NOAA's Wisconsin Shipwreck Coast National Marine Sanctuary

NOAA's Wisconsin Shipwreck Coast National Marine Sanctuary WSCNMS provides stewardship for our national maritime heritage in Lake Michigan

Designated in 2021, Wisconsin Shipwreck Coast National Marine Sanctuary provides stewardship for our nation's maritime heritage in Lake Michigan. Co-managed by NOAA and the state of Wisconsin, the sanctuary expands on the state's 30-year management of these historic sites, bringing new opportunities for research, resource protection, and education. In partnership with local communities, the sanctu

ary provides a national stage for promoting recreation and heritage tourism. The 36 historic shipwreck sites within the sanctuary represent vessels that played a central role in building the nation between the 1830s and 1930s. Twenty-seven are listed on the National Register of Historic Places and research suggests that another 60 shipwrecks may yet to be discovered.

Look at all those divers! ⚓🌊

Over the last week and a half, a team of tech divers from the NOAA Dive Program have been diving on deep water shipwreck sites in Wisconsin Shipwreck Coast National Marine Sanctuary to document them using photogrammetry. Photogrammetry is a great tool for archaeologists and divers to use to help document, study, and monitor shipwrecks efficiently, by using underwater photography to create a scaled 3D model of the site. These models help the sanctuary monitor the shipwrecks and continue to study them over time.

While here, the team of divers have been assisting sanctuary staff with documenting marine debris found underwater on shipwreck sites. This includes fishing lines, old mooring lines, and other debris. This is part of a larger effort to document and remove marine debris throughout all three sanctuaries in the Great Lakes.

Stay tuned to hear more about photogrammetry and project progress!

Welcome back to another ! Today we are featuring Wisconsin’s oldest known shipwreck, the schooner GALLINIPPER!

GALLINIPPER was originally built in 1833 as the two-masted schooner NANCY DOUSMAN in Black River, Ohio for Michael Dousman, of the well-known Wisconsin Dousman family. The vessel was named for Michael Dousman’s daughter, Nancy. The vessel operated out of Milwaukee, carrying passengers, trade goods, furs, and other freight between eastern ports and Milwaukee until 1840, when Michael Dousman sold his share in the vessel.

In 1846, the vessel was rebuilt and lengthened in Milwaukee to increase its cargo carrying capacity, and relaunched with the name GALLINIPPER. Although the vessel was lengthened by 26 feet, it was not widened, making it prone to heeling over in waves when the vessel was riding light. After its relaunch, GALLINIPPER operated in the wheat and lumber trades, carrying cargos on Lake Michigan and Lake Huron. The vessel sailed for another five years, changing owners a few times, until July 1851.

On July 7, 1851, while heading north to Bay du Noc, Michigan for a cargo of lumber, GALLINIPPER was hit by a sudden squall north of Sheboygan. Heavy waves caused the light vessel to capsize, but it was able to right itself initially, however, the wind and waves continued to increase, eventually pushing the vessel over a second time. This time GALLINIPPER was unable to right itself and it began to fill with water and founder. Nine crewmembers were aboard at the time, all of which were saved by a passing vessel.

Today, GALLINIPPER sits upright in 210 ft of water, 9.5 miles east of Cleveland, Wisconsin. In the early 1990s, the vessel’s foremast was detached and pulled to the surface by a snagged fishing net and is now on display at Rogers Street Fishing Village in Two Rivers. The vessel’s mainmast still remains on the wreck, pitched forward at an angle over the vessel’s bow. Other than a missing cargo hatch, the rest of the vessel is in remarkable condition due to the cold, deep, dark water. GALLINIPPER was documented by maritime archaeologists and volunteers from the Wisconsin Historical Society in 2009, and was listed on the National Register of Historic Places in 2010. In Aug 2024, a Wisconsin Shipwreck Coast National Marine Sanctuary mooring buoy was installed at GALLINIPPER’s wreck site!

Field season is officially well underway at Wisconsin Shipwreck Coast National Marine Sanctuary!

This week, a team of tech divers from the NOAA Diving Program arrived in the sanctuary to assist with a project documenting shipwrecks in over 150 feet of water using photogrammetry. Photogrammetry is a great tool for archaeologists and divers to use to help document, study, and monitor shipwrecks efficiently, allowing divers to document sites by taking hundreds (and sometimes thousands) of still photos, which are used to produce a 3D model of the site.

While here, the team of divers has also been assisting sanctuary staff with installing the remaining shipwreck mooring buoys!

Stay tuned to hear more about photogrammetry and project progress in the coming weeks! 🛟

Hello and welcome to another ! This week we are featuring the fishing tug HENRY GUST!

HENRY GUST was built as a fish tug in 1893 at the Milwaukee Shipyard Company (which soon became Wolf & Davidson, and later the Milwaukee Drydock Company) for a fisherman who lived on Jones Island, named Henry Gust. The vessel was originally outfit with a 180hp engine built at Vulcan Iron Works in Milwaukee. The vessel was owned by multiple owners over the years, primarily used as a fish tug. In 1918, HENRY GUST underwent an overhaul at Sturgeon Bay, and continued to be used for fishing by its new owners.

