Tropical Peatland Drainage Canal Methane Concentrations, Fluxes, and Isotopic Composition

This dataset contains methane (CH₄) concentration and ¹³C isotope composition (δ¹³C-CH₄) and environmental variables (canal dimensions, water quality, etc.) from canals draining peatlands in West Kalimantan, Indonesia. The data also contains CH₄ emissions measured using floating chambers and potential CH₄ oxidation rates and associated isotopic fractionation from a subset of studied canals, as well as porewater data from peat soils in the study region. Each data file contains a "README" tab with a guide for variable units and descriptions. 

File contents: 

• Canal_CH4_Survey_Perryman.xlsx = canal water CH₄ concentration and δ¹³C-CH₄ from a synpotic survey of canals in Kubu Raya Regency and Mempawah Regency, West Kalimantan, Indonesia. Data also includes canal properties, water chemistry, and estimates of the fraction of CH4 oxidized and diffusive emissions for each canal
• Canal_Water_Incubations_Perryman.xlsx = measurements of dissolved CH₄ concentration and δ¹³C-CH₄ from canal water incubations
• Floating_Chamber_Flux_Perryman.xlsx = CH₄ emissions and source δ¹³C-CH₄ determined from floating chamber deployments on canals
• Porewater_CH4_Perryman.xlsx = peatland  porewater CH₄ concentration and δ¹³C-CH₄ from 6 profiles collected in the study area
