During winter months, cold and ice may
result in inaccurate real-time tide elevation data. Adjustments or
deletions of this data can only be done after detailed

The water temperature data for this station
are temporary and will only be displayed for 120 days. Although the
instrumentation is calibrated at least once/year, the temporary
classification means that documented routine inspections and other
quality assurance measures are not performed that would make the data
acceptable for archival, retrieval, or future use in general scientific
or interpretive studies.
