Datums for 9465265, KULUKAK POINT AK

Data Quality Data from this station was collected using methodology that does not meet CO-OPS highest level of accuracy (no more than 10 cm, 95% Confidence Interval (CI) referenced to a tidal datum). Recognizing that lower quality data can be used for certain applications CO-OPS is making this data available to its users with restraint. The average six-minute water level observations derived from this system have an accuracy ranging from 10.0 - 30.0 cm, 95% CI on datum. Users are cautioned to consider the accuracy of these data before using them for critical navigational or coastal engineering purposes.
NOTICE: All data values are relative to the MLLW.
