Teachers work on Lake Guardian

The Lake Guardian picked up 15 teachers here a week ago so they could get first hand experience working with and learning from several scientists on board. They took samples from the bottom of the lake and analyzed, and some times counted, what they found. They wanted to see who was eating who – not a food chain but more like a food web since many critters have great variety in their diet. They were looking for Diporeia, 2 mm long shrimp-like critters that, unfortunately for them, live at the bottom of the web. Since Diporeia get eaten by everybody else, including the big fish, they figure where they find Diporeia, they will find fish. They went to one hot Diporeia spot and found a lot of fishermen. It turns out fishermen also have a way of finding where the fish are without counting Diporeia. Later, they welcomed a ‘fish expert’ on board who brought with her a bunch of fish stomachs to dissect; that’s where they find the answer to the question, who is eating who. Above, 3 of the 15 teachers stopped to talk on Monday morning before heading home. At the left is Stephanie Erickson who teaches 7th and 8th graders in St. Paul, Bo DeRemee teaches 9th grade physical science, biology and physics in Ely and Robert Tonte lives in Roseville, Michigan and teaches science to 7th and 8th graders.

New to the crew

“How can I get a job on a ship” is a question I am often asked. I now have the answer! Pictured are 3 marine techs from the Lake Guardian, a research vessel operated by the EPA. It is here to host a 7-day Lake Superior cruise for 4th through 10th grade teachers that will leave on Tuesday, July 7th. The ship has been at the DECC but will move over to the Corps of Engineers dock while the Denis Sullivan and Clelia II are in town. Pictured above are 3 recently hired crew members on the Lake Guardian – from the left, Johna Winters, Steve Delworth and Meridith Berghauer. They are marine techs and assist visiting scientists, and next week teachers, in using the scientific equipment on board the ship. All three independently found their job within the last year on Craig’s List, the online classified section. They of course had to be qualified and then apply for the job and get accepted, but they found their jobs on Craig’s List. Johna and Meridith both have Bachelor of Science degrees while Steve had extensive experience in the Navy. Before getting her job on the Lake Guardian, Meridith worked for 3 years on the Denis Sullivan, the tall ship now in port. Photo taken on July 02, 2009

Lake Guardian does EPA work

The Lake Guardian arrived in Duluth on Monday for the second time this year. The EPA operated vessel is on the second of the two Great Lakes water sampling surveys it takes each year. It visits each of the 5 great lakes on each tour. It has only the southern shore of Lake Superior to go to complete this second tour.

The Lake Guardian departed Duluth last year on April 25 (above), with ice still in the harbor. The EPA operated vessel is on the first of its two Great Lakes water sampling surveys she takes each year. It can support up to 27 scientists on board performing numerous scientific investigations relating to water quality.
