MOCNESS CTD variable names and units vs. GLOBEC Thesaurus Pressure was sometimes stated as debars, sometimes as millibars. It was always in decibars. Pressure (unknown units): these are decibars as are all measurements. CH125 - 8/75 Pressure (millibars): KN65 ? 4/77 [added comments to .nm files that this is error, should be decibars. njc] Pressure (decibars): KN53 -11/75 KN62 [added comments to .nm files that this is error, should be decibars. njc] EN11 ? 8/77 KN71 ? 11/77 [added comments to .nm files for mocs 104-117 that this is error, should be decibars. njc] MAQUI75 (Polloni) (for Chain-125), probably also AT85, KN53 Date: day, month, year (eg. 18 8 75 = 18Aug1975)) Time: hours, comma, minutes Pressure in millibars??? - no 6 calibration constants 1.

GLOBEC Thesaurus: cast = cast number cond_ctd = CTD conductivity, in mmho/cm cruiseid = cruise identifier, e.g. en9402 R/V Endeavor cruise 9402 depth_w = water depth, in meters inst = instrument used to collect or process data lat = latitude (south in negative), in decimal degrees lat_begin = latitude at starting time of measurement (south in negative), in decimal degrees lat_end = latitude at end time of measurement (south in negative), in decimal degrees lat2 = alternate (secondary) latitude (south in negative), in decimal degrees net = net number o2 = oxygen in milliliter per liter (Contact the DMO for units verification. These units are subject to change. press = depth of sample reported as pressure, in decibars press_bar = barometric pressure, in millibars sample = sample identifier or number ship = name of the ship or vessel (See also platform.) station = consecutive station number temp_ctd = CTD temperature, in degrees C (see ref. 2 below) temp = temperature, in degrees C [ITS-9- Temperature Scale, Sea-Bird Electronics, Inc., Application Note No. 42. Revised - November 1996. The linear relationship between the ITS90 (T90) temperature standard and the IPTS68 (T68) standard is T68 = 1.00024 * T90.] time_utc = GMT time, using 2400 clock format. Use time_utc for future data sets. tow = tow number wind_speed = wind speed, in m/s year_gmt = GMT year, e.g. 1995. Use year_utc for future data sets. year_local = local year, e.g. 1995 year_utc = UTC year, e.g. 1995 yrday_gmt = GMT day and decimal time, as 326.5 for the 326th day of 1995, or November 22, 1995 at 1200 hours (noon). Use yrday_utc for future data sets. yrday0_gmt = GMT day and decimal time, as 325.5 for the 326th day of 1995, or November 22, 1995 at 1200 hours (noon). Use yrday0_utc for future data sets. yrday_utc = UTC day and decimal time, as 326.5 for the 326th day of 1995, or November 22, 1995 at 1200 hours (noon) yrday0_utc = UTC day and decimal time, as 325.5 for the 326th day of 1995, or November 22, 1995 at 1200 hours (noon) yrday_local = local day and decimal time, as 326.5 for the 326th day of 1995, or November 22, 1995 at 1200 hours (noon) yrday0_local = local day and decimal time, as 325.5 for the 326th day of 1995, or November 22, 1995 at 1200 hours (noon)
