NOAA Office of Coast Survey has released a new nautical chart for the Arctic, which will help mariners navigate the Bering Strait. Chart 16190 (Bering Strait North) incorporates precise depth measurements acquired recently by NOAA Ship Fairweather hydrographic surveys.
Coast Survey has also released a new edition of Chart 16220 (St Lawrence Island to Bering Strait).
“Our Arctic Nautical Charting Plan identified the need for 14 new charts in the Arctic,” explains Commander Shep Smith, chief of Coast Survey’s Marine Chart Division. “Chart 16190 was high on our list of priorities, since the Bering Strait is the maritime gateway from the Bering Sea in the Pacific Ocean to the Chukchi Sea in the Arctic Ocean.”
As the nation’s nautical chartmaker, Coast Survey produces the country’s traditional paper charts for coastal waters, territorial waters, and the Great Lakes. We maintain the Print-on-Demand charts that you can purchase from OceanGraphix and East View Geospatial. We make the nation’s raster navigational charts (NOAA RNC®) and electronic navigational charts (NOAA ENC®). And the free downloadable BookletCharts. But did you know we produce international charts, too? NOAA has five international charts covering the Northeastern Pacific Ocean and the Bering Sea… and we just published our sixth, for the opposite coast.
International mariners entering U.S. waters around southwestern Florida now have a new international (INT) nautical chart to help ease their transit. The new chart, INT 4148, has the same information as Chart 11420, Havana to Tampa Bay, but the depictions are converted to the metric system. (Most U.S. charts use either feet or fathoms for depth measurements). INT charts also use some different symbology, so Coast Survey makes those modifications as well.
