dioxide (CO2) sequestered in deep geologic repositories. Interest in terrestrial carbon sequestration has increased in an effort to explore opportunities for climate change mitigation. Read more |

COCONet GPS Network Expansion: Colombia |
In August and September of 2012, UNAVCO supported the installation of four new cGPS stations in Colombia as part of the ongoing COCONet installation phase. Three of the new sites are located along the northern coast of the country and one site is on the island of Providencia (belonging to Colombia), situated 140 miles off of the eastern coast of Nicaragua.

The BanglaPIRE Project: Exploring the geologic and hydrologic processes that shape the Bangladesh region |
Three of the world’s largest rivers, the Ganges, the Brahmaputra, and the Meghna, converge in the country of Bangladesh and dump one gigaton of sediment there annually to form the world’s largest delta (The Ganges-Brahmaputra-Meghna Delta, or GBMD). This delta overlies the rapidly subsiding junction of three tectonic plates. Read more |

PBO Data and Preliminary Ground Motion Measurements from the August 2012 Brawley, California Seismic Swarm |
A seismic swarm near Brawley, CA, south of the Salton Sea, began on August 26, 2012, at 04:30 GMT (August 25, 21:30 PDT). Over 500 events were recorded by the Southern California Seismic Network by August 29. The two largest earthquakes in the swarm were a M5.3 at 19:31 August 26 (12:31 PDT) and a M5.5 at 20:57 August 26 (13:57 PDT). Many of the events were reported felt across much of southern California. The town of Brawley is located less than 5 km (3 miles) from the swarm, and minor damage was reported. Read more |

Community Geophysical Event Response to the 5 September 2012, Mw=7.6 Nicoya Peninsula, Costa Rica Earthquake |
On Wednesday, September 5, 2012, at 14:42:07 UTC, a magnitude 7.6 earthquake struck roughly 40 km (25 miles) below the surface of the Earth, 10 km (6.2 miles) ESE of the city of Nicoya, Costa Rica. This earthquake occurred beneath the Nicoya Peninsula of Costa Rica as the result of thrust faulting on the subduction zone interface between the subducting Cocos and overriding Caribbean plates.

TLS survey campaign of Thrihnukagigur Volcano, Iceland |
In late June of 2012, UNAVCO provided continued support for Dr. LaFemina with a second TLS survey campaign in Iceland. A Leica C10 scanner was used to scan the inner chamber, shaft and surrounding area above the Thrihnukagigur Volcano. Over the course of 7 days, 18 scan positions were occupied and over 500 million points collected. In comparison, previous surveys of the magma chamber using land-surveying equipment produced only 1200 points. Read more |

Glaciological dynamics of a debris-covered alpine glacier using Terrestrial Laser Scanning: Potential impacts for water resources and natural hazards |
As part of ongoing research that seeks to understand the implications of glacier retreat at Volcán Chimborazo, Ecuador, researchers from Ohio State University are attempting to quantify both the rate and extent of glacier retreat on the mountain in recent years. Read more |

Hydrology at the Base of the Greenland Ice Sheet |
What role does water play in the movement of the vast Greenland Ice Sheet? This integrated measurement and modeling project is a comprehensive investigation of this very question. Conditions at the base of the glacier will be directly measured in six boreholes drilled to the bed, with two holes at each of three sites. Surface melt and spatial gradients in ice velocity will be quantified to enable detailed comparison between melt water forcing, basal hydrologic conditions, and ice flow dynamics. Read more |

The Polar Earth Observing Network (POLENET) 2011/2012 Field Season |
The POLENET (Polar Earth Observing Network) project focuses on collecting GPS and seismic data from autonomous systems deployed at remote sites spanning much of the Antarctic and Greenland ice sheets. GPS and seismic measurements together provide a means to answer critical questions about ice sheet behavior. Read more |

Nicoya Peninsula continuous GPS network telemetry upgrades and COCONet network expansion |
The Nicoya Peninsula continuous GPS network consists of 18 remote sites distributed mostly in the forearc of the Cocos subduction zone in northwest Costa Rica. The network is designed to measure transient surface deformation above the seismogenic plate-boundary interface. The network was established and expanded in several stages beginning in 2006.

Installation of Two Deep Drilled-Braced Monuments and One Short Drilled-Braced Monument at The Goddard Geophysical and Astronomical Observatory |
In 2011, a collaborative NASA-funded Space Geodesy Project was initiated. Jointly operated by the NASA Goddard Space Flight Center and Jet Propulsion Laboratories, the project is focused on constructing, operating, and maintaining a NASA Space Geodetic Network (NSGN) of integrated, multi-technique next generation space geodetic observing systems.
