The world's oceans are vitally important to all life on Earth. However, human activities are altering marine ecosystems in highly detrimental ways. To better protect our oceans, we need a greater understanding of how serious threats – overfishing, widespread pollution and global climate change – are altering these environments.
To improve our knowledge of ocean ecosystems and the life they support, the Ocean Science Division pursues a diverse portfolio of projects related to marine conservation. We develop and support scientific research, technical analyses and syntheses of scientific information that help to explain critical emerging issues, inform policy and advance solutions to conservation problems.
As part of our work, Pew funds the Sea Around Us Project at the University of British Columbia. The project has assembled global databases of fisheries information, including catches, prices, distribution of commercial marine species and marine protected areas. The project analyzes and maps data, documents the impact of fisheries, and devises recommendations to reverse harmful trends.

The sailfish—a type of marlin— is the fastest fish in the ocean. These fish move at an average speed of 40mph—that’s a whopping seven times faster than Olympic athletes swim. Read More
The population growth of any species depends on its life-history characteristics. With many of the world’s shark populations declining, it is important to examine how these characteristics differ from other fish to identify the most effective management approaches. Read More
This fact sheet presents estimates of total catches from 1950 to 2010, including recreational and traditional catch, which has been neglected in official accounting. Total catches appear relatively sustainable given the size of Australia’s ocean area, and discards have declined. Read More
