Four Square

A research team from WHOI moves out along a ridge above the Koettlitz Glacier in Antarctica. The sun is due north over the Ross Sea, meaning it’s midday. Joint Program student Andrea Burke has her rock hammer out, and WHOI marine chemist Mark Kurz is leading the group toward a rock sampling location. WHOI geologist Adam Soule has just taken a photograph of the patterned ground beneath their feet. Science writer Hugh Powell (second from right) collected the stories.
