Evaportie Minerals Left by Seeps not Oceans

New studies suggest that some of the minerals found in Meridiani Planum are not from oceans after all, but instead from the evaporation of seeps or springs coming out of the ground. While this indicates that there was groundwater flow, and could mean that there is still groundwater deep down, also doesn't mean that there were never oceans. It merely means that there wasn't an ocean there. To me, I think that knowing there was significant groundwater is more important than ancient oceans, mainly because oceans are obviously gone, but groundwater could still be present.
