BODC Cruise Metadata Report for RRS Challenger (74CH) cruise CH115B

Introduction

This report collates information from the BODC cruise inventory and oceanographic databases. It presents

Cruise Inventory Information

Long name RRS Challenger (74CH) cruise CH115B
Short name CH115B
Objectives and Narrative 1. To quantify the 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 interannual variability and incorporating measurements of the fluxes of materials and rates of biological productivity.
3. To generate 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 effects of future environmental change.
