Dee Estuary Station WC
This station is located within the Welsh Channel of the Dee Estuary, Liverpool Bay. It is one of two stations repeatedly visited by the Proudman Oceanographic Laboratory (POL) in the Dee. All activities at this site occurred within a box bounded by co-ordinates 53.371°N, 3.31791°W at the north-east corner and 53.36642°N, 3.33817°W at the south-west corner. Typical depth ranges encountered within the box are 7 m - 17 m.
POL activites can be separated into two groups. These are (i) repeat CTD profiles over tidal cycles; (ii) mooring deployments.
