“…Circulation in this shallow, partially mixed system is driven primarily by wind and river discharge because the bounding barrier islands limit the oceanic connection (Luettich et al 2002). This creates generally long residence times that facilitate the microbial utilization and processing of excess watershed nutrients and organic matter, the result of anthropogenic enrichment and perturbation (Paerl et al 1998(Paerl et al , 2006b).…”

A 4 yr, spatially extensive study of the Neuse River and Pamlico Sound estuarine system, North Carolina, was used to evaluate the temporal patterns and bottom-up controls of the resident bacterioplankton community. This meso-to eutrophic estuarine system had high concentrations of dissolved and particulate organic matter and supported an active and abundant phytoplankton community. Temporal analysis of bacterioplankton productivity (BP) revealed a strong seasonal pattern, similar to water temperature. Comparisons of BP and several environmental variables grouped by season and year showed little correspondence between the bacteria and either river discharge or organic matter at either scale. Temperature explained about half of the variation in BP data, but without any obvious threshold in the semi-log temperature-productivity relationship, implying the absence of a shift to substrate limitation at higher temperatures. The temperature effect varied in space and was lower at the freshwater station, suggesting differential substrate availability or the presence of a different resident microbial community. Proxies for bacterial substrates, including dissolved organic carbon, particulate organic nitrogen, and chlorophyll a, improved the predictive power in multiple regression models, but at least one-third of the variation in BP remained unexplained. The regression models differed by station group, further highlighting the possible difference in biota and/or resources between the freshwater and brackish sites.

“…1). Flows are dominated by wind and river inflow, rather than tides (Luettich et al 2002). Five stations were sampled, covering a 55-km stretch of the estuary: stations 0, 30, 70, 120, and 180.…”

Abstract. Bacterioplankton response to eutrophication is a critical part of the transition from phytoplankton blooms to bottom-water hypoxia in estuaries. This topic is of particular concern when endemic bacterial populations, such as Vibrio sp., may pose a health risk to local human populations using estuaries for recreation and food. The purpose of this study was to observe the dynamics of both Vibrio and phytoplankton in the Neuse River Estuary (NRE) in North Carolina, USA, during the summer of 2004. Vibrio concentrations, particle suspension characteristics, and chlorophyll a were measured in surface water collected at a series of stations along the estuarine gradient. Consistent with previous studies, a strong positive relationship between Vibrio concentration and salinity was found. Both Vibrio sp. and phytoplankton concentrations increased moving downstream, but beyond the salt front, phytoplankton declined while Vibrio sp. concentrations continued to increase. In surface waters, a large portion of suspensions was comprised of phytoplankton cells. The fraction of Vibrio cells attached to phytoplankton increased with phytoplankton concentration and decreased with increasing salinity. These observations of Vibrio dynamics in the NRE provide evidence that populations interact with phytoplankton populations in surface waters. This information may prove critical for models of estuarine bacterial dynamics in response to eutrophication.

“…This restricted flow limits astronomical tides and creates the lagoonal nature of the APES. Wind forcing primarily drives water circulation in the major sounds and estuaries (e.g., [28][29][30]). Given the large surface area, shallow bathymetry with broad shoals, and alignment of the long axis of Pamilco Sound with the prevailing wind direction [29], a dominate feature of the APES as frequently observed in remotely sensed images or field observations is the moderate-to-high concentration of suspended material or turbidity throughout most of the system's water bodies.…”

A Multi-Sensor Approach to Examining the Distribution of Total Suspended Matter (TSM) in the Albemarle-Pamlico Estuarine System, NC, USA

For many coastal waters, total suspended matter (TSM) plays a major role in key biological, chemical and geological processes. Effective mapping and monitoring technologies for TSM are therefore needed to support research investigations and environmental assessment and management efforts. Although several investigators have demonstrated that TSM or suspended sediments can be successfully mapped using MODIS 250 m data for relatively large water bodies, MODIS 250 m data is of more limited use for smaller estuaries and bays or aquatic systems with complex shoreline geometry. To adequately examine TSM in the Albemarle-Pamlico Estuarine System (APES) of North Carolina, the large-scale synoptic view of MODIS and the higher spatial resolution of other sensors are required. MODIS, Landsat 7 ETM+ and FORMOSAT-2 remote sensing instrument (RSI) data were collected on 8 November, 24 November and 10 December, 2010. Using TSM images (mg/L) derived from MODIS 250 m band 1 (620-670 nm) data, Landsat 7 ETM+ 30 m band 3 (630-690 nm) and FORMOSAT-2 RSI 8 m band 3 (630−690 nm) atmospherically corrected images were calibrated to TSM for select areas of the APES. There was a significant linear relationship between both Landsat 7 ETM+ (r 2 = 0.87, n = 599, P < 0.001) and FORMOSAT-2 RSI (r 2 = 0.95, n = 583, P < 0.001) OPEN ACCESSRemote Sens. 2011, 3 963 reflectance images and MODIS-derived TSM concentrations, thus providing consistent estimates of TSM at 250, 30 and 8 m pixel resolutions. This multi-sensor approach will support a broad range of investigations on the water quality of the APES and help guide sampling schemes of future field campaigns.
