Data are organized by variable. Within each variable directory, the data are stored by time period:
annual, seasonal, and monthly. Each time period directory contains the following file types:
 Analyzed mean fields (an)  onedegree alldata objectively analyzed mean.
For temperature, salinity, and oxygen, an denotes an average of either the 12 monthly analyses (used
to compute the annual analysis at and above 1500 meters), the 3 monthly analyses (used for the seasonal analyses), or
the 4 seasonal analyses (used for the annual analysis below 1500 meters). For nutrients and chlorophyll data, an
denotes the average of the 4 seasonal analyses. For annual at and above 1500 meters, this is the average of the 12 monthly
analyses, for annual below 1500 meters, this is the average of the 4 seasonal analyses, for seasonal means this is the
average of the appropriate 3 monthly analyses that comprise each season)
 Seasonal or monthly fields minus annual fields (ma)  onedegree seasonal and monthly
analyzed mean minus annual analyzed fields
 Grid point fields (gp)  onedegree number of grid points which contain data within the
radius of influence for each grid box
 Data distribution field (dd)  onedegree and fivedegree geographic distribution of data used
in analysis
 Standard deviation field (sd)  onedegree and fivedegree standard deviation from the mean
 Standard error of the mean (se)  onedegree and fivedegree standard error of the mean
 Means (mn)  onedegree and fivedegree unanalyzed means for all data used in analysis
 Unanalyzed minus analyzed (oa)  analyzed field subtracted from the onedegree
unanalyzed (raw) means
Data files have the following naming conventions:
[v][tp][ft][g][xx].gz
where:
[v] = variable:
t = temperature
s = salinity
o = dissolved oxygen
x = percent oxygen saturation
a = apparent oxygen utilization
p = phosphate
n = nitrate
i = silicate
c = chlorophyll
z = zooplankton biomass
[tp] = time period:
00 = all data annual
13  16 = seasons (starting with 13 = Winter (JanMar))
01  12 = months (starting with 01 = January)
[ft] = file type:
an = alldata analyzed mean
dd = number of observations
sd = standard deviation of data
se = standard error of the mean of data
mn = raw (unanalyzed) mean of data
oa = unanalyzed (raw) mean minus analyzed field
ma = seasonal or monthly fields minus annual fields
gp = number of grid points containing data within the radius of influence around
present grid point
[g] = grid size:
1 = onedegree square file
5 = fivedegree square file
[xx] = plankton type identifier: Only present in the plankton data files
dv = zooplankton displacement volume (ml/m^{3})
sv = zooplankton settled volume (ml/m^{3})
wm = zooplankton wet mass (mg/m^{3})
dm = zooplankton dry mass (mg/m^{3})
am = zooplankton ashfree dry mass (mg/m^{3})
cc = calculated zooplankton Carbon content (mgC/m^{3})
