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
