HELLO FROM SUMMIT CAMP!!!

See, things up here aren’t as bad as you might think!!

Some of the chemicalsReleased by the snow Are harmful to ourEnvironment (like Nitric oxide (NO))…..

While still others thatForm in the snow are Helpful to our environment(like hydroxyl (OH)

Date of Experiment

This graph shows how quickly nitrate is being changed into Nitric oxide. You can definitely tell that when there was moreSunlight (Apr. 4th), it was happening much faster!!!

Knowledge and innovation are powerful forces for progress in the lives of people and nations. The leadership of the United States and its unsurpassed standard of living rest on the solid foundation of achievement in science and engineering. Investments in fundamental research and education have supported decades of U.S. global leadership in discovery, learning and innovation.

Although this is a complicated diagram, it shows the many waysWind influences the chemistry that is happening in the snow

You can really see how the temperatures made a dramatic jump up right about the time I got here!!!! (It must be my warm Personality)

This gives you an idea of how far we walk- sometimes several times a day!!!

The researchers here sometimes have to put up with some pretty nasty conditions, but sometimes it is the mostBeautiful place on earth to work!!

Don’t I look toasty?!?!?

Some of the people at camp sleep in Arctic ovens- unheated tentsWhile others stay in the comfort of The heated weatherport (large, heatedTent)

Researchers will be using what they learn at Summit to try and figure out how these chemicals affect the air and how all the pieces fit together.

All of the equipment here is highly specialized….

And VERYExpensive!!!

BYE GUYS!!!!

BE GOOD!!!
