“Ancient Air” & “Core Science”
August 22, 2012 | International Innovation
Two articles in International Innovation feature engineering professor Mary Albert, Th ’83, and her polar ice sheet research team's study of “firn,” a term for Arctic snow that serves as “an archive of past atmospheric composition, and the relationships between the physical structure of the firn and gas trapping process.”
Brave New World—medical devices use biometrics to prevent hack attacks
August 7, 2012 | Ars Technica
Computer scientists—including engineering professor Ryan Halter—have proposed a wearable healthcare device that uses unique physiological signatures in a patient's heart rate or other physiological response to prevent tampering by malicious hackers.
An inside look at Greenland’s melting surface ice
August 3, 2012 | The Washington Post
Engineering Ph.D. candidate Kaitlin Keegan and Professor Mary Albert are featured in this article about Greenland’s big mid-July “melt” that gave polar scientists a chance to study a rare warming event as it was happening.
New Probe Provides Vital Assist in Brain Cancer Surgery
July 24, 2012 | Dartmouth-Hitchcock
MD/PhD student Pablo Valdes worked with David Roberts and Keith Paulsen to help develop a probe that uses an innovative fluorescence-reading technology to help brain surgeons distinguish cancerous tissue from normal tissue.
Greenland ice sheet had biggest thaw since 1973 this month, scientists say
July 24, 2012 | The Washington Post
Dartmouth engineering Ph.D. student Kaitlin Keegan, who has sampled ice cores taken from Summit Station in central Greenland, said ice core samples indicate such pronounced melting at Summit and across the ice sheet has not occurred since 1889.
IGERT Graduate Student Adds to Critical NASA Discovery
July 24, 2012 | Dickey Center
Research by Dartmouth Thayer School of Engineering graduate student Kaitlin Keegan has added critical information to a NASA annoucement regarding melting of the Greenland Ice Sheet.
Giant algae blooms thriving under thinning Arctic sea ice
June 12, 2012 | CBC News (Canada)
Visiting Professor of Engineering Donald Perovich and his colleagues discovered enormous blooms of algae growing in an area of the Arctic Ocean that they never thought could support the phytoplankton: below the sea ice.
Tiny undersea plants may affect Arctic ocean life
June 8, 2012 | San Francisco Chronicle
Visiting Professor of Engineering Donald Perovich and his colleagues discovered a massive bloom of the microscopic marine plants called phytoplankton beneath the sea ice—a discovery that could affect the life of every seagoing creature in the Arctic.
Thinning Arctic Ice Allows Plankton Bloom
June 8, 2012 | Scientific American
Visiting Professor of Engineering Donald Perovich participated in an expedition through the Chukchi Sea off the coast of Alaska that found massive blooms of phytoplankton under the ice. The discovery upends the notion that the sea ice that forms in autumn ushers in a nearly lifeless season for the ocean below.
NASA Discovers Unprecedented Blooms of Ocean Plant Life
June 7, 2012 | NASA
Visiting Professor of Engineering Donald Perovich participated in a NASA-sponsored expedition that punched through three-foot thick sea ice to find waters richer in microscopic marine plants, essential to all sea life, than any other ocean region on Earth.
