Project 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 … Continued
Project Overview UNAVCO provided an engineer and TLS equipment to assist with the UC Santa Cruz field camp this past summer in the Eastern Sierra Nevada. Each year, geology undergraduates from the university stay at the Sierra Nevada Aquatics Research Lab (SNARL) for one week as part of their six-week-long field camp, dedicated to familiarizing … Continued
Project Overview The International Tundra Experiment (ITEX) network has collected data on phenology, plant growth, community composition, and ecosystem properties as part of a greater effort to study environmental Arctic change. The network has played a key role in advancing knowledge related to the likely impacts of a warmer Arctic through the use of experimentally … Continued
Project Overview GPS data continues to provide key clues to the Caribbean region’s geologic faults. GPS stations are currently being installed as part of the Continuously Operating Caribbean GPS Observational Network (COCONet), strengthening the indispensible collection of data belonging to a region that faces many atmospheric and geologic natural hazards. UNAVCO Connection With assistance from students … Continued

Project Overview The Continuously Operating Caribbean GPS Observational Network (COCONet) was recently expanded with the installation of a new GPS station on the island of Trinidad. This island is the lowest latitude landform of the West Indian island arc chain, and the new station now marks the most south easterly boundary of COCONet. However, two … Continued
Project Overview In 2006, while collecting samples of rock, Bucknell University researchers Craig Kochel and Rob Jacob discovered landforms in the Wrangell Mountains of Alaska that had previously been uncharacterized. These newly discovered landforms were named icy debris fans due to similarities with alluvial fans. An alluvial fan is a fan- or cone-shaped deposit of … Continued

Project Overview Puerto Rico and the northern Virgin Islands define the eastern terminus of the Greater Antilles, which extend eastward from offshore eastern Central America to the Lesser Antilles volcanic arc and mark the boundary between the Caribbean and North America plates. In Hispaniola, Puerto Rico, and the northern Virgin Islands, the Puerto Rico trench … Continued
Project Overview UNAVCO staff installed 3 new COCONet continuous GPS/MET sites in Panama, which complement the previously installed CN33 (ca. November 2011) continuous GPS/MET site. A total of 4 new COCONet cGPS and meteorological sites (CN20, CN28, CN33, and CN34) are now operational in Panama. In addition, COCONet is receiving continuous GPS data from four … Continued
