Potential of ocean-based climate action

Authors: Jean-Pierre Gattuso, Phillip Williamson, Carlos Duarte and Alexandre Magnan Implementing the Paris Agreement is a formidable challenge. It requires far-reaching and unprecedented transitions in all sectors, and also large-scale use of negative emissions technologies (NETs), that is removal of greenhouse gases from the atmosphere by deliberate human activities. Beside mitigation, the ocean is also…

Continuous moulting by Antarctic krill drives major pulses of carbon export in the north Scotia Sea, Southern Ocean

Authors: C. Manno, S. Fielding, G. Stowasser, E.J. Murphy, S.E. Thorpe & G.A. Tarling Antarctic krill play an important role in biogeochemical cycles and can potentially generate high-particulate organic carbon (POC) fluxes to the deep ocean. They also have an unusual trait of moulting continuously throughout their life-cycle. The authors determine the krill seasonal contribution…

Five organizational features that enable successful interdisciplinary marine research

Authors: Jessica Blythe and Chris Cvitanovic The unique challenges presented by the Anthropocene to marine socio-ecological systems necessitate new approaches of knowledge production that are capable of integrating scientific disciplines to develop solutions that are desirable, equitable, and viable.  Despite increasing rhetorical support for interdisciplinary marine research, however, significant challenges associated with doing interdisciplinary research…

Deep Sea Research Part II: The Second International Indian Ocean Expedition (IIOE-2): Motivating New Exploration in a Poorly Understood Ocean Basin

The recently published Deep-Sea Research II special issue of scientific papers emanating from the Second International Indian Ocean Expedition (IIOE-2). It showcases a diverse body of contemporary Indian Ocean research and includes papers on physical, chemical and biological oceanography, and covers trophic levels from phytoplankton to whales. With this volume the IIOE-2 moves closer towards…

Anthropogenic impacts on nutrient variability in the lower Yellow River

From 2001 to 2018, the dissolved inorganic nitrogen (DIN), dissolved inorganic phosphorus (DIP) and dissolved silicon (DSi) concentrations showed decreasing trends in the Yellow River. These trends may have been influenced by the continuous promotion of protection polices and an increase in public environmental awareness. Extremely low nutrient concentration events were observed since 2014 in…

Trophic interactions will expand geographically but be less intense as oceans warm

Interactions between species are likely to change geographically due to climate‐driven species range shifts and in intensity due to physiological responses to increasing temperatures. Marine ectotherms experience temperatures closer to their upper thermal limits due to the paucity of temporary thermal refugia compared to those available to terrestrial organisms. Thermal limits of marine ectotherms also…

Trends in South Pacific fisheries management

While categorized as Small Island Developing States, South Pacific Island nations are the custodians of major ocean areas containing marine resources of high commercial and environmental significance. Yet, these resources are threatened by climate change, overfishing, Illegal, Unreported and Unregulated (IUU) fishing, as well as habitat destruction. The study, carried out in the early stage…
