Ancient Greek vessel found in Black Sea is world's oldest intact shipwreck

For three years, an international team of scientists surveyed the floor of the Black Sea, off the coast of Bulgaria. Now, radiocarbon tests have confirmed that the remains of an ancient ship discovered last year date from 400BC, officially making it the world's oldest known intact shipwreck.

The researchers determined that it's possible to use Landsat data to make shipwreck detections (echosounder data, which was also used for the study, can be seen in the inset images)

Satellite data could help in spotting shipwrecks

New research has found that it might be possible to spot coastal shipwrecks by searching for plumes of sediment in imagery collected by NASA's Landsat 8 satellite.

Archaeology vs. Physics: Conflicting roles for old lead

The study of archaeology has long been carried out using tools from the physics lab. What is less well known is that archaeology has also made substantial contributions to physics. This is the story of old lead; why it is important to physics, and what ethical problems it presents to both sciences.
