  Cross-field neoclassical transport of heat, particles and momentum is studied
in sharp density pedestals, with a focus on isotope and profile effects, using
a radially global approach. Global effects -- which tend to reduce the peak ion
heat flux, and shift it outward -- increase with isotope mass for fixed
profiles. The heat flux reduction exhibits a saturation with a favorable
isotopic trend. A significant part of the heat flux can be convective even in
pure plasmas, unlike in the plasma core, and it is sensitive to how momentum
sources are distributed between the various species. In particular, if only ion
momentum sources are allowed, in global simulations of pure plasmas the ion
particle flux remains close to its local value, while this may not be the case
for simulations with isotope mixtures or electron momentum sources. The radial
angular momentum transport that is a finite orbit width effect, is found to be
strongly correlated with heat sources.
