Abstract

This dataset contains leaf-level flux and soil porewater concentration measurements of carbon dioxide (CO2) and methane (CH4 ) in plots in the footprint of Ameriflux sites US-LA2 and US-LA3. Leaf fluxes in US-LA2 were measured on patches dominated by Sagittaria lancifolia and co-dominated by Sagittaria lancifolia and Typha latifolia. In US-LA3, fluxes were measured from distinct Juncus roemerianus and Spartina alterniflora patches. The porewater concentrations were collected across a vertical profile (~50 cm depth) at centric locations within 25 m2 plots where we measured the leaf fluxes. US-LA3 included an additional set of measurements in open water spots. We aimed to evaluate differences in leaf fluxes and porewater pools of CO2 and CH4 of representative ecohydrological patches across a salinity gradient. We also used this dataset to help develop ELM-Wet, a more realistic representation of wetland carbon biogeochemical processes within the U.S. Department of Energy’s Energy Exascale Earth System Model (E3SM) Land Model version 1 (ELM v.1). The files can be opened with regular text editors or spreadsheet programs. Version 2.0 (8/26/2025): This is the latest version of this dataset. The update includes additional samples of soil porewater CH4/CO2 concentrations from June-2021 to November-2022, as well as minor adjustments mademore »« less

Patch-level CO2 and CH4 fluxes and porewater concentrations in experimental wetlands, 2 PPT saltwater intrusion simulations, Aug-Oct 2022: Louisiana

Dataset Taj, Diana ; Villa, Jorge ; Bordelon, Robert

This dataset contains carbon dioxide (CO2) and methane (CH4) flux measurements from patches of wetland vegetation dominated by Typha domingensis and Panicum hemitomon, which were conducted to assess flux responses to acute saltwater intrusion. The measurements occurred before, during, and after simulated acute saltwater intrusion events of low concentrations of ~ 2 PPT. The measurements comprise gas fluxes from the wetland surface (i.e., soil-water column and vegetation) and fluxes from the soil-water column exclusively. These two sets of fluxes are separated into two files and are complemented with four more files containing porewater concentrations of CO2 and CH4 collected atmore »« less

Dataset Bohrer, Gil ; Ju, Yang ; Arend, Kristin ; ...

The data measurements of CH4 and CO2 at different patch types (classified by dominant macrophyte vegetation or hydrological state). CH4 and CO2 data include 3 types of measurements: 1) Surface flux measurements from chamber measurements. 2) Leaf flux measurements from plant chambers, providing the rate per leaf area of methane flow through three species of macropyte aerenchemous plants (Water Lily, American Lotus, and Cattail) with the corresponding flux of CO2 at the same leaves. 3) Pore water concentrations of dissolved CO2 and CH4 concentrations. These are measured along vertical profiles at varying depths from the soil-water interface using in-situ porewatermore »« less

In August-October 2012 and June-October 2013, co-located measurements were made of surface CH4 and CO2 flux, soil pore space concentrations and stable isotope compositions of CH4 and CO2, and subsurface temperature and soil moisture. Measurements were made in intensive study site 1 areas A, B, and C, and from the site 0 and AB transects, from high-centered, flat-centered, and low-centered polygons, from the center, edge, and trough of each polygon.

Soil Chamber Fluxes (CO2 and CH4) across a catena in the Luquillo Experimental Forest, Puerto Rico

Dataset Sihi, Debjani ; Salazar Ortiz, Mónica ; Mayes, Melanie

Wet tropical forest soils contribute significantly to global emissions of carbon dioxide (CO2) and methane (CH4). Landscape topography largely influences the rate of CO2 versus CH4 emissions from wet tropical forest soils. This dataset contains soil chamber fluxes of CO2 and CH4 from 2016 (April 5 through July 18) across a catena in the Luquillo Experimental Forest, Puerto Rico. Soil CO2 fluxes followed the trend of ridge>slope>valley. However, soil CH4 emissions followed the opposite trend, where valley soils served as the major source of CH4 emissions. This dataset can improve our understanding of greenhouse gas (CO2 and CH4) emissions associatedmore »« less
