Status

Completed

Port of departure

Hull, United Kingdom

Barry, United Kingdom

Purpose

Research

Objectives

1. To quantify hydrodynamical transports and the processes affecting transformations, interactions and fates of particles, biogeochemically important elements and representative contaminants from land sources to the coastal zone.
2. To provide the first integrated environmental data base for a UK coastal region covering seasonal cycles and inter-annual variability and incorporating measurements of fluxes of materials and rates of biological productivity.
3. To generate a new quantitative understanding of estuarine and coastal zone processes controlling the fluxes and reactivities of both natural and anthropogenic materials.
4. To provide integratable models of these processes as building blocks for comprehensive coastal zone system models which will realistically predict the affects of future environmental change.
