Purvis recently wrapped up scrapping the laker Mississagi.

On June 8, 2024, the Michipicoten suffered hull damage while traveling near Isle Royale in Lake Superior. The ship’s crew reported hearing a loud bang while the vessel was in deep water. The ship began taking on water, and at one point reached a 15-degree list. The crew was able to issue a distress call and start pumps that alleviated the list to five degrees. The distress call was met by the MV Edwin H. Gott, which waited with Michipicoten until the arrival of the U.S. Coast Guard. Michipicoten sailed for Thunder Bay, ON, under her own power with escorts from the U.S. and Canadian Coast Guard. While in port, divers inspected the hull and determined the likely cause may have been metal fatigue. Divers discovered a nearly four-meter (13 foot) crack in the hull. The divers placed a temporary patch on the crack.

On June 20, 2024, Michipicoten arrived at Superior from Thunder Bay under her own power, escorted by the tugboat Helen H, bound for Fraser Shipyards for inspection and repair, however Transport Canada never approved her return to service after repairs. In 2026, Michipicoten was acquired by Algoma Central Corp.

Lake Superior waves crash ashore west of Munising, MI, Thursday, [Roger LeLievre]

The National Weather Service issued gale warnings for most of Lake Superior Thursday, with northerly winds of 35 to 45 knots expected across the lake. The strongest winds will occur over the central waters, with wave heights building to 15 feet. Along the shoreline, wind gusts between 35 and 45 mph will be common Thursday morning, gradually diminishing from west to east through Friday morning.

Several vessels on Lake Superior were hugging the north shore. Kaye E Barker was tucked in L’Anse Bay at the southern end of the Keweenaw Peninsula. Mesabi Miner was anchored in Goulais Bay on the Canadian side above the locks. Ebroborg, Lee A. Tregurtha and American Mariner were on the hook above DeTour. James R. Barker was anchored north of Mackinac Island while American Spirit was stopped west of the Mackinac Bridge.

A man was swept into Lake Superior from the shore at Marquette’s Presque Isle Park on Thursday, police said, and is still missing.

The R/V Neil Armstrong, which departed its home port of Woods Hole, Massachusetts, on Wednesday, October 28,  is expected to arrive in Duluth on November 9 after passing through the Welland Canal on Thursday.

The University of Minnesota Duluth is working with the research vessel to detect and observe neutrino interactions in Lake Superior. Neutrinos are the most abundant particles that have mass in the universe, and they pass through everything. They are very difficult to detect, so studying them requires special instruments.

A beam of neutrinos is already positioned by Fermilab that runs through Lake Vermilion and Lake Superior. The Neil Armstrong will deploy sensor frames on the lakebed of Lake Superior several miles offshore near Two Harbors. These frames are 30 feet tall and weigh

8,000 pounds each. When it’s dark at night, they will be able to detect neutrino particle beams underwater. They anticipate detecting several NuMI beam neutrinos per day during the experiments.

The neutrino detectors will be removed as lake conditions allow in the spring or early summer of 2027. You can read more about the project in depth from the University of Minnesota Duluth.

Six years ago, the U.S. Navy announced plans to construct two ships in a new Ocean Class of research vessels and in 2010, awarded WHOI the no-cost lease to operate the first of the ships. Two years later, the Navy announced the first ship would be named Neil Armstrong and its sister ship, to be operated by Scripps Institution of Oceanography, would be named Sally Ride. The 238-ft. Neil Armstrong is the newest ship in the U.S. academic fleet, and one of just seven in that fleet capable of accessing all but ice-covered areas of the global ocean.

The R/V Neil Armstrong is the most technologically advanced ship in the U.S. academic fleet. The ship contains two multi-beam echo sounders designed to operate at different depths, making Neil Armstrong and, when completed, Sally Ride, the only ships in the UNOLS fleet equipped to conduct high-resolution seafloor surveys almost anywhere the ship can sail.

The ship’s three acoustic Doppler current profilers (ADCPs) can scan the water column at different frequencies to reveal the invisible structure of water at varying depths and resolutions, and a multi-beam, multi-frequency echosounder, the EK-80, can not only detect the presence and abundance of marine life beneath the ship, but also offers the potential to differentiate among species of fish and other marine life hidden beneath the surface.

From an engineering standpoint, as well, the ship is state-of-the-art. In addition to clean-burning diesel-electric generators, variable-frequency DC propulsion means less wear-and-tear on critical components and higher efficiency. The new ship’s integrated controls provide access to virtually every critical system, from propulsion and navigation to electrical load to heating and air conditioning to ballast, on touch screens in the engine room and bridge. The navigation system can be monitored and diagnosed from shore.

SAULT STE. MARIE, ON – Seaspan Shipyards has announced the award of Algoma Steel Inc. and Stigterstaal Canada as the primary steel plate suppliers for up to six multi-purpose icebreakers (MPI) for the Canadian Coast Guard. The new agreement, valued at about $182 million, establishes the supply of up to 24,000 metric tons of Canadian-made structural steel — 4,000 metric tons of steel plate per vessel — to support Seaspan’s construction of the CCG’s MPI vessels under Canada’s National Shipbuilding Strategy. This agreement is the result of strong collaboration between Seaspan, Algoma and Stigterstaal, building upon the companies’ strategic partnership established in 2025 to further strengthen Canada’s domestic steel and marine manufacturing industries.

Today’s announcement reflects the companies’ shared commitment to strengthening Canada’s defence industrial base and building resilient domestic supply chains capable of supporting Canada’s long-term sovereign shipbuilding and Arctic security objectives.

