A new study has revealed that waters off the coast of California are acidifying at double the pace of other oceans in the world. This can be quite troubling for the West Coast seafood industry as California coast accounts for nearly 10 percent of the United States’ haul of seafood. The research says that climate change has hastened the chemical changes in the ocean. Experts have observed the progress of ocean acidification in the present-day ecosystem of California through the 20th century. This ecosystem expands from southern British Columbia in Canada to Baja California in Mexico. Experts have claimed that rapid acidification of the ocean can be defined as coastal upwelling, which is an oceanographic occurrence. During the coastal upwelling, the deepwater comes on to surface along with the wind. The deepwater of the sea is more acidic and they worsen the acidification by human-flooded carbon dioxide in the atmosphere.
High levels of acid in the waters of the ocean mean that it has relatively fewer carbonate ions. Oysters, clams, corals, plankton rely on carbonate ions to form shells. If these creatures die while struggling with acidic water, it will have a threatening effect on salmon, whale and other predators across the food chain. Oceans play an important role in the planet’s carbon cycle. They are crucial reservoirs of carbon, which absorb carbon dioxide from the atmosphere. As per the study, global warming is distressing oceans’ ability to absorb carbon from the ecosystem. Although oceans can withstand the natural deviation in climate but human-filled carbon dioxide is grueling the sea around the world. As per the records, around 27 percent of total carbon dioxide emission has been absorbed by the oceans since 1959. Oceans get more acidic with rapid absorption of carbon into it. Oceans have become 30 percent more acidic after the industrial revolution has blown up in the world
Acidic seawater is more dangerous for those underwater species that form shells. Researchers have observed almost 200 fossilized shells from the last 100 years. They have found out that there has been a 20 percent reduction in the shells created by foraminifera. Foraminifera is a tiny group of organisms found in the ocean. Emily Osborne, the lead author of the study has said that she has seen shells getting thinner as she has moved up with the records and got closer to the present day. The new study has been published in the Journal Nature Geosciences. There are many questions on fore that how long California will be able to deal with more acidic underwater in its coastal areas.
