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
Accessible Earth: Innovative Field Course Increases Options and Accessibility to Geoscience Overview Current trends in US demographics, rising costs of higher education, and hurdles to entry and retention of first-generation students seriously threaten our ability to mitigate future workforce shortages across STEM fields, with geosciences among the least diverse and most at risk. At the … 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
Unoccupied aerial systems (UAS) show promise for accurately surveying penguin populations in Antarctica. Two UNAVCO-supported UAS surveys of Adélie penguins this season (2018-19) will lend insight into penguin nesting habits. The first took place in early December 2018 with a key goal of counting the nesting adults. The second was timed with the chick counts … Continued
Overview Slumgullion landslide, in southwest Colorado near Lake City, is an ideal outdoor laboratory for comparing a variety of techniques used to measure slope displacements and understand landslide kinematics. The “slow” landslide is nearly constantly active, with surface displacements of several centimeters per day measured on some areas of the slide surface. The goal of … 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
Upgrade to a Global Network: Maintaining the NASA GGN Overview UNAVCO, in collaboration with the NASA Jet Propulsion Laboratory (JPL), is responsible for the operations and maintenance of the 57 permanent GNSS stations that make up a large portion of the NASA Global GNSS Network (GGN) (Figure 1). The GGN is NASA’s contribution to the … 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
Overview Determining how the Caribbean plate moves with respect to the neighboring North America and South America plates has been a major challenge. Geologic plate motion models using seafloor magnetic anomaly rates, transform fault azimuths, and slip vectors are challenging due to sparse data. The only rates come from the Cayman Spreading Center, and seismicity … Continued
