Sensitivity analysis identifies high influence sites for estimates of penguin krill consumption on the Antarctic Peninsula
Read more of: Sensitivity analysis identifies high influence sites for estimates of penguin krill consumption on the Antarctic PeninsulaKrill consumption by natural predators represents a critical link between surveys and models of standing krill biomass and the design of a sustainable krill fishery for the Scotia Sea. Antarctic […]

A new 100-m Digital Elevation Model of the Antarctic Peninsula derived from ASTER Global DEM: methods and accuracy assessment
Read more of: A new 100-m Digital Elevation Model of the Antarctic Peninsula derived from ASTER Global DEM: methods and accuracy assessmentA high resolution surface topography Digital Elevation Model (DEM) is required to underpin studies of the complex glacier system on the Antarctic Peninsula. A complete DEM with better than 200m […]

A compilation of parameters for a krill-fishery predator model of the Scotia Sea and Antarctic Peninsula (working paper version)
Read more of: A compilation of parameters for a krill-fishery predator model of the Scotia Sea and Antarctic Peninsula (working paper version)We describe the compilation and derivation of parameters for use in krill-fishery-predator models of the Scotia Sea – Antarctic Peninsula region. The primary aim is to provide input for the […]

Reference observations for validating and tuning operating models for krill fishery management in Area 48
Read more of: Reference observations for validating and tuning operating models for krill fishery management in Area 48In 2007 WG-SAM defined a set of reference observations for validating and tuning proposed models to evaluate krill catch allocation options for Area 48 (the SAM calendar). The observations, which […]

Prospects for a sustainable increase in the availability of long chain omega 3s: lessons from the Antarctic krill fishery.
Read more of: Prospects for a sustainable increase in the availability of long chain omega 3s: lessons from the Antarctic krill fishery.• The global summit on nutrition, health and human behaviour (GSNHHB) identified the objective of increasing “the availability of long chain Omega‐3 (especially docosahexaenoic acid) for human consumption in a […]

A new multi-gas constrained model of trace gas non-homogeneous transport in firn: evaluation and behaviour at eleven polar sites
Read more of: A new multi-gas constrained model of trace gas non-homogeneous transport in firn: evaluation and behaviour at eleven polar sitesInsoluble trace gases are trapped in polar ice at the firn-ice transition, at approximately 50 to 100 m below the surface, depending primarily on the site temperature and snow accumulation. […]

Trampling on maritime Antarctica: can soil ecosystems be effectively protected through existing codes of conduct?
Read more of: Trampling on maritime Antarctica: can soil ecosystems be effectively protected through existing codes of conduct?Soil trampling is one of the most obvious direct negative human impacts in Antarctica. Through a range of experiments and field studies based on quantitative physical (soil penetration resistance) and […]
