Glacial geologist Jamey Stutz dates Antarctic rocks 'dropped like breadcrumbs from melting glaciers' to help determine the scale of glacial retreat. Jamey has recently joined the Byrd Polar and Climate Research Center in Ohio as a research scientist in the Polar Rock Repository, having completed his Ph.D at the Antarctic Research Center at Victoria University in Wellington. Jamey says he's excited to be part of the more than 60 year exchange of Antarctic knowledge between New Zealand and America.
