Data collected from Southern Ocean phytoplankton laboratory culture experiments to examine the effect of iron limitation on the Chlorophyll fluorescence (F) to chlorophyll (Chl) ratio. Irradiance levels at which cultures were grown are indicated by the photon flux density (PFD). Growth rates of Fe limited cultures (-Fe) relative to Fe replete cultures (+Fe) are referred to as μ / μmax (unitless).

This record provides an overview of the NESP Marine and Coastal Hub scoping study - "Research needs for a national approach to socio-economic values of the marine environment". For specific data outputs from this project, please see child records associated with this metadata. -------------------- Effective management of natural resources and biodiversity requires an integrated understanding of the complex relationships between people and nature. This project reviewed a range of socio-ecological frameworks to identify which system components influence environmental outcomes, and which are most relevant for policy design and behaviour change. A key point of difference from previous NESP Marine Biodiversity Hub projects was an additional theme on implementation pathways, enabling research to inform the full progression from policy to on-ground action. Through a co-design process with stakeholders, the project identified priority social and economic research needs and assessed the availability of relevant datasets to meet them. A key outcome was the identification of three common decision contexts faced by managers—monitoring, trade-off analysis, and promoting behaviour change—and the matching of appropriate frameworks and data to each context. The findings highlight critical data gaps, while providing practical guidance on how existing information can be strategically used to inform management and policy decisions. Outputs • Inventory of compiled datasets relating to relevant economic values, threats, and socioeconomic values for Case Study locations [data inventory] • Four fact sheets, each based around common decision contexts encountered by the project [written] • Final Project Report [written]

This record provides an overview of the NESP Marine and Coastal Hub project "Evaluation of recreational fishing behaviour, use, values and motivations that relate to compliance". No data outputs were generated by this project. -------------------- Recreational fishing is an important leisure activity that brings economic and social benefits to the Australian community. Australia’s recreational sector is the largest and most widely dispersed recreational activity that uses a natural resource. Management strategies for this sector includes quotas, bag limits and no-take zones in marine reserves. Given the prohibitive cost of deploying compliance officers to monitor Australia’s vast marine estate, strategies are needed to encourage fishers to comply with zones of their own accord. This research focused on recreational fishers active in the Great Barrier Reef Marine Park (GBRMPA) waters, and in Geographe Marine Park and Two Rocks Marine Park off Western Australia. More than 800 online surveys were distributed to fishers, followed by focus groups and data analysis. These aimed to better understand how factors such as demographics, fishing patterns, and motivations related to individual or group intentions to comply with no-take zones. The survey findings informs on the use of behavioural change interventions to support regulation compliance of recreational fishers and boaters. It delivers a proof of concept tailoring of behaviour change to inform the practical design of interventions in case studies for further refinement, implementation and evaluation in subsequent research. Outputs • Fact sheet - characterising recreational fishing population [written] • Final project report [written]

Decision-makers seek to account for the socioeconomic values of environmental assets. However, understanding the available frameworks and data can be a barrier. We address this here by summarising the data used across four case studies (3 geographic regions and 3 socio-economic value frameworks) to demonstrate what data are available and how they are applied to support decisions in varied contexts. See 'Lineage' section of this record for additional methodology.

This record provides an overview of the NESP Marine and Coastal Hub Research Plan 2024 project "Unbroken whispers: the ripples connecting sea kin". For specific data outputs from this project, please see child records associated with this metadata. -------------------- Knowledge, in all its forms, is key to effectively protecting and recovering threatened and migratory whales and dolphins. Indigenous ecological knowledge (IEK) has guided Indigenous peoples through many uncertain climate and ecological fluctuations. IEK has also been used as part of protected area and species management for many thousands of years. More recently, IEK has shown huge potential to contribute to our understanding of threatened and migratory whales and dolphins, but this knowledge has not historically been collated, analysed or properly considered. Consequently, there is an absence of Indigenous perspectives and use of cultural knowledge informing the protection and recovery of EPBC listed threatened and migratory species. This Indigenous-led project will identify and share (where appropriate) cultural knowledge of relationships with whales and dolphins, and connections between land, sea and sky. Indigenous communities will participate in research that explores cultural ideology around kinship and responsibilities to kin, through expressing the knowledge, values and concerns they hold for whales and dolphins. The acquired knowledge and methods will support the cultural governance of sea Country by Indigenous communities and organisations, and policymaking, implementation and review by government agencies in relation to resource use and conservation. Outputs • GIS visualisation package of key geospatial layers related to connecting land and sea in the context of cultural keystone species [dataset] • Final project report [written]
