Bottom interference
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

.. toctree::
   :maxdepth: 2


Sometimes when the bottom is too close to the instrument or near the
end of the instrument's range, the UHDAS automated  at-sea processing 
cannot identify the bottom by a simple algorithm.  There may be 
artifacts left in the ocean velocities, which should be edited out by 
hand.
