[anecdotally, I have experienced this scuba diving in a drysuit in WA and BC, especially in freshwater, so it is wonderful to see some background]

A Crew Was Searching For Shipwrecks In Lake Michigan—But They Found Something Completely Different

“ • A survey of Lake Michigan located at least 40 large craters on the lakebed.
• Initial studies highlighted the spots as unknown shapes, but additional research revealed the craters are filled with marine life.
• Researchers expect to investigate further, seeing how these craters formed and if they’re really sinkholes…"

A sonar image of a few of the sinkholes found at the bottom of Lake Michigan. Earlier this month, scientists with the National Oceanic and Atmospheric Administration Great Lakes Environmental Research Laboratory confirmed that circular depressions discovered in 2022 were in fact sinkholes. More than 40 have been found roughly 14 miles southeast of Sheboygan in the Wisconsin Shipwreck Coast National Marine Sanctuary.

Purple-hued cyanobacterial mats cover much of the bottom of Lake Huron's Middle Island sinkhole. Discovered in 2010, Lake Huron's sinkholes have been a hotbed for research ever since. The finger-like forms are caused by gases bubbling up underneath the mat.
Researchers from the National Oceanic and Atmospheric Administration Great Lakes Environmental Research Laboratory prepare to deploy a remotely operated vehicle to explore the newly discovered sinkholes in the Wisconsin Shipwreck Coast National Marine Sanctuary. More than 40 sinkholes were discovered 14 miles southeast of Sheboygan in the sanctuary.

Sensing Remote Realms of the Deep #Ocean on Earth—and Beyond eos.org/features/sensing-remot

"A novel laser-equipped probe is collecting measurements of #DeepSea geochemical environments that once seemed impossible to gather, pointing the way toward future explorations of other ocean worlds... This instrument can quickly analyze the composition of seawater as well as of seafloor rocks, sediments, and organisms, gathering data as fast as the #ROV moves and allowing for efficient surveys of large areas."

A journey under ice, into video publishing in the fediverse and editing in @blender - all in one.

That time we flew a ROV under drifting sea ice to help oceanographers position an instrument. Above the ice it's not so serene - imagine wind, generators, and shouting instructions back and forth.

*updated to fix typos, make better titles and add a soundtrack

100-Year-Old Shipwreck Discovered 800 Feet Below Lake Superior [side-scan sonar / remote sensing / ROV]

“On October 11, 1923, a steel bulk freighter called the Huronton sank while making its way across Lake Superior. Now, a century later, researchers have located the shipwreck in an 800-foot-deep hole in the lake floor.
The Great Lakes Shipwreck Historical Society announced the find last week on the 100th anniversary of the ship’s sinking…
Researchers with the historical society discovered the Huronton’s wreckage in Lake Superior this summer. Aboard the R/V David Boyd, they were using side-scan sonar to systematically search for wrecks.."
