The Ocean in Action
Diving into its chemical and physical processes
Meet New Zealand scientists studying the physical and chemical properties of the ocean, and explore the ocean’s role in transporting heat, water, salt and carbon around the Earth.

The Argo project has many scientific floats drifting around the ocean measuring currents, temperature and salinity down to a depth of 2000m. NIWA oceanographer Phil Sutton uses the real-time data in...
Ocean surface temperature varies with the amount of solar energy the water absorbs. Cold water is denser than warm so it sinks, causing deep water currents.
Seawater has many different gases dissolved in it, some of which are vital for living things. The uptake of carbon dioxide by the ocean regulates the gas in the atmosphere.
Dr Phil Sutton is an oceanographer with a physics background. He works for NIWA, where he is involved in the international Argo ocean studies project.
