Progress Code: completed Statement: An technical failure occurred at the Australian Antarctic Division Marine Research Facility occurred in July 2013 in which organisms were exposed to temperatures up to 10oC for an exposed period of several days. Experiments using chemically and physically dispersed SAB were conducted in August and September 2013 using organisms that survived the increased temperatures. Organisms used in experiments may therefore be hardier than those occurring in the environment and results may suggest a higher tolerance to hydrocarbon exposure. Some contamination of hydrocarbon samples occurred during sampling, which test organisms were not exposed to. Contamination levels were therefore excluded from calculations of exposure concentrations. The hydrocarbon content of 0.1% dilutions was unable to be reliably analysed due to accuracy of the equipment and the interfering contamination. These values were extrapolated from analysis of 1% dilutions. It was determined that the extraction method was insufficient for the accurate quantitative recovery of hydrocarbons for the dispersant due to the presence of strongly polar molecules. As such, nominal concentrations were used for all dispersant only treatments and THC data represent the hydrocarbons from the fuel only for chemically dispersed treatments. This metadata record contains the results from bioassays conducted to show the response of the Antarctic gastropod, Skenella palludinoides to contamination from combinations of Special Antarctic Blend (SAB) diesel, chemically dispersed with fuel dispersant Ardrox 6120. Fuel only water accommodated fractions (WAF), chemically enhanced water accommodated fractions (CEWAF) and dispersant only treatments were prepared following the methods in Singer et al. (2000) with adaptations from Barron and Ka’aihue (2003). WAF was made using the ratio of 1: 25 (v/v), fuel to filtered seawater (FSW) following the methods of Brown et al. (2017). Ratios for chemically dispersed treatments were 1: 100 (v/v), fuel to ...
