Today our team met with the other REU internship team whom were working in the Bahamas, and as a group traveled to the Blue Heron on Lake Superior. The Blue Heron being a research vessel owned by the University of Minnesota Duluth. We boarded the ship and left the dock only to remain in the harbor all day because of poor weather conditions in the main channels of the Lake. Aboard the Blue Heron the crew pulled out various equipment and gave them trial runs to show us their effects. We used a sonar machine, a machine that takes four sediment cores at once as well as an incredibly long and durable coring device that geologists use to core in very deep lakes ,such as Superior, and the ocean as well. The crew then described the information that the machines relayed and dissected many of the cores. And after lunch we bounced to return to the Duluth campus.
