Yesterday we did a transect along the face of the glacier. Every 15 minutes we fired an XBT down to measure temperature, pinged the bottom of the ice shelf with our multibeam bathymetric mapper, used the radar to get the distance from the ice shelf, and used a sextant (old school!) to measure the angle the ice shelf fills in our field of view. With a bit of geometry we now have a rough estimate of the height and draft of the ice shelf. The temperature data crosses the boundary below the ice shelf draft, and we can see how the open bay interacts with the water under the shelf.

 In other news, I think tomorrow is the half-way point of the cruise. For those of you out there anxious to see those of us down here once again, you are beyond half-way. We left you four or five days before the cruise began and will see you much sooner after it has ended.
