Ever wondered what it actually looks like as samples are collected from the floor of Lake Michigan?  A science teacher from Elk Grove High School in Illinois got to the bottom of it for you.
When it came time to lower the multi-corer and hydraulic extruders, Quinn Loch strapped on a GoPro video camera to go for the 158-meter ride to the bottom.
 
Loch, along with 14 other educators, is working with 4 scientists as a part of the Shipboard Science Workshop aboard the U.S. EPA R/V Lake Guardian.
 
The cores will be used to study dissolved oxygen and phosphorous levels in the water just above the cores.
 
The educators and scientists stand on the dock in Manitowoc, Wis.
Be sure to follow the educators on twitter at #lakeguardian and on the Teacher Features page on the CGLL website
 

They will continue tweeting and blogging until the trip’s conclusion on July 18.
