PurposeResearch
Objectives1. To investigate the coupling between primary production and benthic mineralisation rates in the vicinity of the Isle of Man-Dublin tidal mixing front.
2. To undertake measurements of primary production and chlorophyll biomass for comparison with satellite derived estimates.

Measurements 
Physical oceanography 
Subsurface temperature and salinity measurementsDescription: Near surface temperature and salinity were recorded along three transect lines.
Chemical oceanography 
OxygenQuantity: number of samples = 1
Description: Sediment samples were collected using a box corer. They were used to estimate rates of oxygen uptake, sulphate reduction and nutrient efflux. Extra samples were taken to look at organic carbon and pigment content. No. of samples taken not specified.
Biology and fisheries 
ZooplanktonQuantity: number of samples = 1
Description: DARD mooring was serviced, water column sampling and zooplankton collection took place.
Eggs and larvaeQuantity: number of samples = 1
Description: Copepod samples were collected, using a 200µm mesh ring net, for egg production experiments. No. of samples not specified.
CrustaceansQuantity: number of samples = 1
Description: Copepod samples were collected, using a 200µm mesh ring net, for egg production experiments. No. of samples not specified.
