One of the extra jobs on station is that of sea-ice monitor. This involves heading out on the sea-ice and drilling designated GPS locations in the surrounding bays at Casey Station.
This information is then logged and sent to UTAS in Hobart for further analysis. We try to get out and measure the sea-ice depth once a fortnight. Three measurements are taken:
- Snow depth on top of the ice
- Freeboard (distance between the top of the water and the top of the ice)
- Ice thickness
The ice has been growing between 100mm and 200mm per fortnight. The ice at all locations is roughly 1m thick. It is a fun and enjoyable job allowing a few people to get off station to take in more of the amazing sights from a different view point.
