Authors Summary
SC/69a/EMXX provided a high-level summary of a new Australian Antarctic Science project titled Managing Antarctic Krill and Conserving the Krill-based Ecosystems (KaKE). This 10-year project has two main goals: 1) To inform the sustainable and ecosystem-based management of the East Antarctic krill fishery; and 2) To quantify the current and projected impacts of climate change on East Antarctica's krill-based ecosystem. A large body of cetacean-focused research has been proposed under this project which aims to assess the spatial and temporal distribution and variability of krill consumption by whales in areas likely to be targeted by an East Antarctic krill fishery. The current project team seeks to develop collaborations with other nations and scientists that conduct research into the Southern Ocean’s krill and krill-based ecosystem.

Abstract
Antarctic krill are a fundamental component of Southern Ocean ecosystems and perturbations to krill populations have ramifications for the entire ecosystem. Krill are fished across the Southern Ocean and sustainable management of this fishery is a high priority for the Australian Government. A new Australian Antarctic Science project - Managing Antarctic Krill and Conserving the Krill-based Ecosystems (KaKE) – has been developed to design, develop and implement an integrated and comprehensive interdisciplinary program of scientific research and monitoring in East Antarctica that will provide new and important insights into krill biology and the Southern Ocean’s krill-based ecosystem. This decade-long project will include annual interdisciplinary field surveys on RSV Nuyina, Australia’s new icebreaker, as well as annual deployments of moored platforms to support autonomous echosounders and passive acoustics. The project will develop new capabilities for krill predator research including: new molecular methods to detect predators and determine their diet; the use of long and short-range uncrewed aerial vehicles for predator surveys, collection of whale biopsies and whale tagging; and the deployment of newly developed systems for the autonomous visual and infrared detection of whales. These activities will culminate in outputs to inform the ecosystem-based sustainable management of the East Antarctic krill fishery and quantify the current and projected impacts of climate change. The project welcomes expressions of interest from potential collaborators.
