The dates of spring tides and neap tides, approximately seven days apart, can be determined by the heights of the tides on the classic tide tables: a small range indicates neaps and large indicates springs. This cycle of tides is linked to the phases of the moon, with the highest tides (spring tides) occurring near full moon and new moon.
Common chart datums are lowest astronomical tide (LAT) [1] and mean lower low water (MLLW). In non-tidal areas, e.g. the Baltic Sea , mean sea level (MSL) is used. [ 2 ] A chart datum is a type of vertical datum and must not be confused with the horizontal datum for the chart.

But in 1884, a 104-foot high iron lighthouse rose above the waters on the Gulf Coast and 90 years later, in 1974, the lighthouse and its quarters made it into the National Register of Historic Places.
Tidal range is the difference in height between high tide and low tide. Tides are the rise and fall of sea levels caused by gravitational forces exerted by the Moon and Sun, by Earth's rotation and by centrifugal force caused by Earth's progression around the Earth-Moon barycenter. Tidal range depends on time and location.
The historic Sanibel Island Lighthouse has weathered many a hurricane, but the fortitude of the skeleton lighthouse was put to the test once more when Hurricane Ian roared ashore. The high-end ...
