Three Days on Ice

January 25th, 2015

group

Dr. Lowell and a crew from the University of Cincinnati spent thee days with us on the ice at Browns Lake Bog. The objectives were to take a series of long cores from the ice platform at the bog and, in the big lake,  to take a short surface core that the Wooster Geomorphology class will study. In addition we installed a series of four nested monitoring wells in the sediments around the lake.coring_theoryThe coring crew taking the deep core – about 24 meters in two meters of water depth.

The sediment-water interface on TV – note the screen on the ice that helped guide the coring process to be sure the actual sediment-water interface was captured.

Subsampling the upper core to be sure the modern sediments at the interface were in the bag.

    Great images! Glad no one fell through the ice, or got frostbite. You got the best weather just in time.

    The ice was 6 inches thick and temperatures just right in the mid-20s F with a dusting of snow for mood.
