The ocean covers a vast region of the planet and is often thought of as remote and poorly known. However, more than a century of research has made it clear that the ocean provides many beneficial and critical services to society, including a diversity of society–ocean interactions beyond what humans extract (or may extract) from it. The deep sea is no different; it provides a wealth of societal benefits that span the spectrum from inspiring art and captivating the mind to mitigating the rate of climate change through its connectedness with the Earth’s ecosystems. These processes and societal impacts fall within the broad category of ‘nonuse’ ecosystem services, or societal benefits that occur in addition to, or instead of, the services realised through resource extraction. Much like the surface ocean, while there is much more to discover, there is a significant body of information about the deep sea that has resolutely identified this environment as an important resource for nonuse benefits. In this chapter we give an overview of the nonuse services that are provided by the deep ocean, identify some of the advances to date on incorporating these values into the discussion of the natural capital of the deep, and highlight the challenges and opportunities that face incorporation of nonuse values into management-decision processes.

Healthy oceans are essential to maintain a healthy planet, but the ocean is facing many challenges that need urgent attention. Robust scientific data and innovative technological, policy, and industrial solutions are essential to support sound management of the deep-ocean natural capital, both within and beyond national jurisdiction, to ensure future healthy and productive oceans. As with many systems on Earth, there is a delicate ecological balance in the deep ocean that must be maintained. Understanding the interactions of the different components of natural capital in the deep sea is complex, as many of the variables are interlinked and many have cumulative and synergistic effects on the ecosystem. Add to this the global and changing effects of climate change and ocean acidification, and legislators and managers have a tough job ahead to account for all of these issues when designing appropriate conservation measures. It is important that scientists work hand in hand with multiple stakeholders to identify issues and research needs that contribute to enhancing knowledge and the science needed for decision-making to help towards securing a healthy future for our deep-ocean ecosystems and their long-term natural capital.

<p><strong>Traditionally, deep-sea ecosystems have been considered to be insulated from the effects of modern climate change. Yet, with the recognition of the importance of food supply from the surface ocean and deep-sea currents to sustaining these systems, the potential for rapid response of benthic systems to climate change is gaining increasing attention. North Atlantic benthic responses to past climate change have been well-documented using marine sediment cores on glacial-interglacial timescales, and ocean sediments have also begun to reveal that planktic species assemblages are already being influenced by global warming. However, very few ecological time-series exist for the deep ocean covering the Holocene-through-industrial era. Here, we use benthic and planktic foraminifera found in Northeast Atlantic (EN539-MC16-A/B and RAPID-17-5P), Northwest Atlantic (KNR158-4-10MC and KNR158-4-9GGC) and Labrador Sea (RAPID-35-25B and RAPID-35-14P) sediments to show that, in locations beneath areas of major North Atlantic surface water change, benthic ecosystems have also changed significantly over the industrial era relative to the Holocene. We find that the response of the benthos is dependent on changes in the surface ocean near to the study sites. Our work highlights the spatial heterogeneity of these benthic ecosystem changes and therefore the need for local-regional scale modelling and observations to better understand responses to deep-sea circulation changes and modern surface climate change. </strong></p>

Traditionally, deep-sea ecosystems have been considered to be insulated from the effects of modern climate change, but with the recognition of the importance of food supply from the surface ocean and deep-sea currents to sustaining these systems, the potential for rapid response of benthic systems to climate change is gaining increasing attention. However, very few ecological time-series exist for the deep ocean covering the twentieth century. Benthic responses to past climate change have been well-documented using marine sediment cores on glacial-interglacial timescales, and ocean sediments have also begun to reveal that planktic species assemblages are already being influenced by global warming. Here, we use benthic foraminifera found in mid-latitude and subpolar North Atlantic sediment cores to show that, in locations beneath areas of major surface water change, benthic ecosystems have also changed significantly over the last ∼150 years. The maximum benthic response occurs in areas which have seen large changes in surface circulation, temperature, and/or productivity. We infer that the observed surface-deep ocean coupling is due to changes in the supply of organic matter exported from the surface ocean and delivered to the seafloor. The local-to-regional scale nature of these changes highlights that accurate projections of changes in deep-sea ecosystems will require (1) increased spatial coverage of deep-sea proxy records, and (2) models capable of adequately resolving these relatively small-scale oceanographic features.

The greater than 109 km3 volume of the deep-sea water column and greater than 300 × 106 km2 area of the deep-sea floor represent a major natural capital asset. Global society has been utilising space in the deep ocean as a reservoir for solid, liquid, and hazardous waste produced by terrestrial-based societies, as a buffer that absorbs nonsolid, nonliquid industrial waste streams, specifically CO2 from fossil fuel and biomass burning, heat from a warming atmosphere, and as freely available and convenient space. High-value uses such as the deployment of transoceanic telecommunications cables provide substantial, near-term economic and societal returns with minimal environmental impact. Low-value uses of this natural capital as empty space to absorb waste have arguably enabled industrialisation to continue further along an unsustainable trajectory than would have occurred had there been no such waste buffer available.

