The CHS is administratively part of Fisheries and Oceans Canada's Oceans and Ecosystems Science Sector. According to mandated obligations of the Oceans Act and the Canada Shipping Act, the CHS is led by the Hydrographer General of Canada who is responsible for gathering, managing, transforming and disseminating bathymetric, hydrographic and nautical data and information into paper and ...
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.
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).

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
Tide range is the vertical distance between the highest high tide and lowest low tide. The size of the lunar tide compared to the solar tide (which comes once every 12 hours) is generally about 2 to 1, but the actual proportion along any particular shore depends on the location, orientation, and shape of the local bay or estuary.
Canada has a vast geography that occupies much of the continent of North America, sharing a land border with the contiguous United States to the south and the U.S. state of Alaska to the northwest. Canada stretches from the Atlantic Ocean in the east to the Pacific Ocean in the west; to the north lies the Arctic Ocean. [1]
