Our recent field trip to Yinyang Sea in northern Taiwan was a great success! This fascinating acid mine drainage environment, where stream water with high metal concentrations mixes with seawater, creating Fe oxyhydroxide precipitates, provides a unique setting for isotope research. Our MISO team, along with Brandon Stephens's team, collected samples to study metal isotopes and organic chemistry in this dynamic system. It was a fun and productive day with dramatic changes in chemistry!

An umbrella is crucial for water filtration under the scorching sun.
The upstream water is crystal clear before it is contaminated by acid mine drainage.
Nice view, big smiles, and a low pH waterfall!
