String acquisition_description
"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. Leaves from S. alterniflora, S.
patens, R. maritima, and Ulva were collected in August 2014 from across the
marsh platform and all three ponds; tissues were combined in combusted (450
\\u2103) glass jars to form species-specific composite samples. Benthic
microalgae (BMA) were collected from ponds 1 and 2, as part of a separate
study (July 2016), by placing combusted glass slides on surface sediments for
one week and scraping attached material onto combusted glass fiber filters.
All samples were frozen (-20 \\u2103) until analysis for TOC, TN, \\u03b413C,
and \\u03b415N. Samples were prepared for elemental and isotopic analyses by
drying to constant mass (60 \\u00b0C) 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).";

"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.";

Data Access Protocol (DAP) and its
selection constraints.
The URL specifies what you want: the dataset, a description of the graph or the subset of the data, and the file type for the response.
Tabledap request URLs must be in the form
https://coastwatch.pfeg.noaa.gov/erddap/tabledap/datasetID.fileType{?query}
For example,
https://coastwatch.pfeg.noaa.gov/erddap/tabledap/pmelTaoDySst.htmlTable?longitude,latitude,time,station,wmo_platform_code,T_25&time>=2015-05-23T12:00:00Z&time<=2015-05-31T12:00:00Z
Thus, the query is often a comma-separated list of desired variable names,
followed by a collection of
constraints (e.g., variable<value),
each preceded by '&' (which is interpreted as "AND").
For details, see the tabledap Documentation.
