A unified framework for large-scale fabric evolution models and anisotropic rheologies
Read more of: A unified framework for large-scale fabric evolution models and anisotropic rheologiesIce 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. […]

Controls of the global overturning circulation of the ocean.
Read more of: Controls of the global overturning circulation of the ocean.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 […]

Micromelt sampling of the glacier algal nutrient environment
Read more of: Micromelt sampling of the glacier algal nutrient environmentZygnematophycean “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 […]

Ocean driven retreat of the Northeast Greenland Ice Stream following the Last Glacial Maximum
Read more of: Ocean driven retreat of the Northeast Greenland Ice Stream following the Last Glacial MaximumThe 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 […]

An extensive investigation of the ability of the ICOLMDZ model to simulate a katabatic wind event in Antarctica
Read more of: An extensive investigation of the ability of the ICOLMDZ model to simulate a katabatic wind event in AntarcticaKatabatic 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 […]

Modelling the three-dimensional, diagnostic fabric anisotropy field of an ice rise
Read more of: Modelling the three-dimensional, diagnostic fabric anisotropy field of an ice risePolar ice develops anisotropic crystal orientation fabrics under deformation, yet ice is mostly modelled as an isotropic fluid. We present three-dimensional simulations of the crystal orientation fabric of Derwael Ice […]

Early-life factors shaping the gut microbiota of Common buzzard nestlings
Read more of: Early-life factors shaping the gut microbiota of Common buzzard nestlingsBackground Exploring the dynamics of gut microbiome colonisation during early-life stages is important for understanding the potential impact of microbes on host development and fitness. Evidence from model organisms suggests […]

Diagnosing the Rapid Loss of Outer Radiation Belt Electrons Due To Strong Chorus‐Driven Wave‐Particle Interactions Along an Electron Injection Path
Read more of: Diagnosing the Rapid Loss of Outer Radiation Belt Electrons Due To Strong Chorus‐Driven Wave‐Particle Interactions Along an Electron Injection PathMulti‐spacecraft data demonstrate that intense chorus waves are excited during electron injection events that drive rapid radiation belt electron loss across a limited energy range from ∼100 to 300 keV […]

Rheological control of crystal fabrics on Antarctic ice shelves
Read more of: Rheological control of crystal fabrics on Antarctic ice shelvesIce crystal fabrics can exert significant rheological control on ice sheets and ice shelves, potentially softening or hardening anisotropic ice by several orders of magnitude compared to isotropic ice. We […]

Loss of accumulation zone exposes dark ice and drives increased ablation at Weißseespitze, Austria
Read more of: Loss of accumulation zone exposes dark ice and drives increased ablation at Weißseespitze, AustriaIn recent years, firn and summer snow cover have decreased on Alpine glaciers, exposing larger areas of ice at higher elevations. This reduces albedo and leads to increased melt. To […]
