1991-04-12 — 1991-05-02

Status

Completed

Port of departure

Lowestoft, United Kingdom

Port of return

Lowestoft, United Kingdom

Objectives

1. To identify and quantify the fate of river-borne nutrients entering the Wash and Humber estuary, examining nutrient distributions and critical processes from the river inputs through to the North Sea in subtidal and intertidal sediments and the overlying water.
2. To measure factors affecting benthic nutrient cycling in subtidal sediments along a transect across the North Sea, in collaboration with the Netherlands Benthic Links and Sinks programme.
3. To recover the Tetrapod and current meter moorings from the north-east Irish Sea.
4. To deploy the Tetrapod at an anchor station next to STABLE in the north-east Irish Sea.
5. To conduct studies of Amphiura community related bioturbation in the north-east Irish Sea.
6. To conduct an anchor dredge survey of benthos at marine aggregate extraction sites near the Humber.
