We examine recently collected cloud observations made from the surface of the Southern Ocean using W-band cloud radar, ceilometer and a polarization capable lidar. The data were collected as part of several ship- and Macquarie Island-based campaigns between 2016 and 2018.
A Raman depolarization lidar was deployed at Cape Grim, Australia (40.7°S, 144.7°E), at the northern edge of the Southern Ocean from July 2013 to February 2014 from which we determine cloud boundaries, cloud phase, ice virga, and cloud effective top heights.

Human activities in Antarctica pose significant threats to marine ecosystems through accidental fuel spills, primarily as aresult of shipping incidents. This risk is likely to increase due to rises in shipping frequency in the Southern Ocean.
