Rare specially issued "buoy placement" example of this US Coast Survey chart of Pensacola Harbor, published separately on thick paper.
It appears that the this chart of Pensacola Harbor, originally issued in 1857, was later updated in 1864 to show the buoy placements made by Captain T.A. Jenkins. The chart was never issued in an official Coast Survey report.
The chart provides a detailed look at Pensacola Harbor and environs (extending from The Lagoon, Warrigton and Santa Rosa Island to Pensacola and the United States Live Oak Plantation. The chart also includes detailed navigational notes, tidal notes and sailing directions.
Printed on thick paper, the chart is in near fine condition.
The United States Office of the Coast Survey began in 1807, when Thomas Jefferson founded the Survey of the Coast. However, the fledgling office was plagued by the War of 1812 and disagreements over whether it should be civilian or military controlled. The entity was re-founded in 1832 with Ferdinand Rudolph Hassler as its superintendent. Although a civilian agency, many military officers served the office; army officers tended to perform the topographic surveys, while naval officers conducted the hydrographic work.
The Survey’s history was greatly affected by larger events in American history. During the Civil War, while the agency was led by Alexander Dallas Bache (Benjamin Franklin’s grandson), the Survey provided the Union army with charts. Survey personnel accompanied blockading squadrons in the field, making new charts in the process.
After the Civil War, as the country was settled, the Coast Survey sent parties to make new maps, employing scientists and naturalists like John Muir and Louis Agassiz in the process. By 1926, the Survey expanded their purview further to include aeronautical charts. During the Great Depression, the Coast Survey employed over 10,000 people and in the Second World War the office oversaw the production of 100 million maps for the Allies. Since 1970, the Coastal and Geodetic Survey has formed part of the National Oceanic and Atmospheric Administration (NOAA) and it is still producing navigational products and services today.
