Martian Sea Discovered

mpesce writes "New Scientist is reporting that a large sea of frozen ice (between 800 and 900 km in size and 45 m deep) has been discovered by the ESA's Mars Express Probe. Here's the kicker: the sea of block ice is only five degrees away from the Martian equator. New Scientist also links to a PDF of a paper to be presented next month about the finding." Update: 02/21 15:30 GMT by T : Note: that's 45 meters deep, not 45 kilometers deep.
