Stable oxygen and hydrogen isotope composition of precipitation, river water and lake water in the Five Lakes of Mikata catchment, 2011-2012 and 2020-2022
This dataset contains information about the stable oxygen and hydrogen isotope composition (δ18O, δ2H and d-excess) of waters within the Five Lakes of Mikata catchment. Datapoints span March 2011 – January 2012 and July 2020 – July 2022. Samples include precipitation on an event-basis, weekly river water and weekly lake water. To accompany the precipitation isotope composition data, total precipitation and average temperature during each subsampling period is provided. Water temperature and salinity variations with depth within Lake Suigetsu on six dates across the 2020 – 2022 sampling interval are also given. This data was collected to determine if catchment water composition reflects East Asian Monsoon variability.

Provenance & quality
River and lake water samples were taken using a collection vessel for surface samples or a sealable van Dorn water sampler for deep samples. Precipitation samples were taken using a purpose-built funnel and glass bottle holder. Water samples were then transported to the British Geological Survey, UK, for analysis on an Isoprime 100 mass spectrometer with an Aquaprep dual-inlet system (to yield δ18O values (‰)) and continuous flow, high temperature conversion elemental analyser - IRMS (EuropyrOH-Isoprime) with liquid autosampler (to yield δ2H values (‰)). D-excess values (in ‰) were calculated from these quantities. Water temperature (°C) and salinity data (%) were collected using a Hydrolab DS5 water quality meter and TOA-DKK WQC-24 meter. Total precipitation (mm) and average temperature (°C) were monitored using a Netatmo weather station.
