Moored Time Series Measurements of the Vertical Structure of Optical Properties in the Coastal Ocean

Abstract

We have collected a remarkable data set with a very high percentage of data return. The eye of Hurricane Edouard passed within roughly 80 km of our mooring on September 1-2, 1996 and soon after Hurricane Hortense passed within roughly 250 km of our mooring on September 14, 1996. With the passage of Edouard, the mixed layer deepened very rapidly with temperature differences from the top to bottom (68m) decreasing from 12 deg C to about 2 deg C. Sediment resuspension was dramatic as well and is easily seen in all optical data, including the AC-9 data. The resuspension event is evident from 68m clear up to the 10m depth! Surprisingly, Hortense's passage resulted in significant sediment resuspension despite its relatively great distance from the mooring site (please see web site http://www.icess.ucsb.edu/opl/cmo.html).
