Ice-age atmospheric concentration of nitrous oxide from an Antarctic ice core

Nature, 1992
INCREASING anthropogenic emissions of greenhouse gases are expected to influence the Earth's climate, but the mechanisms for this are not yet fully understood. One way to determine the effect of such gases on climate is to study their atmospheric concentrations during periods of past climate change, such as glacial to interglacial transitions. Previous

The Concentration of Molecules on Internal Surfaces in Ice

The Journal of Chemical Physics, 1951
In this paper the experimental expression for the ``local conductivity'' of ice is given. This expression has two terms, one of which has already been discussed and brought into close relation with the structure of ice, that is, with its heat of sublimation and its lattice constant.

The Origin and Concentration of Ice Crystals in Clouds

Bulletin of the American Meteorological Society, 1985
Abstract Ice crystals in supercooled clouds may form upon ice nuclei, or they may arise through secondary processes. Two of these secondary ice “multiplication” mechanisms are discussed in some detail: the rime-splintering process and the mechanical fracture of ice particles.

Ice Crystals Agglomerated in Freeze Concentration

1994
Freeze concentration is required to produce large ice crystals in order to reduce the loss of solutes adhering to the surface of the ice crystals removed. We examine here if large agglomerated ice crystals would be produced from a lactose solution in a common batch crystallizer with an inner heat exchanger. Large agglomerated ice crystals (ca.

Methods of measurement of ice nuclei concentrations

pure and applied geophysics, 1965
The actual methods for counting ice nuclei are compared. It appears that the mixing chamber method is most valid.

A Note on the Determination of Sea Ice Concentration

Journal of Offshore Mechanics and Arctic Engineering, 1991
Abstract An argument is presented for the inclusion of diffusive effects in the equation governing the redistribution of sea ice. An ice concentration equation including diffusion is derived through Reynold’s averaging. This advection-diffusion equation is solved using the Eulerian-Lagrangian time-splitting technique, which affords both ...

Ice Nucleus Concentrations in Remote Areas

Journal of the Atmospheric Sciences, 1973
Abstract Concentrations of ice nuclei have been measured in aerosols sampled by pairs of membrane filters mounted high on the forward mast of a ship making almost continuous voyages during the years 1969–72 over the half of the Southern Hemisphere centered on Australia.

A Lunar Influence on Ice Nucleus Concentrations

Nature, 1963
RECENT papers by Bradley, Woodbury and Brier1 and by Adderley and Bowen2 have shown a remarkable relation between the phase of the Moon and precipitation.

Sensors for contactless estimation of ice concentration in "ice slurry" fluids

2014
This paper deals with the problem of estimating the ice fraction in ice slurry fluids flowing into the pipes of industrial refrigeration apparatus based on secondary refrigerants. Such measurements must be performed in a non invasive way and the sensors must face with severe environmental conditions.
