Stable isotope analysis reveals trophic variation in adult Antarctic krill (Euphausia superba) around the Antarctic Peninsula from austral fall to early winter
Abstract: 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

VME detection thresholds: preliminary results of a study on the case of the sea pens (Pennatulacea) of the CCAMLR sector 58.4.4b
Abstract: CCAMLR has defined Vulnerable Marine Ecosystems (VME) detection thresholds based on the benthos bycatch monitoring. When these thresholds are reached during a single longline fishing operation, the data are reported to the Secretariat to inform the CCAMLR about the potential presence of

Adult male Antarctic fur seals: tourists, trouble makers or marine ecosystem sentinels?
Abstract: Resource competition often results in mechanisms that ameliorate its effects, typically through the partitioning of resource exploitation either temporally or spatially. Understanding the spatial and temporal overlap between predators that exploit the same resource then is fundamental

Population variability of biological parameters of penguins along the Antarctic Peninsula
Abstract: 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

Krill physiology and impact of temperature variations: a comparative approach
Abstract: 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

Unfolding connectivity patterns along the Antarctic Circumpolar Current in the sub-Antarctic region
Abstract: 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

Extinction risk of Antarctic and sub-Antarctic colonies of Pygoscelid penguins under climate change context
Abstract: 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

Important marine mammal areas (IMMAs) – scientific protocol
Abstract: The Marine Mammal Protected Areas Task Force (MMPA Task Force) was established in 2013 by the International Committee on Marine Mammal Protected Areas (ICoMMPA), the International Union for Conservation of Nature (IUCN), the Vice-Chair of the World Commission on Protected Areas (WCPA),

Supervised and unsupervised (RapidKrill) estimates of krill density from DY098
Abstract: We compare supervised, using the interactive software Echoview™, and unsupervised, using python, processing of acoustic data collected during the UK cruise DY098. The same data processing procedures are applied in both methods, and we show that the unsupervised method comes

Preliminary biomass estimation of Antarctic krill based on the swarm-based method for CCAMLR Division 58.4.1 in 2018/19 using data obtained by Japanese survey vessel Kaiyo-maru
Abstract: Biomass (B 0) of Antarctic krill for CCAMLR Division 58.4.1 in 2018/19 was preliminarily estimated as 4.349 million ton (CV=54.8 %) based on the swam based method using data obtained by Kaiyo-maru. The point estimate was comparable with the estimate in 1996 by BROKE (4.83 million ton
