In need of a timeline cleanse - so here are a few memories from my first Antarctic expedition - SIPEX2007. It took place in September, pretty much still winter. That was the point, to go and find a lot of ice.

And we did.

It's also a time when we thought we were going to change the game of high resolution topographic analysis of sea ice using lidar, imagery and computer vision - validated by rigorous ground observations. And use what we found to validate ship and satellite observations...

Good days.

An iceberg corner with the shadow of a helicopter on it. HOw big are Antarctic bergs? Really bigRSV Aurora Australis parked in sea ice at night, all lit up. A stream of light from the ship out to the right is somebody's headlamp"Dragonscale ice" - the first time it was ever observed/ described. A very thick (metres) layer of very small (10-30cm) ice floes formed in very cold, turbelent conditions deep in the pack ice interior
