4 July 2011 Day 7: Real scientists!!! (Glacial deposits, fossils, and independent research projects)
Submitted by Christine (Denmark), Maria (USA), Sofie (Greenland), and Tina (Greenland)
We started our morning with an interesting presentation by two real life scientists, Laura Levy and Patrick Applegate. They talked about glacial history, landforms and how ice cap has moved. They also talked about how it is to be a scientist today and encouraged us to start our own research projects. We learned about the fossil formation and the difference between the different layers of sand structures left by the glaciers.
Today was also the day where we picked up our mountain bikes so now we have more freedom and it is easier to go to our sites and dinner. We road our bikes to location where Laura and Patrick gave us a better demonstration of their daily research and once more we looked for fossils.
In the afternoon we prepared our own research project and organized our schedule. We had to find out where to collect data and what we needed for our investigation. It was a big logistic project but we succeed and learned that there is a lot of work before going out into the field.
Now we are ready to go into the field, collect our data and proceed with our research

Student Research Groups: Devloping a research plan for days in field
sikorsuit (Greenlandic)- glacier
sermersuaq (Greenlandic)- inland ice
rouche moutonnee- bedrock that is smoothed on one side by glacier and broken off on other side (indicates ice movement direction)
erratic- boulder carried by, then dropped/left behind by glacier as ice melts and recedes
kettle lake-glacial lake formed by large pieces of glacier that broke off and was left behind as ice melted/receded
moraine- pile of glacial till left behind by glacier as it recedes
isostasy- elevation of Earth's surface is a balance between the weight of the lithosphere and the bouyancy of the asthenosphere
lichenometry- the study of using the size of lichens to determine the surface exposure of rocks
loess- very fine, wind blown sediment deposits
