Ocean acidification evolves on the background of a natural ocean pH gradient that is the result of the interplay between ocean mixing, biological production and remineralization, calcium carbonate cycling, and temperature and pressure changes across the water column. While previous studies have analyzed these processes and their impacts on ocean

Exoskeleton dissolution with mechanoreceptor damage in larval Dungeness crab related to severity of present-day ocean acidification vertical gradients
Highlights • Coastal habitats with the steepest ocean acidification gradients are most detrimental for larval Dungeness crabs. • Severe carapace dissolution was observed in larval Dungeness crabs along the US west coast. • Mechanoreceptors with important sensory and behavioral functions were destabilized. • Dissolution is negatively related to the growth,
Transcriptomic response to decreased pH in adult, larval and juvenile red king crab, Paralithodes camtschaticus, and interactive effects of pH and temperature on juveniles
Ocean warming and acidification are expected to influence the biology of the ecologically and economically important red king crab, Paralithodes camtschaticus. We investigated transcriptome responses of adult, larval and juvenile red king crab to assess sensitivity to reduced pH and elevated temperature. In adults, gill tissue (but not heart or
Dungeness crab larvae already showing effects of coastal acidification

California coastal waters rising in acidity at alarming rate, study finds
A commercial fishing boat heads out of Morro Bay. A study released Monday found that waters off the California coast are acidifying faster than the rest of the ocean. (Al Seib / Los Angeles Times) Waters off the California coast are acidifying twice as fast as the global average,
