attribute NC_GLOBAL acquisition_description String Little Lagoon is a shallow coastal lagoon that is tidally connected to the\nGulf of Mexico but has no riverine inputs. The water in the lagoon is\nreplenished solely from precipitation and groundwater inputs primarily on the\nEast end (Su et al. 2012). Because of the rapid development in Baldwin County,\na large amount of NO3- enters the Little Lagoon system through SGD (Murgulet &\nTick 2008). In this region, there can be rapid changes in the depth to\ngroundwater (Fig. 4.1 inset) and episodic SGD inputs to the lagoon (Su et\nal.2013). Within the lagoon, three sites were selected (East, Mouth, and West)\nto represent the gradient that exists across the lagoon from the input of\ngroundwater. Sites were sampled on a near-monthly basis from February 2012 to\nFebruary 2013.\n \nBenthic fluxes from intact sediment cores\n \nAt each site triplicate intact sediment cores (270 mm x 95 mm ID; 190 mm\nsediment, 50 mm water column) were collected and setup in a flow-through\nsystem (Lavrentyev et al. 2000) in a darkened environmental chamber set to the\naverage site temperature within 8 hours of collection. The flow-through system\nconsisted of a multichannel proportioning pump that sent 0.7 micron filtered\nand ~100 \\u03bcM Na15NO3 - (99 atom %) enriched site water\n(\\u201cinflow\\u201d) at a continuous flow rate (1.2 mL min-1) to the overlying\nwater above the sediment surface. The positive displacement of the overlying\nwater exited the core through an outflow tube (\\u201coutflow\\u201d) and\ncollected in a reservoir. The volume of water overlying each sediment core was\nexchanged five times during a 24-hour incubation period to equilibrate the\ncores (Eyre et al. 2002). After the initial 24 hours, triplicate inflow and\noutflow samples were collected at 36 hours for dissolved gas and nutrient\nanalysis. Dissolved gas analysis followed the modified Isotope pairing\ntechnique (IPT) (Nielsen 1992, Risgaard-Petersen et al. 2003). In this\napproach, rates of 29N2 and 30N2 production from 15NO3 - are quantified and\nused to calculate rates of 14N2 production (p14) (equation 1, below); when\ncombined with 15N tracer slurry incubations (below), rates of anammox, and the\nrelative contribution of anammox and denitrification to p14 can be determined\n(equations 2-4, below).\n \nWater samples were collected in 12 mL Exetainers, allowing the vial to\noverflow two times the tube volume prior to preservation with 250 \\u03bcL of\n50% (w/v) ZnCl2 before being capped. Samples were stored under water in the\nenvironmental chamber until dissolved gas analysis on a membrane inlet mass\nspectrometer (MIMS) equipped with a copper reduction column set at 600oC to\nremove oxygen (O2) (Kana et al. 1998, Eyre et al. 2002). Benthic nutrient flux\nsamples were filtered (0.7 micron) and immediately frozen until DIN (NO2 -,\nNO3 -, NH4 +) and PO4 3- analyses as described above.\n \nSediment oxygen demand (SOD) was measured from oxygen concentrations in inflow\nand outflow water analyzed with a calibrated microelectrode and a Unisense\n\\u00ae multimeter analyzer. Denitrification and benthic flux calculations\n(\\u03bcmol m-2 hr-1) determined flux into or out of the sediment using the\ninfluent and effluent concentrations, flow rate (1.2 ml min-1), and the\nsurface area of the sediment (0.00708 m-2). All rates and fluxes pertaining to\nN species are expressed on a N atom basis. A positive flux indicates release\nfrom the sediments to the water column and a negative flux indicates uptake by\nthe sediment.\n \nAdditional methodology can be found in:\n \nBernard, Rebecca & Mortazavi, Behzad & A. Kleinhuizen, Alice. (2015).\nDissimilatory nitrate reduction to ammonium (DNRA) seasonally dominates\nNO3\\u2212 reduction pathways in an anthropogenically impacted sub-tropical\ncoastal lagoon.

attribute NC_GLOBAL projects_0_description String This project investigated the link between submarine groundwater discharge (SGD) and microalgal dynamics in Little Lagoon, Alabama.  In contrast to most near-shore environments, it is fully accessible; has no riverine inputs; and is large enough to display ecological diversity (c. 14x 0.75 km) yet small enough to be comprehensively sampled on appropriate temporal and spatial scales. The PIs have previously demonstrated that the lagoon is a hot-spot for toxic blooms of the diatom Pseudo-nitzchia spp. that are correlated with discharge from the surficial aquifer. This project assessed variability in SGD, the dependence of benthic nutrient fluxes on microphytobenthos (MPB) abundance and productivity, and the response of the phytoplankton to nutrient enrichment and dilution. The work integrated multiple temporal and spatial scales and demonstrated both the relative importance of SGD vs. benthic recycling as a source of nutrients, and the role of SGD in structuring the microalgal community.
