Atlantic Neptune Part 2 – Item 12

United Kingdom Hydrographic Office, Bay of Fundy to Block Island, 1887. Updated to 2013
This modern chart is used by present-day mariners. When compared to Des Barres’ chart of the same area, one notices how similar the charts are in appearance. Because Des Barres utilized scientific surveying techniques, his charts closely resemble modern ones of the area. Although originally produced in 1887, this chart contains updates, referred to as mariner’s notices, to March 2013. Today, navigators receive timely marine safety information for the correction of charts on a constant basis, rather than having to wait for publications such as The Atlantic Neptune to become available.
