Ocean processes at the Antarctic continental slope“, Philosophical Transactions of the Royal Society A, vol 372(2019), 20130047, doi:10.1098/rsta.2013.0047
My contribution (section 2) further studies the salinity biases and biases on the Antarctic shelf of the Heuzé et al. (2013) / paper  models.
We found that CMIP5 models have large regional salinity biases, but found no consistency among models.
Models which have large biases in the deep ocean often have large biases on the shelf too.
Models poorly represent the open ocean and the continental slope, but they have few observations to constrain them.
