| In 1993, the Institute of
Nautical Archaeology (INA) at Texas A&M
University
located the remains of an ancient stone carrier
wrecked off the Aegean coast of Turkey at Kizilburun, a rocky promontory southwest of
Izmir
(ancient Smyrna) and east of the Greek
of
Chios. The wreck Transport
amphoras from
East Greece, the
Adriatic and even Egypt
suggest a date in the first quarter of the 1st
century BC.
The site lies in 45 – 48m
water depth and by 2006 covered an area approximately 40m x 20m with
flat
sand on rock terraces. Diving
time is limited because of the depth to two 20 minute dives each
day. |
| The image below shows part of the site plan
from the 2006 excavation in Site Recorder 4. The plan shows artefact
positions, artefact detail drawings and survey control points overlaid on
top of a sketch showing areas of reef and a small photomosaic of the
remaining six drums. |

| The site was recorded using a combination of
trilateration and 3D photogrammetry. A network of survey control
points was installed around the site, some fixed into bedrock and others
were temporary tripod frames. The relative positions of the control
points was determined by trilateration and using relative depth
measurements. Photogrammetry was used to extract detail point
positions for finds, photographs of the site taken with digital cameras
were processed using PhotoModeler, using the network of survey points to
tie groups of points together in to the main site coordinate
frame. PhotoModeler is a powerful 3d software product that calculates measurements and constructs 3d models from your photographs simply and easily.
The next image shows the area to the north of drums 1
and 2 that had already been excavated. The finds drawings shown in
the plan are of the finds that had been recovered although a few (such as
block ABW) were still in-situ. |

This picture shows the control point
network set up around the drums and the set of distance measurements used
to position the points, the relative position accuracy was computed by Site
Recorder to be 20mm. |
