attribute NC_GLOBAL acquisition_description String Time-series bottle samples were collected from the Sage Lot Pond salt marsh
tidal creek at approx. 41.5546N, 70.5071W. Samples were collected at ~0.2 m
below the surface of tidal creek water every 1-2 h at the sampling site using
a peristaltic or diaphragm pump for periods of a full tidal cycle (~12\u201314
h).Two coastal water samples were collected from the Woods Hole Oceanographic
Institution Environmental Systems Laboratory intake, located about 1.6 km
offshore in Vineyard Sound. Three goundwater samples were collected at the
edge of Sage Lot Pond salt marsh at the elevation of 0.42 m, 0.75 m, and 1.66
m (NAVD88), corresponding to 0.56 m, 0.89 m, and 1.8 m below the land surface,

The DIC, TA, and pH collection followed standard best practice procedures
outlined by Dickson et al. (2007). OrgAlk sample collection followed the TA
sampling protocol. Samples were collected through purgeable capsule filters
with 0.45 um pore size (Farrwest Environmental Supply, Texas, USA) into 250 mL
borosilicate bottles, poisoned with 100 uL saturated mercuric chloride, sealed
with a HDPE screw top or a glass stopper coated with APIEZON\u00ae \u2013 L
grease, and se- cured with a rubber band. Samples for DOC analysis were
filtered through 0.45 um pore size polyethersulfone cartridge filters into
combusted borosilicate glass vials with Teflon-lined silicone septa caps,
acidified to pH < 2 with hydrochloric acid and refrigerated until analysis.

DIC was analyzed using an Apollo SciTech DIC auto-analyzer (Model AS-C3),
which uses a nondispersive infrared (NDIR) method. The sample is acidified
with a 10% phosphoric acid in 10% sodium chloride solution, and CO\u2082 is
purged with high purity nitrogen gas and measured by a LI-COR 7000 infrared
analyzer (LI-COR Environmental, Nebraska, USA). Certified Reference Material
(CRM) from Dr. A. Dickson at Scripps Institution of Oceanography was used to
calibrate the DIC auto-analyzer at least once daily. In addition, CRM was
measured as a sample every few hours to gauge and correct any potential drift.
The precision and accuracy of the instrument was ~ \u00b1 2.0 \u03bcmol

TA was measured with a Ross combination pH electrode and a pH meter (ORION 3
Star) to perform a modified Gran titration (Wang and Cai, 2004). The electrode
and concentration of hydrochloric acid was calibrated every day. The CRMs were
also measured as samples every few hours to correct any potential small drift.
The accuracy and precision of the measurement was about 2.5\u00b11.9 \u03bcmol

The pH samples were measured with a UV-visible spectrophotometer (Agilent
8454, Agilent Technologies, USA) at 25 \u00b1 0.1\u2103 using purified meta-
cresol purple (mcp) as an indicator. The pH values are reported on the total
proton concentration scale and converted from 25 \u00b1 0.1\u2103 to in-situ
temperature using measured DIC and the CO2SYS program (van Heuven et al.,
2011). The mean uncertainty of the pH measurement was \u00b1 0.006 (range
0.0003 \u2012 0.017), calculated as the mean difference between duplicate

OrgAlk concentration was determined with a digital syringe pump, a Ross
combination pH electrode and a pH meter (ORION 3 Star), based on the procedure
reported in Cai et al. (1998). OrgAlk sample was titrated with a calibrated
HCl solution (~ 0.1 M) until the sample pH was below 3.0 (first titration).
CO\u2082 in the sample was then removed by bubbling with high purity N\u2082
gas (99.999%) for ~ 10 minutes. The acidified sample was then titrated with
0.1 M NaOH solution back to its initial pH (back titration). The NaOH solution
was prepared in DI water bubbled with high purity N\u2082 gas to prevent
CO\u2082 dissolution into the solution. Finally, the sample was titrated with
HCl again until its pH was below 3.0 (second titration). OrgAlk was calculated
as the TA from the second titration minus the borate alkalinity. The mean
difference of OrgAlk concentrations between duplicate samples was 2.8 \u00b1
2.1 \u00b5mol kg\u207b\u00b9. Due to the existence of a small amount of
CO\u2082 in the NaOH solution, the OrgAlk results were corrected by
subtracting introduced carbonate alkalinity based on the volume of NaOH
solution added during the back titration.

DOC samples were analyzed on an O. I. Analytical Aurora 1030C Autoanalyzer by
high-temperature catalytic oxidation followed by nondispersive infrared
detection (HTCO-NDIR). Concentrations are reported relative to a potassium
hydrogen phthalate (KHP) standard. Hansell deep seawater (University of Miami
Hansell Laboratory, Lot# 01-14), and Suwannee River NOM (IHSS, Lot# 2R101N)
reference materials were analyzed daily as additional checks on precision and
accuracy of the analyses. Standards and reference materials typically vary by
< 5%.

