SCW17 Acronym Glossary

Published

June 8, 2026

Scope

This glossary is a working aid for SCW17 jack mackerel materials and related SPRFMO repositories. It was compiled from local text and report sources in:

/Users/jim/_mymods/sprfmo/scw17
/Users/jim/_mymods/sprfmo/jjm
/Users/jim/_mymods/sprfmo/JM_SCW_prep

It is intended to make draft papers, schedules, MSE notes, and benchmark material easier to read. It is not a controlled vocabulary. Definitions and formal names should be checked against adopted SPRFMO reports before final submission.
