$500 billion question: What's the value of studying the ocean's biological carbon pump?

The ocean plays an invaluable role in capturing carbon dioxide (CO2) from the atmosphere, taking in somewhere between five to 12 gigatons (billion tons) annually. Due to limited research, scientists aren't sure exactly how ...

Great Barrier Reef 'glue' at risk from ocean acidification

The scaffolds that help hold together the world's tropical reefs are at risk from acidification due to increased carbon dioxide in the world's oceans, according to geoscientists at the University of Sydney.

Warmer, acidifying ocean brings extinction for reef-building corals, renewal for relatives

Changes in ocean chemistry and temperature have had a dramatic effect on the diversity of corals and sea anemones, according to a team of scientists who have traced their evolution through deep time. A new study, published ...

Ocean acidification causing coral 'osteoporosis' on iconic reefs

Scientists have long suspected that ocean acidification is affecting corals' ability to build their skeletons, but it has been challenging to isolate its effect from that of simultaneous warming ocean temperatures, which ...

Effects of nutrient pollution in marine ecosystems are compounded by human activity

Excessive nutrients, such as nitrogen and phosphorus, have devastating effects on coastal marine ecosystems by causing algal blooms that deplete oxygen in the water, killing marine life. Such nutrients can enter the sea in ...

Marine food webs under increasing stress

Scientists at the University of Adelaide have found growing evidence that marine ecosystems will not cope well with rising sea temperatures caused by climate change.

More carbon in the ocean can lead to smaller fish

As humans continue to send large quantities of carbon into the atmosphere, much of that carbon is absorbed by the ocean, and UConn researchers have found high CO2 concentrations in water can make fish grow smaller.

A surprising range of climate events may be predictable years in advance

An increase in the likelihood of a "Greenland Block"—a bulge of high pressure that stalls over the massive island and can cause extreme weather both in North America and Europe—could be predictable years in advance.

Climate change could make toxic algal blooms in our oceans more deadly

Late spring and early summer in California bring thousands of marine mammals to the state's beaches, as groups of California sea lions, elephant seals and harbor seals give birth along the shore. Visitors to places such as ...
