The 8^th IMBeR China-Japan-Korea (CJK) Symposium was held at the East China Normal University in Shanghai, China last month. The theme was Marine Biogeochemical Sciences for the Sustainability of the West Pacific Biosphere. In addition to participants from China, Japan and Korea, the symposium attracted researchers and students from Thailand, India, Pakistan, Sri Lanka, Malaysia and Canada.

Following the symposium, the IMBeR Human Dimensions Working Group held a training course. These meetings are held every second year and the next one will be in Thailand in 2020.

Although ecosystem services are increasingly embedded in policy agendas, it is largely unknown if and how policy actors are considering them. This paper features a retrospective analysis of interviews with key policy actors involved in the strategic decision-making process leading to an innovative large-scale Dutch coastal management project, the Sand Motor mega beach nourishment. The interviews were analysed to ascertain which ecosystem services were considered and how they were described by policy actors. The findings suggest that broad, unspecified ecosystem services were adopted highly by the policy actors, while specific ecosystem service categories were rarely considered. Also, relatable and easy to understand cultural ecosystem services also constituted critical arguments for policy actors in their strategic decision making. The study suggests a ‘translation step’ between ecosystem services research and decision making for ecosystem services to truly align with relevant aspects of decision making.

We are now accepting abstracts for Future Oceans₂. We welcome abstracts for oral and poster presentations. Abstracts must be submitted for specific sessions or workshops, and so it is advised to consult the session and workshop details prior to submission. The deadline for abstract submission is 1^st December 2018. Abstracts must be submitted via the registration and abstract submission portal. There is no fee for abstract submission. 

IMBeR´s regional programme, CLIOTOP’s largest Task Team ‘Marine Predator Isotopes’ recently published an article in Global Ecology and Biogeography. The paper presents a global spatial and comparative analysis of nitrogen stable isotopes for three species of tuna: yellowfin, albacore and bigeye. Predictive models were employed to assess broad-scale spatial patterns and environmental drivers of oceanic food webs. The analyses highlighted that while there are regional differences in the trophic structure of oceanic ecosystems, globally, tunas share similar functional trophic roles. Their work suggests that habitat compression resulting from the predicted global expansion of oxygen minimum zones with ocean warming will impact marine food webs and the corresponding foraging habits of marine predators.

The sixth IMBeR ClimEco summer school was held at the Universitas Gadjah Mada in Yogyakarta, Indonesia last month. It brought together 60 participants and lecturers from a range of natural, social and economic marine science disciplines, to consider Transdisciplinary approaches for sustainable oceans.
