Nathaniel Bowditch
Nathaniel Bowditch (March 26, 1773 – March 16, 1838) was an early American mathematician remembered for his work on ocean navigation. He is often credited as the founder of modern maritime navigation; his book '' The New American Practical Navigator'', first published in 1802, is still carried on board every commissioned U.S. Naval vessel. In 2001, an elementary and middle school in Salem was named in his honor. Life and work Nathaniel Bowditch, the fourth of seven children, was born in Salem, Province of Massachusetts Bay, to Habakkuk Bowditch, a cooper who at one point was a sailor as well but stopped after his ship went aground in 1775, and Mary Ingersoll Bowditch. At the age of ten, he was made to leave school to work in his father's cooperage, before becoming indentured at twelve for nine years as a bookkeeping apprentice to a ship chandler. Here is where he first learned bookkeeping, an important step in his life. In 1786, age fourteen, Bowditch began to study alg ...

Notice To Mariners
A notice to mariners (NTM or NOTMAR,) advises mariners of important matters affecting navigational safety, including new hydrographic information, changes in channels and aids to navigation, and other important data. Over 60 countries which produce nautical charts also produce a notice to mariners. About one third of these are weekly, another third are bi-monthly or monthly, and the rest irregularly issued according to need. For example, the United Kingdom Hydrographic Office issues weekly updates. United States The U.S. ''Notice to Mariners'' is made available weekly by the National Geospatial-Intelligence Agency (NGA), prepared jointly with the National Ocean Service (NOS) and the U.S. Coast Guard. The information in the ''Notice to Mariners'' is formatted to simplify the correction of paper charts, ''List of Lights'', ''Light Lists'', ''United States Coast Pilots'', and other publications produced by NGA, NOS, and the U.S. Coast Guard.

Local Notice To Mariners
A Local Notice to Mariners is an authoritative instruction issued by a designated official, typically the harbormaster. United States In the United States, notices are issued by each U.S. Coast Guard District to disseminate important information affecting navigational safety within that District. This Notice reports changes and deficiencies in aids to navigation maintained by the Coast Guard. Other marine information such as new charts, channel depths, naval operations, and regattas is included. Since temporary information of short duration is not included in the weekly Notice to Mariners, the ''Local Notice to Mariners'' may be the only source of such information. Small craft using the Intracoastal Waterway and small harbors not normally used by oceangoing vessels need it to keep charts and publications up-to-date. Since correcting information for U.S. charts in the ''Notice to Mariners'' is obtained from the Coast Guard Local Notices, it is normal to expect a lag of 1 or 2 week ...

List Of Lights
A list of lights is a publication describing lighthouses and other aids to maritime navigation. Most such lists are published by national hydrographic offices. Some nations, including the United Kingdom and the United States, publish lists that cover the whole world in many volumes. Other nations publish lists that cover only their own coasts. Canada The Canadian Coast Guard publishes the ''List of Lights, Buoys and Fog Signals'' in four volumes which are updated periodically *Newfoundland and Labrador *Inland Waters *Atlantic Coast * Pacific Coast The books are available in paper from dealers. As well, HTML and PDF formats updated up to the latest version of the Monthly Notices to Mariners can be viewed online. The PDF format is also available for free download. Chile The Chilean official list of lighthouses is the ''Lista de Faros de la costa de Chile, Costa Oriental de Tierra del Fuego y Territorio Antártico'' published (as Nr. 3007) by the Hydrographic and Oceanograph ...

Buoy
A buoy () is a floating device that can have many purposes. It can be anchored (stationary) or allowed to drift with ocean currents. Types Navigational buoys * Race course marker buoys are used for buoy racing, the most prevalent form of yacht racing and power boat racing. They delimit the course and must be passed to a specified side. They are also used in underwater orienteering competitions. * Emergency wreck buoys provide a clear and unambiguous means of temporarily marking new wrecks, typically for the first 24–72 hours. They are coloured in an equal number of blue and yellow vertical stripes and fitted with an alternating blue and yellow flashing light. They were implemented following collisions in the Dover Strait in 2002 when vessels struck the new wreck of the . * Ice marking buoys mark holes in frozen lakes and rivers so snowmobiles do not drive over the holes. * Large Navigational Buoys (LNB, or Lanby buoys) are automatic buoys over 10 m high equipped with ...

United States Coast And Geodetic Survey
The United States Coast and Geodetic Survey (abbreviated USC&GS), known from 1807 to 1836 as the Survey of the Coast and from 1836 until 1878 as the United States Coast Survey, was the first scientific agency of the United States Government. It existed from 1807 to 1970, and throughout its history was responsible for mapping and charting the coast of the United States, and later the coasts of U.S. territories. In 1871, it gained the additional responsibility of surveying the interior of the United States and geodesy became a more important part of its work, leading to it being renamed the U.S. Coast and Geodetic Survey in 1878. Long the U.S. Government's only scientific agency, the Survey accumulated other scientific and technical responsibilities as well, including astronomy, cartography, meteorology, geology, geophysics, hydrography, navigation, oceanography, exploration, pilotage, tides, and topography. It also was responsible for the standardization of weights and measures th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Territory Of Alaska
The Territory of Alaska or Alaska Territory was an organized incorporated territory of the United States from August 24, 1912, until Alaska was granted statehood on January 3, 1959. The territory was previously Russian America, 1784–1867; the Department of Alaska, 1867–1884; and the District of Alaska, 1884–1912. Origin Passage of the 1899 Criminal Code which, among other things, included a tax on liquor, led to increased calls for Alaskan representation in Congress, and the debate finally ended on August 24, 1912, when the Alaska District became an organized, incorporated territory of the United States. The ''Second Organic Act'' of 1912 renamed the District the Territory of Alaska. By 1916, its population was about 58,000. James Wickersham, a Delegate to Congress, introduced Alaska's first statehood bill, but it failed for lack of interest from Alaskans. Even President Warren G. Harding's unprecedented visit in 1923 (just days before his death) could not create wides ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States West Coast
The West Coast of the United States, also known as the Pacific Coast, Pacific states, and the western seaboard, is the coastline along which the Western United States meets the North Pacific Ocean. The term typically refers to the contiguous U.S. states of California, Oregon, and Washington, but sometimes includes Alaska and Hawaii, especially by the United States Census Bureau as a U.S. geographic division. Definition There are conflicting definitions of which states comprise the West Coast of the United States, but the West Coast always includes California, Oregon, and Washington as part of that definition. Under most circumstances, however, the term encompasses the three contiguous states and Alaska, as they are all located in North America. For census purposes, Hawaii is part of the West Coast, along with the other four states. ''Encyclopædia Britannica'' refers to the North American region as part of the Pacific Coast, including Alaska and British Columbia. Although the enc ...
