Project information
Project aim
Antarctic Bottom Water is a major component of the global thermohaline circulation, and as such, plays a key role in controlling Antarctic and Southern Ocean climate. Our knowledge of the variability and stability of Antarctic water masses remains limited. The objective of this study is to better understand the variability, stability, and long-term change of Antarctic Bottom Water (AABW) using state-of-the-art climate models in conjunction with the best available observations. The project outcome will be a better understanding of how AABW properties and formation rates vary naturally and when forced by climate change.
