Update from the Field: Advanced Technology Combs North Sea for Bonhomme Richard!

Wednesday, September 15, 2010 12:07 PM

 NHHC Underwater Archaeology Branch Head, Dr. Robert Neyland, reports from USNS Henson that the survey for Bonhomme Richard is going smoothly. Dr. Neyland, along with partners from Ocean Technology Foundation, Naval Meteorology and Oceanography Command, Naval Oceanographic Office, Office of Naval Research, and U.S. Naval Academy, is on schedule and has already completed about 45% of the survey using a towed side scan sonar and two Autonomous Underwater Vehicles (AUV). The Naval Surface Warfare Center (NSWC) is utilizing an Office of Naval Research Autonomous Underwater Vehicle (ONR AUV) to help the researchers interpret likely shipwreck targets through the gathering of site specific remote sensing data through the combined collection of sonar, magnetic variations, and photography. The surveyors reported having found a number of shipwreck-like targets on the ocean floor that will have to undergo further future investigation. Bonhomme Richard, after 230 years on the sea bottom, is expected to have the appearance on sonar of a debris field of ballast, cannon, and other objects. It may appear as a sediment-covered mound rather than an easily recognizable sailing ship. Hence many of the sites found will have to undergo further investigation by divers and Remotely Operated Vehicles (ROVs). Weather permitting, the survey will be completed over the next few days.

Phase 1 of SCORPION Project Complete!

SCORPION Project barge transported back down the Patuxent after the completion of the field work.

 On August 12, the NHHC Underwater Archaeology Branch (UAB), and its partners MD SHA and MHT, successfully completed the first phase of their three-year archaeological investigation of the Patuxent shipwreck believed to be the War of 1812 U.S. block sloop SCORPION. Firstly, a big thank you to our on-site visitors who made the trip out to Upper Marlboro, MD. It was great to see you and we really appreciate your support! We were also glad to welcome members of the press on site to inform them about the SCORPION project, our partnerships and the NHHC and were pleased to see the story covered in the Washington Post, Baltimore Sun and The Capital (Annapolis)

 During the first part of the two-week project, UAB’s team of underwater archaeologists, in cooperation with MD SHA and MHT, measured the site and extent of the wreck beneath the sediment via a process called “hydroprobing.” Based on the data from the hydroprobe, the team was then able to determine which parts of the wreck most warranted investigation. Archaeologists then removed the overburden (overlying sediment) from specific parts of the wreck using dredge systems; the sediment pulled from the wreck was suctioned up the dredge onto the barges where it was screened by capable staff. Some artifacts were also recovered and brought back to the UAB Conservation and Archaeology Lab for stabilization, treatment and documentation.

Again, the UA team is very grateful to MD SHA and MHT as well as URS and SUPSALV. With their help and cooperation, significant progress was made during Phase 1 and we look forward to working with them again on the next phase of the SCORPION project in summer 2011. We’re always glad to talk about the SCORPION project and answer any questions, so feel free to stop by our offices or send us an email (NHHCUnderwaterArchaeology@navy.mil) and stay tuned for more posts!

UAB initiates USS SCORPION Project!

On July 19, the NHHC Underwater Archaeology Branch (UAB) along with partners from the Maryland State Historical Trust and the Maryland State Highways Administration, initiated the first phase of a three-year archeological investigation of the shipwreck site believed to be USS SCORPION. SCORPION was the flagship of Commodore Joshua Barney’s Chesapeake Bay Flotilla, which he ordered to be scuttled and burned in the Patuxent River to prevent its capture by the British during the War of 1812. The UAB team, led by Dr. Robert Neyland, in collaboration with SUPSALV, will spend two weeks in the field to complete a survey, limited excavation, and documentation of the site. UAB’s underwater archaeologists will carefully dredge overburden to reveal the structure of the ship, and then map the site and any artifacts uncovered in the process. Artifacts recovered will be catalogued and transported to the UAB Archaeology & Conservation Laboratory for stabilization and treatment.

 Stay tuned for more project updates next week!
