Project Abstract
 In this project we aimed to increase GPS coverage and update GPS velocities in southern California by both resurveying sites that had not been measured in several years, and by identifying and surveying additional, existing benchmarks that had not previously been measured, but that could fill gaps in our network coverage. The project was designed to be the primary responsibility of SURE intern David Guenaga, who was tasked with planning and executing the campaign – prioritizing sites for survey, deploying GPS instruments in the field, and performing preliminary data quality control analysis and processing. In the 2015 campaign, over 40 sites were visited, of which 37 sites were measured. Data have been archived in the UNAVCO campaign GPS archive.
Intellectual Merit The research contributes to the SCEC objective of producing a Community Geodetic Model, through improving coverage and precision of campaign GPS measurements.
Broader Impacts The project gave an underrepresented minority student (intern David Guenaga) his first experience of scientific research and data collection. The data collected have been archived in the publicly-available UNAVCO campaign data archive for use by the research community in assessing strain accumulation on the major faults of the Inland Empire.
