Large Lakes Observatory
The Large Lakes Observatory (or LLO) is a research institute located in Duluth, Minnesota, USA which studies the major lakes of the world. The researchers focus on a variety of sciences including aquatic chemistry, geochemistry and paleoclimatology. Its stated purpose dedicates the LLO to "performing innovative, cross-disciplinary research, education, and outreach that advance scientific understanding of Earth’s large lakes for the benefit of society and the sustainability of freshwaters." The parent institution of LLO is the University of Minnesota Duluth. History The Large Lakes Observatory was founded in 1994, after a 1988 scientific and policy conference resulted in the formation of the "Institute for Lake Superior Research" which developed into the LLO. It moved into its present location in the Research Laboratory Building in Duluth, MN after a fire in the former Old Main campus building (now the site of Old Main Park) left the Model School building untouched.

Length Overall
__NOTOC__ Length overall (LOA, o/a, o.a. or oa) is the maximum length of a vessel's hull measured parallel to the waterline. This length is important while docking the ship. It is the most commonly used way of expressing the size of a ship, and is also used for calculating the cost of a marina berth (for example, £2.50 per metre LOA). LOA is usually measured on the hull alone. For sailing ships, this may ''exclude'' the bowsprit and other fittings added to the hull. This is how some racing boats and tall ships use the term LOA. However, other sources may include bowsprits in LOA. Confusingly, LOA has different meanings. "Sparred length", "Total length including bowsprit", "Mooring length" and "LOA including bowsprit" are other expressions that might indicate the full length of a sailing ship. LOD Often used to distinguish between the length of a vessel including projections (e.g. bow sprits, etc.) from the length of the hull itself, the Length on Deck or LOD is often repor ...

University-National Oceanographic Laboratory System
The University-National Oceanographic Laboratory System (UNOLS) is a group of academic institutions and National Laboratories organized in the United States to coordinate research vessel use for federally funded ocean research. Authority The UNOLS system grew from the recognition during the rapid expansion of oceanographic activity that there was no organized means of coordinating ship time requests of researchers, particularly those from institutions not operating vessels and that more expensive ships were not the answer. Federal research sponsors were concerned about more effective use of those expensive assets. Even though a more formal National Oceanographic Laboratory system was not established the less formal and less federally controlled cooperative system of the University-National Oceanographic Laboratory System was established. The form this took lay between federal control of the fleet and uncoordinated use of the often federally owned research vessels at the institutions ...

Qinghai Lake
Qinghai Lake or Ch'inghai Lake, also known by other names, is the largest lake in China. Located in an endorheic basin in Qinghai Province, to which it gave its name, Qinghai Lake is classified as an alkaline salt lake. The lake has fluctuated in size, shrinking over much of the 20th century but increasing since 2004. It had a surface area of , an average depth of , and a maximum depth of in 2008. Names Qinghai is the romanized Standard Chinese pinyin pronunciation of the name Although modern Chinese distinguishes between the colors blue and green, this distinction did not exist in classical Chinese. The color (''qīng'') was a "single" color inclusive of both blue and green as separate shades. (English for ''qīng'' is cyan or turquoise, also linguists have coined the portmanteau "grue" to discuss its existence in Chinese and other languages.) The name is thus variously translated as "Blue Sea", "Green Sea", "Blue-Green Sea", "Blue/Green Sea", etc. For a time after ...

Lake Nicaragua
Lake Nicaragua or Cocibolca or Granada ( es, Lago de Nicaragua, , or ) is a freshwater lake in Nicaragua. Of tectonic origin and with an area of , it is the largest lake in Central America, the 19th largest lake in the world (by area) and the tenth largest in the Americas, slightly smaller than Lake Titicaca. With an elevation of above sea level, the lake reaches a depth of . It is intermittently joined by the Tipitapa River to Lake Managua. The lake drains to the Caribbean Sea via the San Juan River, historically making the lakeside city of Granada an Atlantic port, although Granada (as well as the entire lake) is closer to the Pacific Ocean geographically. The Pacific is near enough to be seen from the mountains of Ometepe (an island in the lake). The lake has a history of Caribbean pirates who assaulted Granada on three occasions. Before construction of the Panama Canal, a stagecoach line owned by Cornelius Vanderbilt's Accessory Transit Company connected the lake with ...
