Dye Tracer Experiment
May 26 - June 06, 1997
A dye tracer, Rhodamine-WT, injected into the
bottom boundary layer at the foot of the shelfbreak
front in the Middle Atlantic Bight is being used to
investigate small scale mixing and circulation near
the frontal boundary. The study area is near the ONR
CM&O mooring on the outer shelf south of Marth's Vineyard,
and although funded by NSF the project is associated with
the CM&O program. Results from a pilot cruise June 1996
(see accompanying GRL manuscript) demonstrate the utility
of the technique and provide evidence for the first time
of convergent flow associated with the frontogenesis. The
full experiment is scheduled for May 26-June6, 1997 on the
R.V. OCEANUS.
