In the ocean, this leads to a vertical separation of nitrification from primary production, and confines it to the aphotic zone.

Movement of the upper slope gradually increased into a continuous headscarp approximately long with a vertical separation of by June 1998.

The vertical separation ( distance ) between parallel trajectories is the vehicle spacing ( s ) between a leading and following vehicle.
15.
As a result, the Cessna had been below the MAS aircraft more than 2, 000 feet vertical separation although it was behind.

In 1958 the standard vertical separation was set to 1, 000 feet from the surface to FL290, and 2, 000 feet above FL290.
17.
Other planes can seem quite close while still obeying the vertical separation rules & mdash; I've been taken by surprise at times, too.
18.
This cuts the vertical separation to between about and 41, 000 feet ( the exact limits vary slightly from place to place ).
19.
This is a result of the vertical separation of the matching curved branch that formed the cruck, after being cut from a tree ..
20.
The vertical separation between aircraft is either 300 metres or 600 metres ( about 1.6 % less than 1, 000 or 2, 000 feet ).
