Celtic Sea

Cruise Overview: [proposal abstract]
Low iron (Fe) concentrations control productivity, phytoplankton community structure and carbon cycling in 25 % of the open ocean. Iron concentrations are tightly coupled to Fe supply, and Fe fluxes from shelf seas to the open ocean are poorly constrained, although estimates indicate they could be 2-10 times higher than atmospheric inputs and thus potentially be a major contributor to the oceanic Fe cycle. The goal of this project is to quantify Fe fluxes from Celtic Sea to the adjacent North Atlantic Ocean. We will utilise trace metal clean sampling techniques, with associated physical diffusion and advection measurements, to determine the supply of dissolved, colloidal and particulate forms of Fe from sediments and their subsequent fate in shelf sea waters and during export to the North Atlantic Ocean. Radium isotopes will be used to determine the flux of iron from the shelf to the open ocean.
Inter-calibration efforts: Please provide details of how each element will be calibrated to meet the requirements of the GEOTRACES programme e.g. use of SaFe standards, collaborative sampling, cross-over stations (latitudes and longitudes of the cross over stations, the cruise which you are crossing with and the station numbers):
Replicate samples
List of parameters to be submitted to GDAC: Key parameters listed - please list any other parameters measured and the PI’s contact information associated with those parameters. Also include information in regards to the phase i.e. dissolved or particulate and how the samples were collected. i.e. Fe (dissolved)- CTD –Bottle or Fe (dissolved) – insitu pumps.
Could PI provide information on when samples are expected to be analysed so GDAC can estimate a data submission date
