Our Changing World for 22 April 2021
In this week's retrospective, Alison Ballance revisits an ocean acidification special feature called The Acid Test. Audio
Ocean acidification and the threat to coral reefs
Threats posed to Pacific Island countries by the rapidly increasing acidification of the world's oceans have been discussed at a workshop in New Zealand. Audio
Growing concern over rising acidity levels in seawater
New Zealand's waters are becoming more acidic due to the absorption of carbon emissions. It's not an issue confined to NZ - the world's oceans are experiencing the fastest rate of acidic change in 25… Audio
Fishing industry must adapt to warming ocean - NIWA
A leading marine scientist says New Zealand's commercial fishing industry might have to adapt, or risk decline as ocean temperatures warm. Professor Cliff Law of the National Institute of Water and… Audio
Paua, mussels and kina at risk
Paua, mussels and kina are at risk from increase in acid levels in the ocean and serious action is needed, scientists say. Higher acid levels can stunt growth and weaken the shells of kina, paua and… Audio
Acid test for coastal seas
The ocean is becoming more acidic, and this change is most pronounced in coastal seas. Marine scientists have received $4.9 million to work out what is going on and how this affects marine life along… Audio
Scientists look for link between ocean and clouds
A team of international scientists are setting sail for the Chatham Rise next week to try and discover how tiny organisms on the surface of the sea might help create clouds. Audio
The Acid Test - a Feature on Ocean Acidification
Increasing carbon dioxide is making the world's oceans more acidic; what does this mean for marine life? Audio
Mysterious satellite swirls identified as plankton
Scientists from the National Institute of Water and amp; Atmospheric Research have identified the source of spectacular satellite images that were captured by NASA over the weekend in New Zealand… Audio
Iron Fertilisation
NIWA scientists discuss adding iron to the ocean as a way of triggering algal blooms and the uptake of carbon. Audio
Science story
The science behind iron fertilisation and whether it really does offer a way of dealing with rising global carbon dioxide levels. Audio
Ocean Acidification
As the world's oceans become more acidic, what will be the impact on phytoplankton and seaweeds? Audio
