beta spiral method
Earth science; Physical oceanography
An inverse method for determining the oceanic velocity field where the motion is geostrophic and the potential vorticity locally balanced. This method provides a mechanism for ...
bucket temperature
Earth science; Physical oceanography
The surface temperature of the ocean as measured by a bucket thermometer. This can also be the temperature measured by immersing a surface thermometer into a freshly drawn bucket ...
isotope stage
Earth science; Physical oceanography
A division of a deep-sea core on the basis of oxygen isotope ratios. There have been 19 isotope stages since the reversal of the Earth's magnetic field 700,000 years ago.
isotope
Earth science; Physical oceanography
Each of two or more varieties of a particular chemical element which have different numbers of neutrons in the nucleus, and therefore different relative atomic masses and ...
oceanic expeditions
Earth science; Physical oceanography
The deep-sea expeditions that have taken place through the history of ocean sciences have been grouped into four eras: * Era of Exploration (1873-1914) * Era of National ...
ocean stratosphere
Earth science; Physical oceanography
The lower layer of the ocean as defined by Defant in 1928. The stratosphere is a sluggish, cold layer which is homogeneous vertically and horizontally in its basic properties. It ...
