It’s not an easy question to answer. In the lab, scientists can set up a series of seawater tanks with a variety of pH levels to figure out how different species react to more acidic water, observing...
Oceanographers divide the ocean into three broad zones. Together, they could hide 20 Washington Monuments stacked on top of each other. Each zone has a different mix of species adapted to its light...
