With the help
of Tim Collins, Ann Wettrich (video), and
Gary Rodgers
(boat captain) about 4 cubic yards/meters of ocean floor sediment
for the ship element was collected on September 25, 1993. The fishing
boat the "Seal"
was chartered for the collection. Sediment
collection area: Continental
Shelf, Pacific Ocean, depth:
17-25 fathoms (100-150 ft., 30-45 m.), distan
ce; 3-6 miles (5-10
km.) off the Central California coast, cross-hatched area on map
above left. Gradient,
a single channel video, color, 00:06: 00, 1994, documents the gathering
of
the sediment. A scrolling text over the video image lists potential
minerals from the erosion surfaces of the western Sierra Mountain,
Sacramento Valley and Coast Ranges carried out the Golden Gate
by the Sacramento River that might be found in the sediment. See "sediment
essay" link
below for mineral list. |
