The purpose of this "paper" is to present a research project in progress on the physiology of Antarctic krill, with a focus on the response to environmental temperature variations. This study first focused on the study of heat shock proteins (HSP) and the comparative aspect quickly became essential for a better understanding of the mechanisms involved in relation to the environment. On the Read More

The sub-Antarctic region -here considered between the sub-Antarctic Front and the southern boundary of the Antarctic Circumpolar Current (ACC) -falls under many distinct jurisdictions, including Exclusive Economic Zones (EEZs) of several countries, as well as the areas of competence of several international bodies as the SEAFO, SIOFA and CCAMLR. However, in oceanographic terms, these zones Read More

A collection of published papers about population variability of several biological parameters and factors affecting penguins biology along the Antarctic Peninsula is presented in order to contribute to the general knowledge of penguin biological variation, to generate a data baseline in the context of environmental changes such as climate change and human activity and to support the proposal Read More

Ptilocrinus amezianeae is a Vulnerable Marine Ecosystem (VME) indicator species and often collected in numbers locally. P. amezianeae has been described to be restricted to oligotrophic habitats and, as a member of the family Hyocrinidae, a rare organism. Here we model P. amezianeae suitable habitat using BRT (Boosted Regression Trees) and an iterative approach to identify Read More

Several studies have emphasized the variable abundance of Pygoscelid penguins from different colonies around Antarctica. In this study, the extinction risk of Adélie, Chinstrap and Gentoo penguins was evaluated in order to identify the most endangered colonies under present-day and future environmental scenarios. The extinction risk was estimated for twelve colonies from environmentally Read More

This paper presents two new observer manuals for finfish and krill fisheries. The manuals include updated information on identifying and sexing target catch species, provide guidance on standard tasks and requirements for observers as well as supplementary information to aid data collection requirements. In addition a new version of the observer longline logbook is presented, with additions to Read More

Krill length data collected from fishery-dependent and fishery-independent data sources were analysed for trends in population structure. Krill length data collected by the Scheme of Scientific Observation (SISO) and the CCAMLR Ecosystem Monitoring Program (CEMP) from 2008 to 2019 in the Bransfield Strait were compared. Differences in mean lengths and length-frequencies were apparent, however Read More

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 during the CCAMLR 2000 acoustic survey of Antarctic krill. Conductivity-Temperature-Depth (CTD) stations Read More

India is getting prepared to take up studies on Krill associated ecosystem studies in the Western Indian Ocean sector of the Southern Ocean, through in-situ ship survey in the area during Austral summer 2019-20. The proposed objectives are to to understand the distribution and biomass of krill in the western Indian Ocean Sector of the Southern Ocean, to relate larval/adult krill with the Read More

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 estimates. We model the potential hidden flux of POC originating from Antarctic krill, whose swarming behaviour Read More

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 Euphausia superba (hereafter, ‘krill’) has contracted southward over the past 90 years. Near their Read More

The Antarctic krill (Euphausia superba) is a key species in the Southern Ocean ecosystem and an important link in the food web of the Antarctic ecosystem. The trophic information for this species during the transition from the austral fall to the winter is important to understand its poorly known overwintering mechanisms. However, the few studies on the topic differ in their results, Read More

Understanding the variation in krill diet during winter is crucial to elucidate the overwintering of krill in the Southern Ocean. The information on trophic variation of krill under ice-free waters during the winter can also provide the insight for understanding the response of krill to global warming. Stable isotope analyses (¹⁵N/¹⁴N and ¹³C/¹²C) Read More
