About me

Tzu-Hao is a PhD student in the department of geological science at Stockholm University. His PhD project is dedicated to unravelling the mystery of Marine Silicate Weathering (MSiW), which was ignored in the past but contributes significantly to Earth's carbon dioxide fixation. Multiple disciplines (elemental abundance, stable isotope, mineral composition and numerical modelling) are applied to the various continental margin sites to study MSiW.

Before PhD studies, Tzu-Hao has a bachelor degree in Oceanography (National Sun Yat-sen University, Taiwan) and a master degree in Oceanography (Institute of Oceanography, National Taiwan University, Taiwan).  After graduation, he has a two-year working experience in food safety (I-MEI Foods Co., Ltd., Taiwan).

Research

His current research interests consist of:

  1. Separation Si-phases of marine sediments using sequential leaching: Applying various acids and bases solution for leaching different Si-phases of marine sediment. Related publication: Huang, T.-H. et al. Sequential extraction of biogenic, authigenic and lithogenic silicas and silicates from marine sediments. in Goldschmidt 2021, Virtual (2021)
  2. What are the Si-reactant and Si-product of MSiW?: Using stable isotope geochemistry and mineral analysis of marine sediments to find out the MSiW's participants.
  3. MSiW's rate quantification: Coupling numerical modelling and Si isotope geochemistry of porewater and sediments to calculate MSiW's rate.
  4. What is the critical factor determining the MSiW?: Documenting the differences of MSiW between various sites using multiple approaches.

His former research projects include:

  • Estimate dietary intake of pollutants (Dioxins and dl-PCBs) and nutrients (EPA and DHA) through pelagic fish from Taiwan's local market.
  • Characterize fluids contents and temperatures using the clumped Isotope compositions and elemental abundances of calcite veins sampled from the Taiwan Chelungpu-fault Drilling Project. Related publication: Huang, T.-H. Fluid temperature and composition associated with displacement of the Chelungpu fault in Taiwan. (National Taiwan University, 2017).
  • Examine isotopic compositions of the planktonic foraminifera collected by plankton tow from the South China Sea.
