How do you view a chart that shows the depths of the Atlantic Ocean?

Nautical charts of many regions in the Atlantic Ocean are available on the official website of the Office of Coast Survey, NOAA.Gov. The charts cover U.S. coasts,international coasts, and some inner waters of the ocean.

Nautical charts on NOAA.Gov are displayed in a table format where each chart is assigned a number. For each numbered chart, the table displays information about the scale the chart uses and the region the chart displays. The charts are sourced from many different places, so the scales vary greatly. The site also offers an interactive map catalog of all of the Atlantic nautical charts. Users can view a graphic representation of the ocean and click an area to see a chart.
