Recently we reported on a mysterious shipwreck that marine scientists stumbled upon in deep waters off the coast of North Carolina, a ship they believe could be from the 18th century — but could there be many more ships out there? Scientists think the answer is yes.

A research expedition aboard the research ship Atlantic was out conducting research on deep-sea methane seeps along the East Coast when they found the shipwreck, which had glass bottles, an iron chain, navigational equipment, and many other artifacts, Christian Science Monitor report.

But what’s perhaps most exciting is the fact that the sea floor in this area could be littered with shipwrecks, making it a treasure trove of maritime time capsules.

The reason why is that the wreck was found in what is known as the Gulf Stream, a maritime “highway” to ports across North and South America as well as the Caribbean. Loads of ships throughout the years have sailed down the Gulf Stream, and many of them were caught in ferocious storms and sank to the bottom far, far beneath the waves.

The only problem is, it’s so deep that scientists have trouble accessing these spots. After all, the research team that found this most recent shipwreck had explored the area several times and may have come within just 100 meters of the wreck previously.

It’s not easy to take a peak at the sea floor a mile down, so looking for these shipwrecks can sometimes be like looking for a needle in a haystack. But most likely there are countless shipwrecks sitting on the sea floor at sites like that, just waiting to be found and explored.
