Lake Pontchartrain ( ; ) is an estuary located in southeastern Louisiana in the United States. It covers an area of with an average depth of . Some shipping channels are kept deeper through dredging. It is roughly oval in shape, about from west to east and from south to north. In descending order of area, the estuary is located in parts of six Louisiana parishes: St. Tammany, Orleans, Jefferson, St. John the Baptist, St. Charles, and Tangipahoa. The water boundaries were defined in 1979 (see list of parishes in Louisiana). The estuary is crossed by the Lake Pontchartrain Causeway, the longest continuous bridge over water in the world. A power line also crosses the estuary. Its towers stand on caissons in Lake Pontchartrain, and its length can be used to visually demonstrate the curvature of the Earth. Toponymy Lake Pontchartrain was named for Louis Phélypeaux, Comte-de-Pontchartrain. He was the French Minister of the Marine, Chancellor, and Controller-General o ...

Both are in the New Orleans metropolitan area. The Lake Pontchartrain Causeway holds the Guinness World Records, Guinness World Record for longest ''continuous'' span over water in the world. It previously was listed as List of longest bridges in the world, longest bridge over water in the world; in 2011, in response to the opening of the Qingdao Jiaozhou Bay Bridge in China, ''Guinness World Records'' created two categories for bridges over water: Lake Pontchartrain Causeway then became the longest bridge over water (continuous), while the Jiaozhou Bay Bridge became the longest bridge over water (aggregate). The bridges are supporte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sentinel-2
Sentinel-2 is an Earth observation mission from the Copernicus Programme that acquires optical imagery at high spatial resolution (10 m to 60 m) over land and coastal waters. The mission's Sentinel-2A and Sentinel-2B satellites were joined in orbit in 2024 by a third, Sentinel-2C, and in the future by Sentinel-2D, eventually replacing the A and B satellites, respectively. The mission supports services and applications such as agricultural monitoring, emergencies management, land cover classification, and water quality. Sentinel-2 has been developed and is being operated by the European Space Agency. The satellites were manufactured by a consortium led by Airbus Defence and Space in Friedrichshafen, Germany. Overview The Sentinel-2 mission includes: * Multispectral image, Multi-spectral data with 13 bands in the Visible spectrum, visible, Infrared#Regions within the infrared, near infrared, and Infrared#Regions within the infrared, short wave infrared part of the Electromagnetic ...

Rigolets
Rigolets is a deepwater strait in Louisiana. "Rigolets" comes from the word ''rigole'', French for 'trench' or 'gutter'. The name is now locally pronounced "RIG-uh-leez". The strait begins at and follows a generally eastward course to Lake Borgne, a lagoon in the Gulf of Mexico, and finally to the Gulf of Mexico, where it ends at . Along with nearby Chef Menteur Pass, the Rigolets connects Lake Pontchartrain and Lake St. Catherine in Louisiana to Lake Borgne, and then to the Gulf of Mexico. It forms the boundary between New Orleans (Orleans Parish) and St. Tammany Parish. Tidal pass As a deepwater tidal pass, the Rigolets helps supply salt water from the Gulf to Lake Pontchartrain. Tidal scouring has produced a deep pit in the lake at the western mouth of the strait. Since the Rigolets is a channel through which Gulf storm surges can approach the New Orleans area, there have been proposals to construct floodgates to try to protect the city, especially since the destructi ...
