Progress Code: completed Statement: Further information about the quality of these data are available in the readme file and the pdf report contained in the download. Taken from the readme file: * The following CTD 2 dbar data are suspect (not removed from the data files) (this same information is in the file sussctd.dat): stn parameter pressure (dbar) comment --- --- --- --- 4 oxygen 4-18 transient error at the start 5 oxygen 4-102 transient error at the start 15 oxygen 3768 fouling after bottom contact 47 oxygen 200-2000 maybe inaccurate by up to ~2umol/l due to lack of bottle samples 64 oxygen 250-1700 reduced accuracy due to small number of bottle samples * The following bottle oxygen values are suspect (out by ~3-5 umol/l, not removed from the data files) (this same information is in the file sussox.dat): stn bottle --- --- 16 16 19 9 36 1 38 11 66 1 * Suspect nutrient values are listed in the file sussnut.dat * Bad salinity bottle samples are listed in the file badsalbtl.dat * For station 15, all upcast CTD burst temperature, conductivity and salinity data have been removed from the bottle data file - data are bad, due to fouling from bottom contact at the bottom of the cast. * The complete data report is in the file a0803_a0806.pdf Taken from the accompanying report: Oceanographic measurements were collected aboard the Aurora Australis on cruise au0806 (voyage 6 2007/2008, 22nd March 2008 to 17th April 2008). This cruise completed the CASO oceanographic program begun on the CEAMARC cruise (au0803, voyage 3 2007/2008), with a full occupation of the SR3 transect between Antarctica and Tasmania. CASO program objectives were: 1. to measure changes in water mass properties and inventories throughout the full ocean depth between Australia and Antarctica along 140oE (the CLIVAR/WOCE repeat section SR3), as part of a multi-national International Polar Year program to obtain a circumpolar snapshot of the Southern Ocean in austral summer 2007-8; 2. to estimate the transport of mass, heat and other properties ...
