Near-Trench Community Geodetic Experiment
A five year NSF-funded project that will establish open and accessible seafloor deformation data offshore Alaska and Cascadia, in regions responsible for some of the largest earthquakes and tsunamis ever recorded.
New software, data, and training will prepare next-generation Earth scientists!
Six new sites are planned here near the rupture area of the 1946 'tsunami earthquake', the southern extent of the 1964 Magnitude 9.2 Good Friday earthquake (2nd largest ever recorded), and complimenting existing sites in between.
Installation is planned for summer 2023.
Six new sites are planned along the rupture area of the 1700 (expected magnitude about 9) earthquake responsible for large tsunami waves as far away as Japan. These sites represent a range of expected coupling behaviors using on-land data, and compliment existing and planned US and Canadian sites.
Installation of new sites started in 2022 as a part of commissioning of the SGIP, and will continue through 2023.
Project will oversee the development of open-source code for the processing of GNSS-Acoustic data for seafloor horizontal positioning.
Two short-courses for "Data Processing" are planned that will utilize the newly developed software for working with available community data. Courses will prioritize graduate students and postdocs.
Two short-courses are planned for "Future PIs" that will develop understanding of opportunities and limitations of current tools, ship-time requests, network design, and cooperation with local and international partners.
All community experiment data will be openly available and following FAIR standards through the GAGE facility currently operated by UNAVCO.
Seagoing opportunities are planned for students, post-docs, and early-career scientists along each of the deployment, recovery and any repair legs where instruments are going to the seafloor. Announcements will appear shortly after determination of follow-year ship schedules.
