Seismic investigations in an area off western Norway showed that the acoustic abundance estimate for pelagic fish was higher outside than inside the seismic shooting area, indicating a long-term effect of the seismic activity (Slotte et al., 2004).
Effects of seismic shooting and vessel-generated noise on fish behaviour and catch rates.
Effects of seismic shooting on local abundance and catch rats of cod (Gadus morhua) and haddock (Melanogrammus aeglefinus).
Chevron is due to start seismic shooting
next week on acreage it acquired off the coast of Agadir, while drilling started in March at one of the three deepwater exploration blocks that BP farmed into.
The fibre-optic seismic system is part of a series of initiatives that Shell has undertaken to improve the quality of data obtained from seismic shooting
. Shell technologists recognised the potential breakthrough innovation of applying PGS' underlying OptoSeisTM technology for onshore seismic.
The removal of the previous political barriers enabled seismic shooting
from coast to coast across the Baltic Proper and free information exchange between Estonia and Sweden.
Depending on the permitting process, op de Weegh says that the earliest estimate for seismic shooting
in the Beaufort Sea will be the summer of 2006, and Shell will likely seek a joint venture partner for the project.
