General Information

Location: 60.794 North -148.285 West
Buoy Type: 6-meter NOMAD buoy
Buoy Hull: 6N35
Payload: ARES 4.4 payload
Owned by: NDBC
Windspeed: Measured by obtained from anemometer
Sea Surface: Measured by Intake
Note: Station 46081 stopped transmitting 12/04/11. This buoy will be restored to service when it can be worked into the schedule.  When the service date is known, it will be posted in the maintenance report. Funding to support water measurements of the velocity profile, temperature, and salinity is provided by the Prince William Sound Science Center. NDBC ADCPs are now quality controlled using automated methods. Historical and forty-five day files beginning 1 June 2010 are available in a new format that contains more QC information.  The forty-five day files in the old format will be resident until approximately 31 July 2010.
