The robotic arm of the Jason, a Remotely Operated Vehicle (ROV), collects several stalks of black coral from the seafloor. Read more about how underwater vehicles help ocean scientists study deep-sea...
The robotic arm of a Pisces submersible collects a gold coral colony ( Gerardia sp.) during a research cruise in the Hawaiian Islands. Ocean scientists have radiocarbon-dated some Gerardia specimens...
From discovering new marine life to exploring the wreck of the Titanic , ROV’s and other technology are helping us get a closer look at the more than two thirds of our planet that are underwater...
We drove down a long dirt road on the northern side of Curaçao looking for a remote place to snorkel and sample. After a 30-minute bumpy ride, our team stepped out of the car into a breeze and the...
