Sustainable seas

The Sustainable Seas National Science Challenge’s vision is for NZ to have healthy marine ecosystems that provide value for every New Zealander. Its research projects provide modern contexts for exploring all strands of the nature of science, including socio-scientific topics. These resources have been made in collaboration with scientists and communicators at the Sustainable Seas NSC.

Sustainable Seas Challenge EBM

Ecosystem-based management (EBM) - INFOGRAPHIC Developing ecosystem-based management (EBM) is at the core of the Sustainable Seas Challenge. EBM will help resource managers more effectively manage our marine resources and involve Māori, industry, communities and environmental groups in decision making.

Dynamic Seas — ARTICLE The seas surrounding New Zealand are complex. They are a connected and dynamic mix of chemical, physical and biological processes. The sheer size of the ocean and the complexity of interactions mean there is a lot we don’t know about marine environments. New Zealanders depend on and value the sea for kaimoana, aquaculture and fisheries, tourism, transport, recreation and spiritual wellbeing.

Looking at ecosystem-based management (EBM)

Ecosystem-based management - ARTICLE The Sustainable Seas National Science Challenge’s vision is for New Zealand to have healthy marine ecosystems providing value for every New Zealander. It has seven research themes, and each theme supports the development of a new way to manage our marine environment called ecosystem-based management (EBM).

Sustainable Seas national marine experiment

Sustainable Seas national marine experiment - VIDEO The Sustainable Seas National Science Challenge is conducting the country’s first national experiment of its kind. Professor Conrad Pilditch explains how scientists are collecting data on the interactive effects of increased turbidity (cloudy water due to sediments) and nutrients on coastal ecosystems. Why do you think that Conrad refers to marine ecosystems as hidden gardens?

Investigating marine and coastal tipping points

Investigating marine and coastal tipping points — RESOURCE As New Zealanders, we love our oceans. Coastal and offshore waters are our playgrounds and sustain us spiritually and economically. As a nation, we want this ecological relationship to continue – we want to have healthy ecosystems that provide the goods and services we have always enjoyed. However, competing uses of the marine environment,

Modelling marine stressors and tipping points

Modelling marine stressors - STUDENT ACTIVITY Simply defined, a tipping point is the point when a number of changes or incidents become significant enough to cause a large change in the way a system functions. The tipping point concept is used across many disciplines. When used in an ecological setting, scientists generally regard a tipping point as when an ecosystem moves from something of value to one less valued.

Identifying marine stressors

Identifying marine stressors - INTERACTIVE STUDENT ACTIVITY In this activity, students use online or paper resources to identify potential human-induced marine stressors. Students can then use this information to consider steps they can take as individuals or as part of the school or community to help reduce the stress.

For example, a loss of biodiversity due to overfishing. Note this is different to changes in states of matter.
