Details of MEPA Coastal Water Survey - Pollutants in Biota 2012


Dataset identification

Title of datasetMEPA Coastal Water Survey - Pollutants in Biota 2012
Narrative summary of datasetThe survey was conducted at 26 stations in the coastal waters of the Maltese Islands. The pollutant levels were measured during a pilot survey and then once (in two replicates) over the period between 30th May 2012 and 7th August 2012. During the surveys, samples of P. oceanica were collected from representative areas along the Maltese coast, and shipped to a laboratory in Italy for analysis according to the following procedures: UNI EN 15763:2010 (for Mercury); UNI EN 15662:2009 (for Hexachlorobenzene); EPA 5021A 2003 + EPA 8260C 2006 (for Hexachlorobutadiene). The measurements were made in connection with a monitoring survey of Maltese coastal waters. The resultant datasets generated provide the benchmark for long term monitoring programs and assessments that are required to implement EU Directives on water resources.
Summary of processing methodologyThe data was available in the form of a report in PDF format. This was digitized and validated using standard procedures. The metadata was then converted to an XML object and the data to ODV format.
