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 ...
Cold, oxygen-rich water from the Southern Ocean combined with a super-charged methane seep in the seafloor off New Zealand’s North Island have created a unique food web according to an ...
Limestone is an unusual rock in that it fizzes when dilute acid is placed on its surface. It is the presence of calcium carbonate that is responsible for this. The calcium carbonate content 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 ...

This citizen science project wants your assistance to extract information from various climate scientific graphics to help combat misinformation and support scientific communication. Using this ...
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 ...
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 ...
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 ...
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 ...
