All of this while US Coast Guard Sector Soo began Operation Taconite, their annual push to clear shipping channels of ice so lakers can get another 2 or 3 weeks before the season ends. For now, the Alder was assigned the western end of Lake Superior for their ice breaking operations. That seems logical but in others years, they were breaking ice in Lake Michigan and cutters like the Biscayne Bay came here to break up our ice. All pictures here courtesy of the Alder.|

Ice is one of the categories and since there does not seem to be much ice around, I thought I would highlight all the pages through the years about ice. You can click on the category pull down and see all 93 (94 now with this page) pages with lots of ice on them or see the list by clicking here.|

NORTHERN MICHIGAN — It appears spring is finally here and with the end to another brutal winter comes the end of another year of extensive Great Lakes ice coverage.
According to George Leshkevich, physical scientist at the National Oceanic and Atmospheric Administration (NOAA) Great Lakes Environmental Research Laboratory, total Great Lakes ice coverage peaked Feb. 28 at approximately 88.7 percent combined among the five lakes.
Though some of the lakes — Erie, Huron and Superior — approached almost complete ice cover, the total of 88.7 percent fell short of the ice coverage mark set last year on March 6, and approximately 6 percent short of the record set in 1979 at 94.7 percent.
“The way things are going now, we are looking at an earlier breakup and an earlier ice-off date (compared to 2014),” Leshkevich said. “Last year was extreme.”
According to statistics compiled by the Great Lakes Environmental Research Laboratory, out of all of the Great Lakes, Lake Erie reached the highest ice coverage percent at 98.09 percent on Feb. 18.
Lake Ontario also experienced its peak ice coverage Feb. 18, when 82.6 percent of the lake was covered in ice.
Coming in at No. 2 for highest total ice coverage was Lake Huron, recording an ice coverage of 96.28 percent on March 6.
Lakes Superior and Michigan both reached their maximum ice coverage Feb. 28, with Lake Michigan recording 72.8 percent ice coverage and Lake Superior 95.5 percent.
Since reaching those numbers, warmer temperatures and larger amounts of sunlight among other factors have began to break up the large quantities of ice.
“It is going down now,” Leshkevich said in regard to the melting ice. “Even if we get another cold snap, it would have to be really cold for really long to turn things around.”
Leshkevich said the ice coverage patterns this year are about normal, as the lower Great Lakes — Erie and Ontario — typically reach maximum ice coverage between the middle and end of February, while the upper Great Lakes — Michigan, Superior and Huron — usually reach peak ice coverage sometime during the first half of March.
Unless there is another cold spell, the ice cover should continue to melt as spring approaches, unlike 2014 when Leshkevich said some amount of ice cover remained on Lake Superior until June 6.
But with the unpredictable Michigan weather patterns, Leshkevich said anything is possible.
“Things could still turn around,” he said. “Cold weather could prolong (the ice cover).”

|Sometimes in the winter, the hardest thing for a boat to do is make a dock; even if the course thru the ice is not much of a problem. A 1,000 footer weighs a lot and can brush aside a lot of loose ice as it goes thru the harbor. Moving all 1,013 feet up against a dock is another story. Loose ice, easy to go thru in open water, compresses as the vessel moves closer to the dock; a tug is often needed to not only break up the ice but also flush the ice away from the dock, leaving room for the boat to move up against the dock and tie up. If the ice is not cleared, the vessel does not make the dock. Here, after coming under the Lift Bridge and moving up the harbor, the Paul R. Tregurtha points her bow to the dock, allowing a deck hand to drop down to the dock to secure the bow. The rest of the boat slowly closes toward the dock, carefully, and often with the help of a tug, pushing the loose ice out of the way. You can see the tug at the far right, moving out of the way after breaking up the ice. That was at 1 pm on Sunday, January 11, 2015. After taking on fuel at Calumet, she then moved over to Midwest Energy to load her last cargo of coal of the season. She left at 4:56 the next morning with 66,000 tons of coal for Detroit Edison. Another trip here was planned but has apparently been canceled, making this her last and 41st visit this season. Last year, without a late start due to ice, the Tregurtha was here 49 times.|
