Antarctica – Glacial Ice Melting

Our goal is measure the oxygen and hydrogen isotopic composition of the Pine Island Bay, Amundsen Sea, Ross Sea, and Terra Nova Bay to understand the impacts of glacial melt in western Antarctica.

As anthropogenic climate change becomes more pronounced, concern regarding the state of the world’s ice sheets has been growing. Of particular concern are the Greenland ice sheet and the West Antarctic ice sheet, both of which have exhibited significant mass loss over the past few decades. If the two ice sheets were to fully collapse, they could be responsible for up to 15m of global sea level rise (roughly equal parts from both). This sea level rise would not only pose serious problems for coastal settlements, but cause serious changes to ecosystems, and could profoundly alter the Earth’s ocean circulation.
