We present a new general mathematical formulation of the Eikonal equations for ray tracing, which can use any internal magnetic field model. The analytical and tractable expressions are conveniently based […]
Climate change has dramatically altered the Arctic seas with significant decrease in sea ice extent and thickness and warming water temperature. The ecological impacts of such change have been described […]
The Southern Ocean is experiencing warming, melting of ice, and increasing wind. Predictions of increasing phytoplankton biomass associated with warming and declining glacial and sea ice are supported by observations. […]
Snow algae are important primary producers in Antarctic terrestrial ecosystems. As short-term Antarctic summer temperatures approach 20°C, parameterising temperature tolerance for snow algal species is key to determining how climate […]
Antarctic krill swarm structure, biomass, and distribution to the northwest of the South Orkney Islands, Southern Ocean, were investigated using a combination of acoustic and scientific net trawl data. Krill […]
The Western Antarctic Peninsula is a key area in the Southern Ocean ecosystem. Dense microalgal communities not only support diverse wildlife, but can also exert a climatic influence through CO2-uptake […]
Despite their importance in food webs and predominance among species bycaught in Southern Ocean toothfish fisheries, the trophic ecology of grenadiers of the genus Macrourus, remains poorly understood. Here, we […]
Pine Island and Thwaites glaciers dominate Antarctica’s sea-level contribution. However, it remains unclear whether their ice loss is driven by anomalously warm present-day ocean conditions, perhaps linked to anthropogenic climate […]
Strong biogeographic structure across the Southern Ocean has led to the recognition of multiple geographically restricted species in many coastal taxa. We examined evolutionary relationships within the Antarctic notothenioid fish […]
Empirical in-situ measurements of ecosystem carbon dioxide respiration (Reco) in high-latitude ecosystems remain limited, yet they are essential for understanding how tundra carbon cycling responds to climate warming across different […]
Effective fisheries management requires an understanding of the key influences on population variability. A fundamental driver of variability, particularly for isolated island populations, is the transport of planktonic early-life stages. […]
Euphausiids play important roles in ecosystems worldwide, transferring energy from primary producers to secondary consumers. Antarctic krill are the most abundant euphausiid on Earth and play important roles as critically […]
