Chart of the south end of east Florida and Martiers, 1771
Scope and Contents
De Brahm concentrated his surveying efforts on the east coast of Florida, from St. Augustine south to the Keys. This chart of the southern tip of east Florida was included in the English edition of The Atlantic Pilot, along with a chart of the Gulf Stream and a map of the ancient Florida peninsula. De Brahm's meticulous hydrographic survey work is evident in this chart, with its numerous soundings, outlines of shoals, and inclusion of anchoring places. These surveys were eventually used by Des Barres, and the information was included on the charts which make up The Atlantic Neptune.
