Antarctic sea ice plays a crucial role in the global climate system and is highly sensitive to climate change and variability (Walsh 1983; Liu et al. 2002; Roach et al. 2020). Sea ice seasonally covers a vast area of the high-latitude Southern Ocean each year…
Antarctic sea ice plays a pivotal role in the global climate system. Forming a highly reflective, dynamic, and insulative blanket that varies seasonally in its areal coverage from ~3 × 106 km2 to ~19–20 × 106 km2, sea ice and its snow cover strongly modifies ocean…
Antarctic sea ice plays a pivotal role in the global climate system. Forming a highly-dynamic reflective and insulative blanket that varies seasonally from ~3 to ~20 × 106 km2, sea ice and its snow cover strongly modify ocean–atmosphere fluxes and interaction processes (Bourassa et al. 2013).
The Southern Ocean is vitally important in understanding climate change, both regionally and globally, due to factors such as the presence of the Antarctic Circumpolar Current, seasonal sea-ice and strong Southern Hemisphere westerly winds. Also, the upper branch of the Circumpolar Deep Water (UCDW)…
For many species trophic interactions are difficult to study because of their cryptic habits and/or the unfavourable characteristics of samples for traditional diet techniques. DNA-based diet techniques are sensitive…
The upwelling of iron-rich Upper Circumpolar Deep Water (UCDW) is thought to be critical for primary production in the Southern Ocean, since iron has been shown to be a limiting factor in what is otherwise a high nutrient region.
Mitochondrial ribosomal DNA is commonly used in DNA-based dietary … analyses. In such studies, these sequences are generally assumed to be the … only version present in DNA of the organism of interest. However…
The oxygen isotopic record obtained from Globigerina bulloides, Globorotalia inflata, and Neogloboquadrina pachyderma … (s.) was analysed for 5 sediment traps moored in the Southern Ocean and Southwest Pacific. The traps extend from Subtropical … to the Polar Frontal environments…
