Dissolved trace metals (dAl and dPb) for UK Shelf Sea Biogeochemistry.

This dataset contains measurements from CTD rosette bottles of seawater dissolved trace metals lead (dPb) and aluminium (dAl) from the Celtic Sea (50N, 8W). The samples were collected during RRS Discovery cruises DY018, DY029 and DY033 between November 2014 - August 2015, as part of the UK Shelf Sea Biogeochemistry research programme (UK-SSB). Seawater samples were collected and handled using ultraclean procedures (e.g. Cutter et al. 2010). DPb was analysed in pH buffered (ammonium acetate), pre-concentrated samples by HR-ICP-MS using an Element XR (Thermo Scientific). DAl was measured following the formation of an aluminium spectrofluorometric complex (lumogallion) and analysed by a spectrofluorometer (The Cary Eclipse Fluorometer). The data were collected as part of the SSB research programme in the Biogeochemistry of Trace Metals in Shelf Seas research programme component. SSB was co-funded by the Natural Environment Research Council (NERC) and the Department for Environment, Food and Rural Affairs (Defra). The programme took a holistic approach to the cycling of nutrients and carbon and the controls on primary and secondary production in UK and European shelf seas, to increase understanding of these processes and their role in wider biogeochemical cycles. The British Oceanographic Data Centre (BODC) created the metadata entry and is responsible for holding master copies of the data.
