On possible influence of continuous krill fishing technology with the use of ‘air-bubbling suspension system’ on ecosystem elements
Abstract: It was shown that potential increase in krill fishery in the immediate future, accompanied by introduction of highly intensive fishing and processing technologies call for studying the fishery influence on ecosystem components beyond the framework of traditional investigations of

An illustrative management procedure for exploring dynamic feedback in krill catch limit allocations among small-scale management units
Abstract: A Management Procedure (MP) approach is proposed to assist in advising regarding the subdivision of the precautionary catch limit for krill among 15 small-scale management units (SSMUs) in the Scotia Sea to reduce the potential impact of fishing on land-breeding predators. The Spatial

Managing ecosystem uncertainty: critical habitat and dietary overlap of top-predators in the Ross Sea
Abstract: We summarize three types of data in order to increase appreciation among fishery managers of the close spatial and temporal ecological overlaps among top predators in the Ross Sea Shelf Ecosystem (RSShE). This includes data on diet, foraging behavior, and habitat use. Murphy (1995)

Preliminary report from New Zealand research voyages to the Balleny Islands in the Ross Sea region, Antarctica, January to March 2006
Abstract: This paper explains the background and scientific rationale behind New Zealand’s decision to send two separate research voyages to the Balleny Islands, located north of the Ross Sea, in the Antarctic summer of early 2006. The first of these voyages involved a dedicated research

A review and update of krill biomass trends in the South Shetland Islands, Antarctica, using the simplified stochastic wave born approximation
Abstract: Using data collected from US AMLR surveys conducted in the South Shetland Islands we review the trends in biomass, size frequency distribution and proportional recruitment of Antarctic Krill (Euphausia superba) between 1997 and present. Over the last five years proportional recruitment

A nonparametric algorithm to model movement between polygon subdomains in a spatially explicit ecosystem model
Abstract: Many modern spatially explicit ecosystem models use modelling subdomains of different shape and size (‘polygons’) to resolve space, and movement of biomass between them forms an important part of the modelling effort. In marine applications, a flow field grid describing the water

Regionalisation of the Southern Ocean: a statistical framework
Abstract: Large ecosystems are often partitioned into spatial compartments (bio- or biophysical regions and/or ecoregions) in order to better understand the relative importance of ecosystem processes or for the purposes of managing human activities in relatively ecologically discrete areas.

A life table for female Antarctic fur seals breeding at Cape Shirreff, Livingston Island
Abstract: Mark-resight data were analysed for five cohorts (1997-2001) to estimate age-specific juvenile survival, age at first reproduction, and resight probabilities. Longitudinal histories of presence and pregnancy of adult females (aged by cementum annuli) were used to estimate age-specific
