Project Overview 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. Significance Almost 160 million … Continued
Project Overview COCONet (Continuously Operating Caribbean GPS Observational Network) is an NSF sponsored project with over 35 participating institutions from South, Central, and North America. COCONet will establish a network of over 50 new continuous GPS (cGPS) and meteorology stations, refurbish an additional 21 stations, and archive data from more than 60 cGPS stations that … Continued
Project Overview 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. This new NSGN will serve as … Continued
Project Overview 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. Many of … Continued
Project Overview 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. Determining the vertical and horizontal velocity fields … Continued
Project Overview UNAVCO provides geodetic support to NSF-OPP funded scientific investigators working in the Arctic and Antarctic. Survey grade GPS receivers, terrestrial laser scanners, and supporting power and communications systems for continuous data collection and campaign surveying are available. Operation and maintenance services are also provided for long term data collection, with on-line data distribution … Continued
Project Overview UNAVCO provided support for Dr. Ryan Ewing’s (University of Alabama) first TLS survey campaign to the White Sands National Monument. Scanning was carried out over the course of four days in three separate locations within the monument. Site access and project assistance were made possible by Dr. Ewing’s ongoing collaborator, David Bustos, White … Continued
Project Overview 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 … Continued
Project Overview 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. If successful, we will better understand the vulnerability of potential water resources … Continued
