To its north lies the Sinai Peninsula, the Gulf of Aqaba, and the Gulf of Suez, which leads into to the Suez Canal. Hosts Regina G. Barber and Emily Kwong dive into this debate and talk about what science has to say. “The ocean is highly connected, so there will probably still be impacts on these animals,” Judah said. The Australian Museum respects and acknowledges the Gadigal people as the First Peoples and Traditional Custodians of the land and waterways on which the Museum stands. Envision a world where everyone can enjoy clean air, walkable cities, vibrant landscapes, nutritious food and affordable energy.
- It is both an untouched, mysterious frontier far from sight, and a critical, contested space for human industrial or scientific extraction.
- The last one approaches the deep sea as a colonial space in which the past, the present, and new alternative futures are claimed.
- Its margin, referred to as the continental shelf, can extend up to 500 metres below the water’s surface; only after this point does the deep sea begin.
- These findings shed more light on how the depth, regional setting, and seafloor disturbance via seismic activities and nutrient supply from land interact to structure marine ecosystems.
- Except for the areas close to the hydrothermal vents, this energy comes from organic material drifting down from the photic zone.
- The deep ocean plays an especially critical role in climate regulation, carbon storage, heat transport, and many ways in which scientists are only beginning to fully understand.
DEEP WATER COLUMN
These metals are essential for the production of electronics, renewable energy technologies, and electric vehicles. The deep sea is defined as the part of the ocean that lies below the photic zone, where sunlight does not penetrate. This region begins at a depth of approximately 200 meters (656 feet) and extends to the ocean floor, which can reach depths of over 11,000 meters (36,000 feet) in places like the Mariana Trench. The deep sea is characterized by extreme conditions, including immense pressure, near-freezing temperatures, and complete darkness. The deep sea oscillates between visibility and invisibility depending on the stakes involved. It is both an untouched, mysterious frontier far from sight, and a critical, contested space for human industrial or scientific extraction.
- Another frequently used definition considers all waters beyond the reach of light from the surface to be part of the deep sea.
- The females have an organic “fishing rod” complete with bait attached to their heads, and in many species, the bait actually glows.
- It does so through interdisciplinary insights from the social sciences and reflections that are profoundly anthropological in theory.
- In the Antarctic, for instance, the tremendous ice masses weigh down the continent considerably.
- The UK Overseas Territories are collectively responsible for Marine Protected Areas that span over 4.3 million sq.
- Here we bring together the latest deep-sea science, traditional knowledge, and expert insights that shape our work to safeguard these incredible habitats and species.

“We found differences in community composition and diversity between trenches, linked to depth and nutrient input Deep Sea from surface waters,” Dr Swanborn said. This entry aims to encourage deeper engagement with this ethnographic realm, asserting the importance of claiming a voice within both scientific discourse and broader societal debates. A glass sponge known as ”Advhena magnifica” in the Pacific Ocean being collected in 2016, at a depth of 2,000 meters. In addition to feeding, creatures of the deep use light in flashy displays meant to attract mates. Or, animals use a strong flash of bioluminescence to scare off an impending predator. The bright signal can startle and distract the predator and cause confusion about the whereabouts of its target.
The aim is to build the largest-ever dataset of these habitats and help shape legal protections. “For example, historically seismically active areas in the Japan Trench were dominated by low-diversity organisms that had adapted to their environment, while the more stable under-riding slope supported more diverse communities,” she explained. And in the Izu-Ogasawara Trench, at a depth of about 9km (30,000ft), extensive sea lily meadows were discovered. These observations were part of a crewed submersible mission to the hadal zone, the deepest part of the world’s oceans, in the Japan, Ryukyu, and Izu-Ogasawara trenches of the Northwest Pacific Ocean during six submersible dives from August to September 2022.
China’s Energy Motivations
Below the ocean’s surface is a mysterious world that accounts for over 95 percent of Earth’s living space—it could hide 20 Washington Monuments stacked on top of each other. As you dive down through this vast living space you notice that light starts fading rapidly. By 650 feet (200 m) all the light is gone to our eyes and the temperature has dropped dramatically.
The Critical Minerals Conundrum: What You Should Know
This risk may dissuade mining companies from pursuing mining in international waters in the near term. Minerals such as lithium, cobalt, nickel and rare earth elements are essential ingredients in everything from wind turbines and electric vehicles to cell phones, medical technologies and military infrastructure. Mining for these materials on land is already well established, but with demand surging, some are now looking to tap the seafloor for its millions of square kilometers of metal ores. This ability to study the deep-sea is still a serious limiting factor in many places all over the world, because of the high cost and complex engineering needs, and we are actively developing technology that can be used for deep-sea research using small local boats. For example, we are working with St Helena and Belize to trial a specialised underwater camera system that can be used at 1,000 metres, that is also cheap and easy to use.
Red Sea crisis
While robots, with their physical capacity to perform tasks that humans cannot, can bring us emotionally and epistemologically closer to the ocean, they can also obscure the ethical implications of violence in marine ecosystems. By outsourcing harm to non-human actors, they displace responsibility (Braverman 2020, 162). The mechanisation of knowledge production in marine environments—deciding which species ‘make live’ or ‘make die’—not only obscures human agency but also generates a space of biopolitical governance, where life is managed remotely and often invisibly (Braverman 2020, 148).
Landmark conviction exposes Sri Lanka’s deep-rooted illegal elephant trade
It blurs the boundaries between the visible and the invisible, the interior and the exterior, the knowable and the unknowable, the familiar and the alien. In doing so, it opens up space for porous, entangled, and multi-species encounters but also for rethinking the past and imagining alternative futures. In the deep-sea food is scarce, but it is also a great place to hide in the dark away from hungry predators. Some creatures have adapted a way of life that takes advantage of both the plentiful surface waters and the safety of the deep. The cracks release buried petroleum-based gas and liquid from deep underground where they formed over millions of years.
