Details of MEPA Coastal Water Survey - Physicochemical 2012/13


Dataset identification

Title of datasetMEPA Coastal Water Survey - Physicochemical 2012/13
Narrative summary of datasetThe survey was conducted at 26 stations in the coastal waters of the Maltese Islands. Physicochemical parameters were measured at monthly intervals over the period between 30th May 2012 and 24th July 2013. Measurements were made only at a depth of 5m from the surface. All parameters were measured using a multi-parametric probe. The multiparametric probe used was the YSI 6820 V2-1, equipped with a data display and logging system YSI 650 MDS. This probe has one optical port, conductivity/temperature port, Rapid Pulse DO port, pH/ORP port, and 3 ISE ports.
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.
