Icebreaker
An icebreaker is a special-purpose ship or boat designed to move and navigate through ice-covered waters, and provide safe waterways for other boats and ships. Although the term usually refers to ice-breaking ships, it may also refer to smaller vessels, such as the icebreaking boats that were once used on the canals of the United Kingdom. For a ship to be considered an icebreaker, it requires three traits most normal ships lack: a strengthened hull, an ice-clearing shape, and the power to push through sea ice. Icebreakers clear paths by pushing straight into frozen-over water or pack ice. The bending strength of sea ice is low enough that the ice breaks usually without noticeable change in the vessel's trim. In cases of very thick ice, an icebreaker can drive its bow onto the ice to break it under the weight of the ship. A buildup of broken ice in front of a ship can slow it down much more than the breaking of the ice itself, so icebreakers have a specially designed hull ...

Ice Navigation
Ice navigation is a specialist area of navigation involving the use of maritime skills to determine and monitor the position of ships in cold waters, where ice is a hazard to the safety of navigation. The presence of sea ice requires a ship to exercise caution, for example by avoiding icebergs, slowly sailing through a lead, or by working with an icebreaker to follow a course through the ice to a destination. Additionally ships must also deal with the extreme cold of the climate in regions such as the poles; this involves removal of ice accumulation from the ship, as well as protecting the crew from the elements while working on the deck. Ships and their crews operating in ice will follow established rules of seamanship, as well as complying with national and international regulations such as the Polar Code. Ice strengthened vessels are typically used for navigation in ice regions, where additional hull strengthening and other design elements ensure operation in areas of high ...

Sea Ice
Sea ice arises as seawater freezes. Because ice is less density, dense than water, it floats on the ocean's surface (as does fresh water ice). Sea ice covers about 7% of the Earth's surface and about 12% of the world's oceans. Much of the world's sea ice is enclosed within the polar ice packs in the Earth's polar regions: the Arctic ice pack of the Arctic Ocean and the Antarctic ice pack of the Southern Ocean. Polar packs undergo a significant yearly cycling in surface extent, a natural process upon which depends the Arctic ecology, including the Arctic sea ice ecology and history, ocean's ecosystems. Due to the action of winds, currents and temperature fluctuations, sea ice is very dynamic, leading to a wide variety of ice types and features. Sea ice may be contrasted with icebergs, which are chunks of ice shelf, ice shelves or glaciers that Ice calving, calve into the ocean. Depending on location, sea ice expanses may also incorporate icebergs. General features and dynamics ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
120106-G-IA651-272 (6668116881)
1 (one, unit, unity) is a number, Numeral (linguistics), numeral, and glyph. It is the first and smallest Positive number, positive integer of the infinite sequence of natural numbers. This fundamental property has led to its unique uses in other fields, ranging from science to sports, where it commonly denotes the first, leading, or top thing in a group. 1 is the unit (measurement), unit of counting or measurement, a determiner for singular nouns, and a gender-neutral pronoun. Historically, the representation of 1 evolved from ancient Sumerian and Babylonian symbols to the modern Arabic numeral. In mathematics, 1 is the multiplicative identity, meaning that any number multiplied by 1 equals the same number. 1 is by convention not considered a prime number. In Digital electronics, digital technology, 1 represents the "on" state in binary code, the foundation of computing. Philosophically, 1 symbolizes the ultimate reality or source of existence in various traditions. In math ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Paddle
A paddle is a handheld tool with an elongated handle and a flat, widened end (the ''blade'') used as a lever to apply force onto the bladed end. It most commonly describes a completely handheld tool used to propel a human-powered watercraft by pushing water in a direction opposite to the direction of travel (i.e. paddling). A paddle is different from an oar (which can be similar in shape and perform the same function via rowing) – an oar is attached to the watercraft via a fulcrum. The term "paddle" can also be used to describe objects of similar shapes or functions: *A rotating set of paddle boards known as a paddle wheel is used to propel a steamboat or paddle steamer. *In a number of racquet sports (e.g. ping-pong and paddle ball), a "paddle" or "bat" is a short, solid racket used to strike a ball. *A mixing paddle is a device used to stir or mix separate ingredients within a mixture. *A spanking paddle is used in corporal punishment, typically to forcefully hit someone ...

