Counselor signs it off Milestone
The completion date is the date you met the requirements, not the date of the signature.
Usually comes after 1. Four branches of oceanography, and why learn about the oceans, 2. Salinity, temperature and density; currents; weather and climate and 6 others.
Merit badge requirements are republished annually. A Scout beginning work uses the requirements as they stand then; a Scout already working may finish under the ones they started with. Guide to Advancement 7.0.4.3 governs which applies. This page records the date its copy was read. Check it against the official page before relying on it.
This plan is a planning aid: the current Boy Scouts of America publication is always the authority, and the sources used here are listed in full. Each step names its own.
