On 11 October 2021, the National Oceanic and Atmospheric Administration (NOAA)requested that OOI’s Coastal Endurance Array buoys provide hourly meteorological data to the National Data Buoy Center (NDBC) because a nearby NDBC buoy (46029, Columbia River bar) had gone offline. OOI buoy data are typically telemetered every two hours due to sampling schedule and bandwidth constraints (the actual sampling rate is higher).
Endurance Array team members examined sampling and telemetry schedules for the Endurance offshore coastal surface moorings to see if they could accommodate NOAA’s request. The team concluded that meteorological data from the moorings could be updated hourly while still meeting OOI sampling requirements.
“To help ensure continuity of data to the NDBC, we plan to distribute hourly meteorological data from the Endurance Array Oregon and Washington offshore sites for the duration of the outage at NBDC 46029,” said Edward Dever, lead of the Coastal Endurance Team. “We’re pleased to respond to NOAA’s request and hope these data prove useful to operational weather forecasts and marine safety.” The Oregon and Washington offshore sites have NDBC buoys designations of 46098 and 46100, respectively.
The Endurance Array team will continue to review the performance of the buoys and ensure the updated telemetry schedule does not impact OOI sampling. If data users do experience any impacts from this change in sampling frequency, please contact Jon Fram at Jonathan.Fram@oregonstate.edu.
