Underwater Engineer
Nico Vincent helped discover a famous explorer’s ship at the bottom of the Southern Ocean
Falklands Maritime Heritage Trust
The ship sank more than 100 years ago. Its location was unknown until now.

This past March, a team of scientists and archaeologists made an exciting discovery in the waters around Antarctica. They found the wreck of a ship called Endurance. The ship sank in 1915 after being crushed by sea ice. Led by famous explorer Ernest Shackleton, the Endurance crew made a dangerous journey across the frozen ocean. Amazingly, they all survived. But the lost ship’s exact location remained a mystery for 106 years.
Nico Vincent led the underwater search for the wreck. He’s a subsea engineer and commercial diver. Vincent has spent years searching for shipwrecks. This, he says, was the most challenging search of his career.
This past March, a team of scientists and archaeologists made an exciting discovery. They traveled to Antarctica and searched the waters around it. Eventually, they found the wreck of a ship called Endurance. The ship was crushed by sea ice in 1915. It sank. The Endurance crew had to cross the frozen ocean. They were led by Ernest Shackleton. He was a famous explorer. Amazingly, the entire crew survived the dangerous journey. But the ship was lost. Its exact location remained a mystery for 106 years.
The Search
This underwater drone scanned the seafloor and detected the Endurance.
First, Vincent and his team created a search grid. They released a pair of underwater drones. The drones steered themselves along a path over the grid. They mapped the seafloor using sonar, which relies on sound waves to measure an object’s distance.
The surface of the water was covered in floating sheets of ice roughly 6 feet thick. “We had to engineer our tools from scratch to handle the environment,” Vincent says. To stop the drones from getting lost beneath the ice, a fiber-optic cable kept them tethered to the expedition ship. This connection also allowed a human pilot to take control in an emergency. “We had to be prepared for the unexpected,” explains Vincent.

The Find

The Endurance attempted to make a dangerous journey across the frozen ocean.
After two weeks of searching, Vincent’s team spotted a ship-shaped object on the sonar images. It was lying on the seafloor, nearly 2 miles below the surface. They sent the drone in for a closer look. What the sonar had shown was the Endurance! The ship had been well-preserved in the cold water.
Vincent’s team took 3-D scans to create a virtual model of the wreck. Now the world can see it.
“I’m proud to be part of Shackleton’s legacy,” he says.

Why would a coordinate grid be helpful in planning a thorough search of an area?
To find the Endurance, undersea drones moved over a search grid. The team programmed their movements precisely to make sure they didn’t miss any spots. Create a coordinate grid to plot a drone’s path to study objects on the seafloor.
Materials
graph paper • pencil • ruler • colored pencils (optional)
Procedure
STEP 1 Draw and label the x- and y-axes on your grid paper. Number both axes from 0 to 10 units.
STEP 2 The drone enters the water at (10, 8). Plot this point on your grid and label it D.
STEP 3 Sonar detects an old shipwreck at (3, 6). Plot this point on your grid and label it W.
STEP 4 Ocean currents have swept artifacts from the wreck 1 unit north and 2 units east of W. Plot this point and label it A.
STEP 5 The drone must return to the ship at (7, 3). Plot this point on your grid and label it S.
Analysis
Answer the following questions on a separate sheet of paper.
Write directions for the drone to travel from point D to point W, with a stop on the way to investigate point A.
To return to the ship, the drone must get from point W to point S. Is it closer for the drone to head south then east or east then south? Explain.
