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 waters.
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.
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 ...
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). [2] The objectives of the mission are to make the first global survey of the Earth's surface water, to observe ...
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 ...
Marine weather forecasting is the process by which mariners and meteorological organizations attempt to forecast future weather conditions over the Earth 's oceans. Mariners have had rules of thumb regarding the navigation around tropical cyclones for many years, dividing a storm into halves and sailing through the normally weaker and more ...
Marine radar. Animation of typical rotating X band marine radar antenna on ship. It radiates a narrow vertical fan-shaped beam of microwaves perpendicular to the long axis of the antenna, horizontally out to the horizon. With each rotation the beam scans the surrounding surface. Any ships or obstructions reflect microwaves back to the antenna ...
The Sea-Based X-Band Radar underway. The Sea-Based X-Band Radar ( SBX-1) is a floating, self-propelled, mobile active electronically scanned array early-warning radar station designed to operate in high winds and heavy seas. It was developed as part of the United States Department of Defense Missile Defense Agency's (MDA) Ballistic Missile ...
