PIE LTER transects of the Parker River Plum Island Sound Estuary, Massachusetts conducted at dawn and dusk, containing dissolved oxygen, conductivity, temperature, percent saturation, pH, DIC and pCO2 data.
Multi-year transects, beginning in 1995, of the Parker River Plum Island Sound Estuary conducted at dawn and dusk, containing dissolved oxygen, conductivity, temperature, percent saturation, pH, salinity, DIC and pCO2 measurements. Differences between dawn and dusk measurements can be used to determine the water metabolism and corresponding estimates of gross primary production, total system respiration and net ecosystem production.
Transects of the Rowley River, Plum Island Sound Estuary, Massachusetts conducted at dawn and dusk, containing dissolved oxygen, conductivity, temperature, percent saturation, pH, DIC and pCO2 data, PIE LTER.
Multi-year transects, beginning in 2016, of the Rowley River Plum Island Sound Estuary, MA conducted at dawn and dusk, containing dissolved oxygen, conductivity, temperature, percent saturation, pH, DIC and pCO2 measurements. Differences between dawn and dusk measurements can be used to determine the water column metabolism and corresponding estimates of gross primary production, total system respiration and net ecosystem production.
DIC and DOC 13C tracer data from Shark River Slough and Harney River (FCE), Everglades, South Florida in November 2011
As part of the larger NSF WSC funded project, an SF6 tracer study was conducted in November of 2011 by working groups form ENP, FIU and Univ. of Hawaii. This work included the release of the tracer (SF6), which was sampled in a lagrangian approach as the tracer “patch” moved from the fresh water portion of the system to the mangrove ecotone along the Shark and Harney Rivers. The goal of this study was to measure carbon export through the system. Annie Palya used our new CRDS system to measure the isotopic composition (d13C) of the DOM & DIC (analyzed at RSMAS) during this study, as carbon isotopes may help to resolve different sources of carbon. This analytical approach is relatively new, and will be important for understanding the C-dynamics within the FCE.
Survey of dissolved inorganic carbon (DIC) and dissolved oxygen (DO) along the Duplin River in 2014
A transect measure of inorganic carbon and oxygen level at 12 equidistant stations along the Duplin Rvier were conducted at sunrise, sunset and next sunrise for each season in 2014 in order to estimate the air-water exchange, longitudinal mixing and metabolism of the Duplin River ecosystem.
Anchor sampling of inorganic carbon (DIC) and dissolved oxygen (DO) at the flux tower tidal creek in the Duplin River
An anchor sampling of DIC and DO level at the mouth of a first order creek of the Duplin was conducted seasonally in order to estimate the metabolism and CO2/O2 dynamics of water when it floods the marsh where the GCE LTER project operates an eddy covariance tower.

Accession numbers for radiocarbon and stable carbon isotopes of dissolved organic carbon (DOC) and dissolved inorganic carbon (DIC) in soil leachates from permafrost soils collected from the North Slope of Alaska in the summers of 2018 and 2022
Leachates of dissolved organic carbon (DOC) from permafrost soils were prepared from soils collected from the North Slope of Alaska in 2018 and 2022. Soil leachates were then either kept in the dark or exposed to light from LEDs at 305 nm (UV) and 405 nm (visible), and then inoculated with native microbial communities and incubated. At the start of the biological incubations, single replicates of the DOC after dark or light treatment and inoculation were assigned accession numbers and analyzed for 14C and 13C at the National Ocean Sciences Accelerator Mass Spectrometry (NOSAMS) facility. At the end of the biological incubations, duplicates of the dissolved inorganic carbon (DIC) in those waters were assigned accession numbers and analyzed for 14C and 13C at the NOSAMS facility.

Stable and radiocarbon isotope compositions of DOC and DIC in Southeast Asian drainage canals
<p>This dataset contains the stable and radiocarbon isotope compositions of dissolved organic carbon (DOC) and radiocarbon isotope compositions of dissolved inorganic carbon (DIC) produced during DOC microbial respiration and photomineralization in canal waters sampled across disturbed peatlands in West Kalimantan, Indonesia in 2022. Microbial respiration and photomineralization experiments were carried out during laboratory incubations and natural sunlight exposures of canal water samples, respectively. Significant changes in the radiocarbon isotope composition of DIC between treatment and control waters were detected using a headspace extraction technique followed by a small-carbon extraction line for radiocarbon samples. </p>
