The sweeping, diagonal line is the CODAR signal. Coastal ocean dynamics applications radar (CODAR) is a type of portable, land-based, high frequency (HF) radar developed between 1973 and 1983 at NOAA 's Wave Propagation Laboratory in Boulder, Colorado. CODAR is a noninvasive system that can measure and map near-surface ocean currents in coastal ...
The Surface Water and Ocean Topography (SWOT) mission is a satellite altimeter jointly developed and operated by NASA and CNES, the French space agency, in partnership with the Canadian Space Agency (CSA) and UK Space Agency (UKSA). [4] The objectives of the mission are to make the first global survey of the Earth's surface water, to observe ...
Ocean dynamics. Ocean dynamics define and describe the flow of water within the oceans. Ocean temperature and motion fields can be separated into three distinct layers: mixed (surface) layer, upper ocean (above the thermocline), and deep ocean. Ocean dynamics has traditionally been investigated by sampling from instruments in situ.
PACE mission logo. Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) is a 2020s NASA Earth-observing satellite mission is observing global ocean color, biogeochemistry, and ecology, as well as the carbon cycle, aerosols and clouds. [3] PACE is intended to be used to identify the extent and duration of phytoplankton blooms and improve ...
Wave radar. Measuring ocean waves by use of marine radars. Wave radar is a type of radar for measuring wind waves. Several instruments based on a variety of different concepts and techniques are available, and these are all often called. This article (see also Grønlie 2004), gives a brief description of the most common ground-based radar ...
Ocean surface topography is used to map ocean currents, which move around the ocean's "hills" and "valleys" in predictable ways. A clockwise sense of rotation is found around "hills" in the northern hemisphere and "valleys" in the southern hemisphere. This is because of the Coriolis effect. Conversely, a counterclockwise sense of rotation is ...
A man standing next to large ocean waves at Porto Covo, Portugal Video of large waves from Hurricane Marie along the coast of Newport Beach, California. In fluid dynamics, a wind wave, or wind-generated water wave, is a surface wave that occurs on the free surface of bodies of water as a result of the wind blowing over the water's surface.
Ocean current. Distinctive white lines trace the flow of surface currents around the world. An ocean current is a continuous, directed movement of seawater generated by a number of forces acting upon the water, including wind, the Coriolis effect, breaking waves, cabbeling, and temperature and salinity differences.
