    Irish Chronicles Document Links Between Volcanoes and Weather

    A study of over 40,000 written entries in Irish Annals and ice core measurements shows a strong correlation between the occurrence of volcanic eruptions and extreme cold weather in Ireland over a 1200 year period. Data analyzed in this study cover the period from 431 to 1649, during which time up to 48 volcanic eruptions are identified in Greenland ice core records through deposition of volcanic sulfate in annual layers of ice. You can find the study (open access), published on 6 June 2013 in IOP Publishing's journal Environmental Research Letters, at http://iopscience.iop.org/1748-9326/8/2/024035/article.

    EF-5 Tornado in El Reno, Oklahoma Widest Ever Recorded in US

    The EF-5 tornado that hit El Reno, Oklahoma on May 31st was the widest ever recorded in the US, according to the National Weather Service in Norman Oklahoma. The tornado, which remained on the ground for 40 minutes and reached 2.6 miles across (4.2 km), took the lives of 18 people including storm chasers Tim Samaras, Paul Samaras and Carl Young. For more information on the tornado, visit http://ow.ly/i/2hfDG.

    Atmospheric CO2 Level Tops 400 ppm

    During the week of May 13th, the CO2 level at the Mauna Loa Observatory in Hawaii topped 400 ppm repeatedly. Daily levels of CO2 can vary due to weather, and there are seasonal trends as well. The level of atmospheric greenhouse gases continues to increase, now over 120 ppm since the Industrial Revolution began. For more on the Keeling Curve, see http://keelingcurve.ucsd.edu/.

Houston, We Have a Phone Call!

"Alvin, this is the International Space Station Alpha, how do you hear us? Over."

These words started one of the farthest-reaching long-distance phone calls in history this afternoon when astronaut Sunita "Suni" Williams initiated a phone conversation with oceanographer Tim Shank. That may not sound remarkable - except that Suni was over 200 miles above Earth in the International Space Station while Tim was nearly two miles beneath the ocean's surface in the Alvin research submersible. Here’s Tim standing in front of Alvin prior to the dive.

The two explorers spent about 20 minutes discussing the similarities and differences between their work environments, what they each study, and what it is like to live in space and at sea. They also talked about swapping places one day, just to see what each other’s research environment is like – ah, just like a true explorer.

The phone call was recorded and broadcast over the Internet, and many of us onboard the R/V Atlantis listened in from the ship’s computer lab. You can still hear the broadcast on the web for the next few weeks. Click here to go to the Woods Hole Oceanographic Institution website for more instructions.

And don’t forget to visit the SEAS cruise log for more on this story. See the log entries on January 25th and 26th. This cruise sure is exciting!!
