bathymetry

 PI:              Robert Anderson
 of:              Lamont-Doherty Earth Observatory

 dataset:         Ross Sea, Antarctic Polar Front Zone standard depths
 project/cruise:  AESOPS -  all cruises
 ship:            Nathaniel B. Palmer
 
 PI-Note:  AESOPS Investigators presenting AESOPS data may use these data
	   as a standardized bathymetry of the research area. The 76deg30min
	   transect represents the standardized bathymetry in the Ross Sea.
	   The 170degW transect is the full AESOPS transect from the Ross
	   Sea to New Zealand.

   76.5S   All data within .5 mile on either side of 76.5S were extracted
	   from the daily underway (jgdata) files recorded during cruises
	   nbp9605 and nbp9701.  It was then sorted by longitudes and 
	   subsampled to 1 minute of longitude using Akima's spline for
	   interpolation.  A GIF image is also available.

   170W    Bathymetry data collected during nbp9802 were sorted by latitude
	   and smoothed using a Robust median filter of 1.08 minutes of
	   latitude.  Then, the data were output at a resolution of .36
	   minutes of latitude.   A GIF image is also available as well as
           some higher resolution quarter section GIFs along 170W:
	     first quarter section 
	     second quarter section 
	     third quarter section 
	     fourth quarter section 

   All GIF images were generated by Suzanne O'Hara (LDEO).
