Marine science, intro and chapters

This blog is for my Marine science class at Ranum Efterskole College, but if anyone else can use it, they are more than welcome.

All the content here is non profit, and all errors are mine and mine alone.

I have taught AS and A level Marine sciene since 2014, and the new IGCSE sylabus for two years

This blog will cover the Marine Science 0697 syllabus, and have small videos of my class and the stuff we do.
