CREWS Standard (CREWS-STD) buoys are equipped to measure sea surface water temperature and conductivity (Sea-Bird Model SBE37-SM, Sea-Bird Electronics, Inc., www.seabird.com) at 1 m (nominal) below the water line and air temperature (R.M Young Model 41342); barometric pressure (Heise DXD and wind vectors (Vaisala WAS425A) at 2 m (nominal) above the water line. A compass (KVH C100 SE-25) is used in the calculation of wind direction and a GPS system provides geolocation. CREWS-STD buoys telemeter hourly data in near-real-time (NRT). Data telemetry serves to alert researchers to the potential of imminent or ongoing coral reef bleaching or other natural events (hurricanes, storm damage, cooling, etc.) so that additional field observations and data collection efforts can be initiated, if warranted. NRT data is available at https://www.fisheries.noaa.gov/pacific-islands/ecosystems/coral-reefs-pacific and is updated on a daily basis. When a buoy is recovered, a higher resolution (typically a 1800 second sampling interval) dataset is uploaded from the buoy's Environmental Data Logger (EDL). Please contact CRED with any questions.
