500-year-old clams recorded changes in ocean climate

“Perhaps best known as an essential ingredient in clam chowder, the longest living animal, the quahog clam, has another important use: providing information about changes in ocean climate. Growth rings on the clams’ shells reveal changes in seawater temperature and salinity over the last 100 years that are unprecedented for the last millennium. Lead author David Reynolds tells us more about the study.”


This is incredible, the ocean is such a vast space that we haven’t really discovered.
