JGOFS Water Column Chemical Data Format Document for BEACHBASH cruises December 21, 2005 University of Hawaii at Manoa 1000 Pope Road Honolulu, Hawaii 96822 JGOFS water column chemical data are distributed as ASCII flat files. An entire cruise's data is contained in one file (e.g., bb1.gof contains the data from BEACHBASH-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). For convenience we have also presented some physical data (i.e. CTD pressure, temperature, salinity, etc ...) in the bb*.gof 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 four variables in each row (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 i3 Station Number 9- 16 i3 Cast Number 17- 24 i3 Rossette Position 25- 32 f7.3 Latitude [Degrees North] 33- 40 f7.3 Longitude [Degrees West] 41- 48 f7.1 CTD Pressure (CTDPRS) [Decibars] 49- 56 f7.3 CTD Temperature CTDTMP) [ITS-90] 57- 64 f7.3 CTD Salinity (CTDSAL) [PSS-78] 65- 72 f6.1 CTD Oxygen (CTDOXY) [umol/kg] 73- 80 f7.4 CTD Chlorophyll a (CTDCHL) [ug/l] 81- 88 f7.3 Potential Temperature (Theta) [ITC-90] 89- 96 f7.4 Potential Density (Sigma) [kg/m3] 97-104 f6.1 Bottle Oxygen [umol/kg] 105-112 f7.1 Dissolved Inorganic Carbon (DIC) [umol/kg] 113-120 i4 Alkalinity [ueq/kg] 121-128 f6.2 Phosphate (PO4) [umol/kg] 129-136 f6.2 Nitrate + Nitrite (NO2+NO3) [umol/kg] 137-144 f6.2 Silicate (SiO4) [umol/kg] 145-152 f6.3 Dissolved Organic Phosphorus (DOP) [umol/kg] 153-160 f6.2 Dissolved Organic Nitrogen (DON) [umol/kg] 161-168 f7.2 Dissolved Organic Carbon (DOC) [umol/kg] 169-176 f6.3 Total Dissolved Phosphorus (TDP) [umol/kg] 177-184 f6.2 Total Dissolved Nitrogen (TDN) [umol/kg] 185-192 f6.3 Low-level Nitrogen (LLN) [umol/kg] 193-200 f6.3 Low-level Phosphorus (LLP) [umol/kg] 201-208 f6.2 Fluorometric Chlorophyll a (Chl a.)
