Field Activity Collection System (FACS) Logs

FACS logs are standardized forms used by the USGS Coastal and Marine Geology Program. For more information see http://walrus.wr.usgs.gov/infobank/programs/html/main/facs.html. Click on the links below to access PDF files containing the FACS crew, equipment, operation, and overview logs. Digital FACS logs were generated after the cruise using the handwritten logbooks and personal accounts of the crew members. Handwritten FACS logs were completed in the field by D. Wiese. All logs can be found within the LOGBOOKS folder.

NOTE: The original trace files for some lines were divided into two trace files each (for example, 05c01 became 05c01_a and 05c01_b) because the original total number of traces exceeded the maximum allowed by the processing software.
