Our new paper on modeling Heinrich Events was just published in Nature! Link to Paper This work was done in collaboration with Professor Jeremy Bassis (CLASP, U of M).
We propose a new mechanism to explain Heinrich Events involving subsurface warming eating away at the foot of an ice stream in the Hudson Strait, causing dramatic retreat. The new element we incorporate is the response of the solid earth to the repeated regrowth and removal of the ice stream. The rebound of the bedrock modulates the timescales of regrowth and can help explain why Heinrich Events only occur during certain Dansgaard-Oeschger cycles.
