Modelling nutrient dynamics in cold agricultural catchments: A review
2020, Environmental Modelling and SoftwareIncreasing aeolian dust deposition to snowpacks in the Rocky Mountains inferred from snowpack, wet deposition, and aerosol chemistry
2016, Atmospheric EnvironmentCitation Excerpt :Drought can cause increases in dust generation as well, due to its effect on soil moisture and vegetation coverage (Prospero and Lamb, 2003; Munson et al., 2011). Studies in France, Italy, and Switzerland have documented high pH, Ca2+, and alkalinity concentrations in “red” rain and snow from southerly storms tracking from the Sahara Desert, and the distinctive chemistry has been attributed to aeolian dust entrained by desert winds (Loye-Pilot et al., 1986; Schwikowski et al., 1995; Delmas et al., 1996; Rogora et al., 2004). Similar chemistry in rain and snow in the Rocky Mountains and Tien Shan (Asia) has been attributed to aeolian deposition as well (Williams et al., 1992; Clow and Ingersoll, 1994; Clow et al., 2002; Dong et al., 2009; Rhoades et al., 2010; Brahney et al., 2013).
Impacts of Aeolian dust deposition on European forest sustainability: A review
2012, Forest Ecology and ManagementCitation Excerpt :While Aeolian dust contained eighteen percent of calcite at the beginning of the experiment, no calcite has been found in the residual dust at the end of snow melting, suggesting a total dissolution of calcite from Sahara. They carried out another experiment with the aim of calculating dissolution rates under controlled conditions and found out that Ca release reached 2 and 3 g m−2 day−1 at pH 4.80 and 4.35, respectively (Delmas et al., 1996). This is much higher than earlier results focusing in the French Alps: Deangelis and Gaudichet (1991) computed a particulate Ca release of 6.7 10−4 g m−2 day−1, for which 94% were found out to come from Sahara, after analysis of a 70 m long ice core drilled in the Mont Blanc covering the period 1955–1985.

2009, Chemical GeologyCitation Excerpt :Elements that are soluble and/or exchangeable may quickly become available for biological uptake, chemical reactions, or export. Delmas et al. (1996) studied the chemistry of snow cover and melt-waters in France and found that Saharan dust that had accumulated in the snowpack quickly weathered releasing base cations, which raised the pH of the melt-waters. Similarly, surveys of snowpack and precipitation chemistry in the Rocky Mountains revealed patterns in snowpack solute chemistry and alkalinity attributable to dust inputs (Turk et al., 2001; Clow et al., 2002), which may influence stream chemistry in this region (Campbell et al., 1995; Clow et al., 1997).
