"> Mixing and dilution controls on marine CO2 removal using alkalinity enhancement In the human body, dialysis is used to remove waste, a process that helps to reduce acidity in the blood. Scientists are using a similar process to withdraw seawater, remove acid, and return the high alkalinity water to the ocean. Ocean alkalinity enhancement is being […]

"> Salish Sea Model tracks pollution, currents and climate change
This article is the latest in a series about computer models and their uses within the Puget Sound ecosystem. Today, we look at the Salish Sea Model, one of several models in the region helping to predict water circulation, water quality and food-web relationships. Read the full series: Where and how the water moves The […]

"> PSI launches Salish Sea Modeling Center
The Puget Sound Institute is launching a new program that will use supercomputers to advance ecosystem recovery of the Salish Sea. The Salish Sea Modeling Center will allow scientists from around the region to access sophisticated computer models to predict changes in the ecosystem. Work at the center will tackle vexing environmental problems such as […]

"> New report describes anticipated climate-change effects in Washington state
Early effects of a warming Earth have reached Washington state, as we can see from actual measurements. Annual snowpack is declining in the mountains; ancient glaciers are shrinking; sea levels are rising; and coastal waters are becoming less hospitable to sea life. These are some of the changes outlined in a new easy-to-read briefing report […]

"> Sharing info, as changes in ocean chemistry affect Northwest waters at alarming pace
It was fairly alarming, even to scientists, to hear the latest research regarding ocean acidification — a powerful change in ocean chemistry that results from excess carbon dioxide passing from the atmosphere into the oceans of the world. One of the most alarming reports came from Richard Feely, senior scientist at NOAA’s Pacific Marine Environmental […]

"> Rate of ocean acidification may accelerate, scientists warn
Last summer, scientists met at the University of Washington to address alarming findings concerning the rapid acidification of the world’s oceans. Experts at that symposium warned that wildlife in the Salish Sea, from salmon to shellfish, may start to see significant effects from changing water chemistry within the next 10 to 20 years. PSI senior […]

"> Ocean acidification may be twice as extreme in Puget Sound’s seagrass habitats, threatening Dungeness crabs
Ocean acidification could be up to twice as severe in fragile seagrass habitats as it is in the open ocean, according to a study published last month in the Proceedings of the National Academy of Sciences. The conditions may threaten Dungeness crabs by 2050 and will be especially pronounced in the winter, the study says. […]

Local actions highlight ocean acidification report
By Christopher Dunagan, Puget Sound Institute The dangers of ocean acidification — an intrinsic feature of climate change — are coming early to Washington state, causing measurable harm to sea life, according to a new report that outlines a state strategy for pushing back against the problem. The report, titled “Ocean Acidification: from knowledge to […]
