New discoveries made on James Cameron's deep-sea dive: San Diegan reviewed 25 hours of dive video

SAN DIEGO - Director James Cameron, who is known for making blockbuster movies like "Titanic" and "Avatar," made headlines again for traveling to the deepest part of the ocean and a San Diegan played a starring role.

In March 2012, Cameron got into a 24-foot submarine he designed and worked on for seven years. He was the first person to successfully travel 7 miles to the deepest part of ocean called the Challenger Deep.

"It's deeper than Mount Everest is high," said San Diegan Natalya Gallo, who is with the Scripps Institute of Oceanography. She was selected to study 25 hours of video recorded by five cameras on the sub. She made some incredible discoveries.

"The identification of what might probably be two new species," Gallo said.

One is a sea cucumber about four to five inches long that is under a lot of pressure from the water.

"If you took the Eiffel Tower, inverted it and rested it on your big toe, that's the amount of pressure they are feeling on their body," said Gallo.

The other discovery was made in an area northeast of Australia near Papua New Guinea in the North British Trench. No pictures are available yet but Gallo called it a squid worm.

"This is a worm that is about 4 inches in length and has multiple feeding appendages that come out of its head that it uses to feed with," she said.

Gallo made another interesting discovery in a new area called the New Britain Trench. She says there is an interesting connection between humans and the deep sea that goes down a good 5 miles.

"A lot of presence of terrestrial influence like sticks and coconuts... making it down 5 miles," she said.

Gallo hopes these discoveries will remind people of the need to care for our oceans.Her findings and more photos will be published by National Geographic in May. A documentary about the record-breaking expeditions by Cameron will be out later this year on National Geographic's cable channel.
