The UNAVCO, Inc. Plate Boundary Observatory (PBO) Student Field Assistant Program strives to engage students
in further study and careers in the Earth Sciences. Student Field Assistants from a variety of educational
backgrounds ranging from high school graduates to master's level students spend a three to five month field
season working in tandem with UNAVCO regional Field Engineers. The students work closely with senior staff to
reconnaissance, install, and maintain a network of 875 permanent Global Positioning System (GPS) stations in
one of the five PBO regions covering the western United States, including Alaska. Practical skills, such as power
tool use, drilling, welding, firearms training, and proper field safety procedures, are taught and expected of the
students. Installation and maintenance of new and existing GPS stations composes the bulk of the student's
responsibilities and duties. When not in the field, students prepare gear and arrange logistics for site
installations and maintenance as well as enter metadata and complete installation reports from recently
constructed sites. An understanding of the operations of the GPS receivers and the scientific benefit of the
network allows for an appreciation and great attention to detail during installation of the sites.
Student assistance in the Alaska region during 2007 PBO AK field season was critical to the successful
installation of 36 new GPS stations throughout Alaska. Significant benchmarks of the field season included
installing six logistically difficult stations in Prince William Sounds, completing the Denali Fault GPS network, four
new tiltmeters on Akutan Volcano, completing all installs on the Seward Peninsula as well as several new GPS
stations throughout the western interior of the state. Alaska is a prominent area for much movement and
deformation as the Pacific Plate subducts beneath the North American Plate resulting in an area of high volcanic
activity and heightened crustal deformation. The GPS network that is being constructed aims to better understand
much of these earth processes and their effects. To date, the Alaska Region has recently completed its 4th field
season and has installed 106 out of a planned 140 stations. During Year 5 of the PBO project, the Alaska PBO
regional office will complete the installation of all remaining 34 planned GPS stations including 12 stations on
Unimak Island. The 2008 field season will be the last year in the installation phase and will incorporate
maintenance of some of the first GPS stations installed in the network during the first and second years of the five
year project.
