The Phaeophyceae or brown algae, is a large group of mostly marine multicellular algae, including many seaweeds of colder Northern Hemisphere waters. They play an important role in marine environments, both as food and for the habitats they form.
[note: GeoRef uses Phaeophyta to refer to all seaweed, not just brown.]
Geological keywords, such as “granite”, “lake”. The definitions are generally taken from the AGI Glossary of Geology. Keywords with a geographic context (e.g. Cape Smith Fold Belt, Selwyn Basin, Grenville Province) are assigned to a separate category.
