“…Over the last 10 years, several studies have focused on the effects of exploratory offshore drilling in response to the growing interest by the oil and gas industry to move operations further offshore (Currie and Isaacs, 2005;Ellis et al, 2012;Bakke et al, 2013;Paine et al, 2014). This offshore shift is especially true for countries such as the United Kingdom, Norway, Italy, Malaysia, Indonesia, and Australia, which number among the leading oil-producing countries (Patin, 1999).…”

Ecological Role of Submarine Canyons and Need for Canyon Conservation: A Review

Submarine canyons are major geomorphic features of continental margins around the world. Several recent multidisciplinary projects focused on the study of canyons have considerably increased our understanding of their ecological role, the goods, and services they provide to human populations, and the impacts that human activities have on their overall ecological condition. Pressures from human activities include fishing, dumping of land-based mine tailings, and oil and gas extraction. Moreover, hydrodynamic processes of canyons enhance the down-canyon transport of litter. The effects of climate change may modify the intensity of currents. This potential hydrographic change is predicted to impact the structure and functioning of canyon communities as well as affect nutrient supply to the deep-ocean ecosystem. This review not only identifies the ecological status of canyons, and current and future issues for canyon conservation, but also highlights the need for a better understanding of anthropogenic impacts on canyon ecosystems and proposes other research required to inform management measures to protect canyon ecosystems.

“…They reduce dissolved oxygen and increase CO2 and toxics concentration in water [17]. The affected zone is typically within 300m radius from a well-head and the radius can extend to 2 km in sensitive cases [18,19]. The other factors challenging the organizational sustainable goals in primary energy industries include the toxicity of materials, trend in renewable energy and world-wide pandemic.…”

BJSTR. MS.ID.007405.The primary energy plays a vital role in human society and industry. With rising requirements in energy, it also draws continuous concerns in environmental issues and human health problems. One of the major concerns is greenhouse gas (GHG) emission. A company that fails to report its sustainability strategy can also fail the expectations from the community and its stakeholders. The consequence may further threaten the operation and profit of an organization. This paper reviews the primary energy industries at large and the significance of sustainability report. A reporting strategy according to GRI 101 standard is proposed in the end.

“…The importance of canyons as providers of ecosystem services was recently reviewed by Fernandez-Arcaya et al (2017). The complexity of the topography and the heterogeneity of the substrate, in addition to food input, promote a higher abundance, biomass and diversity of organisms in most canyons compared to the adjacent slope (De Leo et al, 2014Leo et al, , 2012Paine et al, 2014;Puig et al, 2015). Canyons can also provide shelter (Farrugio, 2012), and areas for recruitment (Fernandez-Arcaya et al, 2017Puig et al, 2001) and feeding (Ross et al, 2015) for some fish and crustaceans.…”

“…Canyons can also provide shelter (Farrugio, 2012), and areas for recruitment (Fernandez-Arcaya et al, 2017Puig et al, 2001) and feeding (Ross et al, 2015) for some fish and crustaceans. Unfortunately, these services are threatened by human activities, such as fishing, oil and gas exploitation, and pollution (Fernandez-Arcaya et al, 2017;Martín et al, 2014;Paine et al, 2014;Ramirez-Llodra et al, 2011;Van den Beld et al, 2016). Climate change, by increasing the number and intensity of extreme events, is also predicted to affect canyon communities (Cheung et al, 2010;Danovaro et al, 2001;Ruhl and Smith, 2004).…”

Understanding the impact of the environment on temporal trends in the composition and abundance of deep-sea species is essential for forecasting evolution of the community in the context of climate change. The recent development of deep-sea observatories enables multidisciplinary studies of long duration and high temporal resolution. We used a platform at the Ocean Networks Canada NEPTUNE Observatory located in the axis of Barkley Canyon between June 2012 and January 2015 to: (1) characterize the megabenthic community and the environmental conditions in the canyon; (2) investigate temporal patterns in the faunal community; and (3) determine the influence of environmental conditions on the observed patterns. The megafaunal epibenthic community, which included commercially important species, was composed of species known to be able to adapt to low oxygen conditions. A strong seasonal pattern characterized wind speed and direction, wave height, temperature, and chlorophyll concentration at the sea surface. The megafaunal epibenthic community exhibited seasonal patterns which were influenced by in-situ benthic boundary layer currents and temperature, weather conditions and chlorophyll concentration at the sea surface. At inter-annual scales, the surface temperature anomaly event observed in 2013 in the region could potentially impact the community structure with significant changes in species' densities, highlighting the need for longterm monitoring in the region. Highlights ► The benthic environment in the axis of Barkley Canyon (-985m) is stable on time scales > 1 d and < 3 y, and persistently hypoxic. ► The epibenthic megafaunal community is composed of species known to be adapted to low oxygen levels. ► Two major species of the community, C. tanneri and A. fimbria, are of fishery interest. ► Seasonal variations in the epibenthic megafaunal community on the axis of Barkley Canyon have been revealed. ► Inter-annual trends in abundance of major species of the community is linked with the surface temperature anomaly "the blob".
