Brief description

This dataset contains the results of experiments that measured the total hydrocarbon content (THC) in water accommodated fractions (WAF) of fuel in seawater. The three fuel types were: Special Antarctic Blend diesel (SAB), Marine Gas Oil diesel (MGO) and an intermediate grade (180) of marine bunker Fuel Oil (IFO).

These tests were performed under conditions which conformed to protocols used in Project 3054 toxicity tests conducted on Antarctic and subantarctic marine invertebrates.
These hydrocarbon data show measured concentrations of THC in WAFs over time. From these data exposure concentrations of THC can be derived for analysis of sensitivities of marine invertebrates exposed to these WAFs in bioassays of Antarctic and subantarctic marine invertebrates. The integrated exposure concentrations calculated from these data are held in datasets AAS_3054_THC_WAF_integ_ conc_ 09_10 and AAS_3054_THC_WAF_integ_ conc_10_11_12.

Fuels were experimentally mixed by slow stir of fuel and seawater in temperature controlled cabinets at 0 degrees C and 5 degrees C to prepare a mixture of fuel hydrocarbons in filtered seawater (FSW). WAF was produced by adding fuel to seawater in 10 L glass bottles. Mixtures were stirred at slow speed with minimal vortex. The freshly decanted WAFs were sampled and an additional set of time series experiments sampled the THC in dilutions of decanted WAFs in open containers, to show the loss of hydrocarbons over time at 0 degrees C and 5 degrees C. WAF samples were extracted and THC in micrograms per litre was measured using gas-chromatograph flame ionising detection (GC_FID) analysis.

The dataset consists of an Excel spreadsheet. The first worksheet 'Test description' gives details of test setup and conditions, and explanation of acronyms. The following worksheets show the THC in test samples, with a separate worksheet for each test. Two worksheets 'Raw data' show the data from GC_FID analysis.

Notes

Purpose
These data are used in determining exposure concentrations in toxicity tests of Antarctic and subantarctic marine invertebrates to assess ecological risks associated with fuel use in Antarctic waters.
