AUTOMATED MONITORING OF NI, CU AND ZN IN THE IRISH SEA

The distributions of Ni, Cu and Zn have been monitored in the Irish Se a using fully automated voltammetric instrumentation and collection of seawater by underway pumping. The continuous real-time measurements p rovided high resolution data with a minimum risk of sample contaminati on, The surveys showed that the River Mersey was a significant contrib utor of Ni, Cu and Zn to the eastern Irish Sea and that the trace meta l distribution was consistent with an anti-clockwise residual water mo vement in the eastern Irish Sea. The automated instrumentation is very useful for monitoring requirements for environmental impact assessmen ts and can provide high resolution trace metal data for marine modelli ng purposes.
