This chart had several features not included on earlier charts in this collection. For example, it lists a telephone number that mariners should call to report pollution spills and it shows the locations of navigational hazards such as submarine pipelines and cables.
As a reflection of the power of changing technology, this chart is also the first in this collection to refer mariners to a NOAA Weather Radio broadcast frequency. NOAA Weather Radio is a nationwide network of radio stations broadcasting National Weather Service warnings, watches, forecasts, and other hazard information 24 hours a day. The National Weather Service also uses this system to broadcast weather...with the push of a button mariners can get current weather conditions and forecasts for their areas, any time, day or night. Earlier nautical charts in this collection directed mariners to storm warnings posted on stations around New York Harbor.
You'll see a note indicating that this chart is based on NAD83. "NAD83" stands for the North American Datum of 1983. Geodetic datums define the size and shape of the Earth and the origin and orientation of the coordinate systems used to map the Earth. A datum can be considered as an arbitrary zero level, or a reference, of the geospatial data's "coordinate system." NAD83 is the horizontal control datum for the United States, Canada, Mexico, and Central America.
Historic Reference
