Antarctic krill (Euphausia superba) are integral to Southern Ocean pelagic ecosystems. Winters with extensive sea ice have been linked to high post-larval krill recruitment the following spring, suggesting that sea ice plays a critical role in larval overwinter survival.
One of the largest sectors of the Southern Ocean is the Indian Sector, which plays an important role in regulating the Earth's climate and supports a diverse ecosystem. To understand how climate change impacts the environment in this sector…
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.
Using the Davis (68°S, 78°E) lidar, several observing campaigns recently examined the small scale temperature structure and variability in the Antarctic winter upper troposphere and lower stratosphere (UTLS). Lidar measurements of N2 Raman backscatter were obtained over the altitude range of 8…
A Rayleigh-Raman lidar has been operating at Australia's Davis Station in Antarctica since early 2001. The lidar is part of a suite of instruments making measurements of various processes from the lower atmosphere to the edge of space.
