A line transect survey of the waters off East Antarctica (80°E-150°E; CCAMLR Division 58.4.1; IWC Areas IV &V) was conducted during January to March 1996 on the 5,000t icebreaker RV Aurora Australis. Cruise determining programs were a hydroacoustic survey to estimate Antarctic krill…
Data from the 1995/96 pelagic monitoring survey by Aurora Australis are used to provide a sightings estimate of abundance of humpback whales south of 60*S in Area IV of 900 with a CV of 0.46. This estimate is notably lower than that of 3300 for an equivalent area from the 1988/89 IWC/IDCR survey.
During the austral summer 1995/95 a cetacean sightings line transect survey was conducted on a platform of opportunity provided by Australian National Antarctic Research Expeditions krill hydroacoustic and oceanography survey of CCAMLR Division 58.4 (parts of IWC Area IV & V).
Abstract … Current ecological theory and practice, in parallel with the changing emphasis in international conservation and management organisations towards an ecosystem approach, require us to:
Bryophytes are sensitive indicators of environmental change and with climate change being expected to occur first at high latitudes, Antarctic bryophytes are ideal study systems for the detection of climate change effects.
