Acquiring prism lock: the cover photo

The cover photo for this site shows.. the back of my head, a Leica Viva TS 15, a prism, and a bright yellow, low cost, very effective instrument warming/battery box I’m very proud of! I’m acquiring prism lock using the remote control, before heading out to collect locations on a SIPEX II ice station. The sea ice surveying project was part of my work for the Australian Antarctic Division, and complements my PhD studies. It was a challenging task – nobody knew if the total station would play happily at -20 degrees celcius on drifting sea ice. It performed admirably, and the results will provide much-needed spatial glue for on, over and under ice spatial datasets collected on the voyage. Photo: Polly Alexander
