Dissolved oxygen solubility tables
- Version 3.5 -- 2013/01/14
- Made another slight change to the headers of the web pages, and fixed the
contact info in the footer. This change has no effect on the calculations.
- Version 3.4 -- 2013/01/07
- Made a slight change to the headers of the web pages. This change
has no effect on the calculations.
- Version 3.3 -- 2012/01/27
- Fixed a small problem in one of the footer files. This change has
no effect on the calculations.
- Version 3.2 -- 2011/09/12
- Fixed a bug in the routines that handled barometric pressure in units
of inches of mercury (in Hg). Results from versions 3.0 and 3.1 in
those units were erroneous.
- Version 3.1 -- 2011/08/29
- Minor change to the tabled HTML output to improve the printing of
tables from a web browser. If the browser allows, the tables printed
from a browser now will retain the column headings on every page.
- Version 3.0 -- 2011/05/13
- Major upgrade. Discarded the Weiss (1970) equations in favor of
the Benson and Krause (1980, 1984) equations. Added single-value
oxygen solubility and percent saturation as well as error checking
and unit conversions. Added the ability to input in different units
for water temperature, barometric pressure, and salinity. Added new
output formats that are friendlier for importing into spreadsheets.
- Version 2.1 -- 2008/07/16
- Minor formatting adjustment for the column labels to prevent
them from abutting each other, which occurred with certain settings.
- Version 2.0 -- 2008/07/16
- Some streamlining of formatting code.
- Version 1.3 -- 2001/08/28
- Added security checks; removed deprecated code.
- Version 1.2 -- 1999/03/16
- Improved efficiency of code; eliminated redundant calculations
performed if maximum specific conductance entered exceeds 76,000
and added warning message regarding exceeding maximum; corrected
problem with code in handling starting temperature or temperature
increment with fractional part; corrected off-by-one error in
determining number of columns to print in salinity correction
factors table; improved error checking and handling.
- Version 1.1 -- 1998/03/02
- Modified code to insert commas in atmospheric pressure and
specific conductance values greater than 999.
- Version 1.0 -- 1997/10/20
- Original web implementation; conversion from Fortran.
