Description
Data Records
The data in this occurrence resource has been published as a Darwin Core Archive (DwC-A), which is a standardized format for sharing biodiversity data as a set of one or more data tables. The core data table contains 249 records.
This IPT archives the data and thus serves as the data repository. The data and resource metadata are available for download in the downloads section. The versions table lists other versions of the resource that have been made publicly available and allows tracking changes made to the resource over time.

Geographic Coverage
Sea urchin individuals were collected in five sites separated by up to 5 km in the near-shore area surrounding Davis Station in the Vestfold Hills Region, East Antarctica.

Taxonomic Coverage
Main goal was to study and compare the fine-scale population structure and demographic history of three species of Antarctic sea urchins (Abatus ingens, Abatus shackletoni and Abatus philippii) in the near-shore area surrounding the Australian Reseach Sation Davis in East Antarctica. A secondary goal was to test potential impacts of pollution from the Davis Station wastewater discharge on the genetic diversity and effective population size of these species

Project Data
The present data set corresponds to the genotypes for seven microsatellite markers for three Antarctic sea urchin species of the genus Abatus. Sea urchin individuals were collected in five sites separated by up to 5 km in the near-shore area surrounding Davis Station in the Vestfold Hills Region, East Antarctica. For each microsatellite loci, the size of each allele was scored (in base pairs) using the CEQ 8000 Genetic Analysis System software v.8.0. Fragments were separated on an automated sequencer (CEQ 8000, Beckman Coulter) in the Central Science Laboratory at University of Tasmania.

| Design Description | Original datasheet was reformatted to fit GBIF/ IPT Biodiversity.AQ standard. The new datasheet "AbatusUrchin_microsatellites.csv" provides the dataset ID, verbatim latitude and verbatim longitude that were converted to decimal latitude and longitude, also provided. Taxonomical organisation to the lowest taxonomical rank that could be determined, after matched in WoRMS (World Register of Marine Species). Also provides other parameters such as localisation, sampling depth, occurrence, and date of event. |

Sampling Methods
Samples were collected from 5 sites, and the largest distance between any 2 sampling sites was 5 km. Three of the sites are considered heavily impacted: OF (outfall), OF1 and OF2 are within 500 m of the outfall pipe. The 2 control sites are considered to have negligible impact from the wastewater discharge; OF3 is located ~2.4 km from the outfall pipe to the northeast, and OF4 ~2.6 km to the southwest. Moreover, the OF3 and OF4 sites are both removed from the predominant longshore flow that transports the wastewater plume southeastwards along the coast (Stark et al. unpubli.). Samples from OF1 and OF2 were collected at 4.5− 7.0 m and 10−12 m depths, respectively, during the 2009/2010 Antarctic field season, and samples from OF, OF3 and OF4 were taken at depths <4 m during the 2012/2013 season.
| Study Extent | Individuals of 3 species of Abatus were collected in the near-shore area surrounding Davis Station (68°34’36’’S, 77°58’03’’E) located on Prydz Bay, Vestfold Hills, in Princess Elizabeth Land, East Antarctica. |
|---|---|
| Quality Control | Samples from sampling sites OF1 and OF2 were collected during the 2009/2010 summer season. Samples from sampling sites OF, OF3 and OF4 were collected during the 2012/2013 summer season. Depths at which samples were collected: OF1: 4.5-7.0 m deep OF2: 10-12 m deep OF, OF3, OF4 equal or less than 4 m deep. |
