Jeffrey J. McGuire 20221109 spreadsheet https://doi.org/10.5066/P9XLMDOL These data are from a 3-month long deployment of nodal seismometers that ran from May 18th, 2022 until September 1st, 2022 as part of a Distributed Acoustic Sensing (DAS) experiment above the Gorda plate (McGuire, et al., 2022). The sensors were deployed at 44 locations along Old Arcata Rd between Arcata and Eureka California (Figure 1); these locations track the approximate location of the fiber optic cable used as part of the DAS experiment. The instruments have a battery recording life of approximately one month and were swapped out in the same locations in Mid-June, and Mid-July. Thus, there are 132 instruments that were deployed at 44 distinct locations. This record covers the data from the first month (2022-05-18 through 2022-06-16) of the deployment The data record numerous local earthquakes. 20220515 20220616 observed Complete None planned Arcata California -126.2109 -123.4863 41.1125 39.5040 ISO 19115 Topic Category biota None earthquake USGS Thesaurus earthquakes USGS Metadata Identifier USGS:6362da3cd34ebe442506b93a None Arcata California None.
