A new feature introduced in this edition is a section containing four essays: The HUDSON 70 Expedition by C.R. Mann Earth Sciences Studies in Arctic Marine Waters, 1970 by B.R. Pelletier Analysis of Marine Ecosystems by K.H. Mann Operation Oil by C.S. Mason and Wm. L. Ford They serve as an overview of the focal interests of the past two years in contrast to the body of the Review, which is basically a series of individual progress reports. The search for petroleum on the continental shelves of Eastern Canada and Arctic intensified considerably with several drilling rigs and many geophysical exploration teams in the field. To provide a regional depository for the mandatory core samples required from all drilling, the first stage of a core storage and archival laboratory was completed in 1970. This new addition to the Institute is operated by the Resource Administration Division of the Department of Energy, Mines & Resources. In a related move the Geological Survey of Canada undertook to establish at the Institute a new team whose primary function will be the stratigraphic mapping of the continental shelf.

    Biodiversity and Conservation 5, 1451-1471 (1996) Biodiversity in extreme aquatic environments: lakes, ponds and streams of the Ross Sea sector, Antarctica W.F. VINCENT* D~partement de biologie et Centre d'(tudes nordiques, Universit~ Laval, Sainte Foy G IK 7P4, Canada M.R. JAMES National Institute of Water and Atmospheric Research Ltd, Christchurch, New Zealand Received 19 June 1995; accepted 16 August 1995 The Ross Sea Sector (RSS) of Antarctica lies between the lines of longitude 150°E and 150°W and contains diverse landscapes with a variety of lakes, ponds and streams. Neither insects nor crustacean species have been recorded in these ecosystems but most contain planktonic and/or benthic communities that are composed exclusively of microscopic organisms. Microbial biodiversity is low with a small number of species (e.g. filamentous cyanobacteria of the family Oscillatoriaceae) occurring under a broad range of environmental conditions throughout the region. There is no evidence to date of microbial endemism in the RSS; however, there is a need to apply molecular and cellular techniques to compare biodiversity and genetic characteristics with assemblages elsewhere in Antarctica and with comparable communities in the north polar zone. A series of hypotheses are advanced to help guide further work. These derive from the conclusion that environmental extremes plus biogeographical isolation control the biodiversity of RSS communities, and that biological interactions (competition, grazing, predation, parasitism) are weak and play a minor

  • Ross Sea As a Marine Protected Area
    1 CCAMLR WG-EMM-10/11 ROSS SEA BIOREGIONALIZATION Part I: Validation of the 2007 CCAMLR Bioregionalization Workshop Results Towards Including the Ross Sea in a Representative Network of Marine Protected Areas in the Southern Ocean David G. Ainley1, Grant Ballard2, John Weller3 1H.T. Harvey & Associates, 983 University Avenue, Los Gatos CA 95032; 2PRBO Conservation Science, 3820 Cypress Drive #11, Petaluma, California 94954; 3365 29th Street, Boulder, CO 80305 Weddell seal and pup beneath McMurdo Sound fast ice; photo J. Weller 2 EXECUTIVE SUMMARY This report provides the scientific basis, validating the results of the CCAMLR Bioregionalization Workshop (2007) as well as the report of ASOC (2010), for identifying the Ross Sea as one of 11 areas deserving close scrutiny for inclusion in a network of marine protected areas. CCAMLR (2007) identified the Ross Sea as an area of high biodiversity on the basis of its high physical heterogeneity; ASOC (2010) compared characteristics of the Ross Sea to areas designated under various international agreements instituted to preserve biodiversity. The CCAMLR (2007) subsequently was endorsed in the joint meeting of CCAMLR's Scientific Committee and the Environmental Protocol's Committee on Environmental Protection (ATCM XXXII-CEP XII, Final Report, 2009). Considered herein is the Ross Sea shelf and slope, which is a smaller portion of the area identified in CCAMLR (2007) as “Ross Sea shelf”. Waters overlying the Ross Sea continental shelf and slope comprise ~2.0% of the Southern Ocean, an area inconsequential in size from a global perspective. However, as shown by this summary of information — amassed from the national research programs especially of Italy, New Zealand, United Kindgom (during the “heroic” era), and United States — the Ross Sea not inconsequential is its biodiversity nor its disproportionate contribution to world populations of many well-known iconic Antarctic species.
