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 the new year approaches, NOAA ships and independent contractors are preparing for the nation’s 177th hydrographic surveying season, aiming to collect critically needed ocean and coastal mapping data for 2,525 square nautical miles in high-traffic coastal waters of the continental United States and Alaska. “The science of these surveys underpins the steady flow of commerce and the safety of mariners and coastal communities,” said NOAA Corps Capt. John E. Lowell, director of the Office of Coast Survey and U.S. national hydrographer. More than 13 million jobs are tied to maritime commerce which contributes more than $742 billion to the American economy. U.S.
