Saturday at Au Sable Institute

In the morning after breakfast the group got together and Dr. Paris & Jon Becker explained to the class how the temperature & oxygen readings would be gathered.

We headed out to several areas on the lake and used an auger to cut holes through the ice. They proceeded to lower the temperature & oxygen props 1 meter at a time and collected data along the way. Three measurements were taken, one along the shore at 20ft, at a depth of 45ft & then out toward the middle of the lake at 65ft.

One would think we are ice fishing but we are collecting scientific data.

The majority of the day was spent outside, although the sun was out it was cold with the high of 18 degrees. The wind out on the lake did not help in any way.

In the afternoon fter collecting the data, Jon Becker input it into the computer and graphed it out, explaining the students and showing them how it was done.

In the evening after dinner and a small break, the students got back together and Dr. Paris discussed the results of the data collected. He showed them with the data collected how temperature increases with depth while oxygen decreases with depth.

Friday at Au Sable Institute

After a morning at the lodge at Au Sable checking the internet, some studying, quiz taking and a general easy morning, the class went out to download and retrieve data from the data loggers they put in place the evening before.

In the afternoon we snowshoed in the Hartwick State Park on the Au Sable River Foot Trail. As we walked along the trail, we observed the variety of trees along with the tall red & white pines. Dave Mahan from Au Sable Institute pointed out animal tracks and the class tried to identify them.

We drove into Grayling and ate at Dawson & Stevens Classic 50’s Diner … it was very good!

In the evening the class got back together to discuss what they are going to do Saturday. They discussed temperature relative to ice and what they’ll expect to find when they cut a hole in the ice on the lake.

Thursday at Au Sable Institute

We left campus around 8:15am and stopped for lunch & gas just north of Ann Arbor which was just about halfway to Au Sable Institute. We arrived at Au Sable safely around 4:30pm. As we arrived at the entrance to Au Sable we took a group picture.

We had some time to unpack before getting back together.
John Becker & Dr. Paris spent some time identifying & programing the six data loggers the class will be using to collect data.

As we started to lose daylight, the class dug a snow pit to set the data loggers at regular intervals up to 3 meters. The data loggers will be taking the temperature of the snow pack & the air above it every 30 minutes for 48 hrs.

We ordered pizza at nearby Carefree Cove (an all in one pizza shop, grocery store, gas station) and took it back to the house to eat. After eating, Dr. Paris had a short time with the students preparing them for some of the things they would be observing the next several days. He discussed the layers of snow & snowflakes that break down and refreeze.

Karen, one of the girls in the class brought her guitar and we closed out the evening with singing. It was a nice way to close out a long day.
