Short summary
In ocean models, Antarctic Bottom Water (AABW) formation is frequently misrepresented. Hence, assessing the causes of spurious formation is important to ensure accurate future simulations. Only one of the state-of-art reanalyses investigated showed AABW formation accurately. Spurious formation in the other two products resulted from opening of open ocean polynyas. The relatively accurate AABW formation in one of the products is an important advance in the simulation of deep ocean circulation.
