1. The winter pack-ice zone provides a sheltered but food-poor habitat for larval Antarctic krill

   Abstract:  A dominant Antarctic ecological paradigm suggests that winter sea ice is generally the main feeding ground for krill larvae. Observations from our winter cruise to the southwest Atlantic sector of the Southern Ocean contradict this view and present the first evidence that the pack-ice

2. Competition-induced starvation drives large-scale population cycles in Antarctic krill

   Abstract:  Antarctic krill (Euphausia superba)—one of the most abundant animal species on Earth—exhibits a five to six year population cycle, with oscillations in biomass exceeding one order of magnitude. Previous studies have postulated that the krill cycle is induced by periodic climatological

3. Proposed continuation of a multi-Member longline survey on Antarctic toothfish (Dissostichus mawsoni) in Statistical Subarea 48.6 in 2018/19 by Japan and South Africa

   Abstract:  Japan and South Africa propose to continue investigating the population structure and various demographic parameters of Antarctic toothfish (Dissostichus mawsoni) in the Subarea 48.6 in 2018/19 using standardized longline gear, established tagging techniques, and pop-up tags. The

5. Plan of research program of the Ukraine in Subarea 88.3 in 2019

   Abstract:  The research of Dissostichus in Subarea 88.3 carried out by Chile in 1998, New Zealand in 2005, Russia in 2011 and 2012 and the Republic of Korea in 2017 and 2018. It was noted that no tagged fishes were recaptured during the previous research activities. Studies are planned to be

7. Spatial and temporal distribution patterns of acoustic backscatter in the New Zealand sector of the Southern Ocean

   Abstract:  Mid-trophic level organisms (MTLO) of open-ocean marine ecosystems play a key role linking primary and tertiary consumers. Despite their importance, characterisation of MTLO is limited due to sampling difficulty, and is largely obtained through active acoustics. Acoustic data collected

8. Predicting distribution and relative abundance of mid-trophic level organisms using oceanographic parameters and acoustic backscatter

   Abstract:  Data on the distribution and abundance of mid-trophic level organisms (MTLOs) in the pelagic open-ocean ecosystem are normally sparse or absent. Consequently, ecosystem models are limited in their ability to support decision-making for issues ranging from fisheries management to

9. Casal2: New Zealand’s integrated population modelling tool

   Abstract:  Casal2 (pronounced Casal-two) has replaced CASAL, New Zealand’s integrated fish stock assessment pack-age since 2002. Casal2 replicates most of CASAL’s functions such as many stocks, fisheries, and areas; age-or length-based dynamics; the use of several data sources (e.g., abundance

10. Diet overlap among top predators at the South Orkney Islands, Antarctica

    Abstract:  In order to understand interspecific trophic relationships among top predators, we analyzed diet information on nine bird and two seal species collected in the austral summer from 1996 to 2000 at South Orkney Islands. Overall, the diet of most of the predators was mainly composed of
