Deep Sea Explorations Amaze with Live Stream Video

octopus_sea_slug

On Tuesday I wrote about my experience diving in a deep-sea submarine, but going on right now are two live-streaming deep-sea expeditions that allow you incredible access to the deep sea from the comfort of your own home. If you really want to know what the deep sea looks like, you can get an incredible [...]

551 Feet Under the Sea: What It’s Like to Ride in a Deep-Sea Sub

exterior_curasub_underwater_200

I heard a screwing noise as the hatch of our sub was sealed. A bright orange hose from topside that had been inserted into the sub to blow fresh air as we loaded had been removed, and the interior felt warm and damp and close. All was still. Though I’d worried how I’d feel at [...]

How To Visit the Deep Sea

ophiourid_black_coral_noaa_pd_200

For at least the last 15 years, I have dreamed of travelling to the deep sea. If you read this blog regularly or have ever watched a documentary about the deep sea, you understand why. As marine biologist (and co-sighter of the first underwater giant squid) Edith Widder says in one of her many fascinating [...]

Cameron’s Team Divulges Discoveries in Deepest Trenches on Earth

xenophyophore_noaa_pd_200

It’s often said that we know less about the bottom of our own ocean than we do about the surface of Mars. The governments of the world, and our government in particular, seem presently much less than enthusiastic about exploring the oceans of our own planet than in exploring other planets (ocean research seems to [...]

Deep Sea Coral Clings to Oil Platform at Record Gulf Depth

When the Mississippi River flows into the Gulf of Mexico, its odyssey doesn’t end. It enters an underwater valley called the Mississippi Canyon, a world where nutrients from the river nourish some fantastical forms of life. One part of this canyon looks like this: The graceful white sculptures sprouting from carbonate outcrops are Lophelia coral. [...]

To Hades and Back: Nereus Lost

ABOARD THE R/V THOMAS G. THOMPSON—In the early morning hours of Saturday, May 10, we were on the seafloor in the deepest part of the Kermadec Trench when all of the video screens in the Nereus control room went dark. That wasn’t unusual, but it did signal a premature end to our 7-hour dive to [...]

To Hades and Back: Snailfish Surprise in the Kermadec Trench

ABOARD THE R/V THOMAS G. THOMPSON—On the scale of the Pacific Ocean, the Kermadec Trench looks like a thin line snaking down from southwest to northeast just off the northeastern tip of New Zealand’s North Island. But when you zoom in and look even at the coarse detail that the ship’s multi-beam sonar can reveal, [...]

To Hades and Back: One Trench Among Many

ABOARD THE R/V THOMAS G. THOMPSON—Challenger Deep is the deepest spot in the ocean—that we know of, at least. The seafloor is so poorly mapped that there could easily be something deeper out there, but that’s not all that important to us. It’s been visited many times by both human-occupied and remotely operated vehicles, including [...]

To Hades and Back: Feeding Frenzies of the Deep

Chimera_feat

ABOARD THE R/V THOMAS G. THOMPSON—While waiting for the weather to die down and for solutions to problems with our winch and the vehicle, the rest of our non-Nereus science program has continued. We have put both of the landers and the fish trap in the water almost every day so far at varying depths [...]

To Hades and Back: Under the Weather

ABOARD THE R/V THOMAS G. THOMPSON—Our operations have been halted for a second day now while we wait for a storm on the other side of New Zealand to spin itself out. With no samples to process, many of us took a day off to catch up on reading or, for some of the undergraduates [...]

To Hades and Back: Exploring the Deepest Part of the Ocean

Humans have been to every corner of the planet and built either an Internet café or a Starbucks in almost every city. You can find plastic in the middle of the ocean and Mt. Everest base camp is a vast rubbish heap. Satellites monitor virtually every square meter of Earth every day and Google has [...]

Scientists Explore New Zealand’s Deep Sea (Part II)

sea urchin image

We made five planned dives during our voyage, each one a day long. It is a long day for the sub team. It takes several hours to prepare the submersible for the dive, and after seven to eight hours on the seafloor, another round of work is needed to prepare the sub for its next [...]

Scientists Explore New Zealand’s Deep Sea (Part I)

Shinkai 6500 submarine

The JAMSTEC research vessel RV Yokosuka sailed from Nuku’alofa in Tonga this morning, heading towards New Zealand to explore the animal life on deep undersea mountains, or seamounts. A team of 14 scientists from Japan and New Zealand, 41 ships officers and crew are on board. The Yokosuka is the mother ship for the human-operated [...]

Millennia-Old Microbes Found Alive in Deep-Ocean Muck

mud-core

A sparse community of microbes can persist for eons in the clay beneath the deep blue sea. When scientists drilled into the Pacific Ocean bottom and pulled up a long core of clay, they also pulled up microbes living on so little that it was hard for the scientists to tell if they were alive [...]

Four New Species of Deep-Sea Killer Sponge Discovered

new-species-carnivorous-sponge-featured

Four new species of carnivorous sea sponge have been discovered in a place where ridiculous adaptations for sourcing food seem about as widespread as horrific ways to die – the deep sea. Following their discovery in 2012 of the fantastic-looking carnivorous harp sponge (Chondrocladia lyra) off the coast of California and almost four kilometres deep, [...]
