The Soviet Union used the waters east of Novaya Zemlya to dump reactors, spent nuclear fuel and solid radioactive waste from both the navy and the fleet of nuclear-powered civilian icebreakers. About 17,000 objects were dumped in the period from the late 1960s to the late 1980s. Most of the objects are metal containers with low- and medium level radioactive waste. The challenge today, though, are the reactors with high-level waste and spent uranium fuel, objects that will pose a serious threat to the marine environment for tens of thousands of years if nothing is done to secure them.
The reactors from the submarines K-11, K-19 and K-140, plus the entire submarine K-27 (in the Kara Sea) and spent uranium fuel from one of the old reactors of the Lenin-icebreaker have to be lifted and secured. Also, the submarine K-159 (in the Barents Sea) that sank north of Murmansk while being towed for decommissioning in 2003 have to be lifted from the seafloor, the experts conclude. A study report made for Rosatom and the European Commission has evaluated the costs of lifting all six objects, bringing them safely to a yard for decommissioning and securing the reactors for long-term storage. The estimated price-tag for all six will €278 millions, of which the K-159 is the most expensive with a cost of €57.5 millions. Unlike the submarines and reactors that are dumped in relatively shallow waters in the Kara Sea, the K-159 is at about 200 meters depth, and thus will be more difficult to lift.

A competition for the North Pole heated up in May 2019, as Canada became the third country to claim—based on extensive scientific data—that it should have sovereignty over a large swath of the Arctic Ocean, including the pole. Canada’s bid, submitted to the United Nations’s Commission on the Limits of the Continental Shelf (CLCS), joins competing claims from Russia and Denmark. Like theirs, it is motivated by the prospect of mineral riches: the large oil reserves believed to lie under the Arctic Ocean, which will become more accessible as the polar ice retreats. And all three claims, along with dozens of similar claims in other oceans, rest on extensive seafloor mapping, which has proved to be a boon to science…
Coastal nations have sovereign rights over an exclusive economic zone (EEZ), extending by definition 200 nautical miles (370 kilometers) out from their coastline. But the 1982 United Nations Convention on the Law of the Sea opened up the possibility of expanding that zone if a country can convince CLCS that its continental shelf extends beyond the EEZ’s limits…..Most of the 84 submissions so far were driven by the prospect of oil and gas, although advances in deep-sea mining technology have added new reasons to apply. Brazil, for example, filed an application in December 2018 that included the Rio Grande Rise, a deep-ocean mountain range 1500 kilometers southeast of Rio De Janeiro that’s covered in cobalt-rich ferromanganese crusts.
To make a claim, a country has to submit detailed data on the shape of the sea floor and on its sediment, which is thicker on the shelf than in the deep ocean. …CLCS, composed of 21 scientists in fields such as geology and hydrography who are elected by member states, has accepted 24 of the 28 claims it has finished evaluating, some partially or with caveats; in several cases, it has asked for follow-up submissions with more data. Australia was the first country to succeed, adding 2.5 million square kilometers to its territory in 2008. New Zealand gained undersea territory six times larger than its terrestrial area. But CLCS only judges the merit of each individual scientific claim; it has no authority to decide boundaries when claims overlap. To do that, countries have to turn to diplomatic channels once the science is settled.
The three claims on the North Pole revolve around the Lomonosov Ridge, an underwater mountain system that runs from Ellesmere Island in Canada’s Qikiqtaaluk region to the New Siberian Islands of Russia, passing the North Pole. Both countries claim the ridge is geologically connected to their continent, whereas Denmark says it is also tied to Greenland, a Danish territory. As the ridge is thought to be continental crust, the territorial extensions could be extensive)
Tensions flared when Russia planted a titanium flag on the sea floor beneath the North Pole in 2007, after CLCS rejected its first claim, saying more data were needed. The Canadian foreign minister at the time likened the move to the land grabs of early European colonizers. Not that the North Pole has any material value: “The oil potential there is zip,” says geologist Henry Dick of the Woods Hole Oceanographic Institution in Massachusetts. “The real fight is over the Amerasian Basin” where large amounts of oil are thought to be locked up…
There’s also a proposal to makethe North Pole international, like Antarctica (South Pole), as a sign of peace, says Oran Young, a political scientist at the University of California, Santa Barbara. “It seems a very sensible idea.”

The Soviet Union during the 1960s and 70s dumped several hundred containers with solid radioactive waste in the Blagopoluchie Bay in Novaya Zemlya. Back then, these waters were covered with ice overwhelming parts of the year. Today, that is quickly changing. The bay located in the northern part of the Russian Arctic archipelago is now ice-free increasing parts of the year. With the retreating ice follow new species.
Researchers from the Russian Shirshov Institute of Oceanology have comprehensively studied the eco system of the bay for several years. Among their key findings is a quickly growing number of snow crabs. In this year’s research expedition to the remote waters, the researchers were overwhelmed by the numbers. According to the institute, the crab invasion can be described «as avalanche».
The number of crabs in the area is now estimated to almost 14,000 per hectare, the institute informs. With the help of underwater photo and video footage, the researchers have studied how the crab expansion is leading to a other reduction in other marine life on the sea bottom. A further spread in the other parts of the Kara Sea is imminent, and the Russian Fisheries Agency (Rosrybolovstvo) believe that the Kara Sea will ultimately become an area with commercial crab fishing.
But Kara seas is a major nuclear waste dump…No major leakage from the radioactive materials have so far been registered. Soviet authorities are believed to have dumped about 17,000 containers with solid radioactive wastes in Arctic waters and primarily in the Kara Sea. More than 900 containers are located on the bottom of the Blagopoluchie Bay. Also a number of reactor compartments were dumped, as well as three nuclear subs and other nuclear materials.
