Objectives1. To collect biological (phytoplankton and zooplankton), chemical (dissolved
inorganic nutrients and particulate carbon and nitrogen) and physical (sea
temperature, conductivity and surface and sub-surface irradiance) data from
selected stations in the Irish Sea for the purpose of continuing the
observational study of the biological oceanography of the NW Irish Sea.

2. To undertake experiments to estimate the rate of carbon fixation by
phytoplankton at selected stations using a simulated in situ incubation

3. To collect sediment cores from selected stations for the purpose of estimating
the amounts of phytoplankton pigments in the sediment and the organic carbon
and nitrogen content of the sediment.

4. To collect samples of benthic macrofauna using the day grab.

Work at station 38 was abandoned because sea conditions were considered too rough to safely deploy scientific equipment.
