Understanding ocean ecosystem services is essential for tackling the complex challenges our planet faces today. As oceans play a vital role in regulating climate, supporting biodiversity, and providing essential resources for human well-being, it is imperative to deepen our knowledge of how these ecosystems function and respond to anthropogenic pressures. Recent advances, such as improved methodologies for assessing marine biodiversity and the development of ecosystem service frameworks, have illuminated the intricate connections between ocean health and human prosperity. These insights are vital for informing policies that promote the conservation and sustainable use of oceans, seas, and marine resources.

Continued research in this area holds immense potential for transformative advances. Innovations in remote sensing technology and ecological modelling could lead to more effective management strategies for marine resources, enhancing our ability to tackle issues like overfishing and habitat degradation. Furthermore, interdisciplinary approaches that integrate social sciences with biological oceanography may yield new insights into the impacts of human behaviour on marine ecosystems, ultimately guiding efforts to achieve sustainable development. By fostering a deeper understanding of ocean ecosystem services, we can work towards a future where marine health and human well-being are inextricably linked.

The negative impact of micro- and nanoplastics on marine ecosystem health is a critical ecotoxicological problem of global concern, as these pollutants pose significant threats to biodiversity, ecosystem balance, ocean and human health. Continued research in this area enhances our knowledge of how these contaminants affect marine organisms and their habitats, leading to informed conservation strategies. Recent advances, such as improved field sampling, state-of-the-art detection methods and a better understanding of exposure pathways, including indirect and direct ingestion, and inhalation along with potential bioaccumulation in marine species and foodwebs, have provided essential insights into the extent of the problem. This includes emerging evidence of impacts on non-faunal organisms such as phytoplankton, algae, and microbial communities. Looking ahead, potential advancements could include the development of bioremediation technologies and innovation of more environmentally friendly and sustainable material substitutes designed to reduce plastic polymers production and mitigate plastic pollution.

By investigating the pervasive footprint and effects of micro- and nanoplastics on marine ecosystems, we contribute to a broader understanding of the implications for marine health, ultimately aiding in the preservation of marine biodiversity.

We invite researchers to contribute to this special Collection by submitting original research articles, reviews and methodology articles. Topics of interest include but are not limited to:

• Sources and exposure pathways of micro- and nanoplastics
