DEPTH DEFINITIONS:
Horizontal line
Observed level/depth The depth or pressure at which an in situ measurement was collected as reported by the originator of the data.
Horizontal line
Standard level/depth A depth below the sea surface at which water properties should be measured and reported, either directly or by interpolation. The standard depths recommended according to the proposal by the International Association of Physical Oceanography in 1936 are included, with additional depths of interest added - with more closely spaced depths nearer the surface.
