Graduate student Justin Stroup drills into a boulder near Quelccaya
Ice Cap in Peru. He uses cosmogenic nuclide dating to determine
when the boulder, and corresponding moraine, was exposed by a
previous extent of the ice cap (June 2010).

Graduate student Justin Stroup holds a short sediment core from a lake
in the Cusco region of Peru. This core, along with 16 others from lakes
around southern Peru, are being used to calibrate proxies for past
environmental conditions in the Peruvian Andes (June 2011).

Tilapia are transferred from their indoor tanks to outdoor tanks at Dartmouth's
Organic Farm, managed by Scott Stokoe (top right). The fish are being used in
sustainable aquaculture research being conducted by Prof. Anne Kapuscinski,
chair of the Environmental Studies Program. George Thorman '11, an
environmental studies research assistant, led the effort with assistance from
Molly Grear '11, Thayer '12, and Tasneem Khalid '12 (June 2012).

This summer 10 Dartmouth students will tour the nation on the Big
Green Bus to build enthusiasm for community involvement through
environmental action. This is the 8th year a completely student run
initiative hits the road to travel 12,000 miles across 24 states on a
reused, veggie-powered Greyhound bus (June 2012).

A research rocket was launched on February 18, 2012 high into the sky
over Alaska, into the Aurora Borealis. Professor Kristina Lynch and
others are collecting data on the nature of the aurora in relation to the
planet's environment and seek to understand the Aurora Borealis's mix
of electrically charged particles.

Morgan Matthews '15 using a small telescope to observe nearby old stars at
Dartmouth's MDM observatory in Kitt Peak, Arizona (March 2012). The stars
observed by Morgan were part of Professor Brian Chaboyer's Hubble Space
Telescope program to determine the ages of the oldest stars in our galaxy. In the
background is the 2.4meter telescope which was being used at the same time to
observe much fainter, more distant old stars.

A cold April morning found members of the Lynch Rocket Lab at the Mt.
Washington Regional Airport near Whitefield, NH. They were preparing to
conduct test balloon launches of the GreenCube and another vehicle known as
ALTAIR—Airborne Laser for Telescopic Atmospheric Interference Reduction—a
project being built for Harvard's dark energy research (April 2012).

Observational astronomer Robert Fesen set up a telescope and instructed curious
students and community members in a safe method of viewing the transit of
Venus, as the planet passed directly between the earth and sun for the last time
until the year 2117. Viewers got a quick look at the phenomenon until clouds
obscured the rare solar display (June 2012).
