Status | Completed |
Port of departure | Belfast, United Kingdom |
Port of return | Belfast, United Kingdom |
Purpose | Research |
Objectives | 1. 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. 3. To quantify copepod egg production in relation to food (phytoplankton availability and quality. 4. To service the DARD mooring. |

Measurements | |
Physical oceanography | |
Subsurface temperature and salinity measurements | Description: Near surface temperature and salinity were recorded along three transect lines. |
Chemical oceanography | |
Oxygen | Quantity: 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 | |
Zooplankton | Quantity: number of samples = 1 Description: DARD mooring was serviced, water column sampling and zooplankton collection took place. |
Eggs and larvae | Quantity: number of samples = 1 Description: Copepod samples were collected, using a 200µm mesh ring net, for egg production experiments. No. of samples not specified. |
Crustaceans | Quantity: number of samples = 1 Description: Copepod samples were collected, using a 200µm mesh ring net, for egg production experiments. No. of samples not specified. |
Geology and geophysics | |
Core - soft bottom | Quantity: 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. |
