RESULTS of VERTICAL PROFILING FIELD TEST
The vertical profiling application was conducted at two test sites in the northern Gulf of
Mexico onboard the R/V
Acadiana
(Louisiana Universities Marine Consortium) over the course
of two days. One profile was conducted just outside Terrebonne Bay (29.0465N, 90.5568W) to
provide a contrast of high CDOM coastal waters. Five profiles were conducted at a second site
that was located near a known submerged shipwreck presently leaking oil from a depth of
approximately 25 m (28.56N, 90.98W; see Photo 9).

Site 2 for vertical profiles within the Gulf of Mexico located near a submerged, leaking diesel
barge.
Ancillary physical-chemical conditions and discrete reference samples were collected
with a standard CTD Rosette and Niskin bottles (Photo 10). At site 1 only a single surface depth
was sampled. At site 2, five discrete depths were sampled with one depth sampled in duplicate
for each cast. At site 2, casts were taken within and immediately surrounding the area with an
observable oil slick on the surface of the water (Photo 10).
