I'm looking for a one-word opposite of "submerged". The context is a study where I'm looking into species that live below the surface and thus can be conveniently labeled as "Submerged" in my plot. However I can't find a good word to describe those found living on the surface (of a peat bog).
Emerged or surficial(?) comes to mind but since I'm not a native speaker I'm not too sure that I can use it that way.
