Definition Letter designation for survey line Replicate survey number time, UTC string in yyyy-mm-dd format time, UTC string in HH:MM:SSZ format Numerical representation of UTC day and fraction of a day in Matlab format Longitude position of measurments. Latitude position of measurements. Conductivity, from primary sensor TS-90, based on International Temperature Scale of 1990 gage pressure of measurment Estimated chl contentration from in-situ fluorometer calculated from transmission accordiing to: Beam attenuation coefficient c = - ( 1 / (path length[m]) * ln ( light transmission [decimal] ) depth calculated from pressure, seawater density, and latitude Temperature after the effects of compression have been removed. Defined as the temperature of a parcel of water at the sea surface after it has been raised adiabatically from some depth in the ocean Salinity calculated according to the "Practical Salinity Scale of 1978" Density anomaly calculated with in situ salinity, potential temperature and pressure=0. sigmatheta = density[kg/m3] - 1000kg/m3. (International Equation of State, Joint Panel on Oceanographic Tables and Standards, 1981) difference between the in situ specific volume (m3/kg) of a parcel and specific volume at the same pressure with S=35 and T=0[celsius]. oxygen concentration from the SeaBird Electronics sensor
