    This data set includes two versions: 1.4.2 and 1.4.3. The general circulation ocean model on which the analysis is based uses the Geophysical Fluid Dynamics Laboratory Modular Ocean Model 2.b code, with conventional choices for mixing, etc. The constraint algorithm applied is an extension of optimal interpolation data assimilation, an algorithm that has been widely applied in meteorological numerical weather forecasting. The extension includes changes in the spatial dependence of the statistics and in the assumption of bias in the model forecast. The domain of this analysis extends from 628S to 628N. The main datasets used to constrain the model are the hydrographic data contained in the World Ocean Atlas 1994; additional hydrographic data, satellite, and in situ sea surface temperature; and altimetry from the Geosat, ERS-1, and TOPEX/Poseidon satellites. The historical dataset is sufficiently limited that no attempt has been made to resolve midlatitude mesoscale variability and have limited our attention to the upper 500 m of the water column. The control analysis and analysis experiments begin January 1950 and continue through December 1995. The basic analysis fields, thus, consist of 552 monthly averages of temperature, salinity, sea level, and the horizontal components of velocity.

    The Barcode of Life Data System (BOLD) is an informatics workbench aiding the acquisition, storage, analysis and publication of DNA barcode records. CSIRO Marine and Atmospheric Research (CMAR) contributes to this database, as of May 2008, it has contributed about 1000 species of fish, mostly from multiple samples, along with ~100 species of decapods and ~100 species of echinoderms (marine invertebrates). There is DNA data for a specific gene (COI). The collection of data includes GPS location, date, depth, who collected and identified sample, and some have photos. The samples used in providing the information to the Database from CMAR are housed at the Marine Laboratories in Hobart.

    The CSIRO Global Atmospheric Sampling Laboratory (GASLAB) Flask Sampling Network archive for the atmospheric trace gas hydrogen (H2) concentrations. GASLAB principally analyzes air samples that have been captured at eleven fixed geographic sites and one moving (aircraft over bass strait and Cape Grim), but also includes other sites at various locations globally on a less regular or as needed basis. The flask air sample is analyzed for the 5 atmospheric trace gases Methane (CH4), Carbon Dioxide (CO2), Carbon Monoxide (CO), Hydrogen (H2) and N2O (Nitrous Oxide). Data about the relative concentrations of these are particularly important for Global Warming studies as CO2 and CH4 are the two most effective anthropogenic greenhouse gases; CO and H2 influencing concentrations of the hydroxyl radical (OH), thereby affecting the main sink for atmospheric CH4. H2 is produced in a sequence of reactions following the reaction of OH with CH4. Measurements for H2 concentrations are made through the use of a Gas Chromatograph with a mercuric oxide reduction gas detector “RGA3-1” (R1). There are 6 differant types of flask that are used to store and transport air samples from site and in the labratory:(i) glass 0.5 litre ("G050"), (ii) glass 5.0 litre ("G500"), (iii) glass 0.8 litre ("G080"), (iv) electropolished stainless steel 1.6 litre "Sirocans" ("S160"), (v) glass 2.0 litre, 1 stopcopck ("F", "FF", "FA", "FE", "EP", ALT"), (vi) glass 2.0 litre, 2 stopcocks(“M1”, “S”, “P2”, “TEMP”). Files containing a single species value for each sample are denoted by a filename of the form (XXX_XXXX_event.XXX), for the geographically fixed sites data is also provided in the form of monthly means (e.g. XXX_XXXX_mm.XXX) with all fies being in ascii format.

    The CSIRO Global Atmospheric Sampling Laboratory (GASLAB) Flask Sampling Network archive for the carbon 13 isotope (C13) of atmospheric trace gas carbon dioxide (CO2) concentrations. GASLAB principally analyzes air samples that have been captured at eleven fixed geographic sites and one moving (aircraft over bass strait and Cape Grim), but also includes other sites at various locations globally on a less regular or as needed basis. The CO2C13 measurements are made by concentrating the CO2 from the air sample utilising a 3 step automated cryogenic trapping system connected to a dual inlet stable isotope ratio mass spectrometer (Finnigan MAT252) for analysis. The CO2 and N2O gas chromatography concentrations data for the sample are used for ion corrections on the stable isotope measurements. Alternatively the Cape Grim in situ air sample (cia) which has already had the trapping process applied to it on site, uses the data from the Cape Grim in situ CO2 analyser, with the N2O concentration determined by interpolation from the CSIRO global flask network data. There are 6 differant types of flask that are used to store and transport air samples from site and in the labratory:(i) glass 0.5 litre ("G050"), (ii) glass 5.0 litre ("G500"), (iii) glass 0.8 litre ("G080"), (iv) electropolished stainless steel 1.6 litre "Sirocans" ("S160"), (v) glass 2.0 litre, 1 stopcopck ("F", "FF", "FA", "FE", "EP", ALT"), (vi) glass 2.0 litre, 2 stopcocks(“M1”, “S”, “P2”, “TEMP”). Files containing a single species value for each sample are denoted by a filename of the form (XXX_XXXX_event.XXX), for the geographically fixed sites data is also provided in the form of monthly means (e.g. XXX_XXXX_mm.XXX) with all files being in ascii format.

    The CSIRO Global Atmospheric Sampling Laboratory (GASLAB) Flask Sampling Network archive for the oxygen 18 isotope (O18) of atmospheric trace gas carbon dioxide (CO2) concentrations. GASLAB principally analyzes air samples that have been captured at eleven fixed geographic sites and one moving (aircraft over bass strait and Cape Grim), but also includes other sites at various locations globally on a less regular or as needed basis. The CO2O18 measurements are made by concentrating the CO2 from the air sample utilising a 3 step automated cryogenic trapping system connected to a dual inlet stable isotope ratio mass spectrometer (Finnigan MAT252) for analysis.

    This data file contains global-mean thermosteric sea level anomalies and associated errors between 1950 and 2003, based on the enact 3 data set with Wijffels et.al. (2008) fall rate corrections applied to the eXpendable BathyThermograph (XBT). There are two files, one with yearly averages, the other with three-year running means. The Units are millimetres. For the errors, One-sigma error in the same units as the variables, and the period is 1950 to 2003, relative to 1961 (zero-crossing), the yearly averages are averages over a calendar year. The time in the file is the centre of the year averaged over. Three-year means are also centred on the time shown. and the depth-integrations are 0-100 m, 0-300 m, and 0-700 m. The three-year running means are as plotted in Domingues et.al. (2008), and are recommended as being the best to use.

    The Global Precipitation Climatology Centre (GPCC) dataset containing the global analysis of monthly precipitation on earths landsurface based on in situ raingauge data from 9,343 stations worldwide. Otherwise known as the VASClimO 50-Year Climatology (Ver1.0) with monthly gridded time series precipitation analysis data available for the period 1951-2000 with spatial resolutions of 1.0° x 1.0°. The GPCC is operated by the Deutscher Wetterdienst (DWD, National Meteorological Service of Germany). VASClimO is preferred for analysis of temporal climate variability, in particular the spatial distribution of climate change with respect to precipitation. The GPCC VASClimO product is an input to the IPCC 4AR. The CSIRO version of this dataset has had all years concatenated to form one file and has also been processed to be available as a climatology, anomaly, seasonal anomaly, and coefficient format.
