Conserve and sustainably use the oceans, seas and marine resources for sustainable development

This paper is particularly relevant to investigations into the spread of organisms that remain close to shore over timescales of days-to-weeks, e.g., the spread of marine non-native species and pathogenetic parasites, but is equally relevant to simulations tracking the dispersal of eDNA or coastal pollutants such as oil and plastics.
This paper develops a coupling between SWAN and Thetis models to account for wave–current interactions occurring by the co-existence of wave and current flows. The different grids and time-steps employed by the model components allow greater flexibility. The two models run consecutively, and communicate internally to exchange the necessary parameters. These are the significant wave height, mean wave direction, mean wavelength and percentage of wave-breaking calculated by SWAN necessary for calculating radiation stress and wave roller effects, while Thetis provides water elevation and current velocity fields.
This paper explores perceived barriers and enablers for engagement in a new aquaculture activity, using an example of ‘technology-push’ towards seaweed farming in coastal villages in Samoa.

Shows how practical economic levers can make the shipping industry more environmentally sustainable.
Monitoring the ocean carbon cycle is key to improved understanding. Satellites play a major role in our global carbon monitoring system. To make full use of satellite observations for ocean carbon monitoring the remote-sensing community needs to work closely with in-situ data experts, physical and biogeochemical modellers, Earth system scientists, climate scientists and marine policy experts.

Discusses international coordination and governance frameworks to protect the Arctic environment from damage from shipping.
A critical reflection on fisheries conservation in the Mekong River is offered here. Adaptive co-management helped balance conservation and livelihood outcomes. No-take zones facilitated basic fish conservation measures led by local fishermen. Fishermen perceiving livelihood benefits of conservation supported no-take zones. Long-term mechanisms to support community-led conservation initiatives are needed.
This study systematically evaluates the successful human stewardship in managing marine protected areas to provide useful lessons for future marine conservation actions.

This study provides a better understanding of the burrowing behaviour of the sub-legal size clams discarded on the sediment after being disturbed and contributes important data to improve practices for minimizing mortality of dislodged clams that are discarded on the sediment surface.
We are at a critical crossroads for the future governance of the high seas. We used the Nature Futures Framework to explore desirable futures for the high seas. Creative endeavours of co-production encourage imagination to address challenges. Participatory processes are important tools in the science-policy interface. Stories and art can be powerful ways to overcome barriers.
