Welcome to Freeze up data for Lake Marmo at the Morton Arboretum

Welcome to

Several students showed up on December 10, 2008 at the Morton Arboretum to collect our GLOBE weekly atmospheric data. After examining the temperature data for the week, Shruti suggested that we check Lake Marmo for freeze up. I didn't think it would have ice this soon, but I went over there and she was right. Lake Marmo had a thin sheet of ice that was covering 80% of the lake.

Lake Marmo is located a short distance from our Weather Station in the Morton Arboretum. We took 3 pictures of the lake from the site located at the red arrow and then we took 3 pictures of the lake from the site located at the yellow arrow.

This is view "C" looking Southwest on November 22, 2008

This is view "D" looking West, Northwest on November 22

This is view "E" looking northwest on November 22, 2008

This is view "F" looking Northeast on November 22, 2008

Students recorded the min/max temperatures of the air and soil from the last 6 days.

Then they took the surface temperatures using the IRT (Infrared thermometer)

This is view "A" looking Southeast on November 29, 2008. Lake Marmo was 100% frozen from shore to shore.

This is view "B" looking South on November 29, 2008.

This is view "A" looking Southeast on December 31, 2008. We had a warm spell after Christmas with a lot of rain.

This is view "B" looking South on December 31, 2008. Lake Marmo was no longer frozen from shore to shore.

This is view "A" looking Southeast on January 7, 2009. Lake Marmo was frozen from shore to shore.

This is view "B" looking South on January 7, 2009. The lake and the shore was covered with a fresh coating of snow.

This is view "C" looking Southwest on January 7, 2009.

This is view "D" looking West, Northwest on January 7, 2009.

This is view "E" looking northwest on January 7, 2009.

This is view "F" looking Northeast on January 7, 2009.

On January 10, 2009 we had 18.5cm of new snow. Thanks to Jake's Mom for bringing his friend Michael and him to the Arboretum.

2 students from Highlands School showed up to collect GLOBE Atmospheric Data.

We tried to get to Lake Marmo, but the road was closed.

I was able to take a picture of this Cardinal in my back yard.

Our Frost Tube showed that the frost has extended to 11 cm below the surface.

Lake Marmo melted 2 weeks sooner than last year, even though we had a colder winter.

My hypothesis is that we had much more snow this winter to insulate the ice. We then had over 10 centimeters of rain in early March.
