The Iris-class buoy tenders were constructed after the Mesquite-class buoy tenders. Hornbeam cost $864,296 to construct and had an overall length of 180 feet (55 m). She had a beam of 37 feet (11 m) and a draft of up to 12 feet (3.7 m) at the time of construction, although this was increased to 14 feet 7 inches (4.45 m) in 1966.
The NOMAD hull was developed from the "Roberts buoy," which was a 6.67-foot-long (2.03 m), 400-pound (181 kg) boat-shaped buoy developed in the early 1940s by the United States Coast and Geodetic Survey to measure strong tidal currents. The buoy's performance was satisfactory, but its limited size significantly restricted its use in other areas ...
A cardinal mark is a sea mark (a buoy or other floating or fixed structure) commonly used in maritime pilotage to indicate the position of a hazard and the direction of safe water. Cardinal marks indicate the direction of safety as a cardinal ( compass ) direction ( north , east , south or west ) relative to the mark.
This advanced capability is useful in bringing buoys aboard that can weigh more than 16,000 lbs. [7] Electrical power aboard is provided by three Caterpillar 3406 DITA generators which produce 285 Kw each. [7] She also has a 210 Kw emergency generator, which is a Caterpillar 3406 DIT. [9] The buoy deck has 1,335 square feet (124.0 m 2) of ...
A self-locating datum marker buoy (SLDMB) is a drifting surface buoy designed to measure surface ocean currents. The design is based on those of the Coastal Ocean Dynamics Experiment (CODE) and Davis-style oceanographic surface drifters – National Science Foundation (NSF) funded experiments exploring ocean surface currents.

In 1970, NOAA was formed and the NOAA Data Buoy Office (NDBO) was created within the National Ocean Service (NOS) and located in Mississippi. In 1982, the NDBO was renamed NDBC and was placed under NOAA's NWS. The first buoys deployed by NDBC were the large 12-m discus hulls constructed of steel.
Each DART station consists of a surface buoy and a seafloor bottom pressure recording (BPR) package that detects water pressure changes caused by tsunamis.The surface buoy receives transmitted information from the BPR via an acoustic link and then transmits data to a satellite, which retransmits the data to ground stations for immediate dissemination to NOAA's Tsunami Warning Centers, NOAA's ...
