We have been back on the water this week in Brightlingsea, checking our novel oyster spatting discs and conducting a bathymetric survey of the harbour extents for Brightlingsea Harbour Commissioners.  

As you may remember our discs were taken out of the water back in October 2020 (https://exo-env.co.uk/sif-oyster-update/ ) to determine prewinter colonisation, particularly focusing on the presence of native flat oysters (Ostrea edulis). Results from the autumn showed an encouraging array of different marine organisms inhabiting our discs from Oysters to Mollusca!

Take a look at our video below, where Izaak explains more about the project and SIF:

This most recent check was to determine winter mortality and to determine the health of organisms inhabiting our discs before the forthcoming growing season.

Have at look at the below photos from our latest check.

We were back in Brightlingsea a few days later to conduct a bathymetric survey. This is an annual occurrence and will help inform the harbour of any accumulation of sediment that has occurred over the winter period to help them plan in future dredging operations in the summer months.  

This is a critical exercise to keep waterways at a safe navigable depth and to keep access open to the Port of Brightlingsea to continue to receive large cargo ships, contributing a key economic service to the town of Brightlingsea and wider area.
