So, did they ever decide if this was a spill or not? I'm guessing not, as I haven't seen any further news about it.
Going back to the previous spill for a moment, BP is receiving some praise for one of their plans to deal with the spill. This news article is a little confusing to me:

There was apparently a fear that the underwater environment would be seriously deprived of oxygen and become sterile. It seems that's not happening, which is good news for all the sea life in the area.
