PurposeResearch
Objectives1. To map the surface distribution of temperature and salinity in the westrn Irish Sea.
2. To investigate water column structure and the vertical distribution of dissolved inorganic nutrients and microplankton biomass at the DARD fixed sampling stations in the Irish Sea.
3.To collect samples of suspended particulate material for estimation of particulate organic carbon and nitrogen, bulk biochemical constituents (protein, carbohydrate and lipid) and microplankton species composition and abundance.
4.To collect zooplankton samples from the DARD fixed sampling stations.

CTD stationsQuantity: number of observations = 5
Description: A transect of 5 CTD stations across the Irish Sea was worked.
CTD stationsQuantity: number of samples = 1
Description: At the DARD fixed station a CTD profile was recorded and water samples were collected for the determination of dissolved nutrients and chlorophyll. No. of samples not specified.
Subsurface temperature and salinity measurementsQuantity: number of samples = 1
Description: At the DARD offshore mooring the vertical profile for temperature and salinity was recorded. Water samples were collected for the determination of dissolved nutrients, estimation of phytoplankton chlorophyll and characterisation of the seston. No. of samples not specified.
