“…We are also showing separately the distribution of CWC (Fig. 3), which are considered on a global scale among the most ecologically and economically valuable deep-water ecosystems (Roberts et al, 2009;Foley et al, 2010). Additionally, their carbonate exoskeleton permits keeping memory on former CWC presence at sites where they are either at present disappeared or waning (Delibrias and Taviani, 1985;Remia and Taviani, 2005;McCulloch et al, 2010;Malinverno et al, 2010).…”

“…In these cases, canyons can provide supporting services in the form of habitat, food, and nursery areas for commercial species (see Section Supporting services). Another provisional service of submarine canyons is as a source for cold-water corals harvested for jewelry (Foley and Armstrong, 2010). Canyons can also be a source of genetic resources.…”

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

et al. 2017

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.

“…Foley et al (2010) showed that identified ecosystem services connected to CWC are i) as 157 raw material and ornamental resources (direct use and option values), ii) habitat functions, including 158 refuge and nursery functions (indirect use values), and iii) non-use values. In the only previous SP 159 survey which has been implemented on CWC (Glenn et al, 2010), the effects of CWC-protection on 160 off-shore industrial activities was included.…”

10The world's largest concentration of cold-water coral (CWC) is found off the Norwegian coast. Most 11 CWC discoveries are recent, posing new challenges for Norwegian coastal and fisheries authorities 12 regarding the management of deep-sea resources. Scientific knowledge of CWC is limited, and many 13 citizens have not even heard about them. This creates problems for the application of stated 14 preference methods to capture their economic value, and very few such studies have been 15conducted. To fill this gap, we designed a discrete choice experiment, which was implemented in a 16 valuation workshop setting in order to derive estimates of participants' willingness to pay (WTP) for 17 increasing the protection of CWC. Despite the fact that marine industries such as oil/gas and fisheries 18 could be adversely affected by CWC protection, this did not reduce the respondents' willingness to 19 pay for further protection. The possibility that CWC play an important role as habitat for fish was the 20 single most important variable to explain respondents WTP for CWC protection. conducted. To fill this gap, we designed a discrete choice experiment, which was implemented in a 51 valuation workshop setting in order to derive estimates of participants' willingness to pay (WTP) for 52 increasing the protection of CWC. Despite the fact that marine industries such as oil/gas and fisheries 53 could be adversely affected by CWC protection, this did not reduce the respondents' willingness to 54 pay for further protection. The possibility that CWC play an important role as habitat for fish was the 55 single most important variable to explain respondents WTP for CWC protection. The survey revealed 56 a high degree of preference heterogeneity, whilst we found an average WTP for CWC protection in 57 the range of EUR 274-287. Marine organisms have long fascinated humans, as well as being of crucial importance for our well-66 being. Marine ecosystems provide supporting, provisioning, regulating and cultural ecosystem 67 services as defined in the Millennium Ecosystem Assessment (MEA, 2005). Over recent decades, 68 increasing awareness of the benefits our oceans provide has raised an interest in assessing the 69 economic value of these goods and services, although due to their "hidden" nature, many of these 70 benefits go un-noticed until they diminish (Stewart and Smout, 2013). Notwithstanding this, a 71 number of studies have recently emerged which quantify the economic benefits of protecting marine 72 species (Jobstvogt et al., 2014;Rogers, 2013;Hynes et al., 2013; Ressurreicao et al., 2011). 73 74Tropical corals have been subject to a series of economic valuation studies (see e.g. Spurgeon, 1992, 75 Pendleton, 1995, Parsons and Thur, 2007, Sarkis et al., 2012, and have been identified as the global 76 biome with the highest valued ecosystem services in aggregate (de Groot et al., 2012). Their deep-77 sea cousins, cold-water corals (CWC) have by contrast so far been subject to only one valuation 78 effort, which was l...
