The Hydrographic "Service" data that is posted on the JOSS web-site is to 
be considered preliminary. 
There could be additional changes to the pressure and accordingly the depth. 

Temperature will more than likely not change even at the end of the 
expedition. We monitor the two temperature sensors and if a shift is seen 
the data cannot be corrected until a post-cruise calibration is performed.

Conductivity will be monitored by comparison of both sensors with each other
and by the bottle salinities and more than likely will be adjusted throughout 
the expedition. 

Oxygen, fluorometrics and PAR data are only intended for qualitative use. 
The transmissometer may be corrected, but only at the end of the expedition.

CTD Data:
The CTD data for all stations is included in the Zip distribution. This is 
in the WHP-Exchange format.
Individual stations are under the Station No. column, CTD_Data.csv. 
The file CTD_Comments.txt is a file that has comments that are made by
the CTD Operator at the time of the cast, and any data problems with the
solution that was done during processing.

Sample Log sheets:
Sample Log sheets are scanned and posted right after the cast. There are two 
flavors on the format. One file is a Bottle_Sample_Log.doc file, that is the
type of file the scanning software produces. The other is a 
Bottle_Sample_Log.jpg file. Steve Roberts, JOSS, produces this file for us.

Bottle Data two formats, Data report and WHP-Exchange Format:
The bottle trip information, Pressure, Depth, Temperature and Salinity will be
posted in the Bottle_Hydro_report.txt file shortly after the cast. All other
service measurements will be posted once the data comes in. The data will be
posted as soon as it is available. It may or may not have been DQ'd (Data 
Quality check).
The comments from the Sample Log sheet which may affect samples are also 
tabulated on the Data Report, ie. leak. Eventually, when all data is assembled
a decision can be made and will be reported as to whether the quality of the
data suffered or that the data is acceptable.  These comments will be made once 
all the data is assembled.

The data is coded or footnoted according to the WOCE protocal. The mnenomics 
that are seen in the Bottle Data Report have the following meaning:
btl Bottle
slt Salinity, Bottle
oxy Oxygen, Bottle
sil Silicate
no3 Nitrate
no2 Nitrite
po4 Phosphate
nh4 Ammonium
ure Urea
ct1 Conductivity and coincidently salinity, primary CTD sensor
ct2 Conductivity and coincidently salinity, secondary CTD sensor
tp1 Temperature, primary CTD sensor
tp2 Temperature, secondary CTD sensor
cto Oxygen, CTD

Codes assigned to the bottle:
3   Leaking, could be an air leak which would just affect the gas samples, O2.
4   Did not trip as scheduled, this is interpreted as all samples are bad.
9   No samples were not drawn, not only service measurements, but none of the
    other disciplines.

Codes assigned to the data:
3   Questionable.
4   Bad.
5   Not reported.
9   Not drawm.
