Overview NASA’s Space Geodesy Project (SGP) was initiated in order to develop and maintain a global network of next-generation space geodetic observing instruments. Core sites around the globe will use three or four of the primary space-geodetic techniques: Very Long Baseline Interferometry (VLBI), Satellite Laser Ranging (SLR), Doppler Orbitography by Radiopositioning Integrated on Satellite (DORIS), … Continued
Overview Over two and a half weeks in June 2017, graduate student Gorki Ruiz from The Pennsylvania State University (PSU), Omar Espinoza and Javier Cornejo from Instituto Geografico Nacional “Tommy Guardia” – Departamento de Geodesia, and Mike Fend from UNAVCO traveled throughout much of Panama to collect episodic GPS data (eGPS) and service previously installed … Continued
Overview Cryoconite holes are pockets of life completely encased in otherwise barren glacial ice. These features are formed from when dust blown onto a glacier melts a small, largely isolated hole that can function as its own tiny ecosystem. This dust can contain microorganisms such as bacteria, algae, or microscopic animals. The microorganisms within the … Continued
Overview Terrestrial laser scanning (TLS) was used in project support of researchers from the University of Oregon refining sediment transport models in steep terrain. TLS yielded measurement densities of greater than one point per centimeter, enabling researchers to image tree throws, or the cavities left behind by a tree’s roots when the tree is upended. … Continued
Project Overview In August and September of 2016, the Chimney Fire burned through 46,000 acres of San Luis Obispo County near the central California coast. In addition to destroying dozens of homes and structures, the fire also swept over P278 Clarke Mountain, a GNSS station located on a high ridge within the burn zone. While … Continued
Project Overview The UNAVCO polar services team developed a power system for three radar systems in Greenland for the summer of 2016. The radar was to scan, multiple times a day, the calving front of Jakobshavn Glacier on the west coast of Greenland, near Ilulissat, and Helheim Glacier on the east coast of Greenland, near … Continued

Project Overview The National Geodetic Survey (NGS), an office of NOAA’s National Ocean Service, manages a network of Continuously Operating Reference Stations (CORS) that provide Global Navigation Satellite System (GNSS) data in support of positioning, meteorology, space weather, and geophysical applications throughout the United States, its territories, and several foreign countries (ref: CORS website). In September, … Continued
Project Overview This project came about quickly after the 3 September 2016, Mw 5.8, Pawnee, Oklahoma, earthquake. It is collaboration between the University of Memphis, University of Oklahoma (OU), and Oklahoma Geological Survey (OGS). The project deployed eight GPS stations around the causative Sooner Lake fault, in order to measure the years-long relaxation of the … Continued
Project Overview As part of the ongoing COCONet installation phase, one continuously operating GPS site was installed on Redonda Island in the West Indies of the Caribbean ocean. The island belongs to the nation of Antigua but its nearest neighbor is Montserrat, located 12 miles due southeast. Redonda is an uninhabited volcanic remnant characterized by … Continued
