    Microbial processes of carbon cycle as the base of food chain of Håkon Mosby Mud Volcano benthic community (1999)
    Springer
    Geo-marine letters 19 (1999), S. 89-96 
    Details
    ISSN: 1432-1157
    Source: Springer Online Journal Archives 1860-2000
    Topics: Geosciences
    Notes: Abstract  Box and gravity cores recovered from the Håkon Mosby mud volcano (HMMV) during cruise 15 of the R/V Professor Logachev were analyzed for bacterial activity and benthic fauna distribution. The high bacterium number (up to 9.6×109 cells cm-3 of the sediment) and marked rates of sulfate reduction (up to 0.155 mg S dm-3 day-1) and methane oxidation (up to 9.9 μg C dm-3 day-1) were shown for the upper horizons of the sediments of the HMMV peripheral zone. The benthic community is characterized by the presence of two pogonophoran species, Oligobrachia sp. and Sclerolinum sp., harboring symbiotic methanotrophic bacteria.

    Towards improved understanding of the diversity and abundance patterns of the mid-ocean ridge macro- and megafauna (2008)

    Description: Mid-ocean ridges are vast features of all oceans but their fauna and ecological significance remain poorly understood. Ridge studies in recent decades were understandably biased in favour of the newly discovered chemosynthetic ecosystems. Investigations of photosynthesis-based systems and communities associated with ridges were scattered and few despite their much larger scale and significance for ocean productivity patterns and biogeography and for the management of human activities on the high seas. This knowledge gap was recognised by the Census of Marine Life (CoML) programme and led to the initiation of a dedicated field project on non-chemosynthetic systems and communities of a mid-ocean ridge. The present collection of articles highlights results from the project ‘Patterns and Processes of the Ecosystems of the northern Mid-Atlantic’ (MAR-ECO), the CoML field project that aims to explore the diversity and distribution patterns of photosynthesis-based communities of mid-ocean ridges by a range of classical and new technologies and methods. In 2003–2005, comprehensive investigations were conducted on pelagic and epibenthic macro- and megafauna of the Mid-Atlantic Ridge between Iceland and the Azores. Several research vessels participated in the first field phase of the project, but the majority of the results were from a 2-month international expedition on the Norwegian vessels R.V. G.O. Sars and the chartered fishing vessel M.S. Loran in 2004. This introduction explains the background and goals of MAR-ECO, summarizes the strategies and sampling efforts, and briefly introduces future plans as the project enters a second field phase in 2007–2009.

    A strategy for the conservation of biodiversity on mid-ocean ridges from deep-sea mining (2018)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2018-07-05
    Description: Mineral exploitation has spread from land to shallow coastal waters and is now planned for the offshore, deep seabed. Large seafloor areas are being approved for exploration for seafloor mineral deposits, creating an urgent need for regional environmental management plans. Networks of areas where mining and mining impacts are prohibited are key elements of these plans. We adapt marine reserve design principles to the distinctive biophysical environment of mid-ocean ridges, offer a framework for design and evaluation of these networks to support conservation of benthic ecosystems on mid-ocean ridges, and introduce projected climate-induced changes in the deep sea to the evaluation of reserve design. We enumerate a suite of metrics to measure network performance against conservation targets and network design criteria promulgated by the Convention on Biological Diversity. We apply these metrics to network scenarios on the northern and equatorial Mid-Atlantic Ridge, where contractors are exploring for seafloor massive sulfide (SMS) deposits. A latitudinally distributed network of areas performs well at (i) capturing ecologically important areas and 30 to 50% of the spreading ridge areas, (ii) replicating representative areas, (iii) maintaining along-ridge population connectivity, and (iv) protecting areas potentially less affected by climate-related changes. Critically, the network design is adaptive, allowing for refinement based on new knowledge and the location of mining sites, provided that design principles and conservation targets are maintained. This framework can be applied along the global mid-ocean ridge system as a precautionary measure to protect biodiversity and ecosystem function from impacts of SMS mining.

    A re-description of the enigmatic deep-sea holothurian Irpa abyssicola (Elpidiidae, Elasipodida) with remotely operated vehicle observations on benthic organisms in the Norwegian-Greenland Basin (2003)

    Publication Date: 2014-09-17
    Description: The deep-sea holothurian Irpa abyssicola (Elpidiidae) has been re-discovered in the Norwegian-Greenland Basin after more than 100 years. The remotely operated vehicle Victor 6000 was used to collect specimens and to make observations on the biology (density, distribution and behaviour) of the benthic megafauna during a dive to the Hayes Deep (maximum depth ca. 3700 m). The specimens of Irpa abyssicola were in exceptionally good condition, allowing a re-description of the species. The original description of the holothurian was found to lack many significant morphological details. In particular, it is clear from the new specimens that three pair of dorsal papillae fuse to form a velum in an anterior third of the body. There are no separate dorsal papillae, as described originally.

    Horizontal distribution patterns in arctic macrobenthic communities (Poster) (2006)
    In:  EPIC311th Deep-Sea Biology Symposium, Southampton, U.K..-14.07.2006., 09
    Details
    Publication Date: 2014-10-07
    Description: Horizontal distribution patterns of macrobenthos were studied based on material collected at the deep-sea long-term observatory HAUSGARTEN off West Spitsbergen (79°N) during the RV Polarstern expedition ARK XIX/3c in July-August 2003. Macofauna was obtained at water depths between 2500 and 2600 m. Samples were arranged using a hierarchical approach to analyze benthic fauna distribution at different scales. Three stations were performed along the 26 km transect. Three giant box-corers (0.25 m²) were taken at each station. Five subcores (12.5ґ12.5 cm) were extracted from each box corer. Total macrofauna biomasses varied from 2.31 g ww m2 to 6.41 g ww m2, and densities ranged from 1976 ind. m2 to 3254 ind. m2. Both qualitative and quantitative methods of statistical analysis confirmed that all samples belong to one benthic community with the dominant species complex Tetractinomorpha gen.sp. K_Diastylis K_polaris K_Myriochele K_heeri K_Galathowenia K_fragilis. The inner heterogeneity in species relative abundance and composition was found at a sub-community level. Multivariate analysis showed the division of all samples into two clear groups on the subcore and corer levels. The set of species at the lowest examined level (i.e. in a subcore) allowed the identification of two types of benthic sub-communities. The size of these sub-communities appeared to be not less than several km across. The hierarchical organization of benthic communities on the continental slope off Spitsbergen includes at least two levels: communities, which replace each other along the depth gradient (Wlodarska-Kowalczuk et al. 2004), and sub-communities which make up the orthogonal inner mosaics in each vertical zone.
