What would be really interesting is the list of species present, that can bring some nice things.
My bet would be that the community will be just an extension of the marine ecosystems near, with mostly the same species, maybe with a nice set of new microbes. Maybe similar to glacier communities and probably communicated with the sea in some way.
But a new ecosystem in the planet is a really exciting thing.
This is a linguistic observation and completely beside the point, but there's an interesting difference between each and every: each implicitly involves a set of specific things, things individually identifiable in some context. If you say "each person has two parents" the hearer will assume you're already talking about some set of individuals, the ones in the room, say. If you say "every person has two parents" they will think you are making a generalization about people, including hypothetical people who have not been born, ancient people who left no trace in history, and so forth.
Sure, until you use the phrase, "every person in this room has two parents".
