Information on nutrient data and files : "For nutrient data including averages, replicates" and quality flags - See file 9603nuts.csv . For description of methods used to analyze "nutrients, list of raw data files, description of quality flags and" comments on data - See file 9603nuts.txt . "For data, methods, depth profiles, comments etc.- See excel file" 9603nuts.xls - This is the main source file. "Raw data files : 960716.aaz, 960717.aaz, 960718.aaz (.anz and .xls files" with same names also); 9603nuts.wk3 Samples were frozen onboard ship using a quick freezer and stored in a -20 deg C freezer until analysis at IOS. The dissolved oxygen and bottle salinity data are from merging the nutrient data with the .hyd files. See the .hyd files for more detail on the dissolved oxygen analysis. Any changes necessary to the oxygen or bottle salinity must also be made in the .hyd files for consistancy. See the .hyd files for details on the oxygen analysis. "Temperature, salinity and transmissivity in this file are from the down" cast (.ctd files)associated with the upcast (the bottles were tripped on the upcast). The files were merged using an interpolate merge scheme.
