We quantified dry and wet deposition of dust, nitrogen, and phosphorus over the southwest Mediterranean region (Sierra Nevada, Spain) and assessed its effects on the nutrient status and the chlorophyll a (Chl a) concentration in two high mountain lakes. Atmospheric deposition of particulate matter (PM) and total phosphorus (TP) were mainly associated with dryfall and showed a seasonal pattern similar to that reported for Saharan dust export toward the Mediterranean region, with maxima during… 

Phosphorus loading of mountain lakes: Terrestrial export and atmospheric deposition

We studied the atmospheric deposition of phosphorus (P) forms along an elevation gradient, and its contribution to the total external P loading of lakes in the Tatra Mountains and the Bohemian

Atmospheric deposition as a source of carbon and nutrients to an alpine catchment of the Colorado Rocky Mountains

Abstract. Many alpine areas are experiencing deglaciation, biogeochemical changes driven by temperature rise, and changes in atmospheric deposition. There is mounting evidence that the water quality

Effects of atmospheric deposition on microbial dynamics and composition in two anthropogenically-influenced contrasted coastal sites

The Mediterranean Sea is an oligotrophic basin, while the atmosphere above is affected by continuous emissions of anthropogenic aerosols and episodic Saharan dust events. These atmospheric inputs

Dust mediated transfer of phosphorus to alpine lake ecosystems of the Wind River Range, Wyoming, USA

Abstract Alpine lakes receive a large fraction of their nutrients from atmospheric sources and are consequently sensitive to variations in both the amount and chemistry of atmospheric deposition. In

Significance of atmospheric inputs of calcium over the southwestern Mediterranean region: High mountain lakes as tools for detection

We quantified dry and wet atmospheric deposition of calcium over the southwest Mediterranean region and we assessed its impact on calcium dynamics of two high mountain lakes differing in morphometry

Is atmospheric phosphorus pollution altering global alpine Lake stoichiometry?

Anthropogenic activities have significantly altered atmospheric chemistry and changed the global mobility of key macronutrients. Here we show that contemporary global patterns in nitrogen (N) and

Long-term atmospheric deposition of nitrogen, phosphorus and sulfate in a large oligotrophic lake

Correlations between loading data and various measures of air quality in the basin suggest that dust and smoke are important sources of nutrient loading and in years of high atmospheric loading of inorganic N, deposition may account for up to 6.9% of carbon converted to biomass.