Tidal water samples for practical salinity were analyzed with a Guideline
AutoSal instrument at Woods Hole Oceanographic Institution. A YSI EXO2 Sonde
(YSI Inc., Ohio, USA) was submerged in the tidal creek to measure temperature
and water depth. Groundwater salinity and temperature were measured with a YSI
Pro30 (YSI Inc., Ohio, USA) during collection.The YSI EXO2 recorded at
intervals ranging from 2 min to 8 min. Reported YSI EXO2 sensor accuracy
specifications are: 1% of the reading for salinity and 0.05 \u00b0C for

attribute NC_GLOBAL instruments_0_description String The LI-7000 CO2/H2O Gas Analyzer is a high performance, dual cell, differential gas analyzer. It was designed to expand on the capabilities of the LI-6262 CO2/ H2O Gas Analyzer. A dichroic beam splitter at the end of the optical path provides radiation to two separate detectors, one filtered to detect radiation absorption of CO2 and the other to detect absorption by H2O. The two separate detectors measure infrared absorption by CO2 and H2O in the same gas stream. The LI-7000 CO2/ H2O Gas Analyzer is a differential analyzer, in which a known concentration (which can be zero) gas is put in the reference cell, and an unknown gas is put in the sample cell.

attribute NC_GLOBAL instruments_6_description String A Dissolved Inorganic Carbon (DIC) analyser, for use in aquatic carbon dioxide parameter analysis of coastal waters, sediment pore-waters, and time-series incubation samples. The analyser consists of a solid state infrared CO2 detector, a mass-flow controller, and a digital pump for transferring accurate amounts of reagent and sample. The analyser uses an electronic cooling system to keep the reactor temperature below 3 degrees Celsius, and a Nagion dry tube to reduce the water vapour and keep the analyser drift-free and maintenance-free for longer. The analyser can handle sample volumes from 0.1 - 1.5 millilitres, however the best results are obtained from sample volumes between 0.5 - 1 millilitres. It takes approximately 3 minutes per analysis, and measurement precision is plus or minus 2 micromoles per kilogram or higher for surface seawater. It is designed for both land based and shipboard laboratory use.

attribute NC_GLOBAL project String Salt Marsh Paradox
attribute NC_GLOBAL projects_0_acronym String Salt Marsh Paradox
attribute NC_GLOBAL projects_0_description String NSF Award Abstract:
Carbon production in vegetated coastal systems such as marshes is among the highest in the biosphere. Resolving carbon production from marshes and assessing their impacts on coastal carbon cycling are critical to determining the long-term impacts of global change such as ocean acidification and eutrophication. In this project, researchers will use new methods to improve the assessment of carbon production from salt marshes. The overarching goals are to understand the role of coastal wetlands in altering carbonate chemistry, alkalinity, and carbon budgets of the coastal ocean, as well as their capacity to buffer against anthropogenically driven chemical changes, such as ocean acidification. This project will involve training for undergraduate, graduate, and postdoctoral researchers, and will provide educational opportunities for students from a local Native American tribe.

Tidal water, after exchange with intertidal salt marshes, contains higher total alkalinity (TA), higher carbon dioxide, but lower pH. These highly productive, vegetated wetlands are deemed to export both alkalinity and dissolved inorganic carbon (DIC) to the ocean. This creates an apppartent paradox in that salt marshes are both an acidifying and alkalizing source to the ocean. Limited studies suggest that marsh DIC and alkalinity export fluxes may be a significant player in regional and global carbon budgets, but the current estimates are still far too uncertain to be conclusive. Unfortunately, tidal marsh ecosystems have dramatically diminished in the recent past, and are likely to diminish further due to sea level rise, land development, eutrophication, and other anthropogenic pressures. To assess the potential impacts of this future change, it is imperative to understand its current status and accurately evaluate its significatce to other parts of the carbon cycle. Similarly, little is know about the distinct sources of DIC and alkalinity being exported from marshes via tidal exchange, although aerobic and various anaerobic respiration processes have been indicated. In this study, researchers will undertake an in-depth study using new methods to vastly improve export fluxes from intertidal salt marshes through tidal exchange over minutes to annual scales, characterize and evaluate the compostiion (carbonate versus non-carbonate alkalinity) of marsh exported TA, the role and significance of the DOC pool in altering carbonate chemistry and export fluxes, identify sources of DIC being exported in tidal water, and investigate how marsh export of TA and DIC impacts carbonate chemistry and the carbon and alkalinity budgets in coastal waters.
