I am a marine biogeochemist studying how material and chemical elements are cycled through marine and coastal ecosystems. My research focuses on the carbon cycle in systems such as coral reefs, mangroves, seagrass beds, and calcium carbonate sediments. I am interested in the role that these ecosystems play in the global carbon cycle and how they will be affected by climate change. Most of my work involves making seawater chemistry measurements in the field using state-of-the-art technology, with a focus on carbon dioxide, methane, total alkalinity, oxygen, and submarine groundwater discharge. By measuring these parameters we can get a better understanding of where and how carbon moves between the land and sea.
