Relationship between Ozone and Oceans

The relationships between the ozone layer and climate are interesting,

and poorly understood. Here's an interesting article which describes

one such link:

Ozone hole weakens oceanic carbon sink

 

 

A new model links stratospheric ozone depletion to ocean acidification.

The hole in the ozone layer over Antarctica may be impairing the

Southern Ocean's ability to mop up carbon dioxide from Earth's

atmosphere, according to work presented at a meeting in France today.

 

Earth's oceans are the largest sink of carbon dioxide, with the

Southern Ocean accounting for more than 40% of the annual oceanic

uptake of the greenhouse gas, says Andrew Lenton, a marine biochemist

at the Pierre and Marie Curie University in Paris. In theory, seas

should soak up more carbon dioxide as levels of the gas in the

atmosphere rise.

 

But recent measurements have bucked simulations1—3 and shown that the

Southern Ocean's surface waters have higher carbon levels than

expected, which also makes them more acidic. As a result, the amount

of CO2 that the ocean absorbs each year has also flattened out.
