NOAA: New Alaska navigational chart makes increased Arctic shipping safer; Kotzebue Harbor chart replaces measurements last taken in 19th century. NOAA formally presented today to Alaska officials a new nautical chart for Kotzebue Sound in the Alaskan Arctic, a sparsely charted region that is seeing increased vessel traffic because of the significant loss of summer sea ice. The new chart depicts the full range of depth measurements and object detection acquired during a full ocean bottom survey last summer by the NOAA hydrographic survey ship Fairweather.

NOAA Ship Fairweather, a 231-foot survey vessel, departed Kodiak, Alaska, today on a mission to conduct hydrographic surveys in remote areas of the Arctic where depths have not been measured since before the U.S. bought Alaska in 1867. NOAA will use the data to update nautical charts to help mariners safely navigate this  important but sparsely charted region, which is now seeing increased vessel traffic because of the significant loss of  Arctic sea ice. Over the next two months, Fairweather will conduct hydrographic surveys covering 402 square nautical miles of navigationally significant waters in Kotzebue Sound, a regional distribution hub in northwestern Alaska in the Arctic Circle.

As Arctic ice recedes, countries are looking forward to faster, safer and more efficient sea routes across the top of the world. Responding to a request from the U.S. Navy, U.S. Coast Guard, Alaska Maritime Pilots and the commercial shipping industry, NOAA sent one of its premier surveying vessels, NOAA Ship Fairweather, to detect navigational dangers in critical Arctic waters that have not been charted for more than 50 years. Fairweather, whose homeport is Ketchikan, Alaska, will spend July and August examining seafloor features, measuring ocean depths and supplying data for updating NOAA’s nautical charts spanning 350 square nautical miles in the Bering Straits around Cape Prince of Wales.
