| Zusammenfassung |
| The deep sea is often viewed as a vast, dark, remote, and inhospitable
environment, yet the deep ocean and seafloor are crucial to our lives through
the services that they provide. Our understanding of how the deep sea
functions remains limited, but when treated synoptically, a diversity of
supporting, provisioning, regulating and cultural services becomes apparent.
The biological pump transports carbon from the atmosphere into deep-ocean
water masses that are separated over prolonged periods, reducing the impact
of anthropogenic carbon release. Microbial oxidation of methane keeps another
potent greenhouse gas out of the atmosphere while trapping carbon in
authigenic carbonates. Nutrient regeneration by all faunal size classes
provides the elements necessary for fueling surface productivity and
fisheries, and microbial processes detoxify a diversity of compounds. Each of
these processes occur on a very small scale, yet considering the vast area
over which they occur they become important for the global functioning of the
ocean. The deep sea also provides a wealth of resources, including fish
stocks, enormous bioprospecting potential, and elements and energy reserves
that are currently being extracted and will be increasingly important in the
near future. Society benefits from the intrigue and mystery, the strange life
forms, and the great unknown that has acted as a muse for inspiration and
imagination since near the beginning of civilization. While many functions
occur on the scale of microns to meters and timescales up to years, the
derived services that result are only useful after centuries of integrated
activity. This vast dark habitat, which covers the majority of the globe,
harbors processes that directly impact humans in a variety of ways; however,
the same traits that differentiate it from terrestrial or shallow marine
systems also result in a greater need for integrated spatial and temporal
understanding as it experiences increased use by society. In this manuscript
we aim to provide a foundation for informed conservation and management of
the deep sea by summarizing the important role of the deep sea in society. |
