Field trip to Aqua de Ney

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…

Field trip to Oman

Field trip to Oman

This has been the first field study of my Prometheus project. A week-long campaign searching for alkaline water sources in remote parts of the Sultanate of Oman. The trip was organized by my friend and colleague from the University of Bremen, Professor Wolfgang Bach. In this country of the Arabian Peninsula the rocks of the deep mantle of the planet emerge to the surface moved by forces derived from the pushes of the tectonic plates…

Field trip to Dallol

Field trip to Dallol

The field trips to Dallol have been successfully performed in January 2016 and January 2017. We have collected samples of liquid, gases, air and air particles, etc… and make numerous in-situ measurements of physical and chemical variables such as pH, temperature, pressure, salinity, conductivity, oxygen, redox, visible spectra, etc… The aim of this project is to perform: A rigorous study of the hydrochemistry of the brines including the analysis of the organic compounds and gases. …

Field trip to Malaga

Field trip to Malaga

This field trip of Prometheus project in search of alkaline systems was near its base; at the alkaline springs related to serpentinized peridotites in Malaga province. We visited several methane-rich and hyper-alkaline spring sites within Ronda peridotite massif (La Hedionda, Fuente Amarga Spa Tolox, Fuente Alfaguara, Fuente Amargosa, Baños del Puerto and Baños del Duque). Getting access to the spring sites included “negotiations” with spa owners and local farmers as some of the sites were…
