Habitat partitioning in Antarctic krill: spawning hotspots and nursery areas
Abstract: Antarctic krill, Euphausia superba, have a circumpolar distribution but are concentrated within the south-west Atlantic sector, where they support a unique food web and a commercial fishery. Within this sector, our first goal was to produce quantitative distribution maps of all six

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

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

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

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

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

Preliminary report on the South Sandwich Island research cruise by RRS Discovery (DY098) in January-February 2019
Abstract: This paper describes the structure and preliminary results of the research cruise to investigate the marine pelagic ecosystem around the South Sandwich Islands in the austral summer of 2019. The research cruise consisted of a large scale acoustic survey, following track lines established

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
