Hi,
use the option ChartLayout -> "Grid" for BarChart3D !

BarChart3D[binorm/Max[binorm],
 BarSpacing -> .5,
 Boxed -> False,
 BaseStyle -> {Medium, FontFamily -> "Arial"},
 Axes -> {False, False, False},
 PlotLabel -> "Field Study",

 ChartLayout -> "Grid",
 ViewPoint -> {1.3, -2.4, 2},
 FaceGrids -> None
]

Unfortunatly, I don't know no no way (other than manipulation of the 
generated Graphics3D expression) to get rid of the two "walls". Histogram3D 
should be the function to be used for this, but the current interface makes 
it too complicated :-(

Greetings from Croatia,
Drago
