Abstract
From January to March 2016, the Antarctic Climate
and Ecosystems Corporate Research Centre (ACE
CRC) led an integrated ecosystem survey voyage on
the Southern Kerguelen Axis (the region spanning
BANZARE Bank and the Princess Elizabeth Trough
(PET), south toward the Antarctic continental shelf
and Prydz Bay). The voyage track spanned 8 850 km,
comprised of eight sampling transects, which were
designed to encompass major environmental transitions
in the area (Figure 1). Overarching goals of this
voyage were to characterise pelagic food-web structure
and major energy pathways in the region, and to pilot
methodologies for future ecosystem observation and
monitoring. A key component of the study was sampling
the mesopelagic community to resolve key drivers of
the abundance and biomass of major mesopelagic taxa
(fishes, crustaceans, squids and gelatinous zooplankton),
which are key prey for higher-trophic levels, and represent
an important alternative energy pathway to krill.
