DULUTH, MN (Northland's NewsCenter) - The Duluth Environmental Protection Agency will be doing a study on Lake Superior's micro organisms.

For two weeks the EPA will use the Lake Guardian ship to survey plankton and similar tiny organisms from various areas of the lake.

Researchers will also use an underwater, remote-control camera to look at the lake bottom.

A marine technician on board the ship says the lower food web organisms are very important to the overall ecosystem so it's essential to monitor their health.

"They'll be collecting benthic samples and plankton samples as well as water chemistry, and they'll be also filtering for sediment," said Johna Winters, a marine technician on board the ship.

The marine technician says the Duluth EPA did a similar study five years ago, so they will be able to compare the information.
