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 ...
NOAA ship Delaware II in foul weather on Georges Bank. Sea State 5 and 8 range. In oceanography, sea state is the general condition of the free surface on a large body of water—with respect to wind waves and swell—at a certain location and moment. A sea state is characterized by statistics, including the wave height, period, and spectrum ...
Jason-3 is a satellite altimeter created by a partnership of the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT) and National Aeronautic and Space Administration (), and is an international cooperative mission in which National Oceanic and Atmospheric Administration (NOAA) is partnering with the Centre National d'Études Spatiales (CNES, French space agency).
The RMS wave height, which is defined as square root of the average of the squares of all wave heights, is approximately equal to H s divided by 1.4. [2] [8] For example, according to the Irish Marine Institute: [9] "… at midnight on 9/12/2007 a record significant wave height was recorded of 17.2m at with [sic] a period of 14 seconds."
is the height of the satellite above the ocean surface and is the quantity measured by the satellite with cm precision. h g e o i d {\displaystyle h_{geoid}} is the local height difference between the geoid and the reference ellipsoid which is in the order of ±100 cm and can be estimated using a time series of ocean altimetry data.

Seasat [3] was the first Earth-orbiting satellite designed for remote sensing of the Earth's oceans and had on board one of the first spaceborne synthetic-aperture radar (SAR). ). The mission was designed to demonstrate the feasibility of global satellite monitoring of oceanographic phenomena and to help determine the requirements for an operational ocean remote sensing satellite sys
