First time poster, not sure if this is the right forum, but I'm working on an independent project and I think I have bitten off more than I can chew.  My  intentions were to create a 3D profile of anoxic water concentrations in a local lake.  I know that the water decreases in oxygen concentration with depth.  I have all of the data that I need, currently as multiple points throughout the water column that share XY coordinate data.

My problem is that I want to interpolate a surface between all of the hypoxic to anoxic points that shows oxygen concentrations throughout the profile and I only have experience doing this with data of the same depth.  I've already used the IDW and Kriging tools on all of the points and I'm fairly certain what I came up with is wrong.

Is there a way that I can use depth points individually to create a 3D surface to show regions of anoxia?  The layer doesn't have to show differences in concentrations, only that the area within the surface is anoxic.

I'm not entirely sure this is doable, let alone decipherable; regardless, thanks for any and all help in advance!
