NOAA Center For Tsunami Research
The NOAA Center for Tsunami Research (NCTR), located at the Pacific Marine Environmental Laboratory (PMEL) in Seattle, Washington (state), Washington, performs research in support of tsunami forecast models to increase the speed and accuracy of operational forecasts and warnings, tsunami inundation models to predict tsunami impacts on coastal communities, and tsunami measurement/detection technology for optimally designed networks of tsunami buoys. Tsunami measurements and forecast modeling PMEL/NCTR developed and holds the patent on the Deep-ocean Assessment and Reporting of Tsunamis DART® tsunami detection buoy that forms the backbone of the global tsunami detection network. Operational support for the DART® buoys has been transitioned to NDBC. The NCTR's SIFT tsunami forecasting system is described in the NCTYouTube video about the 2010 Chile tsunami event and in more detail in the NCTR Power Point presentation Developing tsunami flooding forecast software'. The SIFT system ...

Tsunami
A tsunami ( ; from ja, 津波, lit=harbour wave, ) is a series of waves in a water body caused by the displacement of a large volume of water, generally in an ocean or a large lake. Earthquakes, volcanic eruptions and other underwater explosions (including detonations, landslides, glacier calvings, meteorite impacts and other disturbances) above or below water all have the potential to generate a tsunami. Unlike normal ocean waves, which are generated by wind, or tides, which are in turn generated by the gravitational pull of the Moon and the Sun, a tsunami is generated by the displacement of water from a large event. Tsunami waves do not resemble normal undersea currents or sea waves because their wavelength is far longer. Rather than appearing as a breaking wave, a tsunami may instead initially resemble a rapidly rising tide. For this reason, it is often referred to as a tidal wave, although this usage is not favoured by the scientific community because it might give ...

Pacific Tsunami Warning Center
The Pacific Tsunami Warning Center (PTWC) is one of two tsunami warning centers that are operated by NOAA in the United States. Headquartered on Ford Island, HI, the PTWC is part of an international tsunami warning system (TWS) program and serves as the operational center for TWS of the Pacific issuing bulletins and warnings to participating members and other nations in the Pacific Ocean area of responsibility. It is also the regional (local) warning center for the State of Hawaii. The other tsunami warning center is the National Tsunami Warning Center (NTWC) in Palmer, Alaska, serving all coastal regions of Canada and the United States except Hawaii, the Caribbean Sea and the Gulf of Mexico. The PTWC was established in 1949, following the 1946 Aleutian Island earthquake and a tsunami that resulted in 165 casualties in Hawaii and Alaska. The PTWC uses seismic data as its starting point, but then takes into account oceanographic data when calculating possible threats. Tide ga ...

National Tsunami Warning Center
The National Tsunami Warning Center (NTWC) forms part of an international tsunami warning system (TWS). It serves as the operations center for all coastal regions of Canada and the United States, except Hawaii, the Caribbean, and the Gulf of Mexico. Headquartered in Palmer, Alaska, it is operated by the National Oceanic and Atmospheric Administration, National Oceanic and Atmospheric Administration (NOAA). The NTWC detects and analyzes earthquakes worldwide, issuing warnings to local officials in the hazard zones about the advisability of evacuating low-lying coastal areas and moving ships to deep water. History Following the March 27, 1964 Alaska earthquake and tsunami, the NTWC (formerly known as The Palmer Observatory) was established in 1967 in Palmer, Alaska, under the auspices of the U.S. National Geodetic Survey, Coast and Geodetic Survey. This earthquake alerted State and Federal officials that a facility was necessary to provide timely and effective tsunami warnings and ...

Gold Medal
A gold medal is a medal awarded for highest achievement in a non-military field. Its name derives from the use of at least a fraction of gold in form of plating or alloying in its manufacture. Since the eighteenth century, gold medals have been awarded in the arts, for example, by the Royal Danish Academy of Fine Arts, usually as a symbol of an award to give an outstanding student some financial freedom. Others offer only the prestige of the award. Many organizations now award gold medals either annually or extraordinarily, including various academic societies. While some gold medals are solid gold, others are gold-plated or silver-gilt, like those of the Olympic Games, the Lorentz Medal, the United States Congressional Gold Medal and the Nobel Prize medal. Nobel Prize medals consist of 18 karat green gold plated with 24 karat gold. Before 1980 they were struck in 23 karat gold. Military origins Before the establishment of standard military awards, e.g., the Medal of Honor, ...

NDBC
The National Data Buoy Center (NDBC) is a part of the National Oceanic and Atmospheric Administration's (NOAA) National Weather Service (NWS). NDBC designs, develops, operates, and maintains a network of data collecting buoys and coastal stations. The NDBC is located in southern Mississippi as a tenant at the John C. Stennis Space Center, a National Aeronautics and Space Administration (NASA) facility. Operations NDBC employs engineers, meteorologists, oceanographers, computer scientists, and other professionals. NDBC provides hourly observations from a network of about 90 buoys and 60 Coastal Marine Automated Network (C-MAN) stations to help meet these needs. All stations measure wind speed, direction, and gust; atmospheric pressure; and air temperature. In addition, all buoy stations, and some C-MAN stations, measure sea surface temperature and wave height and period. Conductivity and water current are measured at selected stations. A new task is the operation of the DART ...

Deep-ocean Assessment And Reporting Of Tsunamis
Deep-ocean Assessment and Reporting of Tsunamis (DART) is a component of an enhanced tsunami warning system. By logging changes in seafloor temperature and pressure, and transmitting the data via a surface buoy to a ground station by satellite, DART enables instant, accurate tsunami forecasts. In Standard Mode, the system logs the data at 15-minute intervals, and in Event Mode, every 15 seconds. A 2-way communication system allows the ground station to switch DART into Event Mode whenever detailed reports are needed. Stations 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 National Data Buoy Center, and NOAA's Pacific Marine Environm ...

Buoy
A buoy () is a floating device that can have many purposes. It can be anchored (stationary) or allowed to drift with ocean currents. Types Navigational buoys * Race course marker buoys are used for buoy racing, the most prevalent form of yacht racing and power boat racing. They delimit the course and must be passed to a specified side. They are also used in underwater orienteering competitions. * Emergency wreck buoys provide a clear and unambiguous means of temporarily marking new wrecks, typically for the first 24–72 hours. They are coloured in an equal number of blue and yellow vertical stripes and fitted with an alternating blue and yellow flashing light. They were implemented following collisions in the Dover Strait in 2002 when vessels struck the new wreck of the . * Ice marking buoys mark holes in frozen lakes and rivers so snowmobiles do not drive over the holes. * Large Navigational Buoys (LNB, or Lanby buoys) are automatic buoys over 10 m high equipped with ...
