Is there any algorithm description for SeaDAS OCSSW?

I found some Algorithm Descriptions in tnis website(https://oceancolor.gsfc.nasa.gov/atbd/)
but I'm not sure it's for OCSSW.

Those are algorithms for the products we are providing on ocean color website, which are also the product algorithms used in L2 gen.
By algorithm description for SeaDAS OCSSW, what are you looking for? Different algorithms or how OCSSW works?
Here is the link to the description and help page for OCSSW:

Thanks for your reply.

What I find is the Algorithms(or the related code?) of all functions such as "modis_L1B,modis_GEO,l2gen,..." in OCSSW.

the source code is not accessible:

git clone https://oceandata.sci.gsfc.nasa.gov/rcs/obpg/ocssw.git [optional target directory name]

Our git repositories are not accessible to the public. You can use SeaDAS to install a released version of the source code. Use the SeaDAS GUI to install the OCSSW src.

The code is also available on the web if you want to browse:
https://oceancolor.gsfc.nasa.gov/docs/ocssw/ocssw_src
