Research in MC&G ranges from the glacial history of the Antarctic ice sheet and the formation of surface films in the upper micron of the ocean to the cycling of carbon through various ocean reservoirs, the history of ocean circulation recorded in the growth bands of coral, and the role of hydrothermal vents and seawater-rock interactions on the composition of the oceans.
