1 Based on statistics from Climatological Atlas of the World Ocean (1982).
2 Based on NODC Temperature Profile CD-ROM.
3 WOD09 OSD dataset includes data from 121,763 low-resolution CTD casts and 1,489 low-resolution XCTD casts.
4 WOD09 CTD dataset includes data from 5,985 high-resolution XCTD casts.
5 WOD09 MBT dataset includes data from 80,325 DBT profiles and 5,659 Micro-BT profiles.
6 Surface data are represented differently from profile data in the database – all observations in a single
cruise have been combined into one “cast” with zero depth, value(s) of variable(s) measured, latitude, longitude,
and Julian year-day to identify data and position of individual observations.
