NOAA and partners team up to prevent future Great Lakes drinking water crisis
Video of Preventing a Great Lakes Drinking Water Crisis A new video SMART BUOYS: Preventing a Great Lakes Drinking Water Crisis released by Ocean Conservancy describes how NOAA forecast models provide advance warnings to Lake Erie drinking water plant managers to avoid shutdowns due to poor water quality. An inter-agency team of public and private…

The Seafloor Is Dissolving Because of Climate Change
Carbon emissions are acidifying the ocean so quickly that the seafloor is disintegrating. According to a new study, ocean acidification is setting off a dangerous feedback loop that’s dissolving the very bottom of the ocean. According to a study published this week in PNAS, this sets off a feedback loop that acidifies the ocean even…

West Coast Ocean Acidification Rates Among Highest In World
The United States is stepping away from the Paris Climate Agreement, but the consequences of climate change will be more difficult to leave behind. Take ocean acidification, a major emerging threat to West Coast fisheries. Researchers at Oregon State University have recorded some of the highest levels of ocean acidification in the world – and…

Persistent spatial structuring of coastal ocean acidification in the California Current System
Across the CCLME, we observed near-shore pH that fell well below current global mean surface ocean pH of 8.1 (Fig. 1). Minimum pH reached as low as 7.43 at the most acidified site, and up to 18% of recorded values fell below 7.8 during the upwelling season (Table S1). These minima are among the lowest…

Acidified Ocean Water Widespread Along North American West Coast

(Credit: Jane Lubchenco) A three-year survey of the California Current System along the West Coast of the United States found persistent, highly acidified water throughout this ecologically critical nearshore habitat, with “hotspots” of pH measurements as low as any oceanic surface waters in the world. (From Phys.org /…
