Project Overview POLENET, a multiyear NSF-funded project, has entered its third award phase. The team for the 2018-19 Antarctic season, composed of six people, left McMurdo station for the remote field camp of WAIS Divide on December 13th, 2018. During the six-week deployment, the team installed five new GPS stations on the coast of Marie … Continued
CHORDS Provides Next Generation Infrastructure for Real-time Geoscience Data Services Overview The EarthCube Cloud-Hosted Real-time Data Services for the Geosciences (CHORDS) project aims to simplify access to real-time geoscience data. Through CHORDS portals, scientists can visualize data streams: (1) in samples/min/hour/day, (2) as simple time-series, and (3) via the time-series visualization software Grafana for real-time … Continued
Studying a Moving Target: Tracking Cryoconite Holes on Canada Glacier Overview Researchers from University of Colorado and Portland State University are using cryoconite holes on Canada Glacier, located in the McMurdo Dry Valleys, to study microbial communities in their natural environment. Cryoconite holes start as small, dirt-filled depressions on the glacier surface that melt into the ice, … Continued
Subduction Below Extreme Sedimentation: Multidisciplinary Transect from the Ganges-Brahmaputra Delta to the IndoBurma Backarc Overview UNAVCO has been supporting NSF-funded GPS observations in the Ganges-Brahmaputa Delta of Bangladesh since 2003. GPS position estimates collected from the deployed instruments have provided evidence that there is 13-17 mm shortening across this region per year. Initially, it was … Continued
Project Overview The Sierra Negra volcano on Isabella Island in the Galápagos Archipelago erupted spectacularly in 2005 with lava fountains reaching more than 200 meters high, and a gas/ash plume reaching 15 km altitude. Various types of data collected before, during and after that eruption gave earth scientists a better understanding of volcanic processes, some … Continued
Project Overview From February 12th through 16th, UNAVCO’s Dylan Schmeelk and John Galetzka joined UC Santa Cruz professor of Earth and Planetary Sciences Noah Finnegan (PI) and his graduate students Alex Nereson and Colleen Murphy in Oak Ridge in the mountains just east of Milpitas, CA to upgrade continuous GPS (cGPS) monitoring of the slow … Continued
Project Overview Over two weeks in April 2018, PhD student Gorki Ruiz from The Pennsylvania State University (PSU), Omar Espinoza (Sub-Director General), Javier Cornejo (Departamento de Geodesia) and Demetrio Garcia (Departmento de Cartografia) from Instituto Geográfico Nacional “Tommy Guardia” (IGNTG) / Autoridad Nacional de Administración de Tierras (ANATI), and Dylan Schmeelk from UNAVCO traveled throughout … Continued
Overview The NASA Jet Propulsion Laboratory (JPL) operates a global network of over 60 permanent GNSS stations called the Global Geodetic Network (GGN). UNAVCO offers support to the GGN by providing data flow monitoring, troubleshooting, station installation and maintenance, and engineering services to help improve the capabilities and performance of station infrastructure. In March of … Continued
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
