Scanning Electron Microscopy - Energy Dispersive Spectroscopy data from surface seawater particles collected from the West Antarctic Peninsula during the Icebergs 3 JR19002 expedition
During the JR19002 Icebergs 3 cruise, particulate samples from the surface seawater were collected from Zodiacs. Samples were collected with the motivation of sampling glacially-derived particles and determining the biogeochemical composition and environmental significance of these particles with respect to iron and carbon cycling. Three main sites were visited during JR19002 from south to north: Marian Cove, Maxwell Bay, King George Island; Borgen Bay, Anvers Island; and Sheldon Cove, Ryder Bay, Adelaide Island. Small boat traversed each bay, collecting particulate and dissolved seawater samples. Scanning Electron Microscopy - Energy Dispersive Spectroscopy was performed upon three particulate samples at each site, to quantify the elemental composition of typical particles.

- Statement
- Quantification of element abundance was calibrated against the suite of SEM-EDS AZtec in-built standards, which necessitates all analyses being normalised to 100 percent, and elements of interest to have an atomic number more than 11, of which both conditions were met. The inbuilt AZtec EDS calibration setup requires routine calibration of the beam energy and the beam resolution, which was performed using a cobalt metal standard at 20 kV and a working distance of 15 mm.
