Title: Fluorescent Dye Tracer Studies of the Coastal Mixing and Optics (CMO) Program from Lamont Doherty Earth Observatory (LDEO)
Description:
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. [This information was obtained from the Observational Physical Oceanography website at LDEO.]
