Description

The DAERA Northern Ireland National Imposex Survey is a tri-annual (once every three years) assessment of the bioeffects of Tri-Butyl-Tin (TBT) on Nucella lapillus. Data is collected for the purposes of reporting to Water Framework Directive (WFD), the Marine Strategy Framework Directive (MSFD), the Clean Safe Seas Evidence Group (CSSEG), and the OSPAR Commission. Data consists of VDS (Vas Deferens Sequence) values for female specimens, and penis length measurements in millimetres of all specimens.
