NOAA research links human-caused CO2 emissions to dissolving sea snail shells off U.S. West Coast

NOAA research links human-caused CO2 emissions to dissolving sea snail shells off U.S. West Coast

For the first time, NOAA and partner scientists have connected the concentration of human-caused carbon dioxide in waters off the U.S. Pacific coast to the dissolving of shells of microscopic marine sea snails called pteropods.

West Coast prepares for ‘double whammy’ threat to ocean health

Rising levels of acidity in the ocean and growing areas of low-oxygen waters are a “double whammy” threat for fishing industries, ecosystems and economies along the U.S. West Coast and Canada’s British Columbia, according to new report by a panel of experts that includes NOAA scientists.

About Us

The Office of Oceanic and Atmospheric Research (OAR) - or "NOAA Research" - provides the research foundation for understanding the complex systems that support our planet. Working in partnership with other organizational units of the NOAA, a bureau of the Department of Commerce, NOAA Research enables better forecasts, earlier warnings for natural disasters, and a greater understanding of the Earth. Our role is to provide unbiased science to better manage the environment, nationally, and globally.
