Tuesday, January 24th, 2012 -- Volcanoes in Virginia!

The recent earthquake may have you wondering what other surprises  
Virginia's geology may hold. Could there be a volcanic eruption in  
Virginia? Probably not today, but during the Eocene, about 35-48  
million years ago, a number of mysterious eruptions occurred in  
western Virginia. This talk investigates the possible origins of these  
eruptions, and what they can tell us about the crust and mantle  
underneath Virginia.

Tuesday, February 7th, 2012 -- Living and Working in the Freezer

Very little data of any kind exists from the early spring in the  
Arctic. The reason? It's extremely cold and that makes it difficult to  
survive, let alone conduct science. From March through the end of  
April, 2011, scientists from around the world braved temperatures of  
-48°C in the high Canadian Arctic in the name of science. At the  
Catlin Arctic Survey's floating 'Ice Base' off Ellef Ringnes Island,  
Dr. Victoria Hill was investigating how organic material in fresh  
water near the surface of the ocean may be trapping heat from the sun,  
causing the upper ocean layers to warm. This is a very new area of  
research and this mechanism represents a key uncertainty in accurate  
modeling of ice thickness and upper ocean heat content. In this  
presentation Dr. Hill will talk about living and working at the ice  
base and discuss preliminary data from the expedition.

Lectures are free and open to students and adults with an interest in  
science. All lectures begin at 7:00 pm in CEBAF Center Auditorium and  
last for about an hour. Seating in the CEBAF Center Auditorium and  
overflow area is limited to about 300 people. Seating is on a first  
come, first served basis. Unfortunately, people arriving once capacity  
has been reached will be turned away.


Due to security concerns, persons 16 years old or older may need to  
show a picture ID to Lab Security Officers. Vehicles and hand carried  
items may be inspected.


Not able to attend in person? Don't forget that the Science Series is  
streamed live (http://education.jlab.org/live/) as well as available  
on-demand from the Science Series Video Archive (http://education.jlab.org/scienceseries/archive.html 
), pending approval from the speaker.


Maps to Jefferson Lab's CEBAF Center Auditorium, as well as additional  
information about the Science Series, can be found on the Science  
Education web site:
