Evolution of Carbon Dioxide Atmosphere and Polar Caps
The long-term variations in the atmospheric pressure and the polar cap temperature of Mars resulting from the obliquity oscillations (presented by W. R. Ward, 1974) are discussed. In performing these calculations, the assumption is made that the atmosphere is in equilibrium with perennial CO2 ice deposits at the north pole, as is proposed by R. B. Leighton and B.C. Murray (1966). If heat transp...
متن کاملComparisons of Observations and Simulations of the Mars Polar Atmosphere
Introduction: Recent advances in algorithms used to process data from the Mars Climate Sounder (MCS) [1] permit the study of the Mars polar atmosphere with unprecedented spatial and temporal resolution and coverage. We have used this improved observational record in comparisons with General Circulation Models (GCM) and reanalysis. To date, limitations in the observations have made more difficul...

in reticulocytes (Fig. 2). The correlation coefficients for GSH/PCV and reticulocyte count for each group on each sample day were not significant when compared with published critical values (13). Elevated GSH/PCV may indicate a unique biochemical response by avian red cells experiencing oxidant stress or a toxic mechanism involving reduced activity of a GSH-dependent enzyme such as glutathione...

متن کاملOcean-atmosphere partitioning of anthropogenic carbon dioxide on centennial timescales
[1] A theory for the ocean-atmosphere partitioning of anthropogenic carbon dioxide on centennial timescales is presented. The partial pressure of atmospheric CO2 (PCO2) is related to the external CO2 input (DSC) at air-sea equilibrium by: PCO2 = 280 ppm exp(DSC/[IA + IO/R]), where IA, IO, and R are the pre-industrial values of the atmospheric CO2 inventory, the oceanic dissolved inorganic carbo...
