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 investigate some of the properties of seawater. By the end of this activity, students should be able to: discuss that salt dissolves in water explain that dissolved ...
In this activity, students build their own food web using images of organisms from the marine ecosystem. This activity can be done indoors on paper or outdoors on a tarmac surface using chalk. By ...
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 ...
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 ...
Large snow events in most parts of New Zealand are uncommon. However, if you are in the South Island or the central North Island, this citizen science project could be a great one for your ...

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 ...
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 ...
This timeline lets you see the historical developments in technology related to weather monitoring, measuring and forecasting. It also shows how scientific thinking changed over the centuries as ...
This slideshow shows the process of sampling water and looks at the different microorganisms found.
