Field trip to Aqua de Ney

From 8th-14th August we carried out a field trip to Aqua de Ney Spring , an unusual spring in northern California. Aqua de Ney has the highest reported silica concentration (>4000 pm) and pH value (~11.9) in a natural spring. We collected water from these springs, measured in situ the pH and ex-situ silica concentration. Then, we performed experiments with these waters finding that they react with metals to form silica biomorphs and silica gardens (metal silicate hydrate membranes). The findings are being presented in different Conferences and have been recently published in Science Advances.

An article has also been published in the Planetary Society magazine.
