Lunar data are available from printed or online tables. Tide tables forecast the time of the next high water. [6] [7] The difference between these two times is the lunitidal interval. This value can be used to calibrate tide clock and wristwatches to allow for simple but crude tidal predictions. Unfortunately, the lunitidal intervals vary day ...
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 ...
Tide flow information is most commonly seen on nautical charts, presented as a table of flow speeds and bearings at hourly intervals, with separate tables for spring and neap tides. The timing is relative to high water at some harbour where the tidal behaviour is similar in pattern, though it may be far away.
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.
Comox (English: / ˈ k oʊ m ɒ k s /) [4] is a town on the southern coast of the Comox Peninsula in the Strait of Georgia on the eastern coast of Vancouver Island, British Columbia. [1] Thousands of years ago, the warm dry summers, mild winters, fertile soil, and abundant sea life attracted First Nations , who called the area kw'umuxws ...
On nautical charts, the top of the chart is always true north, rather than magnetic north, towards which a compass points. Most charts include a compass rose depicting the variation between magnetic and true north. However, the use of the Mercator projection has drawbacks. This projection shows the lines of longitude as parallel.

On February 15, 2008, the regional district was abolished and replaced by two successor regional districts, Comox Valley and Strathcona. The district covered large portions of northern Vancouver Island and included part of the mainland north of the Sunshine Coast. As of the 2006 census, the Regional District had a population of 101,595.
