Hello Amy Clapp,

My name is Christopher Jones and I go to Whatcom Day Academy middle school. I have just completed 6th grade and I am 12 years old.

I was wondering what specifically would you be looking at in the rivers? What about the water will you be exploring?

I hope that you have fun and learn many new things while on your expidition!

Best Wishes,
Christopher Jones

Dear Christopher,
Thanks for your email. You have asked some great questions. First, specifically, when we are on the rivers we are going to be getting lots of different things. We will be testing to see how much dissolved oxygen, trace metals, dissolved carbon, organic matter (matter of parts of plants and animals), nitrate and pH as well as many other different parts of the water.

Basically, by analyzing the water, scientists will get two major pieces of information. First, they will find out information about what is going on in the Arctic Ocean Watershed (which is all the land that has water that eventually makes it to the Arctic Ocean). The water, as it passes through the watershed, picks up elements in the land, so by studying the water, scientists can find out about the land--pretty neat. However, the second important thing that the scientists will be able to determine from studying the water is that they will be able to figure out how the water in each of the 6 major rivers that flow into the Arctic Ocean are different from each other. Then, when they have figured out the unique "fingerprint" of the water they will be able to trace the water as it flows into the Arctic Ocean. Scientists are interested in doing this because if there is more water from these rivers flowing to certain parts of the Arctic Ocean, it may change some of the ocean circulation patterns that affect world wide weather. So, these samples may end up helping connect some of the major pieces of the "Global Warming" puzzle. Tomorrow we will be going out and doing our first set of samples on the Mackenzie River. I will write more about it and post the information in the Teacher's Journal which you can find at:

Then click on the project called Fresh Water in Arctic Rivers and teacher's journal. I will also be posting your question in the section called Ask the Teacher or the Scientist so in case other students have the same question, they will be able to find out the information you were interested in too!

Thanks for the great question. If you have any other questions about the project, feel free to get in touch again,
Amy
