Researcher: Key to Understanding Climate Change Could Lie Just Below Ocean’s Surface

Alison BuchanA better understanding of how carbon cycles through the ocean could advance our knowledge of climate change, according to a UT researcher.

From beach shallows to the ocean depths, vast numbers of microbes work together to transform and store atmospheric carbon in the world’s oceans, compounds collectively referred to as dissolved organic carbon (DOC). But studying the connections between those ocean-borne compounds and microbes has been impractical because of their huge number and complexity—until now.

UT researcher Alison Buchan, along with a team of US and international scientists, has identified technological developments that are providing scientists with the analytical tools needed to understand these molecular-level relationships.

Their perspective article appeared March 7 in the Proceedings of the National Academy of Sciences. It focuses on dissolved organic matter in the world’s oceans as a central carbon reservoir in the current and future global carbon cycle.
