Records of Spanish shipwrecks combined with tree-ring records show the period 1645 to 1715 had the fewest Caribbean hurricanes since 1500, according to new University of Arizona-led research. The study is the first to use shipwrecks as a proxy for hurricane activity.

When Sir John Franklin and more than 100 sailors from the British Navy set sail in 1845 aboard the HMS Erebus and HMS Terror to discover a Northwest Passage, they had no idea that not one of them would live to tell the story of the expedition.

Whilst undertaking detailed seabed scanning for the development of windfarm projects in the East Anglia Zone, off the coast of Norfolk and Suffolk, windfarm developers ScottishPower Renewables (SPR) and Vattenfall uncovered something they weren’t expecting – an ‘uncharted’ wreck of a WWI German submarine, missing in action since 1915.

NOAA archaeologists have discovered the battered hulls of two 1800s whaling ships nearly 144 years after they and 31 others sank off the Arctic coast of Alaska in one of the planet's most unexplored ocean regions.

In Greece, underwater excavations of Lechaion, ancient Corinth’s partially submerged harbour town, reveal the infrastructure of more than a thousand years of flourishing maritime trade.

The Royal Research Ship Discovery has completed her first year of research. Over a series of nine research expeditions, scientists studied the seasonal events taking place in UK shelf waters throughout the year.

A team of underwater archaeologists from the University of South Carolina raised three Civil War cannons – each weighing upwards of 15,000 pounds – from the silty sediment of South Carolina’s Great Pee Dee River near Florence, S.C.

Scanning sonar from a scientific expedition has revealed the remains of a previously unknown shipwreck more than a mile deep off the North Carolina coast. Artifacts on the wreck indicate it might date to the American Revolution.

Researchers from the University of Hawai'i (UH) and NOAA's Office of National Marine Sanctuaries today announced the discovery of an intact "ghost ship" in 2,000 feet of water nearly 20 miles off the coast of Oahu.

Increasing confidence that a piece of aluminum aircraft debris found on a remote, uninhabited South Pacific atoll came from Amelia Earhart’s Lockheed Electra has bolstered speculation that a sonar anomaly detected at a depth of 600 feet off the west end of the island is the lost aircraft.
