• Maunalua Bay, Oʻahu, Hawaiʻi: Submarine groundwater discharge drives biogeochemistry in two Hawaiian reefs

    Examined changes in carbonate system parameters due to groundwater discharge and biological processes (calcification-dissolution and photosynthesis-respiration) 
     

  • Maunalua Bay, Oʻahu, Hawaiʻi: Sources and spatial variability of groundwater-delivered nutrients

    Utilized a multi-tracer approach, consisting of C, N, and O stable isotopes in water as well as groundwater modeling, to detect wastewater signatures in groundwater emanating from a coastal aquifer on Oʻahu with a high-density of OSDS
