Under pressure: Amphipod uses aluminum to survive in the deep sea

Crushing pressures and freezing temperatures prevent many animals from surviving in the deepest depths of our oceans; yet, somehow, a deep-sea amphipod beats all odds and is able to survive and flourish where few other animals can. Scientists have revealed how these amphipods survive under so much pressure.

Deep Sea Vampires and Octopods

Happy (early) Halloween from the depths of the sea! The two animals from this study live in the deep sea and not much is known about their lives. I’m talking about a deep-sea octopus named Japetella diaphana and a vampyromorph named Vampyroteuthis infernalis (more commonly known as the vampire squid). Tropical, Temperate, and Deep-Sea The scientists […]

Hiding at its best: Ultra-black fish of the deep sea

Animals stay hidden from predators using different skin colors and patterns as camouflage. Scientists recently discovered a unique way some fish use ultra-black pigment to hide in the dimly-lit waters of the deep sea.

Telling time in the deep sea

Can animals tell time in the pitch black of the deep-sea? Find out how researchers Dr. Audrey Mat and others discovered that hydrothermal vent mussels use the motion of the ocean to pace their days.

Deep Sea: The Final Frontier

With the decade drawing to a close, it is a good time to look toward the future and start thinking about what the next decade holds for scientific discovery. Star Trek has popularized the idea of outer space as “the final frontier.” But what if it’s really the deep sea?

Into the deep: Deep sea mining is upon us, whether you would risk it or not

While we have a lot to discover about the deep sea, we do know that in the depths of the ocean are a number of valuable minerals and metals like gold, manganese, and cobalt. Yet with so little known, companies are ready to dive into the cold deep, gathering these metals for economic gain.

Top 5 Highlights of Deep Sea Exploration in 2017

What have this year’s deep sea exploration expeditions encountered so far? Read more to find out!

Hide-and-Go-Seek in the Deep Sea

In the deep sea off the coast of Antartica, sea urchins are getting crafty to avoid predation from king crabs. In the face of global climate change, their tactic may become less effective while the predators become more abundant. Find out more here.

Decomposition in the Deep Sea

Whale carcasses that fall to the seafloor provide large amounts of food to deep-sea environments. Though ecologically important, little is known about whale falls and the communities they harbor in the vast Atlantic Ocean – all information comes from the Pacific. What happens to large mammals that sink to the bottom of the Atlantic and […]

Carbon sinks: Diatoms in the deep sea

Fast-sinking phytoplankton particles deliver carbon from the surface to the deep ocean. Are plankton cells still able to survive when they sink to the deep ocean? If so, how long may they survive without any sunlight?

Staying ahead of commercial exploitation in the deep sea

The first seafloor massive sulfide mine in the Pacific is expected to begin commercial operation in 2017. Licenses have already been granted and environmental impact assessments conducted, but we know little about the marine communities surrounding sulfide deposits in the ocean. This study characterizes such communities in a future mining exploration site.

The Role of Eels in Deep Sea Food Webs

Humans have made amazing strides in exploring and understanding the world, and even the universe, around us; but right off the coast looms a large, mysterious entity: the deep sea. For as much as we know about coastal zones and the continental shelf, we know very little about the organisms, communities, and ecology of the […]

Fossilized Deep-Sea Corals Reveal Ancient Ocean Circulation Patterns

An increase in atmospheric carbon dioxide concentrations helped end the last ice age. But what caused the CO2 increase in the first place? A team of scientists used the fossilized skeletons of deep-sea corals to find out.

Upward and onward: how deep-sea larvae utilize vertical swimming to disperse across ocean basins

Deep-sea larvae show vastly different dispersal ability and pathways based on simulating how they swim.

Life in the Abyss: the ecological impacts of deep-sea mining

Did you know that about 95% of the ocean is unexplored? The deep ocean is logistically very difficult to access, so how do scientists study organisms that live hundreds of meters below the sea surface? The landscape of the deep-sea is diverse and certain structures such as polymetallic nodules, supports a vast array of marine […]

Danger in the deep: uncovering the vertical movement patterns of vulnerable deep-sea sharks

Deep-sea sharks are one of the most poorly studied groups of animals on the planet, yet, their populations are highly threatened by fisheries bycatch. Scientists in The Bahamas develop new field approaches to begin unearthing the vertical movements of a vulnerable deep-sea shark, the Cuban dogfish, and their findings from could help significantly reduce fisheries […]

The backbone of an ecosystem: bone-eating zombie worms control biodiversity at deep-sea whale falls

Zombies are real – but they are nothing like the ones from The Walking Dead. No, these zombies are worms that live in the ocean. And instead of brains, they eat and break down bones. In fact, these zombie worms are quite important to food webs. Click here to find out more about zombie worms […]

The Difference between Dippers and Divers: Plastic Pollution in Deep-Diving Seabirds

Plastic pollution is commonly imagined to be an issue that affects the sea surface. However, many small pieces of plastic sink into deeper waters. In this post, we look at research by scientists from Brazil set out along the Brazilian coastline to find out if plastic pollution is only a problem for surface-feeding birds, or […]

Ocean Tech: Using Robots to Conduct Deep-Sea Research

The deep sea is the largest habitat on Earth, but with freezing water and high pressures it is difficult for scientists to study this ecosystem. With the help of technological advances over the past decades, it is becoming easier to unveil some of the mysteries of the deep. Read on to find out how.

Benthic biology on a thermally boring deep-sea ridge

The deep ocean is vast and full of neat ocean dwellers, many of which scientists know little about. One way to investigate them is from images and videos captured during deep-sea exploration efforts using submersibles. A group of scientists did just that to quantify the benthic assemblages at different depths and a variety of substate […]
