Mediterranean ecosystems, one of the most significant global hotspots of biodiversity, are threatened by invasive weeds. Although endomicrobiomes – the vast array of microbes colonising living plant tissues – are […]
The Atlantic walrus (Odobenus rosmarus rosmarus) is an Arctic endemic species that is under increasing threat due to declines in their sea ice habitats. Walruses rely directly (e.g., resting, giving […]
Authigenic precipitation of clay minerals in marine sediments, termed reverse weathering, is an important process in global biogeochemical cycles due to its role in regulating alkalinity and nutrient budgets. Dissolved […]
The geomagnetic storm of 10–11 May 2024 (G5-level) caused major ionospheric disturbances, providing an opportunity to examine its wide-ranging effects. This study analyzes ionospheric perturbations over mid- and high-latitude regions […]
The use of animal-borne devices to measure acceleration has yielded insights into animal locomotion, behaviour and energy expenditure. We present the first systematic review of accelerometry on animals, spanning 60 years, […]
Two species of Southern Ocean icefish (Channichthyidae) were recently assessed using the International Union for Conservation of Nature (IUCN) Red List criteria, with the South Georgia icefish (Pseudochaenichthys georgianus) categorised […]
Ice is anisotropic, with its viscosity varying by an order of magnitude in different directions when ice crystals align. However, how this variation affects ice flow is not well understood. […]
The global overturning circulation (GOC) is the largest scale component of the ocean circulation, associated with a global redistribution of key tracers such as heat and carbon. The GOC generates […]
Zygnematophycean “glacier algae” form extensive blooms on ablating glacier surfaces despite the ultra-oligotrophic conditions apparent. Previous work has postulated that this oligotrophic bloom paradox is due to (i) lower nutrient […]
The Northeast Greenland Ice Stream (NEGIS), the largest ice stream draining the Greenland Ice Sheet (GrIS), is losing mass at an accelerating rate due to atmospheric and ocean-driven melting. Holding […]
Katabatic winds are a key feature of the climate of Antarctica, but despite decades of extensive studies, substantial biases remain in their representation in atmospheric models. However, it is often […]
