Most of us rely on the weather forecast to choose our outfit or make outdoor plans for the weekend. But conditions underwater can also be useful to know in advance, especially if you’re an oyster farmer, a fisher or even a recreational diver.
A new University of Washington computer model can predict conditions in Puget Sound and off the coast of Washington three days into the future. 

For people who make their living connected to nature, a favorable environment is critical. For farmers, that means having enough rain to bring a crop to harvest. For ski resort operators, that means having enough snow for a robust ski season. For commercial fishermen, that means having seasonal ocean temperatures that favor the fish they need for market.
The same goes for shellfish growers in Washington, who rely on the Northwest’s historically favorable marine waters to help produce delectable invertebrates, like clams and oysters. 

The productive ocean off Washington state’s Olympic Coast supports an abundant web of life including kelp forests, fish, shellfish, seabirds and marine mammals. The harvest and use of these treaty-protected marine resources have been central to the local tribes’ livelihoods, food security and cultural practices for thousands of years. But ocean acidification is changing the chemistry of these waters, putting many coastal species – and the human communities that depend upon them – under threat. 

On the heels of the United Nations Conference on Sustainable Development – otherwise known as Rio +20 – the UN established development goals centered around people, planet and prosperity. Among these is Goal 14, aimed at the conservation and sustainable use of the oceans, seas and marine resources. The goal calls out addressing the impacts of climate change and ocean acidification, among others. 

Irakli Loladze is a mathematician by training, but he was in a biology lab when he encountered the puzzle that would change his life. It was in 1998, and Loladze was studying for his Ph.D. at Arizona State University. Against a backdrop of glass containers glowing with bright green algae, a biologist told Loladze and a half-dozen other graduate students that scientists had discovered something mysterious about zooplankton. 

Acidification of the world’s oceans could drive a cascading loss of biodiversity in some marine habitats, according to research published Nov. 21 in Nature Climate Change.
The work by biodiversity researchers from the University of British Columbia, the University of Washington and colleagues in the U.S., Europe, Australia, Japan and China, combines dozens of existing studies to paint a more nuanced picture of the impact of ocean acidification.
