Progress Code: completed Statement: The concentrations were very low. Only for PCB153 several observations could be detected above detection limits. For other congeners most observations were below detection limits. Generally the samples of the Adelie penguins were smaller. 2018-08-29 - The original files was reformatted to fit OBIS/GBFI/IPT Biodiversity.AQ tracking standards, and a new datasheet "PollutantsInSeabirds_2003_04.csv" was created. The new dataset contains datasetID, occurrenceID, recordNumber, locationID, lifeStage, locality, verbatimLatitude, verbatimLongitude, decimalLatitude, decimalLongitude, eventDate, year, month, day, samplingProtocol, institutionCode, country, countryCode, measurementType, measurementUnit, measurementValue, dynamicProperties, occurrenceStatus, occurrenceRemarks, basisOfRecord, and associatedReferences. The lowest taxonomical rank of the species identified that could be determined is provided, after matched in WoRMS (World Register of Marine Species). Metadata record for data from ASAC Project 2357 See the link below for public details on this project. --- Public Summary from Project --- Contaminants like PCBs and DDE have hardly been used Antarctica. Hence, this is an excellent place to monitor global background levels of these organochlorines. In this project concentrations in penguins and petrels will be compared to 10 years ago, which will show time trends of global background contamination levels. Data set description From several birds from Hop Island, Rauer Islands near Davis, samples were collected from preenoil (oil that birds excrete to preen their feathers. This preenoil was then analysed for organochlorine pollutants like polychlorinated biphenyls, (PCBs), hexachlorobenzene (HCB), DDE and dieldrin. The species under investigation were the Adelie penguin (Pygoscelis adeliae) and the Southern Fulmar (Fulmarus glacialoides). The samples were collected from adult breeding birds, and stored in -20 degrees C as soon as possible. The analysis was done with relatively ...
