Limited effects of nutrient enrichment on bacterial carbon sources in salt marsh tidal creek sediments. Marine Ecology Progress Series. 544:107-130. 10.3354/meps11587 In June, August, and October 2013, intact sediment cores were collected from the mudflats of the fertilized and reference creeks at low tide (n=3 per creek in June and October, n=6 per creek in August; 31 cm diameter x 15 cm deep). These time periods reflected late spring, late summer, and early fall conditions. Sediment cores were transported to Woods Hole Oceanographic Institution\u2019s mesocosm system (Woods Hole, MA). Cores were placed in rectangular fiberglass tanks (2.7 m x 1.2 m x 0.8 m, l x w x d) that served as a water bath to minimize extreme fluctuations in day \u2013 night temperatures. The mesocosm system is located outside, so cores experienced ambient weather conditions. Upon placement in the fiberglass tanks, the overlying water collected with each sediment core was continuously recirculated (~9 cm deep). The cores acclimated to the mesocosm system for 1 \u2013 3 days, depending on weather, as we applied the\u00a013C label during sunny periods when BMA would be productive. Visible epifauna (e.g., snails, shrimp) were removed to minimize grazing on benthic microbes. At the beginning of each experiment, the overlying water column was removed and replaced with filtered water from the creek where the core was collected. We used 0.2 um filtered creek water to minimize label uptake by water column microbes and recirculated the water column to maintain well-mixed conditions. The isotopic label was added as \u00a013C-sodium bicarbonate (NaHCO3, 99 atom %, Sigma-Aldrich) to the water column of each core in June and October and half of the cores from each creek in August. The other half of the August cores received\u00a013C- labeled\u00a0S. alterniflora\u00a0detritus. This material was produced from a separate experiment in which living\u00a0S. alterniflora\u00a0plants from PIE- LTER were dosed with\u00a013CO2\u00a0for 3 h (Spivak & Reeve 2015). Aboveground leaves were harvested after label exposure, dried (60 deg C), and ground into a coarse powder that was evenly applied across the sediment surface.\u00a013C-S. alterniflora\u00a0was only applied in August due to availability of the labeled material. From here forward, experiments receiving \u00a013C-NaHCO3\u00a0or\u00a013C-S. alterniflora\u00a0are referred to as BMA or\u00a0S. alterniflora\u00a0experiments, respectively, to reflect the autotrophic source of carbon to bacteria. On average (+/- standard error, S.E.), the cores received 11.90 +/- 0.07 mg, 10.90 +/- 0.05, and 10.97 +/- 0.09 mg\u00a013C from NaHCO3\u00a0application in June, August, and October, respectively, and 3.17 +/- 0.12 mg\u00a013C from the\u00a0S. alterniflora\u00a0detritus in August. The\u00a013C label, as NaHCO3\u00a0or\u00a0S. alterniflora, was applied for four hours between 11:00 \u2013 15:00 h before the overlying water was removed and the cores were rinsed with at least three volumes of filtered creek water to remove unused label. The four hour sampling period was based on results from a preliminary study demonstrating that this timeframe was sufficient for detecting the label in algal and bacterial lipids. After the final rinse, the overlying water column was replaced with filtered creek water and recirculated for the duration of the experiments.\u00a0 Sediment samples for organic matter composition were collected by placing a hard plastic sleeve around a polyvinyl chloride (PVC) corer (5 cm diameter x 15 cm deep) and then removing the corer. The plastic sleeve remained in place to maintain the integrity of the sediment column and mark the core location (Spivak 2015). The top 0.5 cm of each core was collected into pre-combusted vials and frozen (-80 deg C) until analysis for total organic carbon and nitrogen content and stable isotopes (d13C, d15N) and lipid biomarker composition. Adjacent samples for benthic chlorophyll were collected with smaller cores (1.5 cm diameter x 1 cm deep) into glass vials and frozen (-20 deg C) until analysis. Additional sediment cores for organic matter composition and benthic chlorophyll were collected 4, 8, 24, and 48 h after the\u00a013C-labeled NaHCO3\u00a0was applied in June, August, and October and 4, 8, 24, and 144h after the\u00a013C-labeled\u00a0S. alterniflora\u00a0was applied in August.\u00a0 Lipid biomarker compounds were extracted using a modified Bligh and Dyer (1959) method. Sediment samples were extracted with a chloroform : methylene chloride : phosphate buffer saline mixture (2:1:0.8, v:v:v) using a microwave- accelerated reaction system (MARS6); samples were heated to 80 deg C for 10 min with continuous stirring. Following extraction, samples were partitioned and the organic phase was removed. The total lipid extract was concentrated under N2\u00a0and samples were separated on silica gel columns by eluting with chloroform, acetone (F1/2), and methanol (F3) (Guckert et al. 1985). The F3 (phospholipids) was dried under N2\u00a0and saponified with 0.5 M NaOH at 70 deg C for 4 h. Saponified samples were acidified and extracted three times with hexane. The extract was methylated with acidic methanol (95:5 methanol: HCl) and heated overnight at 70 deg C to form fatty acid methyl esters (FAME). Samples were analyzed with an Agilent 7890 gas chromatograph with an effluent split ~70:30 between a 5975C mass spectrometer and a flame ionization detector. Peaks were separated on an Agilent DB-5 ms column (60 m, 0.25 mm inner diameter, 0.25 um film). FAME concentrations were quantified using methyl heneicosanoate as an internal standard. FAs are designated A:BwC, where A is the number of carbon atoms, B is the number of double bonds, and C is the position of the first double bond from the aliphatic \u2018w\u2019 end of the molecule. The prefixes \u2018i\u2019 and \u2018a\u2019 refer to iso and anteiso methyl branched FAs and indicate whether the methyl group is attached to the penultimate or antepenulttimate carbon atoms (Bianchi & Canuel 2011).

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.
