Ships entering the Port of Charleston will have a new and improved nautical chart that covers a larger area to ensure safer navigational approaches into the harbor.
New chart 11525 (Charleston Harbor Entrance and Approach) replaces the old chart 11523 (Charleston Harbor Entrance). It expands chart coverage further east, covering an additional 345 square nautical miles that wasn’t on the old chart.
NOAA has issued a new nautical chart for the Delong Mountain Terminal, a shallow draft port servicing the Red Dog Mine, one of the world’s largest producers of zinc concentrate, on the western coast of Alaska in the Arctic. New chart 16145 fills in historically sparse depth measurements, using new survey data recently acquired specifically for this chart.
