In this study, we have investigated short-period ( 1 hr) atmospheric gravity waves (AGWs) in the Arctic mesosphere-lower thermosphere (MLT) region during January of 2014, 2015, and 2016. We used […]
Blowing snow plays a key role in the surface mass and energy budgets of polar regions and can be a significant source of water vapor to the atmosphere. In this […]
Spatial segregation in at-sea distribution is frequently observed in seabirds and can have important implications for conservation and management. Globally, many albatross and petrel populations are declining due to bycatch […]
A dual-modality sensor combining ground-penerating radar and electromagnetic induction for the measurement of sea ice thickness is proposed. Though inductive sensing alone is widely used for ice thickness measurement over […]
Deleterious mutations are ubiquitous in natural populations and, when expressed, reduce fitness. However, the specific nature of these mutations and the ways in which they impact fitness remain poorly understood. […]
The giant warty squid Moroteuthopsis longimana is an important prey of top predators in the Southern Ocean. It is therefore a major link in the pathway of contaminants like mercury […]
Endurance, one of the main vessels of the Imperial Trans-Antarctic Expedition of 1914–17, became stuck and eventually was crushed by sea ice, sinking to the bottom of the Weddell Sea; […]
