On 21 February 2019, Nautilus Minerals Inc. filed for protection from creditors under the Canadian Companies’ Creditors Arrangement Act.  Whilst claiming this as a victory in their decade-long campaign to stop the Nautilus Solwara 1 Project in the Bismarck Sea, local communities and civil society in Papua New Guinea are taking heed that the fight is not over until all Nautilus licences are cancelled.

The waters off the coast of Quebec’s Gaspé Peninsula are part of Canada’s newest marine protected area (MPA). Official protection of the area has been a long time coming, with efforts to have the peninsula designated having started in 2011. This week, Fisheries and Oceans Minister Jonathan Wilkinson made it official.

The Canadian government will create new marine refuges off the western coast that will protect some ancient and fragile glass sponge reefs. The charity, Canadian Parks and Wilderness Society (CPAWS), “is very pleased” that this “ecological treasure” not far from Vancouver will be protected from all bottom-contact fishing. CPAWS and other groups have worked hard to study and secure protection of the reefs.

California based artist and dabbler in the deep sea, Lily Simonson had me at “Party of Yeti’s.” In a new exhibit at the Harvard Museum of Natural History entitled Lily Simonson: Painting the Deep, Simonson features her large scale interpretations of the denizens of the deep. “Inspired by explorations of deep ocean life made in collaboration with Harvard University Professor Peter Girguis, Simonson’s art reflects a passion for the process of science, deep affection for the natural world, and dedication to seeking out and “bringing to light,” the beauty and mystery of places and lifeforms little known and rarely seen.”

Four decades have passed since vibrant clusters of giant, metre-long tubeworms, discovered at hot springs on the ocean floor by Corliss et al.1, were reported in Science. Until then, the ocean floor was considered to be more like a desert than an oasis.

Corliss and colleagues didn’t discover underwater hot springs by accident; rather, they were trying to discover whether the hypothesis that such sites existed was correct. Theories on the movements of tectonic plates had set the course for this discovery with the idea that the mountain ranges that girdle the globe on the ocean floor, called spreading centres, are volcanic sites at the boundaries of tectonic plates. A key clue to the existence of underwater hot springs was the unexpectedly low conductive heat flux in the ocean’s crust2. Convective heat flow through hot springs could solve the riddle of this missing heat. Warm-water anomalies documented above a spreading centre called Galapagos Ridge guided Corliss et al. to the site at which they discovered underwater hot springs (also called hydrothermal vents).

In 2005 a US nuclear submarine hit something solid south-east of Guam. It was reportedly operating at full speed at a depth of about 160 metres when the collision occurred. The nose of the USS San Francisco was so severely damaged that the craft had trouble surfacing. The accident injured 98 submariners. One subsequently died.

It was later revealed the obstacle wasn’t a rival vessel, as speculated, but a large undersea hill. The incident caused huge embarrassment for the world’s most powerful military, but it also reinforced how little we still know about the underwater environment.

It’s one of the coldest, darkest places on earth, full of marine life – much of which is yet to be discovered – with a seabed rich in mineral deposits.

In the last decade, the floor of the deep ocean that lies outside the jurisdiction of any one country has been increasingly explored. A number of parties are assessing the size and extent of mineral deposits that could provide raw materials for everything from batteries and jet engines to wind turbines and mobile phones.

Deep in the North Pacific Ocean, in an area as wide as the United States, billions of potato-sized rocks litter the ocean floor. These lumpy, black-brown balls are full of cobalt, nickel, copper and manganese – valuable minerals that are crucial for electronics and evolving green technologies, such as electric cars and solar panels.
