New tools for action on ocean health

Dawn Wright

How can people set goals for taking care of a system as large as the world's oceans? How is it even possible to know what is needed to keep oceans healthy and productive? The Ocean Health Index establishes a new world standard for measuring how people benefit from, interact with, and affect marine ecosystems, expressed as one number. Dawn Wright (2011) and her colleagues at the Environmental Systems Research Institute are working with Conservation International, Radical Media, and the University of California at Santa Barbara on methods for representing information from the index through maps on the web that will make detailed information easily available to people in every country of the world.

New measure of ocean health for nature and humans

When measuring ocean health, both nature and people need to be treated as integrated parts of marine systems. To this end, Scott Doney (2004) and Rashid Sumaila (2009) helped create a comprehensive index to assess the benefits of healthy oceans to humans. While most ecosystem assessments focus on the negative impacts of humans on nature, this index considers people as a major part of the solution, and seeks to offer a better system for thinking about how to manage the ocean. Doney hopes that it "will get people to think about tradeoffs and establish a healthy dialog about the future of the ocean."

Changing Arctic Ocean - surprising discovery under ice

Kevin Arrigo

A research team led by Kevin Arrigo (2009) has discovered a massive algal bloom under the Arctic pack ice, which scientists previously thought would be impossible due to lack of light. The study shows that the light reaching the upper water through the ice has been increasing because of thinning ice cover and the rapid growth of melt ponds in the Arctic Ocean. These conditions have enabled the algal blooms to form. The team hopes that this finding helps predict the impacts of ongoing and future changes in the Arctic Ocean environment.

Four Leopold Leadership Fellows part of national effort on ocean acidification

Scott Doney (2004), Victoria Fabry (2009), Gretchen Hofmann (2009), and Joanie Kleypas (2008) are part of a new committee that will recommend a national plan to research, monitor, and assess ocean acidification. The four Leopold Leadership Fellows were named by the National Research Council in April to the committee, which will recommend priorities for research that will increase understanding of how ocean acidification takes place and reduce uncertainty in projections on the rate of change and the effects on ocean ecosystems.
