| Cruise identifier | CIR5/90 | ||||
| Cruise period | 1990-05-03 — 1990-05-20 | ||||
| Status | Completed | ||||

| 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 intertidal and subtidal sediments and the overlying water column.
2. To measure Ra-226 concentrations in filtered water as an indicator of potential anthropogenic sources of naturally-occurring radionuclides, prior to making use of such nuclides to quantify sediment processes. 3. To collect water samples in the S North Sea to examine the distribution of Sb-125, from the Cap de la Hague reprocessing plant. | ||||
