When was the US Coast Survey established?

The US Coast Survey, which is now known as the National Oceanic and Atmospheric Administration (NOAA) Office of Coast Survey, was established in 1807. Its primary purpose was to survey the coastal waters and create navigational charts to enhance maritime safety during a time when commerce was heavily reliant on maritime trade. The correct year for its establishment is thus 1807, making that the most accurate answer to the question presented.

The year 1836 does not hold relevance as the establishment date of the US Coast Survey. While other options, such as 1878 and 1970, do reflect significant developments in the evolution or restructuring of the survey and related organizations, they are not the founding year. This highlights the importance of identifying the correct historical context and timeline of the US Coast Survey's inception.
