NOAA is examining potential disturbances to the health and well being of white sharks that could occur from research and tourism in Gulf of the Farallones National Marine Sanctuary over the next five years, because they may disrupt the natural behavior of white sharks.
The public has an opportunity to review and comment on a draft programmatic environmental assessment that evaluates a range of potential white shark research techniques that might be used in the sanctuary, including the use of tracking devices, decoys, chum and shark cages.
The assessment expands on a previous draft analysis from 2010 that looked at the effects of a research project which placed small satellite transmitters on white sharks. It also evaluates shark dive tourism operations that use artificial seal decoys to attract sharks.
White sharks depend on the rich waters of the sanctuary, and as apex predators play a key role in maintaining a balanced ecosystem. Each fall, adult and sub-adult white sharks frequent the waters of the sanctuary. Adult white sharks are seen most frequently in the area between Tomales Pt., Año Nuevo Island and the Farallon Islands, where elephant seals and sea lions are abundant. Research that could be permitted after the assessment may aid in our understanding of these sharks.
NOAA developed the assessment to help make informed decisions on the best options to protect and conserve the white shark population that feeds and congregates in the sanctuary.
NOAA will accept public comments on the draft programmatic environmental assessment through April 23. The sanctuary is interested in hearing from all interested parties, including permit holders, shark conservation groups, the wildlife viewing community and general public.
