The global ocean is a significant carbon sink, absorbing about a third of all atmospheric carbon dioxide (CO2) emissions (Gruber et al., 2019).
Hope L. Ianiri, Ph.D.
I am a Research Chemist and Mendenhall postdoctoral fellow at the U.S. Geological Survey, Pacific Coastal and Marine Science Center. My research investigates sedimentary organic carbon stored in critical marine mineral environments.
My research interests broadly include the marine organic carbon and nitrogen cycles and long-term carbon storage in marine environments. At USGS, my research aims to understand the source and bioavailability of organic carbon sequestered in marine mineral host sediments. This is key to determining how this stored carbon could be impacted by potential disturbances and what implications this could have for benthic communities. To do this, I apply a range of geochemical tools, including elemental, isotopic, spectroscopic, and biomarker analyses.
