Oceans are becoming more acidic due to increased levels of carbon dioxide (CO2) in the atmosphere. Tiny marine animals called bryozoans may help monitor the impact of ocean acidification on the ...
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 interpret graphs from a long-term study of carbon dioxide in the atmosphere of New Zealand. They explore how the interval between samples affects the conclusions we are ...
In this activity, students observe the processes of evaporation and precipitation by creating a model that simulates the water cycle. By the end of this activity, students should be able to ...
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 ...
Come and visit Aotearoa New Zealand’s underwater world in this online citizen science project. Discover, count and identify unique fish species that live within our marine reserves ...
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 ...
Did you know that 80% of marine litter globally starts life on land? Mizuiku Upstream Battle is a citizen science programme run by Keep New Zealand Beautiful. It aims to get volunteers across ...
The rocky shore is a popular topic in primary school science. Below are some Science Learning Hub resources for primary teachers related to the rocky shore in the Living World strand of the New ...
About 70% of Earth’s surface is covered by water. It is found just about everywhere and is the only naturally occurring substance on Earth existing in solid, liquid and gas states. Water is ...
With 75% of New Zealanders living within 10 km of the coast, many students will be familiar with estuaries. In scientific terms, estuaries are the interface between the land and the sea – 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 ...
