where:
- ST = TEMPPR01 = Sea Temperature
- LT = CTLGPR01 = Data Logger Ambient Temperature
- SP = PRESPS01 or PRESPS02 = Sea Pressure
- AP = CAPHSL01 = Atmospheric Pressure
- SSP = PRSTPS01 or PRSTPS02 = Sub Surface (total) Pressure
- B
- T = CBTASS01 = Barometric Temperature
Note: The '03 1994 - 01 1995' data file consists of data sampled at 60 minute and 15 minute intervals. The sample interval is 60 minutes until (1994)308: thereafter 15 minutes.

Quality Assessment
All data have been tidally analysed and constants and residuals checked. Records have been visually inspected for spikes and timing shifts. During the winter months, the sea temperature measurements hardly vary, possibly due to ice.
