Researchers discover a massive Lake Superior shipwreck

Historians estimate only 1% of shipwrecks have been discovered

The oldest known shipwreck dates to around 2,700–2,300 BCE, but evidence suggests humans started open-ocean sailing at least 50,000 years ago. Many have completely deteriorated but artifacts aboard the vessels remain, while many lack historical records of the event or location.

Mapping Michigan's shipwrecks

For centuries, the Great Lakes have provided vital access to the Midwest from the Atlantic Ocean, allowing the establishment of key trading outposts and ultimately the growth of major cities in the region. An estimated 6,000 vessels were lost on the Great Lakes with approximately 1,500 of these ships located in Michigan waters. Explore the deadly legacy of the region with resources pulled together by the Michigan History Center.

A new scan of the Titanic reveals details about its final hours

Using over 700,000 images captured by underwater robots, researchers created a highly detailed 3D "digital twin" of the Titanic. The analysis gives us new insights into the life of the ship that lays 3,800m down in the icy waters of the Atlantic. Emerging details from close-up images, such as a smashed porthole likely caused by the iceberg, match the eye-witness accounts of what happened. Read for more insights into the devastating wreck.

What revisiting a 1979 experiment reveals about ecosystem recovery after deep-sea mining

A 2023 study co-led by the National Oceanography Centre and the Natural History Museum, London, found that tracks made by the mining vehicle remained largely unchanged since 1979. Small animals, such as amoeba-like xenophyophore, were seen in the cleared areas, but sightings of larger animals known to live in the region were much rarer. (Some readers may experience a paywall.)

In 1820, a sperm whale sank a ship and inspired 'Moby-Dick'

The Essex's crew hoped to capture sperm oil, a lucrative material found in the heads of sperm whales. However, a whale charged and crashed into the ship. Survivors of the attack drifted at sea for months, and many experienced starvation, dehydration, and cannibalism. The ordeal inspired author Herman Melville.

The bison with mystery origins on California's Santa Catalina Island

Bison roam the 75 square-mile channel island of Santa Catalina about 25 miles south of Los Angeles in the Pacific. It's not clear exactly how they got there, but one theory says 14 of them were dropped off as part of a Hollywood film production. Generally beloved by the locals and vacationers, their numbers ballooned to nearly 600 but dwindled amid resource scarcity. What now? See the state of conservation efforts here.
