Inner Clyde Estuary monitoring buoy, Firth of Clyde

Continuous water quality monitoring equipment was deployed in the inner Clyde estuary adjacent to Govan in 2011. Low dissolved oxygen concentrations are known to occur in the inner Clyde estuary at this location as a result of the decomposition of organic wastes from discharges and urban run off.  

Limited mixing between fresh water and more dense saltwater leads to large differences between the salinity of surface and bottom waters in the Clyde estuary as the less dense fresh water sits on top of the more dense salt water. This can lead to large differences in dissolved oxygen between surface and bottom waters as oxygen removed from the bottom waters by decomposition of organic matter in the sediments is not replaced by oxygen supplied by the river and transferred into the surface waters from the air.

The monitoring buoy data is gathered by SEPA to help it fulfil its statutory duties. We publish it online because we recognise that this information may also be useful for others, but we cannot guarantee its currency or availability. Use of the data is subject to our standard terms and conditions of reuse. The majority of our buoys do not have remote telemetry and so data availability is subject to monthly downloads when the buoys undergo maintenance.
