As we begin to move into our 2016 field season, we are excited to introduce the results of the 450th Anniversary Shipwreck Survey, that the Lighthouse Archaeological Maritime Program (LAMP) carried out over the 2015 field season. The “450th Anniversary Shipwreck Survey” was a project carried out as part of LAMP’s multi-year First Coast Maritime Archaeology Project, which has been ongoing since 2007. The 450th Anniversary Shipwreck Survey, named in honor of St. Augustine’s 450th anniversary which occurred in 2015, was funded by a State of Florida, Division of Historical Resources Small Matching Grant (No. S1604).
Ground truthing, or testing previously identified targets, was one of the principal objectives of the 450th field season. The first site to undergo this ground truthing was a target that had originally been identified in 1995 by Southern Oceans Archaeological Research (SOAR) during the first purely research oriented marine magnetometer survey of the St. Augustine area.
The target was re-surveyed by the Lighthouse Archaeological Maritime Program (LAMP) in 2009 and designated as Hulk. It was selected for additional work in 2015.
Ground Truthing for Shipwrecks
First ground truthing efforts in 2015 yielded no results for this promising target so it was decided to acquire a new set of magnetic data. This target survey was done on July 15th and once contoured the data yielded a close but different location from which to begin ground truthing operations.
Dive operations began on July 16th, 2015 with a refined placement of the drop buoy by the first dive team. A twenty meter tape was centered on the target running east-west and the team began to test the transect with a hydro-probe, a galvanized steel pipe through which water is pumped at high pressure.
