| Description: | project TEMPO: Trends in Euphausiids off Mawson, Predators, and Oceanography |
| Description (full): | 1) Estimate the biomass of krill, a key parameter for updating the precautionary catch limit for the krill fishery in waters off Australia’s Antarctic Territory. 2) Understand the relationship between krill density and distribution, in particular the form, number, and spatial arrangement of swarms. 3) Relate krill distribution and density to the distribution and activity of air-breathing krill predators including seabirds and marine mammals. 4) Track the movement of krill swarms in relation to the local current field in order to evaluate inter-swarm connectivity. 5) Understand the distribution and contribution of deep-sea krill to overall krill biomass and its dynamics in the region. 6) Improve our understanding of the connectivity of krill populations, and the overlap between krill and predators, in order to design a tractable long-term monitoring plan and spatial management (small-scale management unit) of the krill fishery. 7) Oceanographic and biological (plankton) sampling to understand the habitat environment. |

Dr Kawaguchi (AAD) | The primary objective of this voyage is to ensure the orderly development of the krill fishery in waters off Australia’s Antarctic Territory. This will be achieved by updating the biomass estimate of Antarctic krill, enabling a revision of the catch limit within CCAMLR Division 58.4.2-East in the Indian Ocean (IO) sector of the Southern Ocean. Commercial krill fishing in the IO sector recommenced in 2016/17 after a 25 year hiatus. The current krill catch limit in the region is based on surveys conducted 14 years ago. There has been no regular ecosystem monitoring to assess how the system may have changed since then. |
