PurposeResearch
ObjectivesThis was the second of a three-cruise programme. The cruises were aimed at determining the concentrations of biogeochemically active metals which are potentially pollutants in coastal waters. The three cruises will make possible an assessment of how metal concentrations vary in relation to the biological and other processes which create the well-documented annual cycle in nutrient element concentrations in coastal waters. Three areas of work were conducted on this cruise:
1. Collection and shipboard analysis of samples to determine the hydrography of the water being sampled - temperature, salinity and micronutrients.
2. Collection of samples for trace metal and metalloid analysis by established methods.
3. Development of electrochemical methods for the continuous determination of metals on board ship.
