Sediment cores the team collected by drilling in front of the current Cosgrove Ice Shelf indicate that relatively
warm ocean waters dissolved the vast ice shelf and even some of the glacier behind it about 2000 years ago, they recently reported.
Not exact matches
Due to the cooling
dissolved material now partially precipitates as fine particles, which are carried by the
warm water to the
ocean's surface.
The one - two punch of
warming waters and
ocean acidification is predisposing some marine animals to
dissolving quickly under conditions already occurring off the Northern California coast, according to a study from the University of California, Davis.
Because
warm water holds less oxygen than cold
water,
oceans are expected to lose some of the
dissolved gas as a consequence of climate change.
More CO2 can be
dissolved in cold
water than
warm water, and there are a number of carbon sequestering and releasing processes involving
ocean life.
Furthermore, in the absence of such
warming,
ocean mixing would normally be expected to be constantly refreshing the
water at the
ocean's surface, the place where it meets with air and
dissolves CO2.
About 40 percent of the carbon enter the
oceans through the
waters of the Southern
Ocean, around Antarctica, because CO2
dissolves more readily in cold seawater than in
warmer waters.
