The nitrogen interpolation showed a generally increasing trend from North to South throughout the Strait of Georgia. With slightly increased values near the Iona Vancouver Wastewater treatment plant and the Fraser River. The amount of nutrients in the Fraser River due to the presence of the, and the Iona plant relative to natural sources is however unknown.

Phosphorus also generally increased towards the South end of the Strait. However both nitrogen and phosphrous were particularly high in the single southern most point in our data, which likely caused more extreme values than would actually be expected.

Silicon in the Strait tended to be higher in the South-western part of the Strait.

Chlorophyll-a, by visual analysis is best predicted by either the silicon limited or equal weighted model, and least well predicted by the phosphorous limited regime.
