South Georgia lies in a remote position in the circumpolar South Atlantic and forms one of the most isolated continental fragments on Earth. The basement geology of South Georgia is […]
The stability of the West Antarctic Ice Sheet (WAIS), crucial for predicting future sea-level rise, is threatened by ocean-forced melting in the Pacific sector of the Southern Ocean. While some […]
Background: Albatrosses can commute long distances to feed during the breeding season by avoiding energetically costly flapping flight. Energy from both wind and waves can be used to sustain soaring […]
Marine biological (‘blue’) carbon pathways are crucial components of the global carbon budget due to the ecosystem services they provide through the fixation of CO2 from the atmosphere. CO2 is […]
Ecological networks tend to contain many weak and only a few strong links. Furthermore, link strengths are often patterned within a network in ways that enhance system stability considerably, increasing […]
The Atlantic Meridional Overturning Circulation (AMOC) plays a critical role in regulating global heat and hydrological redistributions. A primary concern regarding AMOC is its potential future collapse, as suggested by […]
As shown by paleoclimate data and climate models, many climate systems on Earth undergo abrupt shifts when they cross tipping points (TPs), and these abrupt shifts are sometimes preceded by […]
Humans emitted millions of tons of the toxic element lead (Pb) into the atmosphere. The North Atlantic Ocean has been strongly affected by atmospheric Pb deposition, however the role of […]
During the late Paleozoic glacial ice extended from Antarctica across most of the Australian part of Gondwana. Maximum ice thickness over Antarctica was ∼5400–8000 m and over central Australia 2700–4000 […]
Methane seepage at the seafloor can form gas hydrate and sustain chemosynthetic communities of deep-sea animals. Most known hydrate seeps occur shallower than 2000 m on continental slopes, whereas hydrothermal […]
Peracarida is a large group containing twelve orders of brooding crustaceans, including the large orders Amphipoda, Isopoda, Tanaidacea and Cumacea, and a series of smaller orders, some restricted to isolated […]
The rapid expansion of glacial lakes in high-mountain regions, both in number and area, increases the risk of Glacial Lake Outburst Floods (GLOFs) to downstream communities. Optical remote sensing is […]
