The data comprises both compositional data and growth assay data from an experiment of wild bacterial communities in Wytham Woods, Oxford. The communities live in puddles of water in tree-holes formed by the roots of beech trees. We manipulated the pH of tree-holes during the experiment for comparison with control tree-holes that were unmanipulated. Compositional data comprises the frequency of different Amplicon Sequencing Variants and derived measures of species diversity for samples taken over time (up to 12 weeks from the start of the experiment). The growth assay data comprises measurements of growth rates of community samples and isolates back in the laboratory, when grown on beech tea media manipulated to have different pHs.

During the JR19002 Icebergs 3 cruise, samples from the surface seawater were collected from Zodiacs. Samples were collected with the motivation of determining the impact of retreating glaciers upon the surface ocean, such as the hydrography and biogeochemical composition of the surface ocean. 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. Parameters collected and determined include: stable oxygen isotopes, salinity, dissolved macronutrients, dissolved and particulate metals, radium and thorium activity. Funding: NERC grants, NE/P017630/1 (Dr Amber Annett) and NE/P003060/1 (Professor David Barnes).

This dataset is a recording of passive seismic responses on Eastwind Glacier (Windless Bight, Ross Island, Antarctica), also containing 212 active-source seismic shots made with a hammer and plate source. The data are recorded using fibre optic distributed acoustic sensing (DAS), with a 2.2 km cable length connected into a FEBUS Optics A1 interrogator. The acquisitions take place over a two-hour period from 23:46 UTC on 2024-02-06, to 01:54 UTC on 2024-02-07. The acquisition is part of a broader campaign of seismic measurements to determine grounding line dynamics of Eastwind Glacier and image the bathymetry of the sub-shelf ocean cavity. The data were recorded as part of the ITGC TIME and EGGS ON TOAST projects, by a team from various UK and US institutions. The data are presented as HDF5 files. with supporting information provided in CSV files.