Paddler
Canoeing is an activity which involves paddling a canoe with a single-bladed paddle. In some parts of Europe, canoeing refers to both canoeing and kayaking, with a canoe being called an 'open canoe' or Canadian. A few of the recreational forms of canoeing are canoe camping and canoe racing. Other forms include a wide range of canoeing on lakes, rivers, oceans, ponds and streams. History of organized recreational canoeing Canoeing is an ancient mode of transportation. Modern recreational canoeing was established in the late 19th century. Among early promoters of canoeing as a sport was Carl Smith, who introduced canoeing to Sweden in the 1880s. In 1924, canoeing associations from Austria, Germany, Denmark, and Sweden founded the ''Internationalen Representation for Kanusport'', the forerunner of the International Canoe Federation (ICF). Canoeing became part of the Olympic Games in the 1936 Summer Olympics. which featured canoe sprint using a sprint canoe. Others compet ...

Kayaks
] A kayak is a small, narrow human-powered watercraft typically propelled by means of a long, double-bladed paddle. The word ''kayak'' originates from the Inuktitut word '' qajaq'' (). In British English, the kayak is also considered to be a kind of canoe. There are countless different types of kayaks due to the craft being easily adaptable for different environments and purposes. The traditional kayak has an enclosed deck and one or more cockpits, each seating one occupant or kayaker, differentiating the craft from an open-deck canoe. The cockpit is sometimes covered by a spray deck that prevents unwanted entry of water from waves or splashes. Even within these confines, kayaks vary vastly in respect to materials, length, and width, with some kayaks such as the sprint kayak designed to be fast and light, and others such as the whitewater kayak designed to be sturdy and maneuverable. Some modern paddlecrafts, which still claim the title "kayak", remove integral parts of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eskimo
''Eskimo'' () is a controversial Endonym and exonym, exonym that refers to two closely related Indigenous peoples: Inuit (including the Alaska Native Iñupiat, the Canadian Inuit, and the Greenlandic Inuit) and the Yupik peoples, Yupik (or Siberian Yupik, Yuit) of eastern Siberia and Alaska. A related third group, Aleuts, who inhabit the Aleutian Islands, are generally excluded from the definition of ''Eskimo''. The three groups share a relatively recent common ancestor, and speak related languages belonging to the family of Eskaleut languages. These circumpolar peoples have traditionally inhabited the Arctic and subarctic regions from eastern Siberia (Russia) to Alaska (United States), Northern Canada, Nunavik, Nunatsiavut, and Greenland. Some Inuit, Yupik, Aleut, and other individuals consider the term ''Eskimo'', which is of a disputed etymology, to be pejorative or even offensive. ''Eskimo'' continues to be used within a historical, linguistic, archaeological, and cultural ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Waterline
The waterline is the line where the hull of a ship meets the surface of the water. A waterline can also refer to any line on a ship's hull that is parallel to the water's surface when the ship is afloat in a level trimmed position. Hence, waterlines are a class of "ships lines" used to denote the shape of a hull in naval architecture lines plans. The load line (also known as Plimsoll line) is the waterline which indicates the legal limit to which a ship may be loaded for specific water types and temperatures in order to safely maintain buoyancy. For vessels with displacement hulls, the hull speed is defined by, among other things, the waterline length. In a sailing boat, the waterline length can change significantly as the boat heels, and can dynamically affect the speed of the boat. Aircraft In the aircraft design the term ''waterline'' designates a horizontal reference line used in alignment checks. The base line of the aircraft is designated as waterline 0 (zero). ...
