Purpose
|
|
Locate sunken vessel Pac Baroness using side scan
|
|
sonar. Examine the vessel with the Recon IV ROV System, and determine overall
|
|
damage for potential discharges of copper ore and oil. Photograph and video tape
|
|
the wreck, surrounding sediments and biota, using the ROV System. Collect
|
|
sediment and water samples within 200 m of the wreck. Trawl for animal specimens
|
|
for body burden analysis of trace metals (especially copper) and possibly
|
|
hydrocarbons.
|
|
|
Summary
|
|
The sunken vessel was located through the use of side scan sonar and
|
|
the ship's fathometer. Equipment failures precluded additional attempts to
|
|
inspect the vessel with the ROV. The ROV obtained some environmental samples and
|
|
some video footage of ambient sediments and biota was obtained within about 500
|
|
to 250 m to the NW of the vessel. 16 water samples were collected from four
|
|
different locations within 300 m of the wreck via bottles attached to the ROV. A
|
|
small grab sample of sediment was collected within a 150-m range of the vessel.
|
|
No tissue samples were collected.
