What is ocean acidification?

Ocean acidification is the name given to the lowering of pH of the oceans as a result of increasing carbon dioxide (CO2) in the atmosphere. The pH of the ocean is determined by the level of hydrogen protons (H+) in sea water. The lower the pH, the more acidic the ocean. Read more about What is ocean acidification?

What impact did the Samoa tsunami have on New Zealand?

A powerful Magnitude 8.0 earthquake ruptured the seafloor south of Samoa on 30 September 2009, unleashing a destructive tsunami on Samoa, American Samoa, and northern Tonga (Niuatoputapu). Its impact on distant New Zealand shores was picked up by a sea-level monitoring system operated by NIWA and other agencies. The system showed that peak waves arrived between 1–2 and 13 hours after the arrival of the first tsunami waves, depending on locality.
