BODC Cruise Metadata Report for RRS Challenger (74CH) cruise CH46

Introduction

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

Cruise Inventory Information

Long name RRS Challenger (74CH) cruise CH46
Short name CH46
Objectives and Narrative 1. To define the spatial and temporal characteristics of the plume of water originating in the Thames Estuary by repetetive sampling for selected conservative and non-conservative constituents around a grid enclosing the plume.
2. To determine the transport pathways for non-conservative constituents in relation to suspended particle/water exchanges through controlled experiments on board the research vessel.
3. To characterise the transfers of nutrient and metal species across the sediment/water interface by controlled on-board incubations of undisturbed sediment cores collected from within the survey area.
