The goal of this paper is to review current impacts of human activities on the deep-sea floor ecosystem, and to predict anthropogenic changes to this ecosystem by the year 2025. The deep-sea floor ecosystem is one of the largest on the planet, covering roughly 60% of the Earth's solid surface. Despite this vast size, our knowledge of the deep sea is poor relative to other marine ecosystems, and future human threats are difficult to predict. Low productivity, low physical energy, low biological… Expand
The deep sea: The new frontier for ecological restoration
Abstract Deep-sea ecosystems are the most extensive on Earth and provide key goods and services for human well-being, such as genetic resources and climate regulation. Maintaining the sustainableExpand
Influence of Water Masses on the Biodiversity and Biogeography of Deep-Sea Benthic Ecosystems in the North Atlantic
Circulation patterns in the North Atlantic Ocean have changed and re-organized multiple times over millions of years, influencing the biodiversity, distribution, and connectivity patterns of deep-seaExpand
Man and the Last Great Wilderness: Human Impact on the Deep Sea
TLDR
The analysis shows how the most significant anthropogenic activities that affect the deep sea have evolved from mainly disposal to exploitation and predicts that from now and into the future, increases in atmospheric CO2 and facets of climate change will have the most impact on deep-sea habitats and their fauna.

Development Trend of Deep-Sea Ecosystem and Marine Protected Areas
The types, current situation, main problems, and technological needs of deep-sea ecosystems are described in this paper. Compared with those of shallow-sea ecosystems, samples of deep-sea ecosystemsExpand
Temporal change in deep-sea benthic ecosystems: a review of the evidence from recent time-series studies.
TLDR
The evidence for long-term changes both in biologically driven, sedimented, deep-sea ecosystems (e.g. abyssal plains) and in chemosynthetic ecosystems that are partially geologically driven, such as hydrothermal vents and cold seeps is assessed. Expand
Shedding Light on Deep-Sea Biodiversity—A Highly Vulnerable Habitat in the Face of Anthropogenic Change
The deep sea is the most extensive habitat on our planet, and it supports surprisingly high biodiversity. With a multitude of different environments and conditions previously thought to beExpand
Environmental Change in the Deep Ocean
Patterns of abundance, biomass, and species richness are reviewed for deep-sea ecosystems. Long-term monitoring studies have indicated that deep-sea ecosystems are sensitive to climatic variabilityExpand
Deep-water longline fishing has reduced impact on Vulnerable Marine Ecosystems
TLDR
It is demonstrated that deep-sea bottom longline fishing has little impact on vulnerable marine ecosystems, reducing bycatch of cold-water corals and limiting additional damage to benthic communities, and suggested that regulated deep-SEA longlining can be an alternative to deep- sea bottom trawling. Expand
Exponential Decline of Deep-Sea Ecosystem Functioning Linked to Benthic Biodiversity Loss
TLDR
This study provides scientific evidence that the conservation of deep-sea biodiversity is a priority for a sustainable functioning of the worlds' oceans and suggests that mutually positive functional interactions can be common in the largest biome of the authors' biosphere. Expand

A riot of species in an environmental calm: the paradox of the species-rich deep-sea floor
TLDR
Understanding of diversity patterns in the deep-sea benthos has increased dramatically in the last three decades, and evidence to date suggests that small-scale habitat variability and patchy disturbance, as well as global and regional variability, may play roles in maintainingDeep-sea diversity.

Deep-sea macrofaunal impacts of a large-scale physical disturbance experiment in the Southeast Pacific
TLDR
The DISCOL experiment did not fully simulate full-scale industrial impacts, but it has provided insights into macrofaunal recolonization following large-scale disturbance of deep-sea environments, and the reestablishment of a semi-liquid surface sediment layer is proposed as a potentially controlling factor for the re establishment of the macrofaunaal community after physical disturbance.

TLDR
Depletion ofspecies from deep-sea environments that dominate mid to upper trophic levels may have long-term ecological implications, but the risks of reduced stock size and agestructure to population viability, the potential for species replacement, and the impacts on prey and predator populations are not generally known.

TLDR
The occupation of this area by species exploiting abundant food supplies may lead to strong vertical gradients in selective pressures for optimal rates of growth, modes of reproduction and development and in other aspects of species biology. Expand
