1. 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

2. 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

3. Habitat suitability for the VME Ptilocrinus amezianeae over the Kerguelen Plateau

   Abstract:  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

4. 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

5. 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),

8. 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

9. 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

10. Density estimation of Antarctic krill (Euphausia superba) around South Shetland Island and Elephant Island (Subarea 48.1) using two frequencies with 38 and 120 kHz

    Abstract:  The density of Antarctic krill swarm inhabiting the Subarea 48.1, which includes the Elephant Island peripheries and the west and north of the South Shetland Island, was estimated using an acoustics survey. Acoustic data were collected using two frequencies with 38 and 120 kHz from March
