The ideal approach to bioregionalisation of Antarctic and Southern Ocean shelf communities incorporates a range of data on physical, environmental and biological properties, as well as the interaction of these properties. Here, benthic invertebrate megafaunal communities of shelf habitats within the Atlantic sector of the Southern Ocean were analysed quantitatively from scientific survey trawl Read More

Bioregionalisation is a process to classify data on a range of environmental, biological and ecological attributes, resulting in a spatial framework that can be used as a planning tool for conservation and sustainable resource use. The success of this process will be dependent on establishing clear principles and objectives, focused at relevant spatial scales. Bioregionalisation analysis must Read More

Phytoplankton production during the austral summer in the Southern Ocean is known to be limited by iron and light. Distributions of satellite-detected chlorophyll-a (Chl-a) show very complex and time-variable patterns that are hard to explain. We analysed covariance between satellite-detected and modelled variables and show that this covariance in time between the mixed layer depth (MLD), sea Read More

New Zealand has a considerable body of experience creating spatial classifications of the marine environment, and applying them for management. We assert that recent innovations in multivariate statistical modeling have made possible the combined use of spatially comprehensive environmental data and discontinuous biological data to generate rigorous, objective, data-driven classifications of Read More

Innovative multivariate statistical modeling techniques allow modelers to generate spatially comprehensive species distribution layers from discontinuous biological data, by fitting complex and scale-dependent relationship between species abundance and available environmental data. These species-specific layers can then be used in bioregionalisation, for instance by classifying directly on Read More

Publicly available bathymetry and geophysical data can be used to map geomorphic features of the Antarctic continental margin and adjoining ocean basins at scales of 1:1-5 million. The geomorphic features identified and their properties can be related to major habitat characteristics such as sea floor type (hard versus soft), ice keel scouring, sediment deposition or erosion and current Read More

Factsheets outlining the physical and biological attributes of selected sectors of the CCAMLR convention area are presented. An overview of CCAMLR Area 58 (Indian Ocean Sector) illustrates bathymetry and major oceanographic features (fronts and sea ice extent) and describes the findings of the major surveys BROKE and BROKE-West. Subsidiary factsheets for the George V Land sector and Prydz Bay Read More

South Africa is currently proclaiming a Marine Protected Area (MPA) in the Exclusive Economic Zone (EEZ) of its sub-Antarctic Prince Edward Islands. The objectives of the MPA are to: 1) contribute to a national and global representative system of MPAs, 2) serve as a scientific reference point to inform future management, 3) contribute to the recovery of the Patagonian toothfish (Dissostichus Read More

Conservation of the high seas marine environment poses a significant challenge to policy-makers and managers. Marine conservation efforts are often hindered by the lack of data and the difficulties in addressing multiple, and typically conflicting uses. The majority of extant Marine Protected Areas (MPAs) are in coastal or tropical regions within national jurisdiction. Conservation of high Read More

The Continuous Plankton Recorder (CPR) Type I was first used in Antarctic waters during the 1925–1927 Discovery Expedition, and has been used successfully for 70 years to monitor plankton in the North Sea and North Atlantic Ocean. Sixty-five years later the CPR as a Type II version returned to Antarctic waters when the Australian Antarctic Division initiated a survey of the Southern Ocean on Read More

A repeat transect was run south of Tasmania, along ~140°E, during November and December 2001. NORPAC nets were deployed during a CTD transect on the southern leg, sampling four depth zones at each of 19 stations: 0–20, 20–50, 50–100 and 100–150 m. A Continuous Plankton Recorder (CPR) was deployed on the northern leg (average sampling depth = 10.5 m). Both net systems were harnessed with 270 ?m Read More

The Southern Ocean south of Australia is oceanographically complex, being characterized by double branches of the Sub-Antarctic Front (SAF), Polar Front (PF) and Southern Antarctic Circumpolar Current (SACCF), in addition to the Southern Boundary (SB) of the ACC. From 25 February to 3 March 2002 a 2150-km Continuous Plankton Recorder (CPR) transect was conducted along 140°E, between 47.02°S Read More
