The flux of nutrients from continents to the oceans sustains oceanic primary productivity and is a fundamental component of the carbon cycle. In most regions of the world’s oceans primary […]
Maritime Antarctica experiences less extreme environmental conditions than much of the Antarctic continent and has further been impacted by considerable warming in recent decades. While inventories exist of macroscopic Antarctic […]
For the first time, a comparison of altimetry-derived snow depth estimates between dual-frequency spaceborne and near-coincident multi-frequency airborne estimates is conducted using data from the recent under-flight of a CryoSat-2 […]
Light-based geolocation can be an effective tool for understanding movements and distributions of free-ranging seabirds, particularly during migrations and long-distance foraging trips. The light levels recorded by geolocators (global location […]
Antarctica’s weather and climate have global impacts, influencing weather patterns, ocean currents and sea levels worldwide. However, Antarctica is vast and complex, and the atmospheric processes that govern its climate […]
Tropospheric ozone depletion events (ODEs) occurring in the Arctic spring are a unique photochemical phenomenon in which the boundary layer ozone drops rapidly to near-zero levels. However, the criterion for […]
Svalbard is host to a range of glacier types with different thermal regimes, behaviors and complex hydrological networks and landforms. Here, we hypothesize that the (H1) surge-type glaciers will host […]
The importance of Antarctic iceberg meltwater for the Southern Ocean has been a strong incentive to include Lagrangian icebergs in ocean and climate models. However, the modeled iceberg thickness has […]
The Antarctic Circumpolar Current (ACC) exerts substantial control on the physical, chemical, and biological properties of the Southern Ocean, playing a key role in modulating the global carbon cycle and […]
Between ~800 and 430 thousand years ago lukewarm interglacials were characterized by lower atmospheric CO2 levels and colder Antarctic temperatures than subsequent interglacials. The Southern Ocean is thought to have […]
Full-thickness ice shelf fractures, known as rifts, create tabular icebergs that can reduce ice shelf extent and thereby jeopardize overall marine ice sheet stability. Low confidence in the scientific understanding […]
Numerical models of energetic electron behavior in the outer radiation belt require descriptions of the wave‐particle interactions across the inner magnetosphere. Quasilinear diffusion coefficients describe gyro‐resonant wave‐particle interactions over large […]
