“…A number of studies have, however, considered Southern Ocean ecosystem services using a range of approaches. These include an attempt to catalogue the main services at the circumpolar scale (Grant et al, 2013b), regional assessments (Deininger et al, 2016;Neumann et al, 2019) and studies considering the potential effects of change (Murphy et al, 2016;Rogers et al, 2020;Trebilco et al, 2020). However, at present, although it is evident that the Southern Ocean provides globally important ecosystem services, information is sparse on their current status, and how they may change into the future.…”

The Southern Ocean supports ecosystem services that are important on a global scale. Climate change and human activities (tourism, fishing, and research) will affect both the demand for, and the provision of, these services into the future. Here we synthesize recent assessments of the current status and expected future climate-driven changes in Southern Ocean ecosystems and evaluate the potential consequences of these changes for the provision of ecosystem services. We explore in detail three key services (the ‘blue carbon’ pathway, the Antarctic krill fishery, and Antarctic tourism), tracing the consequences of climate change from physical drivers through biological impacts to the benefits to humans. We consider potential non-climatic drivers of change, current and future demands for the services, and the main global and regional policy frameworks that could be used to manage risks to the provision of these services in a changing climate. We also develop a formal representation of the network of interactions between the suite of potential drivers and the suite of services, providing a framework to capture the complexity of this network and its embedded feedback loops. Increased consideration of the linkages and feedbacks between drivers and ecosystem services will be required to underpin robust management responses into the future.

“…This predominance is due to a steadily increasing knowledge on biochemical processes within single cells, often subsumed under the term 'adaptation', and a shift from qualitative to quantitative ecosystem-level analyses. It is still challenging to link these two extremes by up-and downscaling approaches to assess the variability and sensitivity of ecological functions (Gutt et al, 2018;Neumann et al (2019). Figure 1 shows that our 10 messages affect humans most in their connection with climate regulation, followed by nature conservation and to a lesser extent with human food provision and bioprospecting, including for medicine and lifestyle products and applications (Fig.…”

“…For instance, younger Inuit are trained to recognize a variety of ice types, each with their unique features, as well as the different risks associated with the seasons, such as being able to identify thin ice or ice edges that may break off (ICC- Canada, 2008). Inuit have also been witnessing changes in sea-ice dynamics over the past decades as related to climate change (Analok et al, 2001;Nickels et al, 2005). Inuit Qaujimajatuqangit (Inuit knowledge) provides a wealth of information to help understand ongoing and future changes, and the interweaving of Inuit knowledge with academic science can lead to more comprehensive assessments of climatic changes (Laidler, 2006).…”

“…They applied sea-ice coverage as a key factor for the analyses in their study and showed that the heterogeneity of the marine area of the Weddell Sea, especially related to variations in sea-ice cover, has a great impact on ecosystem services. Neumann et al (2019) evaluated the ES supply for the western Antarctic Peninsula region and also included sea ice as a key service provider, and Rogers et al (2020) and Cavanagh et al (2021) in their review on ES of the Southern Ocean highlighted sea ice as an environmental factor with a high likelihood to change and medium to high impact on marine communities or species. Eicken et al (2009) first introduced the concept of seaice system services, which categorizes the way stakeholders and rights holders perceive, measure, and use sea ice.…”

A rigorous synthesis of the sea-ice ecosystem and linked ecosystem services highlights that the sea-ice ecosystem supports all 4 ecosystem service categories, that sea-ice ecosystems meet the criteria for ecologically or biologically significant marine areas, that global emissions driving climate change are directly linked to the demise of sea-ice ecosystems and its ecosystem services, and that the sea-ice ecosystem deserves specific attention in the evaluation of marine protected area planning. The synthesis outlines (1) supporting services, provided in form of habitat, including feeding grounds and nurseries for microbes, meiofauna, fish, birds and mammals (particularly the key species Arctic cod, Boreogadus saida, and Antarctic krill, Euphausia superba, which are tightly linked to the sea-ice ecosystem and transfer carbon from sea-ice primary producers to higher trophic level fish, mammal species and humans); (2) provisioning services through harvesting and medicinal and genetic resources; (3) cultural services through Indigenous and local knowledge systems, cultural identity and spirituality, and via cultural activities, tourism and research; (4) (climate) regulating services through light regulation, the production of biogenic aerosols, halogen oxidation and the release or uptake of greenhouse gases, for example, carbon dioxide. The ongoing changes in the polar regions have strong impacts on sea-ice ecosystems and associated ecosystem services. While the response of sea-ice–associated primary production to environmental change is regionally variable, the effect on ice-associated mammals and birds is predominantly negative, subsequently impacting human harvesting and cultural services in both polar regions. Conservation can help protect some species and functions. However, the key mitigation measure that can slow the transition to a strictly seasonal ice cover in the Arctic Ocean, reduce the overall loss of sea-ice habitats from the ocean, and thus preserve the unique ecosystem services provided by sea ice and their contributions to human well-being is a reduction in carbon emissions.
