Minimum depth: Difference between revisions

Latest revision as of 16:10, 6 June 2024

The minimum depth is important for several reasons:

Vertical profilers need about one body length to accelerate to about 80% of their asymptotic speed. Thus, a minimum depth of about two body lengths is recommended.
The hull of the ship used to deploy a vertical profiler may reach several meters and data from less than hull depth should be excluded. While a glider is at the surface, shear probe data has no value.
A minimum depth of 1 to 2 m should be applied to gliders (in dives) to exclude data that are not useful for dissipation rate estimation.
