Interpolation with Barrier

So as shown in pic I have a bunch of stations with water sample data and polygons representing the water in harbor.

The objective is to interpolate data over the water body.

To best simulate peninsula's barrier effect, I understand that I am better off with Diffusion Interpolation with Barriers and/or Kernel Interpolation with Barriers in Geostatistical Analyst Tool.

For those who are experienced in this kind of endeavor,
1. Should I aggregate the polygons first to connect the waters?
2. If I set the polygons as barriers, will it be considered islands instead of waters? With this concern, how should I best specify the parameters for the interpolation tool?

These are some really powerful tools in ArcGIS. I would love to engage in related discussions not limited to this forum.

Will check for updates frequently. Any input is appreciated!
