Purpose

Research

Objectives

1. To define the spatial and temporal characteristics of the plume of water originating from the Humber Estuary and the Wash 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 cores collected from within the survey area.
