The composition of cometary ices [PDF]
Philosophical Transactions Series A, Mathematical, Physical, and Engineering Sciences, 2017 The chemical composition of cometary ices provides clues for the conditions of formation and evolution of the early Solar System. A large number of molecules have been identified in cometary atmospheres, from both ground-based observations and space, including in situ investigations.

Southern Ocean regime shift: divergent trends in surface phytoplankton community composition using a diagnostic pigment framework [PDF]
Nature CommunicationsPhytoplankton communities in the Southern Ocean (SO) play a central role in regulating global climate and ecosystems through the biological carbon pump (BCP), which is influenced by ocean warming and sea-ice variability.

Thermodynamics of Sea Ice Phase Composition Revisited [PDF]
Journal of Geophysical Research: Oceans, 2019 AbstractPure ice, brine and solid minerals are the main contributors to sea ice mass. Constitutional changes with salinity and temperature exert a fundamental control on sea ice physical, chemical, and biological properties. However, current estimation methods and model representations of the sea ice phase composition suffer from two limitations—in a ...

Ice accretion compositions in ice crystal icing
International Journal of Heat and Mass Transfer, 2023 Ice crystal icing is a major hazard in aviation from the perspectives of aerodynamic deterioration, flight safety and operability. To counter this challenge, existing ice prediction tools require more accurate modeling of sticking efficiency of glaciated ice crystals on heated substrates. As part of the present study, icing wind tunnel experiments have

A method for construction of an energy-efficient ice floating pier in the Arctic using hardened ice [PDF]
E3S Web of Conferences, 2020 This paper presents studies on increasing the ice strength using various additives. It is indicated that addition of wood fiber (artificial composition) and vegetable fiber (natural composition - frozen peat) to ice is an energy-efficient method to ...

Astronomy & Astrophysics, 2023 Context. The subsurface oceans of icy satellites are among the most compelling among the potentially habitable environments in our Solar System. The question of whether a liquid subsurface layer can be maintained over geological timescales depends on its chemical composition.
