The datum from which the predicted heights of tides are reckoned in the tide tables is the same as that used for the charts of the locality. The depression of the datum below mean sea level for Hampton Roads, Virginia is __________.

Correct Answer: Option A — 1.2 feet

Tide tables provide heights relative to a specific chart datum, typically Mean Lower Low Water (MLLW). For Hampton Roads, the difference between the chart datum and Mean Sea Level is established by NOAA tidal benchmarks as 1.2 feet, ensuring consistency between charted depths and predicted tidal heights.
