Voyage summary

Research voyage to Antarctica to investigate the distribution, density and connectivity of populations of Antarctic krill, and better understand the distribution and contribution of deep-sea krill to overall krill biomass. The voyage .

The voyage is named TEMPO (Trends in Euphausiids off Mawson, Predators, and Oceanography) and is led by Chief Scientist Dr So Kawaguchi , Australian Antarctic Division (AAD).

The conceptual understanding of krill life history has been largely based on research within the epipelagic zone (surface to 250m). However, recent observations indicate that krill can exist down to the abyssal zone (deeper than 2000m). 

This research voyage will use lowered instruments and moorings to obtain full-depth vertical profiles of krill density. Researchers will also study krill behaviour at the scale of a) the individual, b) swarms, and c) groups of swarms, using advanced echo sounders on RV Investigator. This research will inform the Commission for the Conservation of Antarctic Marine Living Resources’ (CCAMLR) on the sustainable management of the krill fishery in waters off Australia’s Antarctic Territory near Mawson research station and Amery Ice Shelf.

The voyage also includes the following research projects:

  • Deployment of 12 Argo floats: BCG and Standard (Prof Tom Trull and Prof Steve Rintoul, CSIRO – shore-based)
  • CAPRIX: Cloud Aerosol Precipitation Radiation Interactions eXperiment (Dr Alain Protat, BOM shore-based)

The science team on this voyage includes 31 participants from six institutions, including CSIRO, Australian Antarctic Division (AAD), Australian Antarctic Program Partnership (AAPP), Institute for Marine and Antarctic Studies (IMAS) and University of Sydney. 

COVID-19 Protocols

To safeguard the health and well-being of participants, strict COVID-19 protocols will apply to all activities on this voyage, including testing of all participants for COVID-19 prior to departure.

Voyage outcomes

Summary of voyage outcomes - as well as voyage image gallery - will be published approximately three months after the completion of the voyage.
