An international team from the Nippon Foundation-University of British Columbia Nereus program has unveiled the first global model of life in the world's oceans, allowing scientists and policymakers to predict and show through 3D visualizations the state of life in the oceans of the future.
Combining scientific data from three major factors impacting our oceans climate change, human activity (including fisheries and river run-off) and food web dynamics (fish eating fish), the Nereus model shows life under the sea from 1960 to 2060. Based on current policies, the model shows a strong decline in the biomass of large fish, while some small fish may actually be increasing.
"Our preliminary results show a global fish biomass of two billion tonnes, confirming earlier estimates taken from regional modeling," says UBC Fisheries Prof. Villy Christensen, who is presenting the research today at the Annual Meeting of the American Association for the Advancement of Science (AAAS) in Vancouver, Canada.
"This is the first comprehensive attempt to model life in our global oceans, and will require refining, but we can now show the future impact of choices we are making today, and answer the question: what must we do now to leave healthy oceans and fish to future generations?"
NB: Prof. Christensen is available for embargoed interviews 8:30-10 a.m. and 12-6 p.m. Friday, Feb 17 at 604-562-1151 (cell) or firstname.lastname@example.org.
Christensen's academic symposium, titled Predicting the Future Ocean: The Nereus Program is at 8:30-11:30 a.m. Saturday, Feb 18, Vancouver Convention Centre room 217/218.
He is participating in a AAAS news briefing at 12 p.m. Saturday, Feb. 18 at Vancouver Convention Centre Room 223-224.
