Manual snow density (km m-3) from a 1-m deep snow profile from southwest Greenland (Camp Raven, 66.48 N, 46.30 W, 2331 m asl) during Summer 2024. The snow profile measurements were made adjacent to an autonomous atmospheric and glaciological platform (the SLEIGH) as part of the ICECAPS-MELT (Integrated Characterization of Energy, Clouds, Atmospheric state, and Precipitation - MEasurements along Lagrangian Transects) experiment. Manual snow density was measured using American Avalanche Association classifications and procedures (Snow, Weather, and Avalanche Guidelines, 4th Edition, 2022). This profile was made 2-3 m away from the SLEIGH. This work was US-led, US-UK collaboration co-funded by the US National Science Foundation and the UK National Environment Research Council.

We present a petrophysical catalogue of new density and susceptibility measurements conducted on 320 rock samples from northern Victoria Land, East Antarctica. The rock samples are stored by the Federal Institute for Geosciences and Natural Resources (BGR) in Berlin-Spandau and Hanover, Germany. Funding for this research was provided by NERC through a SENSE CDT studentship (NE/T00939X/1)

The dataset contains measurements of the annual average abundance, biomass and elemental composition (C, N, P) of consumers (fish and invertebrates) in six rivers within sub-catchments of the Hampshire Avon of contrasting geology (clay, sand, chalk).

This dataset contains detailed records of snowpack characteristics near Ny-Alesund, Svalbard, between 21st and 31st March 2023. They were recorded in ten snow pits before in-situ tracer percolation experiments, and the records include location and overview photos of each pit, snow height, snow temperature, snow density, detailed snow stratigraphy observations, and stable water isotope signatures from the snow surface to the ground. The records were obtained by Dorothea Moser as part of an experimental field project ("Wet Fingerprints") to contextualise the results of the subsequently conducted tracer percolation experiments. The project was supported by an Arctic Field Grant through the Norwegian Research Council (Project No. 342165, Research in Svalbard RiS ID 12132). Dorothea Elisabeth Moser was supported by BAS Cambridge and the NERC C-CLEAR Doctoral Training Programme (grant no. NE/S007164/1).
