Giant Undersea Volcano Found Off Iceland

22 Apr 08 - A giant underwater volcano lies just offshore of Iceland on the Reykjanes Ridge, volcanologists have announced.


"We were doing a normal oceangoing mission, and we found a big edifice" about 90 miles (150 kilometers) south of Iceland, said Ármann Höskuldsson, a University of Iceland volcanologist who was part of the international team that discovered the volcano last summer.


It’s an active volcano rising about 3,300 feet (1,000 meters) above the surrounding sections of the ridge, coming within 1,300 feet (400 meters) of the surface.


At its base the volcano is approximately 30 miles (50 km) across, with a caldera that is 6 miles (10 km) wide.


That indicates that the mountain is being fed by its own magma chamber, Höskuldsson said.


Mostly, the find indicates how little is known about the seafloor, Höskuldsson said.  


               And we think humans are heating the oceans.

14 Jul 08 - It's mid-summer and Lake Superior is still chilly.  Mid-lake buoy temperatures usually warm up quickly from early July on.  So far as of Monday, water temperatures at these buoys are barely above spring-time levels, running from the upper 30s at the northern and northeastern buoys to the low 40s at the western buoy. 

If you are a lake watcher, you have probably noticed that the water level has come up, too.  As of this past Sunday, the level of Lake Superior is 601.7 feet.  That's 1.3 feet above the average of last year and less than five inches below the long-term average.  Lake Superior's level is primarily influenced by precipitation in its watershed and there has been abundant snow and rain over the last six-to-nine months.

Both the water level and water temperatures are much different than last year.  This CNN story written just over a year ago, told of disturbingly low water levels and unprecedented warm water temperatures.  The specter of global warming was raised in explaining these phenomena in this story.  

A more level-headed report here showed how before the days of sophisticated computer models, lake observers knew there were cyclical rises and falls in the level of Lake Superior. This year, I suspect we will not hear much about Lake Superior water temperatures or levels.  "Average" or "normal" isn't newsworthy.
