Definition column required by ODV. 2-letter code for this station name cast type at this station, column required by ODV format is mm/dd/yyyy, column required by ODV time, UTC, in 24 hr format, column required by ODV Longitude recorded by the first ctd sample at the station, if available. If not available, then nominal longitude for this location. East is positive. Column required by ODV: all samples which are to be considered at same station must have the same value in this column. Latitude recorded by the first ctd sample at the station, if available. If not available, then nominal latitude for this location. North is positive. Column required by ODV: all samples which are to be considered at same station must have the same value in this column. estimated depth to the bottom at this station, column required by ODV depth based on seawater density, averaged for points in this bin. Positive is down. year (yyyy) plus day-time as a fraction of a year, ie, half way thru 2005 = 2005.5 longitude of this measurement, recorded by the CTD, if available. If not recorded, then nominal longitude. East is positive. latitude of this measurement, recorded by the CTD, if available. If not recorded, then nominal latitude. North is positive. average seawater pressure, decibar center of the pressure averaging interval ITS-90, based on International Temperature Scale of 1990 Conductivity, from primary sensor voltage, 0 channel, raw data for diagnostic purposes voltage, 1 channel, raw data for diagnostic purposes voltage, 2 channel, raw data for diagnostic purposes voltage, 3 channel, raw data for diagnostic purposes descent rate of the CTD package percent of light emitted by a source reaching a sensor across a path of known length (usually 0.25m) calculated from transmission accordiing to: Beam attenuation coefficient c = - ( 1 / (path length[m]) * ln ( light transmission [decimal] ) Estimated chl contentration from in-situ fluorometer reserved for extra sensor (user-supplied polynomial) 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" sigma-theta. 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]. the number of data lines averaged in this bin
