The Regional Cabled Array (RCA) operation and management cruise, funded by the National Science Foundation as part of the Ocean Observatories Initiative, will take place July 31- September 1, 2020 onboard the R/V Thomas G. Thompson, operated by the University of Washington. All of the Cabled Array instruments that are being replaced during the cruise will be deactivated on 01 August to avoid calibration mismatches as the in-water instruments are unplugged and new ones plugged in. The newly deployed instruments will be turned back on as soon as possible after each leg of the cruise, with 01 September being the absolute latest that they come back online. Once they have been reactivated, the data will backfill with the appropriate serial numbers and calibration info to repopulate the gap.
