A marine rewilding initiative to restore an underwater kelp forest in West Sussex is celebrating "remarkable" results, a wildlife trust has said.

The project was launched after the implementation of a new bylaw prohibiting trawling in a 117 sq mile (302 sq km) coastal area between Shoreham-by-Sea and Selsey in March 2021.

Celebrating its fourth anniversary, Sussex Kelp Recovery Project (SKRP) researchers have reported positive signs of recovery, including an increase in the populations of lobster, brown crab, angelshark and short-snouted seahorse.

Last year’s increase was due to an unusual amount of ocean warming

A Brittany, France-based duo is making leaps and bounds toward mycelium-core board production.

Fast-moving underwater avalanches, known as turbidity currents, are responsible for transporting vast quantities of microplastics into the deep sea, according to new research published today.

Retreating glaciers created 2,500km of “new” coastline and 35 “new” islands in the Arctic between 2000 and 2020, according to a new study.

Canadian deep-sea mining firm The Metals Company (TMC) has announced it “initiated a process” with U.S. regulators to apply for both exploration and exploitation licenses, potentially circumventing the international regulator. TMC’s process with the U.S. National Oceanic and Atmospheric Administration falls under the Deep Seabed Hard Mineral Resources Act of 1980 (DSHMRA), which was established as an interim legal framework for the recovery of seabed mineral resources prior to the creation of an international regulatory framework under the United Nations Convention on the Law of the Sea (UNCLOS).

TMC made the announcement via a press release and a public-facing investor call just before the conclusion of the latest meeting of the 36-member council of the International Seabed Authority (ISA), the U.N.-affiliated regulator responsible for overseeing deep-sea mining in international waters.

Scientists explore a seafloor area newly exposed by iceberg A-84; discover vibrant communities of ancient sponges and corals.

Deep-sea ecosystems typically rely on nutrients from the surface slowly raining down to the seafloor. However, these Antarctic ecosystems have been covered by 150-meter-thick (almost 500 feet) ice for centuries, completely cut off from surface nutrients. Ocean currents also move nutrients, and the team hypothesizes that currents are a possible mechanism for sustaining life beneath the ice sheet. The precise mechanism fueling these ecosystems is not yet understood.

The world's oceans harbor a cultural heritage of sunken ships, remains of those lost in the transatlantic slave trade and Indigenous islanders' spiritual ties to the sea that must be protected, NGOs and native peoples say.

Mining companies are poised to mine the deep sea – but opposition is growing. What is the environmental cost, and are these metals actually needed?

On the west coast, local people have gone to court to try and force a rethink of the impacts of oil and gas exploration

Ocean literacy is the compass guiding us toward a sustainable future, empowering us to understand the risks and take meaningful action.

Ocean literacy is about how the ocean influences us and how we are influenced by the ocean.

We may have been taught that oceans are divided into named entities like the Atlantic or Pacific, but these are human constructs; the ocean operates as a single, interconnected system. Currents, warming, and marine species pay no heed to our geographic labels.

there cannot be a healthy planet without a healthy ocean
