NEW CARISSA MIDWAY TO FINAL RESTING PLACE
Waldport, Ore., March 9, 1999 1930 hours At 6:00 p.m. today, the tug Sea Victory was about 147 miles, or 127 nautical miles, west of Waldport. The Unified Command expects that by midnight Thursday, March 11, the tug and bow will reach the site where the bow will be sunk. The bow is listing about 10 degrees toward the starboard side, which may be caused by flooding. The vessel is currently over about 9,000 feet of water and, if it sinks due to this flooding, the tug is not in any danger because it can easily release the towline. A slight sheen from the bow was observed during this afternoon's overflight. It is small and unrecoverable and dissipated within about a half a mile of the vessel. Individuals who find oiled wildlife should call (541) 536-7614 to report the location and the amount of oil on the wildlife. The hard, or protective, boom was pulled out of Alsea Bay today. It is on standby and ready to be replaced if necessary. The bow of the New Carissa will be sunk in more than 9,000 feet of water at a site beyond the continental shelf. The ship will not be sunk near volcanic vents. There is no data on biological conditions at that specific site, but studies at similar depths give clues about what to expect. The area is dark and sluggish, meaning currents usually move at less than .05 knots, and the temperature is about 35 degrees. The amount of fish and benthic marine life, such as sea cucumbers and crabs, is much less than on the continental slope or shelf and there are no commercially important fish. Probably two to 10 times fewer organisms exist at the sinking site than on the continental shelf, and the density of benthic organisms is probably in the range of four to 10 organisms in 10 square meters. There may be some crustaceans, clams and worms in the sediment that are unique to that zone of the ocean. A study of a similar zone near San Francisco found an average density of 207 fish every two and a half acres. The New Carissa may smother some marine life when it hits bottom. In addition, the cloud of sediment created by the impact will slowly resettle around the ship, changing the environment of the creatures that live in the sediment within the area where the bow lands. The bow of the New Carissa will probably become an artificial reef for a variety of deep-sea fish and crabs. Since the oil will be a solid at those temperatures, it will probably not affect the marine life. |
