Chemicals dissolved in those vents influence ocean chemistry and sustain a complex web of organisms, much as sunlight does on land. In recent decades more than 220 vents have been discovered worldwide, but so far no one has looked for them in the rough and frigid waters off Antarctica.<\/p>\n<p>From her lab in Palisades, N.Y., geochemist Gisela Winckler recently took up the search. By analyzing thousands of oceanographic measurements, she and her Lamont colleagues pinpointed six spots on the remote Pacific Antarctic Ridge, about 2,000 miles from New Zealand, the closest inhabited country, and 1,000 miles from the west coast of Antarctica, where they think vents are likely to be found. The sites are described in a paper published in the journal <em>Geophysical Research Letters<\/em>.<\/p>\n<p>&#8220;Most of the deep ocean is like a desert, but these vents are oases of life and weirdness,&#8221; said Winckler. &#8220;The Pacific Antarctic ridge is one of the ridges we know least about. It would be fantastic if researchers were to dive to the seafloor to study the vents we believe are there.&#8221;<\/p>\n<p><a href=\"http:\/\/www.sciencedaily.com\/releases\/2010\/03\/100303114012.htm\" >Read more &gt;&gt; <\/a><\/p>\n<p class=\"akst_link\"><a href=\"http:\/\/www.earthportal.org\/news\/?p=3171&amp;akst_action=share-this\"  title=\"E-mail this, post to del.icio.us, etc.\" id=\"akst_link_3171\" class=\"akst_share_link\" rel=\"nofollow\">Share This<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Science Daily: Scientists at Columbia&#8217;s Lamont-Doherty Earth Observatory have found evidence of hydrothermal vents on the seafloor near Antarctica, formerly a blank spot on the map for researchers wanting to learn more about seafloor formation and the bizarre life forms drawn to these extreme environments.
