ENSO (El Niño Southern Oscillation) events are becoming more frequent and more intense as climate change continues. Although ENSO effects are known to propagate into the southwest Atlantic, knowledge of […]
As a net source of nutrients fuelling global primary production, changes in Southern Ocean productivity are expected to influence biological carbon storage across the global ocean. Following a high-emission, low-mitigation […]
In the extreme conditions of Antarctica two native vascular plants are present, Colobanthus quitensis (Kunth) Bartl. (Caryophyllaceae) and Deschampsia antarctica Desv. (Poaceae), distributed along the western Antarctic Peninsula and the […]
A good understanding of biotic interactions is necessary to accurately predict the vulnerability of ecosystems to climate change. Recently, co-occurrence networks built from environmental DNA (eDNA) metabarcoding data have arisen […]
Previously the geomagnetic Ap index has been used as a proxy to produce empirical energetic electron precipitation (EEP) forcing representations suitable for incorporation into coupled-climate model runs. The long-running Ap […]
Subglacial weathering releases biologically important nutrients into meltwaters that have the potential to influence downstream ecosystems. There is a need to understand how accelerated glacial retreat could impact biogeochemical cycling […]
The rainfall patterns in Eastern Asia are largely a consequence of the Asian winter and summer monsoons. On timescales 10 4 –10 6 of years, the position and strength of […]
The porbeagle shark Lamna nasus, a top predator in the North Atlantic, is vulnerable to anthropogenic stressors due to its life history characteristics. Understanding its biology, abundance and spatial ecology […]
Anthropogenic greenhouse gas emissions significantly impact the middle and upper atmosphere. They cause cooling and thermal shrinking and affect the atmospheric structure. Atmospheric contraction results in changes in key atmospheric […]
Recent intensification of the Southern Hemisphere Westerlies has resulted in important changes to ocean circulation, Antarctic ice shelf stability and precipitation regimes in the continents abutting the Southern Ocean. Efforts […]
Polar ecosystems are threatened by non-native plants, and this risk will increase with climate warming. Non-native plant growth depends on Antarctic environmental conditions and substrates, but these influences are poorly […]
Marine mammal foraging grounds are popular focal points for marine protected area (MPA) implementation, despite being temporally dynamic, requiring continuous monitoring to infer prey availability and abundance. Marine mammal distributions […]
