ATAMU/INA PROJECT

QUESTIONS TO BE CONSIDEREDQUESTIONS TO BE CONSIDERED 1. How was the site found? 2. How was the site excavated? 3. What was found? 4. How were questions answered? ---- Keeping in mind that any excavation of an

underwater site is going to be more complicated than expected, more expensive than expected, and the analysis will go on much longer than expected and require the assistance of a number of different specialists!

Port Royal, JAMAICA

Largest English town in the New World when it sank in an earthquake on

June 7, 1692.

The only submerged town in the New World

Located at the tip of a 18 mile long sand spit makes for a precarious location subject to the whims of

nature.

The Institute of Nautical Archaeology spent 10 years excavating on the 17th-century, submerged remains of Port Royal. More than 150 students worked on the site.

Some sites such as the

sunken town of

Port Royal are so well-known they are never

lost. There is an

abundance of historic documents and maps.

Taylor’s 1688 map of Port Royal.

Of course the significant thing about Port Royal, is that much of it sunk into Kingston Harbor during an

earthquake on June 7, 1692, ca. 11:40 A.M.

In Historical Archaeology the documents and even the frozen

hands of a recovered watches reveal details on everyday life in

Port Royal in the late 17th Century.

August 1692

Barge ActivityBarge Activity

The shallow diving is conducted from a support barge and is

done during 3 hour or longer dives using HOOKA.

Land view of dredges used to excavate.

In shallow water, all excavations are done with a water dredge that control the

direction of the exhaust across the bottom through a hose

Air Lifts such as used in earlier excavations are not effective in

shallow water for they dump the

sediments on top of your head, destroying all

visibility

All Catastrophic sites are characterized by the great abundance of well-preserved artifacts - pipes, pewter, porcelain, bottles!

-- housing a Cobbler, a Tavern and

Mapping in Poor Visibility

Errors always creep in and accumulate, but modern science has provided

instrumentations that allow us to overcome some of the difficulties.

The difficulties of plotting the building and artifacts were facilitated by SHARPS - Sonic High Accuracy Ranging and Positioning System.

The excavations of Building 4/5

revealed a first -- a building rammed by a ship during the earthquake!

Built in two stages. Bldg. 4 was tacked

on to it. Note the pattern of hearths and

sharing of cisterns.

was excavated..

Artifact AnalysisArtifact Analysis

With the 10 year excavation completed, the detailed analyses of

the thousands of recovered artifacts is

started

Pewter, because of the presence of maker’s marks and ownership marks are particularly useful for identifying

occupants of building. Pewter is seldom found on land sites
