Ocean Acidification destroying Antarctic marine life

Marine snails in seas around Antarctica are being

affected by ocean acidification, scientists have found.

An international team of researchers found that the snails' shells are being

corroded.

Experts says the findings are significant for predicting the future impact of

ocean acidification on marine life.

The results of the study are published in the journal Nature Geoscience.

The marine snails, called "pteropods", are an important link in the oceanic

food chain as well as a good indicator of ecosystem health.
 

"They are a major grazer of phytoplankton and... a key

prey item of a number of higher predators - larger plankton, fish, seabirds,

whales," said Dr Geraint Tarling, Head of Ocean Ecosystems at the British

Antarctic Survey (BAS) and co-author of the report.

The study was a combined project involving researchers from the BAS, the

National Oceanic and Atmospheric Administration (NOAA), the US Woods Hole

Oceanographic Institution and the University of East Anglia's school of

Environmental Sciences.

UN team examines mining threat to Great Barrier Reef

The Great Barrier Reef off the Queensland coast is home to a wealth of marine life

A UN team has arrived in Australia to investigate possible damage to the Great Barrier Reef by the mining industry.

Fears that coal exports and oil and gas exploration would jeopardise the reef prompted the Unesco delegation's visit.

Environmentalists have urged the government to suspend mining development until a government review is completed.

The reef is home to 400 types of coral and 1,500 species of fish.

The Great Barrier Reef, which holds Unesco World Heritage

status, lies off the coast of the state of Queensland, which is the

largest producer of coal in the country.

The Unesco team is scheduled to visit the reef for a week

before making recommendations to the World Heritage committee. They will

also meet members of the government.

Environmentalists are concerned that an increase in coal

production and the shipping traffic that would follow could affect the

Great Barrier Reef's World Heritage status.

They want the government to suspend all new developments

while a state and federal review of the health of the reef is carried

out.
