Marine science in the context of "Marine geology"

A submarine (often shortened to sub) is a watercraft capable of independent operation underwater. (It differs from a submersible, which has more limited underwater capability.) The term "submarine" is also sometimes used historically or informally to refer to remotely operated vehicles and robots, or to medium-sized or smaller vessels (such as the midget submarine and the wet sub). Submarines are referred to as boats rather than ships regardless of their size.

Although experimental submarines had been built earlier, submarine design took off during the 19th century, and submarines were adopted by several navies. They were first used widely during World War I (1914–1918), and are now used in many navies, large and small. Their military uses include: attacking enemy surface ships (merchant and military) or other submarines; aircraft carrier protection; blockade running; nuclear deterrence; stealth operations in denied areas when gathering intelligence and doing reconnaissance; denying or influencing enemy movements; conventional land attacks (for example, launching a cruise missile); and covert insertion of frogmen or special forces. Their civilian uses include: marine science; salvage; exploration; and facility inspection and maintenance. Submarines can be modified for specialized functions such as search-and-rescue missions and undersea cable repair. They are also used in the tourism industry and in undersea archaeology. Modern deep-diving submarines derive from the bathyscaphe, which evolved from the diving bell.

The University of Cádiz (in Spanish: Universidad de Cádiz), commonly referred to as UCA, is a public university located in the province of Cádiz, Andalusia, Spain, noted for its medicine and marine sciences curricula. It was founded in 1979, and has the Latin motto Non Plus Ultra ("No Further Beyond"). Its headquarters are located in Cádiz, where the Rectorate is. During the 2007/2008 academic year, there were 17,280 students, 1,698 lecturers, and 680 administration and services workers associated with the university.

Woods Hole is a census-designated place in the town of Falmouth in Barnstable County, Massachusetts, United States. It lies at the extreme southwestern corner of Cape Cod, near Martha's Vineyard and the Elizabeth Islands. The population was 781 at the 2010 census.

It is the site of several marine science institutions, including Woods Hole Oceanographic Institution, the Marine Biological Laboratory, the Woodwell Climate Research Center, NOAA's Northeast Fisheries Science Center (which started the Woods Hole scientific community in 1871), the Woods Hole Science Aquarium, a USGS coastal and marine geology center, and the home campus of the Sea Education Association.
