Underwater Archaeology and STEM Programming

Thursday, May 17, 2012 2:04 PM


The U.S. is currently prioritizing their public education agenda to focus on Science, Technology, Engineering, and Mathematics (STEM) subjects. The Naval History and Heritage Command (NHHC) and its Underwater Archaeology Branch (UAB) have created a pilot program to highlight aspects of the underwater archaeology field in order to complement STEM initiatives. The purpose of this Underwater Archaeology STEM Program Pilot Project is to expand the reach and influence of both the NHHC and the history and archaeology career field, and educational opportunities associated with underwater archeological science and technology. Archaeologists from the NHHC’s UAB and educators for the National Museum… Read the rest of this entry »

H.L. Hunley Fully Visible for the First Time

Wednesday, January 11, 2012 11:06 AM


On February 17, 1864, Confederate-built H.L. Hunley became the world’s first successful combat submarine when it attacked and sank the 1240-short ton screw sloop USS Housatonic at the entrance to the harbor of Charleston, South Carolina. H.L. Hunley surfaced briefly to signal a successful mission to comrades on shore with a blue magnesium light, after which it was never seen again. All eight of its crewmen were presumed lost and despite multiple search efforts, the submarine could not be relocated.  Over 136 years later, on 8 August, 2000, H.L. Hunley was raised from the sea floor using a specially-designed support frame, or truss. A multi-disciplinary team,… Read the rest of this entry »

Innovative Scientific Analysis Tool at Underwater Archaeology Conservation Lab

Monday, October 17, 2011 1:54 PM


NHHC volunteer, Dr. Raymond Hayes, Professor Emeritus at Howard University, Washington DC, and Woods Hole Biological Laboratory, Woods Hole, MA, has partnered with the Underwater Archaeology & Conservation Laboratory (UACL) to analyze archaeological materials from historic naval shipwrecks. Dr. Hayes has been awarded a Research & Discovery Grant from Olympus INNOV-X to examine archaeological components from shipwrecks using an innovative Delta portable X-Ray Fluorescence (pXRF) unit. This state-of-the-art technology uses an x-ray beam to identify the specific elements present within archaeological material. Dr. Hayes’ research endeavors to use this data to trace the elemental composition of a wood sample back… Read the rest of this entry »

USS SCORPION Project 2011: Final Week

Friday, August 12, 2011 4:08 PM


1 August, 2011 –  This begins the final week of excavation on the 2011 USS Scorpion Project! The team will work together this week to continue to investigate the wreck, map the site and recover artifacts. The team was pleased to welcome 7 staff members on site from NHHC Commemorations  and gave them a tour of the barges and explained the details of the archaeological operation.     2 August, 2011- Today, the archaeology team recovered two important pieces of the ship’s architecture which they believe to be “catheads.” Wooden vessels commonly had a pair of these thick, L-shaped beams incorporated into either side of the bow (one portside, one starboardside). One… Read the rest of this entry »

USS SCORPION Project 2011 Day by Day: Week Three

Thursday, July 28, 2011 11:05 AM


     Monday, 18 July 2011- Today, we were back in the Patuxent trenches continuing our efforts to delineate the boundaries of the suspected USS Scorpion wreck. So far, the team has been successful in uncovering ship timbers in test units placed on the upstream and downstream extremities of the site. These test units allow archaeologists to assess the vessel’s degree of preservation, articulation, and orientation within the river. One of the vessel’s features that we are still trying to determine is which end of the wreck is the bow and which end is the stern. Since Scorpion and the… Read the rest of this entry »

On the Hunt for Bonhomme Richard!

Tuesday, July 19, 2011 3:39 PM


On July 17th, the NHHC Underwater Archaeology Branch (UAB) along with partners from Ocean Technology Foundation, Naval Oceanographic Office, SUPSALV, Mobile Diving and Salvage Unit (MSDU) 2 and the US Naval Academy, set out to continue the search for one of the Navy’s first fighting vessels, Bonhomme Richard. Captained by the father of our Navy, John Paul Jones, the ship was lost in 1779 after engaging in combat with HMS Serapis off the Yorkshire coast of England. Although Jones emerged victorious, Bonhomme Richard was irreparably damaged. After transferring all men and supplies safely to the captured Serapis, Jones set the… Read the rest of this entry »

USS SCORPION Project: Phase II Begins!

Monday, June 27, 2011 9:41 AM


  After months of careful planning and preparation, the NHHC Underwater Archaeology Branch (UAB), in conjunction with Maryland Historical Trust (MHT) and the Maryland State Highway Administration (MSHA), initiated the second phase of the archaeological investigation of what is believed to be the wreck of USS Scorpion. Captained by US Navy hero Joshua Barney, Scorpion served as flagship in the famous Chesapeake Bay Flotilla, which endeavored to defend Washington, D.C. from the British during the War of 1812. On August 21st, 1814, British forces chased the Flotilla up a narrow bend of the Patuxent River where Barney then evacuated his… Read the rest of this entry »

UAB Loans MAC Lab a piece of Civil War History

Monday, November 29, 2010 5:05 PM


This morning, UAB welcomed members of the Maryland Archaeology Conservation (MAC) Laboratory team for the transport of a Civil War iron cannon. The 3-ton cannon was made in Liverpool, U.K. in 1862 and served aboard Confederate commerce raider CSS Alabama until she was sunk in 1864 by USS Kearsarge. The cannon was recovered from the shipwreck in 2002 and conserved at Texas A&M University’s Conservation Research Laboratory (CRL). It will be displayed under a UAB Loan Agreement in the MAC Lab facility at Jefferson Patterson Park & Museum in St. Leonard, MD until 2015, with the possibility of renewing the… Read the rest of this entry »