There has never been a time like the present when there is so much media, scientific, and economic interest in the deep waters of the world ocean and the animals that live there. It is increasingly important for students and new researchers, as well as experienced scientists, to understand how their research can help to address pressing societal challenges. It is beneficial for deep-sea scientists, social scientists, lawyers, authorities, conservationists, industry, and civil society to have broad knowledge of the issues surrounding exploitation in the deep ocean, which has gradually become an increasingly important research focus. The current and future work of deep-sea scientists in all disciplines provides rigorous scientific data and knowledge to support sound management of human activities in this highly complex and variable realm. In this volume, we have brought together internationally recognised scientists, economists, and legal experts to describe the processes by which humans can benefit from the natural capital of the deep sea in a sustainable framework. For this to happen, communication between all deep-sea stakeholders is essential, and this volume aims to facilitate future discussions between the many different sectors of society who may influence the global deep ocean for future generations.


The deep ocean is, by far, the planet’s largest biome and holds a wealth of potential natural assets. Most of the ocean lies beyond national jurisdiction and hence is the responsibility of us all. Human exploitation of the deep ocean is rapidly increasing, becoming more visible to many through the popular media. The scientific literature of deep-sea exploitation and its actual and potential effects has also rapidly expanded as a direct function of this increased national and global interest in deep-sea resources, both biological (e.g. fisheries, genetic resources) and non-biological (e.g. minerals, oil, gas, methane hydrate). At the same time there is a growing interest in deep-sea contamination (including plastics), with many such studies featured in high-profile scientific journals and covered by global media outlets. Finally, climate change is affecting even the deepest regions of our oceans and is a major priority for the international scientific and political agendas. However, there is currently no comprehensive integration of information about resource extraction, pollution and effects of climate change and these topics are only superficially covered in classic textbooks on deep-sea biology. The human race is at a pivotal point in potentially benefitting from the deep ocean’s natural resources and this concise and accessible work provides an account of past explorations and exploitations of the deep ocean, a present understanding of its natural capital and how this may be exploited sustainably for the benefit of humankind whilst maintaining its ecological integrity. The book gives a comprehensive account of geological and physical processes, ecology and biology, exploitation, management, and conservation.

Emotion is a core feature of the human condition, with profound consequences for health, wealth, and wellbeing. Over the past quarter-century, improved methods for manipulating and measuring different features of emotion have yielded steady advances in our scientific understanding emotional states, traits, and disorders. Yet, it is clear that most of the work remains undone. Here, we highlight key challenges facing the field of affective sciences. Addressing these challenges will provide critical opportunities not just for understanding the mind, but also for increasing the impact of the affective sciences on public health and well-being.

In the context of considering natural capital in decision-making, the ecosystem services concept is steadily increasing in importance. This also holds for the forest sector in Germany. This development calls for a harmonisation of approaches and terms used in the forest sector, as well as being made compatible with the ecosystem services concept and relevant classifications. In Germany, and a number of Central European countries, a common way to assess the multifunctional benefits of forests is the forest function mapping method. Due to the federal multi-level governance system in Germany, each state has its own classification of forest functions and mapping. A first objective of this paper is to align the various forest function categories across German states as a basis to relate them to the ecosystem services concept. Second, this bottom-up approach is combined with a top-down approach, building on the Common International Classification of Ecosystem Services (CICES). The aim is to develop a harmonised, methodological framework, suitable for accounting forest-related ecosystem services, as a step towards future ecosystem services monitoring and reporting commitments in the forest sector. Finally, the challenges and opportunities of the ecosystem services concept for forest management are discussed and ways forward are elaborated.

AbstractMarine sinking particles transport carbon from the surface and bury it in deep sea sediments where it can be sequestered on geologic time scales. The combination of the surface ocean food web that produces these particles and the particle-associated microbial community that degrades these particles, creates a complex set of variables that control organic matter cycling. We use targeted metabolomics to characterize a suite of small biomolecules, or metabolites, in sinking particles and compare their metabolite composition to that of the suspended particles in the euphotic zone from which they are likely derived. These samples were collected in the South Atlantic subtropical gyre, as well as in the equatorial Atlantic region and the Amazon River plume. The composition of targeted metabolites in the sinking particles was relatively similar throughout the transect, despite the distinct oceanic regions in which they were generated. Metabolites possibly derived from the degradation of nucleic acids and lipids, such as xanthine and glycine betaine, were an increased mole fraction of the targeted metabolites in the sinking particles relative to surface suspended particles, while algal-derived metabolites like the osmolyte dimethylsulfoniopropionate were a smaller fraction of the observed metabolites on the sinking particles. These compositional changes are shaped both by the removal of metabolites associated with detritus delivered from the surface ocean and by production of metabolites by the sinking particle-associated microbial communities. Further, they provide a basis for examining the types and quantities of metabolites that may be delivered to the deep sea by sinking particles.
