Antarctica and the Southern Ocean are key elements in the physical and biological Earth system. Human-induced climate change, and other human activities in the region, are leading to several potential interacting tipping points with major and irreversible consequences. Here…
Southern hemisphere humpback whale (Megaptera novaeangliae, SHHW) breeding populations follow a high-fidelity Antarctic krill (Euphausia superba) diet while feeding in distinct sectors of the Southern Ocean.
The Southern Ocean is disproportionately important in its effect on the Earth system, impacting climatic, biogeochemical, and ecological systems, which makes recent observed changes to this system cause for global concern.
Antarctic and Southern Ocean science is vital to understanding natural variability, the processes that govern global change and the role of humans in the Earth and climate system. The potential for new knowledge to be gained from future Antarctic science is substantial. Therefore…
Supporting Antarctic scientific investigation is the job of the national Antarctic programmes, the government entities charged with delivering their countries’ Antarctic research strategies. This requires sustained investment in people, innovative technologies, Antarctic infrastructures…
Cosmic rays are charged particles whose flux observed at Earth shows temporal variations related to space weather phenomena and may be an important tool to study them. The cosmic ray intensity recorded with ground-based detectors also shows temporal variations arising from atmospheric variations.
Background: Sooty (Puffinus griseus) and short-tailed (P. tenuirostris) shearwaters are abundant seabirds that range widely across global oceans. Understanding the foraging ecology of these species in the Southern Ocean is important for … monitoring and ecosystem conservation and management.
The Census for Antarctic Marine Life (CAML, IPY Project 53) will investigate the … distribution and abundance of Antarctic marine biodiversity and how it will be affected … by climate change.
Responses by marine top predators to environmental variability … have previously been almost impossible to observe directly. By … using animal-mounted instruments simultaneously recording … movements, diving behavior, and in situ oceanographic properties…
We compiled and reviewed 248 cases of reported vessel collisions with small cetaceans worldwide and with large … cetaceans in the Southern Hemisphere. Difficulties were encountered with the comparison of highly variable data in … terms of quality (evidence), sources…
