It just so happens to be St. Patrick’s Day and I’m in Ensenada, giving my talk called:

A song of Ice and Fire and CO₂: linking seafloor volcanism and CO₂ efflux during the deglaciation

This is to be my first “formal” discussion of these results. Very excite!

The modern increase of greenhouse gases (such as carbon dioxide) will affect our oceans and climate in sometimes dramatic and unexpected ways.
But it doesn't have to be entirely unexpected!

My work seeks to identify, better understand, and ultimately predict these future changes in two general ways:
(1) by studying the "natural" variability of modern ocean biology, chemistry, and physics that guide the air-sea partitioning of carbon dioxide

(2) by reconstructing past ocean conditions that help reveal the inner workings of planetary processes.

Number (1) takes me out onto the ocean to make measurements and collect seawater samples and (2) is accomplished using a variety of geological archives such as ocean sediments and corals. We need to use these "proxy" records because our ocean observations are not long enough to show significant changes associated with the current buildup of greenhouse gases.
