Highlights
Subtropical and Subantarctic water masses connect habitats throughout the shelf.
Habitat connectivity influences ocean productivity north of Akaroa.
δ15N and δ13C isoscapes are influenced by nutrient availability and coastal advection patterns.
δ15N and δ13C isoscapes vary spatially but showed small temporal variability.

Ecosystem connectivity: tracking biochemical fluxes to inform EBM
We traced the fate of water and sediments from land through coastal food webs, evaluating connections between coastal and deep sea habitats, and identified the effects of key coastal developments (such as aquaculture) on food web connectivity.
