This project developed multimedia resources that can be used to explore what EBM for Aotearoa New Zealand looks like now, and how it could look in the future.

Tipping points in ecosystem structure, function and services

We investigated how marine ecosystems respond to change, and identified tipping points, risks and ways of managing them.

Ecosystem models

We developed simulation models for the Tasman and Golden Bays marine ecosystem to test what is likely to happen in different scenarios.

Participatory tools

We are developing web-based tools to enable New Zealanders to interact with and use knowledge generated by our research.

Enabling inter-agency collaboration on cumulative effects

We produced guiding principles to help decision-makers manage the cumulative effects of human activities and natural events on the marine environment.

Participatory processes for marine ecosystem restoration

We examined how the Kaituna River re-diversion strategy was developed, to identify success factors in stakeholder and iwi engagement that could be applied in other marine resource contexts.

Navigating marine social-ecological systems

We aimed to identify and/or improve our understanding of institutional, social and cultural factors that need to be incorporated into EBM for it to be successfully used to manage Aotearoa New Zealand’s marine resources.

Development of valuation frameworks and principles

We identified frameworks and principles for recognising the multiple values of the marine environment to support EBM.

What could EBM look like in Tasman and Golden Bays?

We are investigating how to successfully put EBM into practice in Aotearoa New Zealand’s marine environment.

EBM within Aotearoa New Zealand’s existing legislative framework

We investigated how well EBM aligns with Aotearoa New Zealand’s legislation, policy and governance relating to the marine environment.

Incorporation of indigenous approaches to guardianship in Canada

We evaluated how indigenous approaches have been incorporated into Canada’s marine resource management policies.

Defining marine habitat use by seabirds

We investigated whether a range of different mathematical models accurately reflect seasonal seabird distributions in Aotearoa New Zealand waters.

Novel risk assessment tools for EBM

We are reviewing new methods to help assess and manage risks to Aotearoa New Zealand’s marine ecosystems.

Spatially-explicit decision support tools

We developed tools to help decision-makers explore how best to use and share marine spaces.

Estimating historic effects from sedimentation and fishing

We are investigating how historical and contemporary changes to sedimentation and bottom contact fishing may influence fisheries in Tasman Bay.

Quantifying marine biodiversity using environmental DNA

We have developed an innovative way to detect species in the sea using environmental DNA (eDNA) extracted from water samples.

Sediment tolerance and mortality thresholds of benthic habitats

We investigated the effects that suspended sediment from human activities has on the health and survival of deep water species in the South Taranaki Bight.

Submarine canyons: connecting coastal and deep-sea ecosystems

We investigated how well submarine canyons transport materials from the land into deeper waters surrounding Aotearoa New Zealand.

Stressor footprints and dynamics

We investigated how coastal waters and oceans mix and transport materials that can stress marine ecosystems.

Ecosystem connectivity: tracking biochemical fluxes to inform EBM

We traced the fate of water and sediments from land through coastal food webs, evaluating connections between coastal and deep sea habitats, and identified the effects of key coastal developments (such as aquaculture) on food web connectivity.

Whaia te Mana Māori Whakahaere Tōtika ki Tangaroa – in pursuit of Māori governance jurisdiction models over marine resources

We explored and developed innovative governance tools for the marine environment while enhancing relationships between Māori, the Government and industry.
