abyssal water mass of the world ocean by volume, is formed by the overflow of dense waters produced along continental shelves around Antarctica. This water mass is a key component of the global meridional overturning circulation (MOC) [1]. Although the basic mechanisms involved in AABW production are fairly well understood, its actual formation process is less clear, compromising our ability to accurate parametrize such process in climate models. This is an important step towards improving the accuracy of these models [2]. Antarctic overflows seem to differ from other systems such as the Mediterranean and Red Sea outflows, since the former lead to abyssal water production while the
