Thanks to digitized archives, shipwreck hunters can now do in a day the research that once took them at least a week or two.

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.

A 292-foot Whaleback ship, Barge 129, was found in Lake Superior 120 years after a storm sank it, the Great Lakes Shipwreck Historical Society said.

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.

From The Portland—known as New England's "Titanic"—to the Civil War's USS Monitor, this archive from the National Oceanic and Atmospheric Administration provides overviews of some of the most well-known shipwrecks in US history.

Crew aboard the Exploration Vessel Nautilus discvered a “yellow brick road” that looks it leads to Atlantis. Climage change may affect future ocean studies.

Operated by the British Antarctic Survey, the RRS Sir David Attenborough and its onboard tools and laboratories have investigated the biogeochemical cycles of the Southern Ocean, the stability of Greenland's ice shelves, and the impact of climate change on marine ecosystems. One of the ship's autonomous underwater vehicles was named Boaty McBoatface based on the results of a naming poll from the Natural Environment Research Council.

When the USS Oklahoma capsized amid the attacks, hundreds of sailors were buried within the ship's hull. Officials have used advances in forensic science to analyze DNA and dental evidence to help identify nearly 400 sailors decades after the fact.

Divers in the Santa Barbara channel innovated a more efficient type of diving helmet in the 1960s that used helium to allow for longer, deeper excursions for oil surveying, abalone collecting, and more. These innovators have since set the standard worldwide for military and industrial diving.

Archaeologists are increasingly relying on dogs to help find decaying bodies at burial sites, some of them up to thousands of years old. This is helping archaeologists to detect past remains without ever touching a shovel, which means there's less...

By studying extreme environments in Earth's hadal zone—the deepest part of the ocean —NASA tests technologies, probes life under crushing pressure, and gathers clues about potential oceans and possible life on worlds like Europa and Enceladus.

Archaeological teams now have another item to pack with their trowels: Lasers. Researchers' approach to unsurveyed land has been transformed by light detection and ranging technology. LiDAR has helped archaeologists break new ground and uncover...

Centuries of maps include islands and isles that appear to only exist on atlases. This article explores the discovery and "undiscovery" of such landscapes, which still persist despite modern technology. As recently as 2012, Google Maps showed an...

While searching for World War II wreckage near Cape Canaveral, Florida, for a documentary, divers discovered debris on the seafloor that NASA later confirmed to be a piece of Space Shuttle Challenger wreckage. The piece is at least 15-by-15 feet in size and partially buried under sand.

The year’s most exciting discoveries include a Viking “piggy bank,” a lost Native American settlement and a secret passageway hidden behind a bookshelf

Lidar is a cutting-edge tool using lasers from an aircraft to map the elevations of huge swaths of land across the world. This technology has been especially effective in archaeology. It has revealed dozens of lost major historical sites concealed beneath overgrown brush and forests. From Canadian forts to Mayan settlements, check out these 32 significant finds from lidar.

Space has been called the final frontier of innovation and investment for decades. Many innovators say the ocean is the new space, the vast majority of whose hidden depths remain obscure. In this podcast episode, business-minded experts discuss the opportunities founders see in the ocean, including seagrass restoration, underwater cable networks, and more.

This four-part video series explains the massive effort to raise, repair, and refloat the Pacific Fleet—detailing the engineering challenges, diving operations, and months of around-the-clock work that restored all but three damaged ships to active service.

A fun interactive on how old ships’ logs are giving scientists new insights into the past and future of the Earth’s changing climate (w/maps and pictures).

Developed following a five-week expedition to the southern continent, "Life Under the Ice" allows users to examine a petri-dish-like microscopic world and uncover recordings of organisms that can withstand, or even thrive, in the harsh environment.

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.

This 28-minute podcast dives into the political ramifications of two Ming dynasty-era ships found in the South China Sea in October 2022. The ships, filled with well-preserved porcelain and timber, were found 1,500 meters—about 4,900...

The British HMS Challenger research vessel identified metal-rich seafloor rocks between Hawaii and Mexico in the 1870s, but rules governing which nations control which parts of the ocean were not established until 1958 by the UN. It later established the ISA to oversee mineral-related operations in international waters.

International Seabed Authority negotiators have spent over a decade drafting regulations that all countries would have to follow before collecting minerals from the seabed. Because deadlines to finalize these agreements have been missed, some entities have discussed unsanctioned mining, despite about three dozen ISA countries calling for a pause on activity and automakers and tech firms pledging they will not use seabed minerals.

The loss of the Titan submersible amid its June 2023 dive to explore the wreckage of the Titanic captured headlines worldwide. Christine Dawood had given up her seat on the trip of a lifetime to her 19-year-old son, Suleman, so he could experience the dive with his father. She has since written a book about her experience of the tragedy and about life in its aftermath.

In 1943, engineers spent three months using 21 giant winches and an intricate cable system to right the capsized USS Oklahoma. It was the largest naval salvage effort ever attempted at the time and remains one of the most complex in history.

Humpback flukes (or tails) are as individually distinct as fingerprints, which means a single photo is enough to match a whale to its full sighting history. Every upload adds a chapter (the database goes back to the 1970s) and the site uses AI to render that data as narrative, not just data.

The pod rammed the boat’s rudder for about 45 minutes. Authorities were able to get crew members to land safely, but their yacht was irreparably damaged. Check out the story and photos here.
