String acquisition_description
"Seawater was transferred to 20 L carboys that were rinsed three times with
water from the sampling depth. Experiments on (operationally defined)
particles were carried out by gravity-filtering water through 3 um pore size
filters.\\u00a0Fractions of the filters (1/8 of each filter) was incubated in
autoclaved seawater from the same depth/station; bacterial protein production
was calculated to account for the volume of seawater that had passed through
the filter.
Bacterial protein production was measured from 3H-leucine incorporation by
heterotrophic bacteria using the cold trichloroacetic acid (TCA) and
microcentrifuge extraction method [as in Kirchman, 2001]. All work was
performed aboard ship. In brief, triplicate live samples of 1.5 mL seawater as
well as one 100% (w/v) TCA-killed control were incubated with 23 uL of
L-[3,4,5-3H(N)]-Leucine (PerkinElmer, NET460250UC) for between 4 and 24 hours
in the dark at as close to in situ temperature as possible. Live samples were
then killed with 89 uL of 100% (w/v) TCA and centrifuged (10,000 rpm at
4\\u00b0C for 10 min) to pelletize cell material.\\u00a0 The supernatant liquid
was removed and 1 mL of 5% (w/v) TCA solution was added, followed by vortex
mixing and centrifugation. Supernatant removal, mixing, and centrifugation
were repeated using 1 mL of 80% ethanol solution.\\u00a0 Finally, the
supernatant liquid was removed and each sample was dried overnight.\\u00a0
After drying, 1 mL of scintillation cocktail (ScintiSafe 30% Cocktail, Fisher
SX23-5) was added and incorporated radioactivity was measured using an LSA
scintillation counter (PerkinElmer Tri-Carb 2910TR). Leucine incorporation
rate was calculated from the incorporated radioactivity, compared to 1 mL of
scintillation cocktail spiked with 23 uL of L-[3,4,5-3H(N)]-Leucine
radioactivity, divided by incubation time.";

"NSF Award Abstract:
Heterotrophic microbial communities are key players in the marine carbon cycle, transforming and respiring organic carbon, regenerating nutrients, and acting as the final filter in sediments through which organic matter passes before long-term burial. Microbially-driven carbon cycling in the ocean profoundly affects the global carbon cycle, but key factors determining rates and locations of organic matter remineralization are unclear. In this study, researchers from the University of North Carolina at Chapel Hill will investigate the ability of pelagic microbial communities to initiate the remineralization of polysaccharides and proteins, which together constitute a major pool of organic matter in the ocean. Results from this study will be predictive on a large scale regarding the nature of the microbial response to organic matter input, and will provide a mechanistic framework for interpreting organic matter reactivity in the ocean.
Broader Impacts: This study will provide scientific training for undergraduate and graduate students from underrepresented groups. The project will also involve German colleagues, thus strengthening international scientific collaboration.";

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.
