Dust inputs and bacteria influence dissolved organic matter in clear alpine lakes.
6 páginas, 4 figuras. Remote lakes are usually unaffected by direct human infl uence, yet they receive inputs of atmospheric pollutants, dust, and other aerosols, both inorganic and organic. In remote, alpine lakes, these atmospheric inputs may infl uence the pool of dissolved organic matter, a crit...
