Fluorescent Dye Tracer Studies of the Coastal Mixing and Optics (CMO) Program from Lamont Doherty Earth Observatory (LDEO)
Entry ID: CMO_LDEO_DYE_MIXING

[ Update this Record ]

Summary
Abstract: As part of the Coastal Mixing and Optics (CMO) Program, Lamont-Doherty
Earth Observatory (LDEO) of Columbia University performed tracer
studies using fluorescent dyes to study small scale mixing and
circulation near a frontal boundary.

A fluorescent dye tracer, Rhodamine-WT, was injected from a towed sled
into the benthic boundary layer (BBL) at the foot of the shelfbreak
front in the Middle Atlantic Bight. The initial dye patch was a 1-km
streak, parallel to the 100 meter isobath, just on the shoreward side
of the center of the front. The subsequent dispersal of the dye patch
in the BBL was mapped for the next 3 days.

The experiment was conducted near the CMO study area of the
Mid-Atlantic Bight, 80 miles southeast of Montauk, Long Island, and 60
miles south of Martha's Vineyard.

The dye tracer technique provided evidence for the first time of
convergent flow associated with the genesis of the front.
