«Ocean acidification» (OA), a
change in seawater chemistry driven by increased uptake of atmospheric CO2 by the oceans, has probably been the most - studied single topic in marine science in recent times.
Now, marine scientists are wondering whether a dramatic, global
shift in seawater chemistry could make some deep - sea hermit crabs bolder — or rather, more foolhardy.
This change
in seawater chemistry alters the way sound moves through the ocean, allowing it to propagate farther, particularly for sounds two and a half octaves above «middle C,» said researcher Keith Hester of the Monterey Bay Aquarium Research Institute in California.
«Those results,» Fabry says, «suggest that for subpolar and polar pteropods to survive, they will need either to adapt to the expected
changes in seawater chemistry or to move to warmer, lower - latitude surface waters.»
This is because ocean acidification represents a series of changes
in seawater chemistry, with each alteration representing a potential driver of change [10].
