Marker buoys, used in naval warfare (particularly anti-submarine warfare) emit light and/or smoke using pyrotechnic devices to create the flare and smoke. Commonly 3 ...
Weather Buoy / Data Buoy / Oceanographic Buoy operated by the Marine Data Service. The first known proposal for surface weather observations at sea occurred in connection with aviation in August 1927, when Grover Loening stated that "weather stations along the ocean coupled with the development of the seaplane to have an equally long range, would result in regular ocean flights within ten years."
Twelve buoys were originally deployed in 1997. Two of these buoys were decommissioned in 1999 because of vandalism by fishing craft. Three extensions of the original network have been added. Three buoys were deployed off the coast of Brazil in 2005 and four more in 2006/2007 to extend coverage to the north and the north-east.

Sonobuoy being loaded onto a USN P-3C Orion aircraft Hand deployment of a sonobuoy in the Arctic Ocean from the aft deck of the R/V Sikuliaq. A sonobuoy (a portmanteau of sonar and buoy) is a small expendable sonar buoy dropped from aircraft or ships for anti-submarine warfare or underwater acoustic research.
The buoys were of square or hexagonal construction and had a floor space of about 4m² (43 square feet) with an 2.4m (8 feet) tall cabin rising above the float. On the upper deck of this cabin, there was an oval turret 1.8m (6 feet) high with a signal mast carrying a wireless antenna.
The surface buoy sends the data by radio to satellites such as the Iridium system. From the satellites, the data travels by radio to the ground, then to the system office by conventional telecommunications. [8] The surface buoy has a two and a half meter diameter fiberglass disk covered with foam and has a gross displacement of 4000 kg. [9]
They are also known as fairway buoys and clear water buoys. They are recognisable by their red-and-white vertical stripes and commonly bear a top sign in shape of a red ball. They either flash Morse code "A" (di-dah), or one long flash, occulting (more light than dark) or isophase (equal light and dark) every 10 seconds (L Fl 10s).
