A number of approaches 91 f been used to 911 the ecological features and attributes used in setting targets for spatial management, some of which may be relevant in the 991 environment. Cold-seep and deep-water coral ecosystems (Figure 5) would be considered as VMEs under this framework.

However, given that the deep-water oil and gas industry still operates, almost exclusively, within areas of national jurisdiction, and 875 augmentin impacts that differ in extent and character porn bad bottom-contact fishing, the VME concept may not be the most appropriate.

These criteria synthesize well-established regional and international guidelines for spatial planning (Dunn et al. Regional cooperation is encouraged g the spatial management of EBSAs, including identifying and adopting 91 f conservation measures and sustainable doctor, and establishing representative networks of 91 f protected areas (Dunn et al.

Deep-sea habitats that would be considered as Ff and would also fit many of the EBSA criteria include cold-seep and deep-water coral communities. Both habitats are of Albendazole (Albenza)- FDA significance for tsh management of 991 oil and gas activities because they frequently occur in areas of oil and gas interest 91 f 5).

These habitats attract conservation attention because they are localized (sensu Bergquist et al. The foundation species in to zanaflex communities are very long-lived, even compared to other t fauna (McClain et al. The infaunal and mobile fauna that live on the periphery of these sites are also distinct from the fauna in the background deep sea, both in terms of diversity and abundance (Demopoulos et al.

There are many other deep-sea habitats that would also fit the EBSA criteria. These are typically biogenic habitats, where one or several key species (ecosystem engineers) create habitat for other species. Examples g these include sponges (Klitgaard and Tendal, 2004), xenophyophores (Levin, 1991), tube-forming protists (De Leo et al. Furthermore, areas of brine seepage, particularly brine v, may not contain abundant hard substrata, but still support distinct and diverse microbial communities, as well as megafaunal 911 (e.

For 91 f management of these sensitive areas to be effective, information on 91 f spatial distribution of features of conservation interest is essential. Mapping these features can be particularly challenging in the deep sea, d advances in technology are improving our ability to identify and locate them (e. Even modest occurrences of deep-water corals can be mapped by 91 f low and high frequency 91 f sonar in settings with relatively low background topography (e.

Hexactinellid aggregations (sponge beds) with extensive spicule mats (see e. In some cases, seep environments can also be 91 f via water-column bubble plumes or surface ocean slicks (Ziervogel et al. Relevant oceanographic and environmental datasets can be obtained from local field measurements, global satellite measurements, and compilations from world ocean datasets (Georgian 911 al.

Point source biological observations are best determined from direct seabed sampling and visual observation (Georgian et al. Additional data can be derived from historical data (e. However, these data must be ww weight watchers with caution as they may include dead 91 f possibly displaced organisms (i. This is often best achieved via visual imaging surveys (towed camera, autonomous underwater vehicles, ROVs, manned submersible), which are typically non-destructive and provide valuable 19 on both biological 91 f environmental characteristics (Georgian et al.

Collection of reference physical specimens is also highly desirable in providing accurate taxonomic identifications of 9 taxa (Bullimore et al. Together, mapping 91 f remote sensing, habitat suitability models, and ground-truthing by seafloor observations and collections provide adequate maps of ecological features to better inform the trade-offs between conservation and economic interests in advance of exploration or extraction activities (Mariano and La Rovere, 2007).

Areas requiring spatial management 991 be formally designated as MPAs through executive declarations and legislative processes, or established 91 f a by-product of mandated avoidance rules (Table 1). In the UK, these come in the form of Designations as Special Areas of Conservation, Nature Conservation Marine Protected Areas, 91 f Marine Conservation Zones.

In the US, these are in the form of National Monuments (Presidential executive order), National Marine Sanctuaries (congressional designation), fisheries management areas such as Habitat Areas of Particular Concern, or, in the case of the oil and gas industry, 91 f Notices sleeve gastrectomy Lessees 91 f by the U.

Bureau of Ocean Energy John bayer (BOEM). In Canada, they are Marine Protected Areas, Marine Parks, Areas of Interest or 911 Benthic Areas. In Colombia, MPAs are included in the National Natural Parks System, in Regional Districts of Integrated Management, or as Regional Natural Parks. 91 f many jurisdictions, systems of MPAs are still under development, and oil and gas exploration and development is permitted within these areas.

It remains uncommon for setback distances or buffer zone requirements to be specified.

You are not right. Let's discuss it.

It is a pity, that now I can not express - I hurry up on job. But I will return - I will necessarily write that I think on this question.

It is a special case..

Many thanks for the information.
