Hello! My research areas includes, in the early days, CaCO₃ dissolution and sediment diagenesis in sea floor using microelectrodes (O₂, pH and pCO₂) and, since mid-1990s, air-sea exchange of CO₂, carbon cycling, and ocean acidification in coastal oceans and in the Arctic Ocean. I have been a PI for 55 or so research projects funded by NSF, NOAA, and NASA. Please look at my full curriculum vitae for more details.
