Soil property, microbial abundance, and plant and invertebrate biomass data across a natural soil temperature gradient in Iceland from August 2018

This is a dataset of soil physiochemical properties, bacterial and fungal
abundance, and above and belowground plant and invertebrate biomass,
sampled at 40 plots in the Hengill geothermal valley, Iceland, from 15th
to 22nd August 2018. The plots span a temperature gradient of 10-35 °C
over the sampling period, and this temperature gradient is consistent over
time. The dataset also includes data on the decomposition rate of soil
organic matter, which was sampled at 60 plots in the Hengill valley from
May to July 2015.
