Right, and thanks to all that time studying it is very likely that whatever is in the pond is nothing new. Which is kind of the point of the article. Whatever is in the pond is most likely nothing we haven't seen before. Now, studying the depths of the Arctic is a different matter. Are you saying that we are so rare (just like Arctic species hundreds of meters below ice) that aliens will rush to study us?
The whole point is that we are probably average, just like the life in the pond is probably average, which is the reason nobody will put us on their priority list.
Your premise is invalid.
