ANCHORAGE, Alaska — An international agency that sets standards for marine safety has approved two-way shipping routes into the Arctic Ocean through the Bering Strait.
The International Maritime Organization, an arm of the United Nations, accepted routes proposed by the United States and Russia for safe navigation in the water between Alaska and Russia’s Chukotskiy Peninsula.
The action designated routes for northbound and southbound traffic on both sides of the Diomede Islands within the Bering Strait, a chokepoint about 50 miles wide between the northern Bering Sea and the Chukchi Sea.
Six areas of precaution are noted.
The maritime organization also designated three areas to be avoided around Alaska’s Nunivak, King and St. Lawrence islands.
“This is a big step forward as the U.S. Coast Guard continues to work together with international, interagency and maritime stakeholders to make our waterways safer, more efficient and more resilient,” Mike Sollosi, chief of the agency’s Navigation Standards Division, said in a statement.
The routes take effect Dec. 1. Their use is voluntary but they ensure mariners that they can transit in deep water without natural obstructions.
The Coast Guard spent nearly a decade working on safety measures in response to additional Bering Sea and Arctic Ocean ship traffic that followed diminished sea ice brought on by climate warming. The work culminated with a Coast Guard port access route study submitted last year.
Environmental groups pushed for safe shipping measures. They say there are few resources north or south of the Bering Strait to respond to a spill that could cause serious damage to important marine resources such as bowhead and beluga whales, Pacific walruses, ice seals, spectacled eiders and other seabirds.
“These measures will keep vessels on the safest course and reduce the risk of them running aground, colliding, or interfering directly with subsistence hunting,” said Eleanor Huffines of Pew Charitable Trusts.
