|The early bird gets the worm, or today, the Blue Heron will be out on the lake getting rare water samples. Owned and operated by the Large Lakes Observatory at UMD, scientists aboard the Blue Heron collect water, sediment and nutrient samples all year long but rarely have an opportunity to do it in March. The Blue Heron is a small boat and there is usually too much ice in March. But not this year. Joined by scientists from the University of Minnesota, they should be departing under the Lift Bridge this morning around 7 am and returning around 6 pm tonight.
