Measuring the acidity in acid mine drainage near coal mine area.

Summary[edit]

Description
Eesti: Pilt on tehtud Teravmägedes, Longyearbyeni linna ümber, kus kivisöe kaevandamise mõjud on looduses, sest igal suvel seguneb lume sulaveega söe kaevandusest pärit happeline vesi, kuigi kaevandamist enam aktiivselt selles piirkonnas ei toimu. Näha on ka kollakat värvi, mis on tingitud rauaühenditest. Pilt on tehtud Arktilise mikrobioloogia kursuse raames välitööde ajal, mil üks kursuse doktorantidest mõõtis ojas pH taset.
English: Picture is taken in Longyearbyen in Svalbard during Arctic microbiology course field work, while PhD student is measuring the acidity in acid mine drainage near coal mine area. Even though mining is not active in that region anymore, the effects are still visible not only in low pH level, but also in the yellowish color from the metals like iron.
