Ship name (ship code)

RRS Challenger (74CH)

Cruise identifier

CH46

Cruise period

1989-02-12 — 1989-02-20

Status

Completed

Port of departure

Great Yarmouth, United Kingdom

Port of return

Great Yarmouth, United Kingdom

Purpose

Research

Objectives

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.
