From the frontiers of research on ice dynamics in its broadest sense, this review surveys the
structures of ice, the patterns or morphologies it may assume, and the physical and chemical …

It has been shown that sunlit snow and ice plays an important role in processing
atmospheric species. Photochemical production of a variety of chemicals has recently been …

Nitrous acid (HONO) is an important precursor of the hydroxyl radical (OH), the self‐cleaning
agent of the atmosphere and a key species in the formation of harmful photooxidants during …

In several recent field campaigns the existence of a strong daytime source of nitrous acid
was demonstrated. The mechanism of this source remains unclear. Accordingly, in the …

Polar ice sheets hold a significant pool of the world's carbon reserve and are an integral
component of the global carbon cycle. Yet, organic carbon composition and cycling in these …

Atmospheric deposition is the major pathway for removal of organic carbon (OC) from the
atmosphere, affecting both atmospheric and landscape processes. Transfers of OC from the …

This study reports molecular-level characterization of brown carbon (BrC) attributed to water-
soluble organic carbon in six snowpack samples collected from northern Xinjiang, China …

Subsurface microbial oxidation of overridden soils and vegetation beneath glaciers and ice
sheets may affect global carbon budgets on glacial–interglacial timescales. The likelihood …

Defining the control that hydrology exerts on organic carbon (OC) export at the watershed
scale is important for understanding how the source and quantity of OC in streams and rivers …

Snow overlays the majority of Antarctica and is an important repository of dissolved organic
matter (DOM). DOM transformations by supraglacial microbes are not well understood. We …
