Dickey Center Director Daniel Benjamin talks to Andrea Mitchell on MSNBC about ISIS and the threat to Iraq and Syria, and the challenge of arming individual Iraqi and Kurdish factions to fight them. He also discusses the overheated rhetoric coming out of Washington about ISIS as a threat to the US.

Watch the entire discussion on MSNBC.

August 12, 2014, Dartmouth Now

In a story about the Islamic State in Iraq and Syria (ISIS), Jake Tapper ’91, host of CNN’s The Lead with Jake Tapper, turns to Dartmouth’s Daniel Benjamin for comment about the threat posed by the militant group.

Benjamin, the Norman E. McCulloch Jr. Director of Dartmouth’s John Sloan Dickey Center for International Understanding and the former U.S. Ambassador-at-Large and Coordinator for Counterterrorism at the U.S. State Department, tells Tapper that ISIS poses “an unproven threat” to the U.S. “It’s a big concern, but at the moment, there is...

Gifford Wong

Gifford Wong, Ph.D. Student, Earth Sciences

Gifford Wong looks at the effect of climate change on the growth and decay of the Greenland Ice Sheet (GIS). He studies how changes in temperature affect our ability to assess the health of the GIS.

During the summers of 2010 and 2011, Gifford collected snow samples from pits (~2 m depth) and cores (~10-100 m depth) in the northwest GIS along a traverse route that roughly connects Thule Air Base with NEEM camp and Summit Station in Greenland. He took these samples back to the labs at Dartmouth where he prepared them for chemical... Read more.

Simone Whitecloud

Simone Whitecloud, PhD student, Ecology and Evolutionary Biology

Simone Whitecloud documents plant names and uses in order to preserve traditional knowledge. Plant ranges are changing in response to a changing climate, and her data will preserve knowledge that would otherwise be lost as plant ranges shift and practitioners lose access to the same plants.

During the summer of 2011, Simone worked with her collaborator, Lenore Grenoble from the University of Chicago, to document plant uses in southern Greenland (Qassiarsuk and Nanortalik) by interviewing community-recognized... Read more.

Marcus Welker talking to children

Marcus Welker, PhD Student, Ecology and Evolutionary Biology

Marcus Welker studies salmon and how they find their way home. Salmon are born in rivers, migrate to the ocean or lakes, and return again years later to the place they were born with incredible precision.

Specifically, Marcus is measuring amino acids in rivers that are believed to give each river a unique chemical fingerprint that salmon learn as juveniles, remember as adults, and use to discriminate their home streams. Marcus wants to know if these chemical fingerprints are unique to ever river and if they are... Read more.

Benjamin Walker

Benjamin Walker, PhD Student, Engineering Sciences

Ben Walker studies ways in which to conduct safe crevasse detection for sup¬ply traverse personnel through robotics research. Each year a heavy equipment resupply is conducted between Thule, NEEM and Summit Camp, Greenland, and this resupply must traverse heavily crevassed sections of the Greenland Ice Sheet to complete the job. Ben’s research is developing a robot and instrument combination that will automatically collect and interpret this data.

During his fieldwork season at Summit Camp in June of 2013, Ben increased the... Read more.

Christine Urbanowicz

Christine Urbanowicz, Ph.D. Student, Ecology and Evolutionary Biology

Christine Urbanowicz studies the pollinators and plant-pollinator interactions that are beneficial for flowing plants in Greenland’s tundra ecosystem. She is interested in how variation in plant density and temperature influence the number of pollinators that visit flowers and the number of fruits a plant produces. She is also collecting data on parasites of bumblebees in Greenland.

In 2013, Christine counted the numbers of insects visiting flowers in six sites around Kangerlussuaq, Greenland, that were... Read more.

Jessica Trout-Haney

Jessica Trout-Haney, Ph.D. Student, Ecology and Evolutionary Biology

Jess Trout-Haney studies how climate change affects high latitude aquatic ecosystems, specifically their physical, biochemical, and biological properties. She studies how differences in lake chemistry and morphometry of low-nutrient Arctic lakes affect the abundance of cyanobacteria and cyanotoxins in southwestern Greenland.

In the summer of 2013, Jess surveyed 19 lakes of varying size and depth between Kangerlussuaq and the Greenland Ice Sheet in southwestern Greenland. She ran sonar transects across each... Read more.

Ruth Heindel

Ruth Heindel, Ph.D. Student, Earth Sciences

Ruth Heindel studies soils, a valuable resource for Greenland that supports natural ecosystems and also agricultural activity in South Greenland. Specifically, she studies past and present wind-driven soil erosion, a process that threatens soil resources by removing soil and disturbing vegetation.

During the summers of 2012 and 2013, Ruth collected spatial data describing eroded areas in the Kangerlussuaq region. Additionally, she measured lichen diameters in order to estimate past and present rates of soil erosion. In the spatial... Read more.

Lauren Culler

Lauren Culler, Ph.D., Ecology and Evolutionary Biology, Dickey Center Arctic Fellow and Outreach Coordinator

Climate change is causing temperatures to rise in the Arctic and Lauren is studying how these changes in temperature affect mosquito emergence from freshwater ponds.

During the summers of 2011 and 2012, Lauren Culler counted the number of mosquitoes in several ponds near Kangerlussuaq, Greenland, every few days and measured how many mosquitoes emerged from each pond. (See picture of individually wrapper mosquitoes.) She also used lab studies at Kangerlussuaq... Read more.
