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 ...
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.
Featuring the highest tides in the world, the Bay of Fundy exposes ocean floor at low tide which is covered by up to 16 m (52 ft) of salt water at high tide. [22] The park forms the core portion of the UNESCO Fundy Biosphere Reserve. Georgian Bay Islands † Ontario
Sheet Harbour became a prosperous hub for the lumber industry. A sawmill was built around 1863 at the tide head of East River, though its operating company dissolved a few years later due to financial issues. The first sulphide pulp mill in Canada was built in 1885 at East River. [6] The mill closed in 1891 due to the cost of importing sulphide.
Rising from its source at Lac Brûlé, the Rivière du Nord comes from the north-northwest rather than from the north and flows east of Sainte-Agathe-des-Monts and waters several settlements, including Val-David, Sainte-Adèle, Prévost (formerly Shawbridge) and Saint-Jérôme.
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).
