October 9, 2009 - The sightings of 10-20 great white sharks off Chatham this past summer had some locals thnking that a warming Atlantic Ocean might have been a factor. Now comes a report in the journal Global Change Biology. University of British Columbia researchers used a computer model to analyze data on 1,066 fish species ranging from sharks to shrimplike creatures at the bottom of the food chain.
