Admiralty Tide Tables. North Atlantic Ocean and Arctic Regions. NP202. Volume 2. 2025

Издание на английском языке
Vol. 2: General arrangement
Part I of these tables gives daily predictions of the times and heights of high and low waters at a selected number of Standard Ports. The list of Standard Ports is given at the front of the book.
Part II gives data for prediction at a large number of Secondary Ports; this is in the form of time and height differences, referred to one of the Standard Ports in Part I.
Part III lists the harmonic constants which can be used for prediction by the Simplified Harmonic Method of Tidal Prediction, (see also page xxix).
Part IIIa lists harmonic constants of the tidal streams which can be used for prediction by the Simplified Harmonic Method of Tidal Prediction, (see also page xxix).
This volume also contains an introduction dealing with, in particular, the effect of meteorological conditions on tidal heights; there are also a number of special tables and other information for use with the tide tables.
