Geochemical, microbial and 14C data on remediation of petroleum hydrocarbons in Antarctica. This record is part of ASAC project 1163 (ASAC_1163). Microcosm study using Old Casey petroleum hydrocarbon contaminated sediment investigating the effect of temperature on biodegradation. The experiment was performed over a temperature range of -2 to 42 degrees. The experiment was run over 40 days. Degradation was traced by radiometric methods and total aliphatic hydrocarbons were measured by gas chromatography. Radiometric data in file radiometric_99.xls, Gas Chromatography data in file gc_99.xls. The radiometric spreadsheet is divided up as follows: CALCULATIONS is how much nutrients, water, radioactivity was added to the sediment. SUMMARY is what went into each microcosm flask. %DPMVRST are recovery graphs of individual flasks. AVERAGE RECOVERY and FIRST ORDER are graphs. -2A,-2B etc are the raw data for each flask. The number refers to the temperature, the letter refers to the replicate. The gc_99 spreadsheet is divided up as follows: MicroN2B, MicroN2C etc is the raw gas chromatography data, peak areas, heights, amount extracted. This spreadsheet uses the same codes as the radiometric spreadsheet in the metadata record entitled: 'Mineralisation results using 14C octadecane at a range of water, nutrient levels and freeze thaw cycles'. SUMMARY is the actual hydrocarbon concentrations in ug/g and weathering indices. GRAPHS-ABS are the graphs of absolute concentrations. GRAPHS-RATIO are the graphs of weathering indices. The fields in this dataset are: Days - Since experiment started. Hours - Since experiment started. Weight of NaOH (g) Count (dpm) - measurement from radiation counter - disintegrations per minute. Discarded dpm's - counts 'lost' from the system. Used in a 'mass balance'.
