Ecologically or Biologically Significant Areas (EBSAs)

  published: 12 Jun 2015

North-eastern Barents–Kara Sea

General Information
The area is an example of a unique, pristine and vulnerable High Arctic marine cryopelagic ecosystem characteristic of the Atlantic region. Its bathymetry consists of an archipelagic shelf and adjacent shelf break with numerous deep-water canyons; a marginal ice zone moves through the area in the course of theyear. Its surface waters are typical Arctic waters, with Atlantic waters flowing along the continental slope and enriching local communities and biological productivity. The area has a high abundance of typical Arctic species (e.g., seabirds, marine mammals, benthic invertebrates), with core areas for several globally threatened species of birds and marine mammals.
The report titled Identification of Arctic Marine Areas of Heightened Ecological and Cultural Significance: Arctic Marine Shipping Assessment (AMSA IIc) (identified the marine areas around Franz- Josef Land archipelago, as well as the polynyas west and east of the Severnaya Zemlya archipelago, as areas of heightened ecological significance that meet the IMO ecological criteria for PSSAs (AMAP/CAFF/SDWG, 2013). The IUCN/NRDC Workshop to Identify Areas of Ecological and Biological Significance or Vulnerability in the Arctic Marine Environment (Speer and Laughlin, 2011) identified an area named “High Arctic Islands and Shelf” as meeting nearly all CBD criteria. The workshop report noted that, “This area includes a mix of large and small islands that together are the northern-most archipelago in the Russian and Norwegian Arctic. The region harbors abundant and diverse coastal benthic communities, and supports colonies of high Arctic seabirds, ice-associated marine mammals and polar bears. Atlantic water masses along the continental shelf break in the northern part of the area are associated with summer ice edge habitat supporting abundant and diverse zooplankton and polar cod (Boreogadus saida). It is a key area for the endangered Spitsbergen stock of bowhead whale, the northern stock of the East-Atlantic meta-population of Atlantic walrus (Odobaenus rosmarus rosmarus), and most of the world’s breeding population of the threatened ivory gull (the region provides post-breeding staging grounds for ivory gulls from all North-East Atlantic populations)” (Speers and Laughlin, 2011). As the above-mentioned EBSA is a large, non-uniform area that includes different sub-areas that meet the EBSA criteria in different ways, here we give descriptions and updated information for the part of the area located off Russian islands, including areas corresponding to several “elementary” EBSAs mapped and listed in annexes 1 and 2 to the IUCN/NRDC workshop report.
Description of the location
Arctic
The area covers the High Arctic Russian archipelagos of Franz-Josef Land and Severnaya Zemlya, and several offshore islands, internal archipelagic waters and inland seas, the adjacent Russian territorial waters and the EEZ.

Area Details
The seabed topography is complex and includes archipelagic shelf and adjacent shelf break. This High Arctic ecosystem is enhanced by Atlantic water masses flowing along the continental shelf break. The area is characterised by higher abundances of zooplankton as compared to adjacent waters (Kosobokova 2012, figure 2). The prominent feature is marginal ice zone associated with this area, including recurrent flaw polynyas (off Franz Josef Land, west and east off Severnaya Zemlya) and the edge of drifting ice which has a seasonal distribution, shifting from south of the area in winter to the north, where it coincides in summer with the shelf break (figure 3), i.e. providing physical drivers for enhanced biological productivity (Eimer et al., 2013). In other words, the area is a dynamic marginal ice zone on an annual basis (see climatic ice extent charts in National Ice Center 2006, updated 2009). The marginal ice zone and offshore polynyas developing around the archipelagos (Popov and Gavrilo, 2011) are generally associated with enhanced primary production. The regional maxima of primary production around the archipelagos of Franz Josef Land and Severnaya Zemlya are particularly important in spring (April – May) when surrounding areas are under ice and show low productivity (Vetrov and Romankevich, 2011). Enhanced regional productivity and advection of zooplankton with the Atlantic water (Kosobokova, 2012) supports higher trophic levels, including polar cod and top predators, seabirds and marine mammals. The area is abundant in seabird colonies typical of the High Arctic (dominated by Dovkies/Little auks, Thick-billed murres/Brunnich’s guillemots, and Kittiwakes), ice-associated marine mammals and polar bears. It is the principal area for endangered Spitsbergen stock of owhead whale (IUCN EN) (Reeves et al., 2014) with the highest known densities (Gavrilo, unpublished data), northern stock of the East-Atlantic meta-population of Atlantic walrus Odobaenus rosmarus rosmarus, most of the world’s breeding population of the threatened ivory gull (IUCN NT) (Gavrilo, 2011), post-breeding staging grounds for ivory gulls from all of the North-East Atlantic populations (Gilg et al. 2010, figure 4). The coastal marine ecosystem of Franz-Josef Land is very rich and diverse, with benthic communities showing signs of pristine marine ecosystems (recent studies, 2013, National Geographic Pristine Seas – Franz-Josef Land expedition – 2013, under preparation).
This is dynamic area with evidence of current changes under conditions of global climate change. The most prominent changing features are the conditions and distribution of ice, with the summer ice edge shifting north for a great extent over the past decade. This has affected distribution patterns and foraging conditions of many ice-associated species, primarily polar bears, ice-associated seals, and ivory gulls. The recent changes may favour some species, such as bowhead whales and Atlantic walrus, but further investigations are required. This area is partly covered by federal specially protected areas (National Park Russian Arctic, Franz-Josef Land federal reserve (zakaznik), Severozemelsky federal reserve), so monitoring and basic research are ongoing and planned for the future. Some spots around abandoned polar stations and military bases have high concentrations of remnants of the previous epoch of Arctic exploration and exploitation industrial waste. Of particular danger for the environment are barrels with remaining fuel, which are gradually being cleaned up. Actual (on Franz Josef Land) and potential areas of tourism development are considered hotspots for disturbance. The major developing threat to the area is the booming shelf petroleum exploration and coming exploitation. Recently issued petroleum licences partly overlap with the area described and even overlap with some already existing federally protected areas (Franz-Josef Land federal refuge, Great Arctic reserve, Severozemelsky federal refuge).
