Then she braved the cold (-29degC!!) to spend time microtoming the samples. She first tried transmitted light mode on the microscope and thus needed to shave the samples until they were very thin. Later she tried reflected light and was able to keep the samples relatively thick.
The rock and ice mechanics lab at Lamont-Doherty is led by PIs Heather Savage, Christine McCarthy and Ben Holtzman. We are in the process of growing our lab and building our experimental program. Along with a team of postdocs, undergrads, grads, and longtime staff engineer Ted, we are rehabilitating and revamping some of the old equipment and building new rigs for exciting new experiments on both rock and ice. You can follow along with our progress here.

Visitor in the cold room
Early this month Tess Caswell a graduate student from Brown University came to visit us and image ice samples with our brand new, cold room-designated microscope and microtome. She risked strange stares from fellow passengers as she lugged a dewar of liquid nitrogen onto the Amtrak train, through Grand Central, and out to Queens via subway.
