Preparing Seabird CTD data for Ocean Data View (ODV)

In this post I will give a tutorial explaining the procedure I use to prepare sampled marine data (mostly SeaBird CTD data) to be plotted using the Ocean Data View (ODV) software.



Both ODV and SeaBird CTD are near Oceanographic standard, but getting used to processing the CTD data for ODV takes some time. With the hope of saving some time I detail the procedure we usually take at the Israeli School of Marine Sciences.

Step one: 
Convert the hex file downloaded frome the CTD or saved while sampling using SeaSave software to .cnv file. This step is conducted using the Data Conversion option in SeaBird data processing software (SBEDataProcessing).
Step two:
Align the CTD data. Since the CTD instrument is a combination of several sensors, each having a typical time lag the readings in one data scan does not really represent a single point in time for all water quantities. To compensate for this, CTD alignment is performed using the Align CTD option at the SBEDataProcessing.

Step three:
Average the CTD data by depth. Many times, having data values at fixed depth intervals (eg. 1m) is more convenient. To achieve that we use the Bin Average option in SBEDataProcessing.
Step four:
Exporting the data to text file. The .cnv files include header, metadata and only then the sampled values. To be separate the metadata from the data we export the data to text file using the Ascii Out option in SBEDataConversion.
Step five:
Data Validation. Many times some of the sensor reading is noisy or in someway inaccurate, before we go on with plotting the data we validate that all data are correct. This is conducted by plotting a scatter plot of the data using MS. Excel and visually observing the plots.
Step six:
Preparation of ODV compatible spreadsheet. ODV has very strict laws for importing spreadsheet data. To prepare the data in ODV format we use an MS. Excel template (you can grab it here) and save it as a delimeted text file.

Last step (seven):
Import the data to ODV and plot it.

Thanks to my teacher Gitai Yahel who tought me this process.

Seawater Oxygen saturation function for Microsoft excel

Hi all
For some time now I searched for a Microsoft oxygen saturation function with no success so I had to write one.
If you are interested, you can download the code here and paste it in a VBA Module in your workbook. Or you can just download the sample spreadsheet here:

The code:

Public Function O2Sat(ByVal T As Single, ByVal S As Single) As Single


' SW_SATO2   Satuaration of O2 in sea water
'=========================================================================
' sw_satO2 $30/12/2014 By yair Suari, Ruppin Academic Center$
'
'
' to use, Formulas>Insert Function =O2Sat(S,T,P)
'
' More:
'    Solubility of Oxygen as O2 in sea water
'
'
'   S = salinity    [psu      (PSS-78)]
'   T = temperature [degree C (IPTS-68)]
'
' Output Units:
'   O2  [ยตMol/l]
' After:
'    Weiss, R. F. 1970
'    "The solubility of nitrogen, oxygen and argon in water and seawater."
'    Deap-Sea Research., 1970, Vol 17, pp721-735
.
' convert to Kelvin
T = 273.15 + T

'constants for Eqn (4) of Weiss 1970

a1 = -173.4292
a2 = 249.6339
a3 = 143.3483
a4 = -21.8492
B1 = -0.033096
b2 = 0.014259
b3 = -0.0017

'Eqn (4) of Weiss 1970

lnC = A1 + a2 * (100 / T) + a3 * Log(T / 100) + a4 * (T / 100) + S * (B1 + b2 * (T/ 100) + b3 * ((T / 100) ^ 2))

c = Exp(lnC)
O2Sat = c / 22.414 * 1000

End Function



Happy new 2015
