Published datasets

In the spirit of FAIR (findable, accessible, interoperable and reproducible) data principles, I have two published datasets on HydroShare:

 

Oxygen and hydrogen isotopes in streams and precipitation and young water fractions across the Andes mountains and Amazon floodplain

 

and

 

Stable isotopes of water and seasonal origin indices of precipitation, stream, lysimeter and plant xylem waters

Each of these datasets is associated with a published paper (linked above and within the dataset metadata)

What happens to sulfate released from sulfide mineral oxidation?

Burt et al., 2021 Geology:

https://doi.org/10.1130/G48997.1

 

Sulfide mineral such as pyrite (fool's gold!) are fascinating to study for a few reasons: first, they react faster than many other common minerals. Second, when they react with water and air, they create sulfuric acid. The sulfuric acid produced from sulfide minerals can break down other minerals - when the sulfuric acid reacts with minerals that contain carbon, the minerals release carbon into the atmosphere.

 

As humans burn fossil fuels and alter Earth's natural carbon cycle at a rapid pace, researchers in earth sciences are interested in how carbon moves between rocks and the atmosphere. Sulfide mineral oxidation is just one example of a (bio)geochemical reaction that can mediate carbon transfers between rocks and the atmosphere. 


My paper in Geology (Burt et al., 2021) explores the fate of sulfate produced from sulfide mineral oxidation in the Peruvian Andes mountains. What happens to the sulfate after it is released from sulfide mineral oxidation is important for the carbon cycle implications of this (bio)geochemical reaction.