In 1929, the vessel was shortened to 65 feet to avoid having to have an engineer aboard at all times. After this, the vessel continued to operate in the local fishing industry, however, by 1935, the aging vessel was beginning to leak more frequently, and the cost of maintaining the vessel continued to grow. Later that year, HENRY GUST was abandoned at a small dock in Milwaukee and was sold to the Alfred Muchin Company (salvage company) who salvaged the vessel’s metal components. As the vessel sat at the dock, it began to leak more and couldn’t stay afloat without constant pumping.

To prevent HENRY GUST from foundering at the dock, the Alfred Muchin Company decided to abandon the vessel in Lake Michigan. HENRY GUST was towed out a few miles into Lake Michigan in August 1935 (90 years ago next month), and set on fire, however, the vessel remained floating after burning to the waterline. To sink the vessel, the Two Rivers Coast Guard rammed the side of HENRY GUST, finally causing it to sink.

Today, HENRY GUST sits broken, on a heavy list to port, in 80 feet of water. Although the vessel was burned to the waterline, much of the vessel’s hull remains on the site, including its large boiler, laying on its side. The vessel’s rounded stern also stands out, as well as the entire lower portion of the hull. Only the port side section of the bow remains visible, however, many more hull features likely lie beneath the sand nearby.

In 2022 and 2023, divers and researchers from the Wisconsin Shipwreck Coast National Marine Sanctuary and other partners visited HENRY GUST and collected photogrammetry data for 3D models of the site for monitoring. These two models are a start in the ongoing monitoring and preservation projects being conducted on many of the wreck sites within the sanctuary.

Last week, the first data buoy in Wisconsin Shipwreck Coast National Marine Sanctuary was installed for the season!

On Wednesday, sanctuary staff were out on Lake Michigan installing the Port Washington spotter buoy with the help of Mike Loescher, a volunteer from the Sanctuary Advisory Council, and his boat!

These small spotter buoys are designed and built by Michigan Technological University and maintained by the Wisconsin Shipwreck Coast National Marine Sanctuary, and they are a part of the Great Lakes Observing System (GLOS). The buoys collect real-time wave data along with lake temperature data at four temperature nodes down to 110 feet deep, helping boaters, fishermen, and divers safely and effectively enjoy what Lake Michigan has to offer!

The large data buoy (located off Sheboygan) and second spotter buoy (located north of Rawley Point) will be installed in the coming weeks!

You can check out the real-time data being transmitted from these buoys at the National Buoy Data Center's page: https://www.ndbc.noaa.gov/

Meet the new Wisconsin Shipwreck Coast National Marine Sanctuary research vessel, R3601 (SAM GRAY)!

This vessel is new to the Great Lakes Environmental Research Laboratory and the Wisconsin Shipwreck Coast National Marine Sanctuary teams, but it has worked in sanctuaries for many years. SAM GRAY comes to Wisconsin from Gray's Reef National Marine Sanctuary where it was one of their diving platforms. This summer, it will be a diving and research platform here in Wisconsin!

The vessel is 36 feet long and features a small forward cabin and large aft deck: perfect for diving, buoy deployments, research projects, and more! Stay tuned to see R3601 in action this field season!

Hello everyone and welcome back to another ! This week, we are featuring the small lakeshoring schooner BYRON!

BYRON was built for the Burmeister family of Manitowoc, Wisconsin around 1849 to operate in the lakeshoring trade on Lake Michigan, and served many of the small farms and communities along the lake’s shores. Measuring only 36 feet in length, BYRON could visit small, unimproved ports along Wisconsin’s coastline, transporting goods and cargo between these smaller communities and larger cities like Chicago and Milwaukee. Vessels like BYRON were an instrumental part of Wisconsin’s agricultural development and allowed goods to be transported from small hinterland farms to larger markets in places like Milwaukee.

BYRON spent much of its 18-year-long career carrying lumber and other bulk cargoes along Lake Michigan’s western shoreline, between Manistee, Michigan and Milwaukee. On the night of May 8, 1867, while sailing just south of Sheboygan, BYRON collided with the schooner CANTON after the larger vessel made an unexpected course change, sailing straight into BYRON’s hull. The vessel sank in only 15 minutes, but luckily, the captain, crew, and sole passenger were able to jump aboard CANTON before BYRON sank beneath the lake’s surface.

Today, the vessel sits in 135 feet of water, 12 miles south of Sheboygan with its hull sitting upright on a slight list to port. The vessel’s masts and rigging no longer remain on site, but features of the vessel’s hull can clearly be seen. Reports indicate that when the vessel was located, much of its cargo remained inside, however, today, the hold is empty. The wreck site was recorded by maritime archaeologists at the Wisconsin Historical Society, and the vessel was listed on the National Register of Historic Places in 2009. In 2023, divers and archaeologists with the Wisconsin Shipwreck Coast National Marine Sanctuary revisited BYRON to capture updated imagery and create a 3D model of the site!

Although BYRON is a small vessel, it’s a unique site to visit, and as one of the only examples of small coastal schooners in existence, BYRON is an incredibly unique resource that helps tell the story of Wisconsin's Lake Michigan coast.
