1. Krill faecal pellets drive hidden pulses of particulate organic carbon in the marginal ice zone

   Abstract:  The biological carbon pump drives a flux of particulate organic carbon (POC) through the ocean and affects atmospheric levels of carbon dioxide. Short term, episodic flux events are hard to capture with current observational techniques and may thus be underrepresented in POC flux

2. Krill (Euphausia superba) distribution contracts southward during rapid regional warming

   Abstract:  High-latitude ecosystems are among the fastest warming on the planet. Polar species may be sensitive to warming and ice loss, but data are scarce and evidence is conflicting. Here, we show that, within their main population centre in the southwest Atlantic sector, the distribution of

3. The importance of sea ice association of Antarctic krill for transport and retention in the South Orkneys region: a modelling study

   Abstract:  The South Orkney Islands region is a key location for understanding the distribution of Antarctic krill in CCAMLR Area 48. The local krill populations support krill-dependent higher predators and krill fisheries, and the regional oceanographic circulation provides connections between the

4. Considerations about managing the krill fishery at small spatial and temporal scales

   Abstract:  We discuss a number of ecological issues in relation to CCAMLR’s aspiration for managing the krill fishery at small temporal and spatial scales. We highlight that the devil is in the detail, and a lot of detail is potentially necessary for managing at these smaller scales. Much of this

5. Developing layers for a Risk Assessment for Subarea 48.1 using data from at-sea sightings

   Abstract:  CCAMLR has endorsed the use of the Risk Assessment framework to apportion the krill catch limits in order to minimise the risk of the fishery to krill dependent predators. We plan to apply the risk assessment framework across Subarea 48.1 at various spatial and temporal scales, in order

6. Developing a Risk Assessment for Subarea 48.1 using tracking data

   Abstract:  CCAMLR has endorsed the use of the Risk Assessment framework to apportion the krill catch limits in order to minimise the risk of the fishery to krill dependent predators. We plan to apply the risk assessment framework across Subarea 48.1 at various spatial and temporal scales, in order

7. The Mapping Application for Penguin Populations and Projected Dynamics (MAPPPD) database: a tool for helping stakeholders monitor penguin population trends in Antarctica

   Abstract:  The Mapping Application for Penguin Populations and Projected Dynamics (MAPPPD) is a web-based, open access, decision support tool designed to assist scientists, non-governmental organizations, and policymakers working to meet the management objectives as set forth by The Commission for

8. Proposal for a krill biomass survey for krill monitoring and management in CCAMLR Division 58.4.2-East

   Abstract:  Australia plans to conduct a krill biomass survey in Division 58.4.2 East during 23 January to 25 March 2021. The survey will estimate krill biomass with a view to update the precautionary catch limit for krill. A krill observatory mooring system will also be deployed during the survey

9. Advances are urgently needed in providing regular estimates of krill stock status based on the available data

   Abstract:  CCAMLR currently manages the krill fishery in subareas 48.1 to 48.4 using an arbitrary measure (the trigger level) which was established in 1991 and is “not related to the status of the krill stock”. At the same time, CCAMLR recognises that “advances are urgently needed” specifically

10. Evidence of change to the environment, ecosystem and fishery within Area 48 indicates the need for continued precaution

    Abstract:  CCAMLR manages the krill fishery in Area 48 using a catch limit (the trigger level) which was established in 1991 based on the maximum catches reported for each subarea. Since that time the ecosystem has undergone rapid environmental change. Several studies suggest that krill numerical
