 dataset:         Deep sea sediment trap particle flux
 project/cruise:  AESOPS/Southern Ocean 1996-1997 Mooring Deployment
                  Deployment: NBP 96-5 
		  Recovery: NBP 98-2 Benthic Cruise
 ship:            R/V Nathaniel B. Palmer
 
 Methods: Refer to North Atlantic Bloom Experiment (NABE)
          for a description of the time-series sediment trap arrays.

          Laboratory methodology described in NABE has been modified. 
          Contact Steve Manganini at WHOI for details.

 Note:  Each sediment trap consisted of 21 cups.  
        Only cups that contained a sample are reported in the data set.
