Spotlight: Miles Deep In the Mariana Trench, A New Fish Species Is Discovered

There’s exciting news coming out of the Mariana Trench’s mind-boggling depths. Deep sea explorers discovered a snailfish species living more than five miles — FIVE MILES! – deep in the Mariana Trench. It has been named the Pseudoliparis swirei, and according to this National Geographic article, “…scientists suspect they are unlikely to ever find a fish that lives much deeper.”

But it’s the deep sea, the least-explored part of our earth, so who can imagine what else marine researchers may find. As University of Washington marine biologist Mackenzie Gerringer notes,

“We think of it as a harsh environment because it’s extreme for us, but there’s a whole group of organisms that are very happy down there,” said lead researcher Mackenzie Gerringer, a marine biologist at the University of Washington. Further research in these depths may yield even more weird discoveries. “There are a lot of surprises waiting.”

Spotlight: Exploring the oceans – “there’s still 97 percent”

“Only the ocean remains as the last great unexplored portion of our globe; so it is to the sea that man must turn to meet the last great challenge of exploration this side of outer space.”
–Deep Challenge (1966) by H. B. Stewart

Marine biologist David Gallo brings the mind-bending world of ocean exploration alive in his latest talk about the fascinating and largely unexplored undersea world. As he notes, “Today we’ve only explored about 3 percent of what’s out there in the ocean. Already we’ve found the world’s highest mountains, the world’s deepest valleys, underwater lakes, underwater waterfalls … . There’s still 97 percent, and either that 97 percent is empty or just full of surprises.”

Watch this – it’s entrancing:

Gallo and his team, NOAA’s Ocean Explorer teams, Dr. Edith Widder, and so many more, are among those who’ve been exploring the oceans’ depths for years. This year is a pivotal time in deep sea exploration – with James Cameron’s DeepSea Challenge, Richard Branson’s Virgin Oceanic and Dr. Sylvia Earle’s DOER marine all aiming to explore at the ocean’s deepest point – the fabled Mariana Trench. Before James Cameron reached the bottom of the Trench last month, there had been a 52 year drought — only Jacques Piccard and Don Walsh had done it before — in 1960.

With this ocean-oriented race to the bottom, we’re surely on the brink of  vast and astonishing discoveries of life in the least-hospitable, oxygen-starved depths of our planet.

Spotlight: Deepest-ever descent, Mariana Trench

Wired is featuring a terrific resurrection of this exciting ocean exploration story –

“Fifty-one years ago this Sunday, Swiss engineer Jacques Piccard and Navy oceanographer Don Walsh descended to the bottom of the Mariana Trench, seven miles below the sea’s surface. It’s the lowest point on Earth, and deeper than any human had gone before — or since.”

German design student Roman Wolter created this animated film using narration from an excellent 2005 interview of the late Piccard himself. It really brings the remarkable 1960 expedition alive.
