Cold seeps are places on the seafloor where cold hydrocarbon-rich water escapes. They occur most often at tectonic plate boundaries. Carbonate deposits and communities of organisms are often ...
Water contains atoms of oxygen and hydrogen, and life on Earth would not have evolved without it. Fruit and vegetables are made of 80% water, and our bodies are 60–70% water. (We lose about 2.5 ...
Calcium carbonate is the principal mineral component of limestone. Its chemical and physical properties lie behind the modern-day uses of limestone as well as the unique limestone landscapes of ...
In this activity, students construct models that resemble rain falling on a hillside to observe factors affecting soil erosion and ground stability. By the end of this activity, students should ...
In this activity, students view the interactive Calcination – lime from limestone, which shows the industrial processing of limestone into lime, and use the information to complete a matching ...
In this activity, students investigate some of the physical, chemical and physiological properties of carbon dioxide gas. In addition, a model demonstrating the amount of carbon dioxide in the ...

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 ...
In this recorded professional learning session, Lyn Rogers and guest Aliki Weststrate from GNS Science explore some of the science involved in building our understandings of natural hazards ...
Dr Ashley Rowden, a principal scientist with the NIWA Marine Benthic Ecology group based in Wellington, explains what cold seeps are, where they are located in New Zealand and why rich ...
Dr Steve Hood explains that a cold seep is the expulsion of hydrocarbon-rich fluids at the seafloor. Over time. a specialist type of limestone can form. These are quite unlike shelf limestones ...
NIWA's Dr Ashley Rowden describes how a community of organisms develops around a cold-seep site. Forming the base of such a community are specialised bacteria that use methane gas present in the ...
