Tide tables, sometimes called tide charts, are used for tidal prediction and show the daily times and levels of high and low tides, usually for a particular location. [1] Tide heights at intermediate times (between high and low water) can be approximated by using the rule of twelfths or more accurately calculated by using a published tidal ...
A chart datum is the water level surface serving as origin of depths displayed on a nautical chart and for reporting and predicting tide heights. A chart datum is generally derived from some tidal phase, in which case it is also known as a tidal datum. [1] Common chart datums are lowest astronomical tide (LAT) [1] and mean lower low water (MLLW).
The first tide predicting machine (TPM) was built in 1872 by the Légé Engineering Company. [11] A model of it was exhibited at the British Association meeting in 1873 [12] (for computing 8 tidal components), followed in 1875-76 by a machine on a slightly larger scale (for computing 10 tidal components), was designed by Sir William Thomson (who later became Lord Kelvin).

The king tide is the highest predicted high tide of the year at a coastal location. It is above the highest water level reached at high tide on an average day. When is a king tide?
The Mickler's did mail-order business as Mickler's Antiquarian Books for almost 40 years. They were skilled in obtaining out-of-print publications about Florida and collected more than 40,000 books and other historical pieces of paper memorabilia (known as ephemera, [4] in the trade). [2] Thomas Mickler was a native Floridian. He died in 1997.
Officially produced tide tables should be used in preference whenever possible. The rule assumes that all tides behave in a regular manner, this is not true of some geographical locations, such as Poole Harbour [ 5 ] or the Solent [ 6 ] where there are "double" high waters or Weymouth Bay [ 5 ] where there is a double low water.
The woman accused of stabbing a postal worker to death over a spot in line at a Harlem deli has a long history of knife violence — and once threatened “to cut” one of her previous victims.
The mature, sparsely vegetated, scrubby dunes offer the best burrowing environment, as well as providing the mice with ample food sources. These dunes tend to occur between the high-tide line and the more densely vegetated dunes farther inland. Though sometimes found in the inland dunes, very little foraging takes place there.
