The tide gauge at Port Ellen is sinking. This is because the quayside has been gradually collapsing since 2005. The TGI are aware of the problem and intend to re-site the gauge.

The measuring system at Port Ellen has had to be relocated due to the harbour wall subsiding. The new location is 2m from the original location and the measuring system is mounted on steel piling. A mid-tide sensor has also been added and levelling completed. Values are Full tide sensor -570mm ACD Mid-tide sensor +475mm ACD All other parameters remain the same.