As part of the largest order of polar-class steel in the mill’s history — which includes Seaspan’s flagship heavy polar icebreaker, the future CCGS Imnaryuaq — Algoma will produce structural steel for the MPI program, one of the biggest shipbuilding initiatives ever undertaken for the Canadian Coast Guard with up to 16 vessels on Seaspan’s orderbook.

Leveraging Stigterstaal’s expertise in marine steel processing and distribution, and Algoma’s strong reputation for producing high-quality sustainable Canadian steel, the two companies are creating certainty and long-term value for Canada’s marine and defence industries.

Designed in Canada by Seaspan’s world-class icebreaker design team, the Canadian Coast Guard’s multi-purpose icebreakers will operate year-round in Canada’s most demanding Arctic and offshore environments. Measuring approximately 100 metres in length with a displacement of nearly 9,000 tonnes, the ships will accommodate a crew of 50 personnel and feature advanced diesel-electric propulsion with Polar Class 4 (PC4) icebreaking capability. The vessels will provide the Canadian Coast Guard with enhanced icebreaking, search and rescue, environmental response and maritime sovereignty capabilities while supporting Canada’s presence in the North. All MPIs will be built in Canada at Seaspan Shipyards in British Columbia, ensuring the future of Canadian maritime defence is built by Canadian workers with Canadian steel.

This partnership with Algoma and Stigterstaal aligns with Seaspan’s broader efforts to increase the use of Canadian-made materials in shipbuilding under the NSS and foster collaboration across the country’s industrial base. Through the NSS, Seaspan is delivering tangible industrial and regional benefits to the marine industry across Canada boasting a supply chain that includes more than 880 Canadian companies resulting in more than $3 billion in contracts.

Seaspan has built a highly skilled workforce in Canada with the skillset needed to weld steel thick enough to go through Arctic ice. Using Canadian materials, Seaspan is sharpening Canada’s strength at sea equipping the Canadian Coast Guard with the next generation of polar icebreakers to keep Canada’s coastlines protected.

TWO HARBORS, MN – An investigation is underway after a detached building that’s used as a gift shop for the Two Harbors Lighthouse went up in flames Monday evening. As of Tuesday morning, local authorities have yet to release information on the blaze, which likely broke out around 5:30 p.m. Officials with the Lake County Historical Society, which controls the lakeside property, told Northern News Now that no one was injured, but the damage to the building is significant.

“We were literally watching a piece of Lake County’s history go up in those flames,” Lake County Historical Society Vice President David Johnson said in an interview with the station.

It’s believed that the fire started in the breezeway between the gift shop and a connected structure, both of which are separate from the historic lighthouse. The Lake County Historical Society shared this statement: “We are incredibly grateful to the firefighters and first responders who have responded and are working to address the situation. Their time, dedication, and efforts are greatly appreciated.”

SAULT STE. MARIE, MI – Nearly 196,000 people visited the Soo Locks Visitor Center the six months it was open from May 1 to Oct. 31. The center is located inside the Soo Locks Canal Park off Portage Avenue. While this number is down about 39,000 from last year, U.S. Army Corps of Engineers Chief Park Ranger Michelle Briggs says the six-month season was still a success. Brigg’s staff of five park rangers were kept busy providing many services.

“Rangers administered the water safety pledge to 1,735 people as of Sept. 30. People who took the pledge, who promised to be safe around the water, received water safety goody bags. Rangers also provided more than twenty talks for scheduled tour groups and for all visitors during lulls between ships.

Through September, Briggs also stated volunteers at the Visitor Center contributed more than 700 hours of their time helping with special events, working on the flower beds and answering visitor questions in the observation platform. Many took advantage of the remarkable mild autumn weather Saturday and witnessed several freighters pass through the Soo Locks, but also had the opportunity one last time to experience the extensive amount of information inside the Visitor Center.

Park Rangers made themselves available to answer questions throughout the day with visitors able to check out many exhibits. Ed Cook, who is in his third year as a park ranger, was working the final day Saturday. Cook is a life-long Sault Ste. Marie resident and has always loved the freighters.

Before this current park ranger position, he owned a grocery store/meat market. While at that profession, he talked to a lot of people which prepared him to converse with the tens of thousands of visitors each year.

“I didn’t know as much as I thought I knew when I got a job here because there’s so much more to the Soo Locks than I ever realized. It’s amazing how often people tell me they came here with no expectations, it was just something to knock off their bucket list and when they come here and experience it, how it excited they are to learn about it and how amazed they are about how important the Soo Locks are,” Cook said.

While the Soo Locks Visitor Center is closed until May 1, 2027, Soo Locks Canal Park remains open all year round.

MUSKEGON, MI – After more than three months away from its home port, one of the most decorated American submarines of World War II has made its way back across Lake Michigan.

The journey marks the completion of the submarine’s first comprehensive dry dock preservation project since July 1954, a span of more than 72 years.

Unlike the wartime patrols that made it famous, Silversides is no longer capable of operating under its own power. The submarine was towed across Lake Michigan, much as it was when it departed Muskegon on July 13.

That departure was a memorable event for the hundreds of people who gathered along the Muskegon waterfront to watch the historic vessel leave its longtime berth.

A flotilla of recreational boats gathered along the Muskegon Channel as the submarine began its journey. The Muskegon County Sheriff’s Office provided an escort, complete with a ceremonial water salute, while boat horns sounded as Silversides slowly made its way into Lake Michigan.

The excursion vessel Aquastar, carrying more than 100 passengers, followed the convoy about two miles offshore, giving passengers an opportunity to watch as the submarine and its accompanying tugboats headed west toward Wisconsin.

It was an unusual sight on Lake Michigan: a World War II submarine underway more than eight decades after entering service.

The July voyage was handled by two tugboats operated by Basic Towing, Inc. of Escanaba: Nickelena and Erika Kobasic. The two tugs are handling its return as well.
