Fabien Cousteau has finally come on the surface after spending 31 days under water. The duration of his stay is the new world record for maximum days spent living underwater. Fabien and his colleagues organized this stint to study how climate change affects marine life.

French oceanographer Fabien Cousteau recently has registered his name in record books for conducting a 31-day mission underwater, off the coast of Florida. Fabien said that mission has been a significant help for them to collect many months' worth of data in only a few weeks.

During their mission, they conducted various experiments, including predator-prey interactions and studying the effects of climate change and pollution on reefs.

Cousteau said in a press release prior to the splashdown on June 1 that the theme of the Mission 31 was to figure out the human-ocean connection within the lens of exploration and discovery.

Fabien is the grandson of Jacques Cousteau, who was also a famous ocean explorer. Jacques devised many ways to help in advancement of diving techniques. These diving techniques provide to be great help for Cousteau and the rest of the Mission 31 crew. Fabien's grandfather spent 30 days underwater in a pressurized tank while filming his Oscar-award-winning documentary `World without Sun'. Fabien broke his record by spending just one day more living underwater.

"The record was never really the focal point. I knew it was a hook, I knew that symbolic one extra day would get people's attention, curiosity at the very least. This has been a monumental success on multiple levels", said Cousteau who is 46-year-old.
