1. To continue the examination of the distribution of strontium-90, caesium-I34, caesium-137, plutonium-238, plutonium-239/240 and americium-241 in sea water.
2. To determine the suspended load and particle size distribution in sea water and to measure the chlorophyll-a content at selected stations.
3. To continue the work on determination of the oxidation states of plutonium in sea water, sediments and interstitial waters.
4. To complete work on the shipboard concentration technique for the determination of total plutonium in sea water.
5. To measure concentrations of polonium-210, strontium-90 and radium-226 in seawater using a shipboard concentration technique and to collect a few plankton samples for subsequent analysis for polonium-210.

North-west of British Isles and North Sea.

Sampling grid: radionuclides, suspended load and salinity, chlorophyll a, seawater, suspended particulate material and radionuclides in water. Water processed for radio caesium, plutonium, americium, strontium-90, radium-226 and polonium-210, Pu+4/Pu+6. Also, coring attempted at 6 stations
