The dataset details surface sediment chlorophyll concentrations across six intertidal sites in the winter and summer of 2013. Chlorophyll concentrations in surface sediments (<2mm) provide a quantitative measure of the microphytobenthos (MPB) community present. Three of the sites were in Morecambe Bay, North West England and three of the sites were in Essex, South East England, each of these sites consisted of a saltmarsh area and adjacent mudflat area, twenty two sampling quadrats were placed on each area. Five replicate sediment samples were taken at each quadrat and then underwent acetone extraction of pigments followed by spectrophotometer analysis of absorptions at relevant wavelengths. Values for chlorophyll a, b and c1+ c2 are expressed as micrograms per gram of sediment. This data was collected as part of Coastal Biodiversity and Ecosystem Service Sustainability (CBESS): NE/J015644/1. The project was funded with support from the Biodiversity and Ecosystem Service Sustainability (BESS) programme. BESS is a six-year programme (2011-2017) funded by the UK Natural Environment Research Council (NERC) and the Biotechnology and Biological Sciences Research Council (BBSRC) as part of the UK's Living with Environmental Change (LWEC) programme.

The dataset details surface sediment colloidal carbohydrate concentrations across six intertidal sites in the winter and summer of 2013. Colloidal carbohydrate concentrations in surface sediments (top 2mm) provide a quantitative measure of the extracellular polymeric substances (EPS) secreted by organisms that form the microphytobenthos (MPB) community. Three of the sites were in Morecambe Bay, North West England and three of the sites were in Essex, South East England, each of these sites consisted of a saltmarsh area and adjacent mudflat area, twenty two sampling quadrats were placed on each area. Five replicate sediment samples were taken at each quadrat and were analysed using the Dubois Phenol-Sulphuric Assay which involves spectrophotometer analysis of absorptions to determine colloidal carbohydrate concentrations. Values for colloidal carbohydrate concentrations are expressed as glucose equivalents in micrograms per gram of sediment. This data was collected as part of Coastal Biodiversity and Ecosystem Service Sustainability (CBESS): NE/J015644/1.

The dataset details surface sediment water content across six intertidal sites in the winter and summer of 2013. Three of the sites were in Morecambe Bay, North West England and three of the sites were in Essex, South East England. Each of these sites consisted of a saltmarsh area and adjacent mudflat area, with twenty two sampling quadrats placed on each area. Five replicate sediment samples were taken at each quadrat and then freeze dried to give average percentage water content.

Triple-sulfur isotope data from schists and carbonates in the Eoarchean Isua Greenstone Belt (3.7 Ga), using a new leaching technique and a multi-collector ICP-MS. The results reveal distinct pattern between the two lithologies and demonstrate an atmospheric contribution of sulfur in both cases. This may support the notion that these rocks represent metamorphosed marine sediments. However, hydrothermal alteration needs to be assessed in more detail to verify the antiquity of these signatures.

The data represent a quantitative measure of aboveground (vegetation) biomass, organic carbon content and aboveground (vegetation) carbon from 144 vegetation samples collected across ten UK saltmarshes between 2019 and 2020. Sites were chosen to represent contrasting habitat types in the United Kingdom, in particular sediment types, vegetation, and sea level history.

The dataset comprises the surface stability of sediments as determined by a Cohesive Strength Meter (CSM). Between 3 and 5 replicate measurements were taken from each of the 22 designated experiment quadrats at each of the Coastal Biodiversity and Ecosystem Service Sustainability (CBESS) sites. At each CBESS site, a salt marsh site and a mud flat site was examined and three locations were selected in Morecambe Bay, North West England and three locations in Essex, South East England. The Morecambe Bay samples were taken during the winter and summer of 2013. The Essex samples were taken during the winter, early spring and summer of 2013. This data were collected as part of Coastal Biodiversity and Ecosystem Service Sustainability (CBESS): NE/J015644/1. The project was funded with support from the Biodiversity and Ecosystem Service Sustainability (BESS) programme.

The dataset includes measurements of dissolved and gaseous nitrogen oxides (nitrite, nitrate, NO(g)) generated by lightning discharge in a glass container partially filled with water, as well as measurements of dissolves sulfate and iron liberated from pyrite that has interacted with the nitrogen oxides. The lightning discharge experiments were carried out with either anoxic gas mixture (5% or 20% CO2 and the rest N2) or modern air. Lightning has long been identified as a source of reactive nitrogen species to Earth's early biosphere. These experiments were therefore conducted in order to test how this reactive nitrogen would interact with minerals at the Earth's surface. The results reveal that lightning-generated nitrogen oxides could have contributed to a small degree to oxidative weathering.

Nitrogen isotope and abundance data from brine seeps in the Gulf of Mexico. Three data tables show (1) Electrical Conductivity data for three sediment cores, (2) carbon and nitrogen data from all sediment cores investigated in this study, and (3) ammonium concentrations and isotopic data from brine pool samples. The results show high enrichments of ammonium in the brines, indicating that the brines actively mobilize bioavailable nitrogen back into the water column. Isotopic data reveal evidence of dissimilatory nitrate reduction to ammonium at the brine-seawater interface. Brine seeps have long been implicated in the formation of sediment-hosted hydrothermal ore deposits. Our results support the notion that brines may have stimulated biological productivity, facilitating trapping of metals in brine seep environments.

This dataset contains movement metrics of field crickets tracked within an arena modelled on a natural environment. Eight crickets were tracked per trial (13 trials in total), and each trial lasted 3 hours. Of the eight crickets, four were male and four were female. After the tracking ended, each female was allowed to lay eggs. The hatchlings were later counted, and this information is also included in the dataset.

This dataset comprises mathematically modelled data of soil-water saturation, along vertical profiles, at 6 sites near the Namoi River, south-eastern Australia. The vertical profiles span the soil surface down to 10m deep, divided into 944 intervals. The 6 sites are located at different distances from the Namoi River and are split between 2 locations (Old Mollee and Yarral East). The distances from the river channel at each location are, Old Mollee: 50m, 140m and 320m, and Yarral East: 40m, 110m and 290m. The dataset underpins figures presented in Evans et al. (2018). The data were modelled as part of a PhD project funded by the Natural Environment Research Council and the National Trust.
