<p>I suspect that there was indeed an ancient ocean, but I must say at the vidence present in this story is a bit stretched.&nbsp; I'll have to wait for the paper to say more.</p><p>Jon</p> <div class="Discussion_UserSignature"> <p><em>Whether we become a multi-planet species with unlimited horizons, or are forever confined to Earth will be decided in the twenty-first century amid the vast plains, rugged canyons and lofty mountains of Mars</em>  Arthur Clarke</p> </div>

True, always good to wait for the published papers. It was noted in the original MRO article that even more buried ice is in the northern hemisphere, where the putative oceans were. Could these two findings be at all related, or completely separate things? I think the tentative former ocean findings are seemingly just as significant as the buried glaciers, although there seems to be little discussion about it yet in any of the forums. Of course, if the former oceans could be finally confirmed, that would be even more exciting than just more ice! <div class="Discussion_UserSignature"> <p><font size="1"><span style="font-weight:bold" class="Apple-style-span">-----------------</span></font></p><p><font size="1"><span style="font-weight:bold" class="Apple-style-span">The Meridiani Journal</span><br />a chronicle of planetary exploration<br />web.me.com/meridianijournal</font> </p> </div>
