The data show the efficiency of phosphate and phosphite adsorption onto ferrihydrite precipitates that were generated in artificial seawater solutions in the laboratory. The experiments were carried out at pH 7 and pH 8. Solution compositions are provided along with the P data.

The data include measurements of adsorption experiments, where the adsorption fraction of phosphite and phosphate on experimentally-prepared ferric iron oxides were measured. The amounts of phosphate and phosphate as well as iron retained in solution were measured to calculate the fractions adsorbed relative to iron precipitated. In addition, total phorphorus and iron concentrations as well as phosphite and phosphate concentrations in leachates of natural banded iron formation samples from the Neoarchean to Paleoproterozoic. For the BIF samples, also XRD data are presented.

This data set contains the ULF wave model output data required to produce the figures in the article: A. W. Degeling, I. J. Rae, C. E. J. Watt, Q. Q. Shi, R. Rankin and Q. G. Zong, "Control of ULF Wave Accessibility to the Inner Magnetosphere by the Convection of Plasma Density", J. Geophys. Res. (accepted Dec. 2017) doi:10.1002/2017JA024874 The dataset has a Matlab binary file format. It consists of a structure array "d" (with 325 elements). These elements correspond to the 2D parameter scan in driver frequency and elapsed time during plume development performed for this study. The elapsed time parameter has 25 elements, ranging 0 to 24 hours (i.e. 1 hour spacing), and the driver frequency parameter has 13 elements ranging from 1 to 7 mHz (with 0.5 mHz spacing). e.g. use "d = reshape(d,25,13);" to reshape the structure array into 2D with columns for the frequency scan and rows for the elapsed time scan. The Matlab function "make_PDP_figs.m" is used to read the data, perform the necessary post-processing operations and output the article figures. To produce all six figures, simply run the file without any input arguments.

This dataset comprises of geochemical, mineralogical and microbiological analyses of material collected on the southwestern margin of the Greenland Ice Sheet in 2016 and 2017. Stream water, melted ice and snow samples were collected and analysed for carbon, nitrogen, phosphorus, cation and anion concentrations, pH, conductivity, total dissolved solids (TDS), mineral phase and class abundances and Rare Earth Elements (REE). Microbial community composition was also analysed. In addition, the results of a nutrient incubation experiment are also presented.The data were collected as part of a project investigating drivers of glacial ice algal growth on the Greenland Ice Sheet.
