The Dataset's Variables and Attributes

Row Type Variable Name Attribute Name Data Type Value
attribute NC_GLOBAL access_formats String .htmlTable,.csv,.json,.mat,.nc,.tsv
attribute NC_GLOBAL acquisition_description String The three ponds are located in the high marsh (1.43-1.46 m above North
American Vertical Datum of 1988) of the Plum Island Ecosystems \u2013 Long
Term Ecological Research (PIE-LTER) site. Surface sediments were collected
weekly for TOC, TN, \u03b413C, and \u03b415N (June 25-August 13 and November
11-25, 2014). Cores (5 cm diameter x 2 cm deep) were collected from three 1 m2
quadrats placed at random locations along two crisscrossing transects in each
pond. Sediments were combined in combusted glass vials to form composite
samples and stored (-80 \u2103) until analysis. sediment samples were prepared
for elemental and isotopic analyses by drying to constant mass (60 \u00b0C),
homogenizing with a Retsch Mixer Mill 200 (plants and sediments), and fuming
with hydrochloric (HCl) acid to remove carbonates (Hedges and Stern 1984).
Analyses were performed by the Stable Isotope Laboratory at the Marine
Biological Laboratory (Woods Hole, MA). Isotopic data are reported in the
conventional \u03b4-notation in units of per mil (\u2030).

attribute NC_GLOBAL instruments_1_description String Capable of being performed in numerous environments, push coring is just as it sounds. Push coring is simply pushing the core barrel (often an aluminum or polycarbonate tube) into the sediment by hand. A push core is useful in that it causes very little disturbance to the more delicate upper layers of a sub-aqueous sediment.

attribute NC_GLOBAL projects_0_description String Extracted from the NSF award abstract:
This project will address how rates of benthic microalgal production respond to eutrophication and geomorphological changes in human-impacted tidal creeks. Excess nutrient loading increases benthic algal biomass and likely stimulates production rates but the magnitude of nutrient and geomorphological effects on rates of production is unknown. Will changes in benthic algal productivity affect algal-bacterial coupling? Furthermore, how is algal-bacterial coupling affected by geomorphological changes, which may be exacerbated by excess nutrient loading but can also occur in pristine marshes?
This project will take advantage of the infrastructure of the TIDE project, a long-term saltmarsh eutrophication experiment at the Plum Island Ecosystem - Long Term Ecological Research site in Northeastern Massachusetts. Specifically, the PIs will measure benthic metabolism and examine algal- bacterial coupling in fertilized and ambient nutrient tidal creeks in the first field season. The following field season, they will compare sediment metabolism and carbon dynamics on slumped tidal creek walls (i.e. areas where low marsh has collapsed into the tidal creek) to that on the bottom of tidal creeks. In both years, gross and net production will be determined using an innovative triple oxygen isotope technique and traditional dissolved oxygen and inorganic carbon flux measurements. Comparisons between these methods will be useful in informing studies of sediment metabolism. Lipid biomarkers will be used to characterize the sources of organic matter to creek sediments, and stable isotope analysis of bacterial specific biomarkers to identify the sources of organic carbon utilized by sediment bacteria. The biomarkers will reveal whether sediment bacteria use organic matter substrates, such as benthic microalgal carbon, selectively or in proportion to availability. Overall, results from the proposed study will provide important information about how sediment carbon dynamics in shallow tidal creeks respond to long term eutrophication. Furthermore, findings will enhance understanding of the role of tidal creeks in coastal biogeochemistry.
