roaring forties

Earth science; Physical oceanography

The region between 40 and 50° S latitude where the prevailing westerly winds blow largely unobstructed by land over the open oceans, and also the winds themselves. They are ...

Greenland Sea

Earth science; Physical oceanography

The regional sea in the North Atlantic Ocean which comprises the waters in the Greenland Basin. The average depth is about 2866 m. In the summer, the volume of the Greenland Sea ...

polarization relations

Earth science; Physical oceanography

The relationships between the velocity components and pressure for a progressive wave. They are found by substituting the assumed wave form into the relevant equations.

continental slope

Earth science; Physical oceanography

The relatively steep slope usually found between the continental shelf and the abyssal plain. Continental slopes range from 3 to 6° in slope (with 4° being about average), range ...

precision

Earth science; Physical oceanography

The repeatability of an instrument, measured by the mean deviation of a set of measurements from the average value. Contrast this to accuracy. As an example of the difference, an ...

isobaric coordinates

Earth science; Physical oceanography

The replacement of the z coordinate in an x-y-z coordinate system with the pressure. This can be done when horizontal scales are large compared to vertical scales, i.e. when the ...
