Parent Layer: Metal Contamination in Coastal Sediments

Name: Zinc Concentrations

Display Field: Conc_mgkg

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: Contours of total zinc concentrations produced from available data on coastal sediment quality in the Auckland and Waikato Regions.Waikato data were originally collected as part of an investigation into contaminant levels in the Southern Firth of Thames (see Kim, N. (2007) Trace elements in sediments of the lower eastern coast of the Firth of Thames. Environment Waikato Technical Report 2007/08, Environment Waikato, Hamilton) and in sediment samples collected as part of the Waikato RegionalCouncil's pollutants in sediments monitoring. Auckland data were collected as part of the Auckland Council's monitoring programmes (see Mills, G., Williamson, B. (2012) Marine sediment contaminants status and trends assessment 1998-2010. Technical Report, Auckland Council). The combined information is required by the Waikato Regional Council to support an assessment of aquaculture in the Hauraki Gulf.
