Keith Hunter is fascinated by the chemistry of the oceans and what we can learn. His research looks at trace metals in natural waters – minute amounts of metals, occurring in tiny quantities, but ...
Dr Kim Currie from NIWA studies carbon dioxide in the upper ocean around New Zealand. This helps her understand the role of the ocean in the carbon cycle and how the ocean and the atmosphere ...
Long-term studies show carbon dioxide levels in the atmosphere are rising. Radiocarbon carbon dioxide peaked in the 1960s but has since decreased. Much has been taken up by the ocean. Dr Kim ...
In this activity, students look at what happens when hot and cold water meet. By the end of this activity, students should be able to: discuss how temperature affects the density of water discuss ...
In this activity, students build simple models to demonstrate the differing impacts of melting land ice and sea ice on sea level rise. Rights: The University of Waikato Te Whare Wānanga o Waikato ...
Cold water is denser than warm water, so it tends to sink. Seawater is denser than freshwater. Salinity, temperature and depth all affect the density of seawater. The ocean has a complex ...
Help scientists establish valuable baseline data about the numbers, locations, habits and health of penguins in a range of Southern Ocean sites. This information will enable better understanding ...
Kelp forests are one of the most biodiverse habitats on Earth. Every nook and cranny is jam-packed with life! This citizen science project wants to understand more about how kelp forests grow and ...
By comparing some features of fossilised plants with the same features of plants living today, scientists hope to be able to learn more about the effect of changing carbon dioxide (CO2) levels in ...
There are many marine classroom activities and resources on the Science Learning Hub useful for Seaweek 2015. This online PD session recorded on 19 February 2015 shows primary and secondary ...
Seaweek is New Zealand’s annual national week about the sea. It is coordinated by the Sir Peter Blake Marine Education and Recreation Centre (MERC) and includes a wide range of events ...
Do you need resources for Seaweek? Are you planning a science unit on the sea? In this online PD session recorded on 18 February 2016, PD provider and teacher Barb Ryan explores some of the ...
Our oceans are absorbing about one-third of the carbon dioxide in the atmosphere. As a result, they are becoming more acidic. Associate Professor Abby Smith, from the University of Otago, is ...
Dr Sara Mikaloff-Fletcher, an atmospheric modeller at NIWA, explains how the level of carbon dioxide in the atmosphere has been rising in recent times. She outlines some of the sources for this ...
NIWA scientists collect air samples from an atmospheric research station at Baring Head on Wellington's south coast. What's in the air that we breathe?
Water in the Earth system is influencing all aspects of life on Earth. Pathways, storage, transfers and transformations have an effect on the global climate and human welfare. Within this ...
