Joshua is an oceanographer, whose masters focused on determining the amount of carbon dioxide is transported from the ocean’s surface into the deep, by phytoplankton near the Larsen C ice shelf, an area in the Western Weddell Sea of Antarctica. Studying the ocean's physical, chemical, biological, and geological processes is essential to developing effective strategies for mitigating and adapting to climate change. Researching ocean acidification, sea level rise, and the health of marine ecosystems provides vital data for predicting and mitigating climate impacts on marine life and coastal communities.
