  2. Vector measuring current meter - Wikipedia

    en.wikipedia.org/wiki/Vector_measuring_current_meter

    A vector measuring current meter (VMCM) is an instrument used for obtaining measurements of horizontal velocity in the upper ocean, which exploits two orthogonal cosine response propeller sensors that directly measure the components of horizontal velocity. [1]

  3. Relative wind stress - Wikipedia

    en.wikipedia.org/wiki/Relative_wind_stress

    As illustrated on the top part of Figure 3, in the eddy situation, the relative wind stress is smaller when the wind and ocean velocities are aligned, a similar situation to the top part of Figure 2. At the bottom part of Figure 3 we have a situation analogous to the bottom part of Figure 2, where more negative work is being performed on the ...

  4. SRTM Water Body Data - Wikipedia

    en.wikipedia.org/wiki/SRTM_Water_Body_Data

    Demo map showing high-resolution SWBD coastlines. The SRTM Water Body Data (SWBD) is a geographical dataset (2003) encoding high-resolution worldwide coastline outlines in a vector format, published by NASA and designed for use in geographic information systems and mapping applications.

  5. Mini-automatic radar plotting aid - Wikipedia

    en.wikipedia.org/wiki/Mini-automatic_radar...

    Mini-automatic radar plotting aid (or MARPA) is a maritime radar feature for target tracking and collision avoidance. Targets must be manually selected, but are then tracked automatically, including range, bearing, target speed, target direction (course), CPA (closest point of approach), and TCPA (time of closest point of approach), safe or dangerous indication, and proximity alarm.

  6. Marine current power - Wikipedia

    en.wikipedia.org/wiki/Marine_current_power

    Vector Diagram of current flow along the east coast of the United States. The total worldwide power in ocean currents has been estimated to be about 5,000 GW, with power densities of up to 15 kW/m2. The relatively constant extractable energy density near the surface of the Florida Straits Current is about 1 kW/m2 of flow area.

  7. Vector Map - Wikipedia

    en.wikipedia.org/wiki/Vector_map

    The Vector Map (VMAP), also called Vector Smart Map, is a vector-based collection of geographic information system (GIS) data about Earth at various levels of detail. Level 0 (low resolution) coverage is global and entirely in the public domain. Level 1 (global coverage at medium resolution) is only partly in the public domain.

  8. General Bathymetric Chart of the Oceans - Wikipedia

    en.wikipedia.org/wiki/General_Bathymetric_Chart...

    GEBCO is the only intergovernmental body with a mandate to map the whole ocean floor. At the beginning of the project, only 6 per cent of the world's ocean bottom had been surveyed to today's standards; as of June 2022, the project had recorded 23.4 per cent mapped. About 14,500,000 square kilometres (5,600,000 sq mi) of new bathymetric data ...

  9. Ocean observations - Wikipedia

    en.wikipedia.org/wiki/Ocean_observations

    NOAA NODC WOA05 is the World Ocean Atlas 2005, an atlas of objectively analyzed fields of major ocean parameters at monthly, seasonal, and annual time scales. In situ observations spanning from the early 1700s to present are available from the International Comprehensive Ocean Atmosphere Data Set (ICOADS).
