COLUMN TITLES

Column 1: date [Matlab serial date format, i.e. number of days since 00-JAN-0000]
Column 2: date [Unix timestamp, i.e. number of seconds since 01-jan-1970]
Column 3: Pressure at the sea bottom corrected for atmospheric pressuren [Pa]
Column 4: Water temperature [degree_Celsius]
Column 5: Water elevation [m]. Conversion from pressure: water density = 1027 kg.m-3 and gravity = 9.83 m.s-2. Reference datum is WGS84, which is 0.28 m above the MSL calculated for this measurement period.
