Progress Code: completed Purpose In this study we use S. neumayeri to assess the risk from fuel spills to Antarctic nearshore marine ecosystems. We investigate the effects of the water accommodated fractions (WAFs) of three fuels: Special Antarctic Blend diesel (SAB), marine gas oil (MGO) and intermediate fuel oil (IFO 180), on fertilisation and normal embryonic and larval development of S. neumayeri. This dataset contains results of toxicity tests with early life stages of the sea urchin Sterechinus neumayeri as part of the AAS Project 3054 'Ecological risks from oil products used in Antarctica: characterising hydrocarbon behaviour and assessing toxicity on sensitive early life stages of Antarctic marine invertebrates.' Dataset consists of excel spreadsheets with separate spreadsheets for each test. Test details are outlined on worksheets 'Test conditions' and results of test in worksheet 'Counts'. This metadata record contains the results of toxicity tests conducted to characterise the response of Antarctic nearshore marine invertebrates to hydrocarbon contaminants in fuels commonly used in Antarctica as part of AAS Project 3054. This dataset contains results of toxicity tests conducted at Davis Station in 2010/11 summer season to test the sensitivity of fertilisation and early life stages of the sea urchin Sterechinus neumayeri to fuels in seawater. The three fuel types used were: Special Antarctic Blend diesel (SAB), Marine Gas Oil diesel (MGO) and an intermediate grade (180) of marine bunker Fuel Oil (IFO). Test treatments were obtained by experimentally mixing fuel and seawater in temperature controlled cabinets at -1 degrees C to prepare a mixture of fuel hydrocarbons in filtered seawater (FSW) termed the water accommodated fraction (WAF). WAF was produced by adding fuel to seawater in Pyrex glass bottles using a ratio of 1:25 fuel : FSW. This mixture was stirred at slow speed with minimal vortex for 18 h on a magnetic stirrer then settled for 6 h before the water portion was drawn from beneath the ...
