This data record has been compiled for a statistical methods study, conducted by Abigael Proctor as part of her PhD research in 2018. The data in this record have been used to showcase a new statistical method for determining no effect concentration (NEC). The study uses the data in this record to compare NEC and LCx estimates for copper in four Antarctic marine invertebrate species. The data associated with this record are a subset of four existing larger datasets: 1. amphipod: AAS_2933_Orchomenella_pinguides_Sensitivity_metals_Davis_2010-11 2. copepod: AAS_4100_Toxicity_Copepods 3. gastropod: AAS_2933_MetaToxicityMarine_JuvenileGastropods_Kingston2007 4. ostracod: AAS_2933_MetalToxicityMarine_BrownOstracods_Kingston2007 Subset details are described in the excel file provided.

This data set describes the toxicity of marine sediment spiked with undispersed diesel and diesel dispersed with Dasic Slickgone to the Antarctic ophiuroid Ophiura crassa. In 4 experiment ophiuroids were exposed for 10 days with daily observations of the movement of the animals as an indication of health. This work falls under the umbrella project ASAC_2201. The fields in this dataset are: Concentration SAB Time Animals Moving

These data sets describe the toxicity of lead, coppyer, zinc and cadmium spiked seawater to the juveniles of Abatus ingens and Abatus nimrodi. Metals were tested separately over exposure periods of 96 and 240 hours. The experimental endpoint was mortality as defined by cessation of observable movement. The coding system for the data files is J(juvenile)_An (Abatus nimrodi) or Ai (Abatus ingens) - Metal name_Dates of the experiment_ the period of the observation (96 hour or 240 hour). This work falls under the umbrella project ASAC_2201. The fields in this dataset are: Species Toxicant Date Replicate Concentration Moving pH Salinity Dissolved Oxygen

This data set describes the toxicity of marine sediment spiked with undispersed diesel and diesel dispersed with Dasic Slickgone. The temperate heart urchin species Echinocardium cordatum was exposed for 10 days to each contaminant with daily observations of the degree of burial of the animals. The data for this project was collected as part of the umbrella project ASAC_2201. The fields for this dataset are: Date Time Urchin Buried Alive Salinity Dissolved Oxygen pH Temperature

This data set describes the toxicity of marine sediment spiked with contaminated soil from Thala Valley tip site at Casey. The temperate heart urchin species Echinocardium cordatum was exposed for up to 10 days with daily observations of the degree of burial of the animals. The data for this project was collected as part of the umbrella project ASAC_2201. The fields for this dataset are: Date Time Urchin Buried Alive Salinity Dissolved Oxygen pH Temperature
