#Champagne Pool is one of several hot springs in Waiotapu, New Zealand. Visible in this picture as a cream-colored, raised surface is a rim of sinter, an incrustation deposited by #geothermal activity. Orange sinter lies just below the water’s surface and is rich in arsenic, antimony, thallium, #mercury, #gold, and #silver. The sinters in Champagne Pool are full of microbes, likely #bacteria or archaea that do not use #oxygen. #PhotoOfTheDay #science #geology #elements 📷 Getty
