What Are They Doing?

This research project on the Greenland ice cap examined the air trapped in firn (old snow that has recrystallized into a more dense substance through the weight of the overlying snowpack) for clues to past climates. The unique characteristics of firn allow the sampling of large quantities of pre-industrial air to explore anthropogenic effects on the atmosphere. While in the field, the team conducted a variety of snow measurements; post-field analysis of the data enabled a better understanding of past climates and the impact of human activity on the Earth's atmosphere.

Where Are They?

The team traveled to Summit Station, located at the peak of the Greenland ice cap atop 3200 m of ice. Summit is a scientific research station sponsored by the National Science Foundation that supports a diversity of scientific research, including year-round measurements of air-snow interactions that provide crucial knowledge for interpreting data from deep ice cores drilled both at Summit and elsewhere.

After being at Summit on top of the ice sheet in Greenland where snow accumulates at a rate of 60-65 cm per year, I still wanted to see the edge of the ice sheet. The Russell Glacier is about 17 km from Kangerlussuaq. Some people hike the stretch, some ride bikes, but a few of us signed up with a…
We have a few days in Kangerlussuaq to explore and decided to hike all day around the Lake Ferguson area. Most of the team that worked with the ice cores went trekking for the day. The layers of schist with the garnets were a goal of the hike. But along the way was incredible evidence of…
It has been a quick three weeks and now it is time to get ready to leave here.  The Hercules LC130 will be here tomorrow to pick up the science cargo, personal gear and those who are leaving camp.  Others will be coming to take our place.  packing up the drill Today was a packing up and moving…
I have been taking my GPS where ever I go and Summit is no exception. I really do like to see where I am, especially when flying on airplanes. Only once did I have a flight within the US where I could access a GPS unit in the seat in front of me and that was awesome. So I just carry my own GPS…
I have been dressing in multiple layers from head to toe to keep warm. But on Saturday, June 2, the wind was low (not enough to turn the windmill), the sky was almost cloudless, and air pressure was rising. Our temperature reached 14F...a heat wave! Midmorning I went to my tent to shed clothing…
CIMS is an acronym for the Chemical Ionization Mass Spectrometer.  Dave Tanner from Georgia Tech knows this instrument inside out.  Ambient air enters the system under a controlled flow, taking samples every 3 seconds.  The gases are reacted with Sulfur hexaflorine (SF6-) which form ionized…

Greenland Snow Studies Resources

Overview

The journal assignment involves students in current science research. Through the teacher’s journals, they will learn about how the research teams work together, design their research, tools that are needed and how they live and work in an extreme environment.

Objective

Students will be able to:

Overview

Working in groups, students will use common materials to create layers of snow and ice representing thousands of years of stratification. Groups will exchange their ice layers and extract core samples to analyze them.

Objective

  1. Notice the phenomenon of stratification.

  2. Notice that layers can tell a story of change over time.

Live Event with Jo Dodds and the Photochemistry group at Summit (led by Jack Dibb)

Live from IPY! event with teacher Jo Dodds and the research team in Summit, Greenland. The focus of the event was about the various snow studies being conducted at Summit. Note about the archive: The WIMBA archive has some audio. We had technical difficulties mid-way through and the audio got disconnected.
