The "WoceBtl" collection contains hydrographic, nutrient and tracer data from the one-time and repeat WOCE Hydrographic Program (*_hy1.csv files from WHPO web-site as of May/27/2002). Also included are more than 2000 stations from pre-WOCE cruises. Note that the WOCE data have been scanned for outliers using the automatic and interactive methods of the ODV software. As a result of this procedure, a number of data have been marked questionable or bad. See the file WoceBtl.log for a log of these changes. For more information see the cruise reports in subdirectory "doc" and the "whp" directory of the WOCE Global Data, Version 3.0 disks.
