Scientists believe oysters in San Diego Bay may help in protecting against coastal erosion. Here’s all you need to know.
How can oysters help save the coast?
Artificial reefs placed in water for reducing damage in southern California are home to tiny mollusks. In December 2021, they built over 306 structures along a peninsula between the salt marshes in Southern California and the Coronado peninsula. Coronado peninsula is the home to the naval aviation facility, the inspiration behind “Top Gun.”
“We look at numerous different ways to help combat sea-level rise, and these reef balls are one of the tools in our toolbox to do that,” stated Eileen Maher. Maher is the director of environmental conservation at the San Diego port.
Weighing 300 pounds, they resemble gigantic thimbles. The hemispheres are constructed out of sand, cement, and crushed oyster shells. The shells are a vital component that is causing the oysters to build a home here. Dr. Maher revealed that thousands of oysters are hidden due to greenish silt that accumulated on the reefs. Scientists engaged in the experiment want to see the development of oyster reefs. They believe it is going to have a real effect on this ecosystem.
More on the study
As per a National Oceanic and Atmospheric Administration (NOAA) report, sea levels around California are going to rise by eight inches by 2050. As a result, the west coast will experience increased floods. Additionally, human-caused climate change will also increase the chances of heavy rainfall and storms. Hence, scientists believe this could be more than a solution as a natural defense against tidal erosion. Bivalves inhabiting the reefs help in the creation of small ‘filtration plants’ and are a vital part of marine ecology.
