Datums for 8764314, Eugene Island, North of , Gulf of Mexico LA

NOTICE: Data for determining a datum at this station was collected using non-standard methodologies and may not meet CO-OPS highest level of accuracy of 2 cm (0.8 in). The estimated error associated with the average six-minute water level observations relative to datum is expected to be within +/- 8 cm (3 in) at 95% confidence. Recognizing that these data can be used for certain applications CO-OPS is making these data available to its users with restraint. Users are cautioned to consider the accuracy of these data before using them for critical navigational or coastal engineering purposes.
