Observation ID #14490
Date and Time Saturday 12th February 2022 10:25am
Approved Approved

Notes

This sampling took place from fishing pontoon 100m upstream of Stanley Street Bridge due to demolition of bridge. New bridge to be in place September 2022.

 

Royal spoonbills, White ibis, Pacific black duck and ducklings, Little pied cormorant, White faced herons.

 

J.Obst - great water quality and bird observations!  Very distinct salt wedge on the bottom layer which is interesting - shown through Salinity/EC as expected, but also low turbidity down deep due to the clearer nature of sea water vs cloudier freshwater.  Great work!
