BEACH Water Column Chemical Data Format Document April 11, 2007 University of Hawaii at Manoa 1000 Pope Road Honolulu, Hawaii 96822 BEACH water column chemical data are distributed as ASCII flat files. An entire cruise's data is contained in one file (e.g., hot1.gof contains the data from HOT-1). Note that these files contain all of the chemistry data. The details of the analytical methods used to determine all of the parameters listed here can be found in the Hawaii Ocean Time-series Program Data Report(s). It should also be noted that both DOC and pH analytical protocols have changed causing offsets in the the temporal data sets. The DOC protocol changed from the persulfate oxidation (HOT 1-27) to the high-temperature platinum catalyzed oxidation (HOT 44- present). The pH was intially analyzed by the electrode method and calibrated against NBS scale (HOT 23-32), during 1992 the pH was analyzed by the spectrophotometric method and the pH calculated on the "total scale" (HOT 33-present). For convenience we have also presented some physical data (i.e. CTD pressure, temperature, salinity, etc ...) in the hot*.gof files. A complete description of the physical data for each bottle trip presented in this file can also be found in the appropriate hot*.sea files. Please refer to the Readme.water.woce file for the format description of those files. The files are self-explanatory; one column is written for each measured parameter. Missing data are filled with -9. A five-line heading labels each column. Variables having asterisks in their heading have a quality flag associated with them. These quality flags are concatenated as a quality word which is listed as the last ten variables in each row (six or seven flags per variable). The values each digit can assume and their meanings follows: Quality Indicators: Flag Meaning 1 not quality controled 2 good data 3 suspect (i.e. questionable) data 4 bad data 5 missing data 9 variable not measured during this cast Data Record Format: Column Format Item 1- 8 i6 Station Number 9- 16 i3 Cast Number 17- 24 i5 Rossette Position 25- 32 i5 Replicate Number 33- 40 f7.1 CTD Pressure (CTDPRS) [Decibars] 41- 48 f7.4 CTD Temperature CTDTMP) [ITS-90] 49- 56 f7.4 CTD Salinity (CTDSAL) [PSS-78] 57- 64 f7.1 CTD Oxygen (CTDOXY) [umol/kg] 65- 72 f7.4 Potential Temperature (Theta) [ITC-90] 73- 80 f6.3 Potential Density (Sigma) [kg/m3] 81- 88 f7.4 Bottle Salinity [PSS-78] 89- 96 f5.1 Bottle Dissolved Oxygen [umol/kg] 97-104 f6.1 Dissolved Inorganic Carbon (DIC) [umol/kg] 105-112 f6.3 pH [either TOT25 or NBS25] 113-120 i4 Alkalinity [ueq/kg] 121-128 f5.2 Partial Pressure of Carbon Dioxide (pCO2) [uatm] 129-136 f6.2 Phosphate (PO4) [umol/kg] 137-144 f6.2 Nitrate + Nitrite (NO2+NO3) [umol/kg] 145-152 f6.2 Silicate (SiO4) [umol/kg] 153-160 f6.2 Dissolved Organic Phosphorus (DOP) [umol/kg] 161-168 f6.2 Dissolved Organic Nitrogen (DON) [umol/kg] 169-176 f7.2 Dissolved Organic Carbon (DOC) [umol/kg] 177-184 f6.2 Total Dissolved Phosphorus (TDP) [umol/kg] 185-192 f6.2 Total Dissolved Nitrogen (TDN) [umol/kg] 193-200 f6.2 Particulate Carbon (PC) [umol/kg] 201-208 f7.3 Particulate Nitrogen (PN) [umol/kg] 209-216 f5.1 Particulate Phosphorus (PP) [nmol/kg] 217-224 f6.1 Low-level Nitrogen (LLN) [nmol/kg] 225-232 f6.1 Low-level Phosphorus (LLP) [nmol/kg] 233-240 f6.2 Low-level Silica (LLSi) [umol/kg] 241-248 f6.2 Fluorometric Chlorophyll a (Chl a.)
