Welcome to iGOS4M
iGOS⁴M is an online database of mercury stable isotopes and is an official isotope chapter of GOS⁴M, formally known as the Global Observation System for Mercury, which aims to support the UNEP’s Minamata Convention on Mercury.
Over ~7600 mercury isotope results are compiled from the published literature (Reference) and include biotic (plankton, invertebrate, fish, bird, whale, penguin, human etc) and abiotic samples (rock, ore, sediment, soil, peat, snow, precipitation etc) from the atmosphere, forest, polar regions as well as freshwater and marine ecosystems. Samples from industrial facilities, mercury mining sites, and contaminated/urban regions are also included in the database.
The initial data compilation and the application of mercury isotope data for evaluating the effectiveness of the Minamata Convention on Mercury was reported in Kwon et al (2020) in Earth-Science Reviews. With the collaboration with international steering committee, iGOS⁴M was formally launched in 2022 and integrated into GOS⁴M.
iGOS⁴M is funded and operated by the PI (Sae Yun Kwon) and graduate students (Hoin Lee, MoonKyoung Cho) of the Environmental & Health Assessment Laboratory at Pohang University of Science and Technology (POSTECH).

Rationale
iGOS⁴M has a number of specific objectives (but not limited to the following):
1) Organize peer-reviewed mercury stable isotope data into a single online open access database
2) Broaden the application of mercury stable isotopes for scientific research
3) Support the use of mercury isotope data for the effectiveness evaluation and global monitoring of the Minamata Convention on Mercury and other decision-making processes

Data use
We kindly ask you to cite “iGOS⁴M” when using the database for publication, academic/funded projects, and/or decision-making.
How to participate
We encourage you to share and upload your mercury isotope data to enhance the use, application, and visibility of your scientific work. Please contact Sae Yun Kwon via email (saeyunk86@gmail.com) to receive instructions on how to upload your data.
