Portland
Photomosaic Project
During
three days in September 2004 the sanctuary, in conjunction with
the National
Undersea Research Center
at the University of Connecticut (NURC-UCONN), returned to
the steamship Portland to continue the site documentation
begun in 2002. Project personnel used the NURC/UCONN remotely
operated vehicle (ROV) Hela to gather digital still and video
imagery of the shipwreck. Hela was equipped with a 3 CCD digital
video camera, a 3 megapixel digital still camera with strobe,
and a HMI light. Operations were conducted off the University
of Connecticut vessel R/V Connecticut, which made day trips
out of Gloucester, MA.
The ROV Hela outfitted with a downward facing camera
to capture video for a mosaic of the Portland's main deck.

The
investigation focused on photographing the Portland's
main deck as part of an ongoing project to assess, study,
and interpret the shipwreck for the public. This project
obtained digital video imagery of the Portland from
its bow to just aft of the port paddlewheel including the
boiler uptakes and walking beam engine. Additional video
imagery of the steam release pipe along with undientified
wreckage to the port side of the Portland's bow was
also recorded. Plan view digital still and video images
were taken of the Portland's steam release pipe as
well as 70% coverage of the main/freight deck level forward
of the boiler uptakes. Video and still images will be used
to create a mosaic of the site and associated features.
