Scientific Purpose/Goals: Second sampling off Rio de la Plata after passage of Hurricane David to determine post-storm recovery and seasonal variation in the shelf sediments.

Start Port/Location:
End Port/Location:
Start Date: 1980-01-17
End Date: 1980-01-18
Equipment Used: Shipek grab, Echosounder, Raytheon radar, Plane table-transit-radios triangulation
Information to be Derived: Samples and chemical analysis;
Summary of Activity and Data Gathered: The first day, 29 stations were occupied and sediment was recovered. The second day, rough weather prevented further sampling and planned dives. Depth recorder indicated 10-12 sec. waves with as much as 18-foot heights in 50 feet of water. Turbid water unlike the previous day covered the entire shelf. The turbid boundary followed the contour of the shelf break, probably indicating turbidity due to wave resuspension of mud.
