““Not to Interfere” CONSIDERATIONSNot to Interfere” CONSIDERATIONS
Deployed/recovered with buoy on station Entire package removed prior to ATON
servicing All similar metals
and coloration Minimal alteration
of buoy profile
and characteristics

No obvious bias in ATONMean difference ~ 3cm/s
Speeds compare very well, within anticipated error of individual instruments

GPS COMPASS CALIBRATIONGPS COMPASS CALIBRATION
GOALSRotate GPS compass and Nortek to determine the effectiveness of the Nortek compass calibration
algorithm
Evaluate potential for GPS compass calibration of the Nortek
Thales GPS Compass10 Hz compass sampling rate,
1 sec average
Nortek1 sec compass sampling rate

Comparison of current direction to a bottom-mounted ADCPimproves with increasing speed
much of the difference is real spatial variability

BATTERY LIFE
Easily achieve 180 day deployment with 0.1 watt Radio
1 watt radio required further power saving modifications,297 days and counting.

Quick Response Estuarine Buoy (QREB)
Support for hazmat response
Easily deployed from small vessel
Short duration deployment (90 days)
Survive moderate gale
Report current profile and met data at 6 minute intervals
