“…The average depth is 4.6 m and bottom sediments are composed of silt, clay and sand. The Roanoke River supplies more than half the total freshwater input to Albemarle Sound (Bales et al, 1993). Prior to the construction of a series of large hydropower dams, the section of the Roanoke River between river kilometer (rkm) 206 and 242 was considered by Carnes (1965) to be the fall zone, the high-gradient transition between the Piedmont and Coastal Plain provinces ( Fig.…”

“…Background. Habitat quality could be a limiting factor for juvenile Atlantic sturgeon within Albemarle Sound because of the lack of deepwater thermal refugia during periods of peak (30°C) water temperature (Bales et al, 1993;Haeseker et al, 1996). However, an advantage of the shallow water is that the sound is generally well mixed in late summer and tends to be normoxic (Haeseker et al, 1996).…”

“…InVEST requires an economic valuation input table to calculate the avoided cost of nitrogen removal. 2 We calculated the value of N retained using three approximations of value: benefits transfer from Jenkins et al (2010); average and median marginal Bales et al, 1993;Hartigan et al 1983;USEPA, 1983;Line et al 2002;Loehr 1974;Barren Land 12.4;0 Dodd et al 19920.5-12.4 Dodd et al, 1992Loehr 1974;Forest 11.4;0.6 Line et al 2002;Breemen et al 20021.6-11.4 Dodd et al 1992Beaulac and Reckhow, 1982;Line et al 2002;Rast and Lee 1978;Loehr et al 1989 abatement costs of the 18 POTWs (Kessler, 2010); spatially allocated marginal abatement costs by tributary (Kessler, 2010). We included the benefits transfer because it represents an actual range of the cost of marginal trade for nitrogen reduction credits that could potentially be devised for our study region.…”

a b s t r a c tGlobally, managers are trying to prevent or halt the eutrophication of valuable estuaries and bays by reducing nutrient inputs, but justifying the cost of conservation or processing facility upgrades often proves challenging. We focus on a coastal watershed in Maine and New Hampshire struggling with the financial burdens of nitrogen pollution mandates due to the eutrophication of the Great Bay estuary. After creating two future watershed land cover scenarios comparing plausible extremes, we ran them through two models, the Natural Capital Project's InVEST (Integrated Valuation of Ecosystem Services and Tradeoffs) and a detailed hydrologic and biogeochemical river network model FrAMES (Framework for Aquatic Modeling of the Earth System). Through this work, we both evaluated and valued the ecosystem service of nitrogen retention. We find that both models provide numerical arguments for conservation efforts, and decision makers would benefit from using either an ecosystem services model or a biogeochemical model when dealing with complex issues like nutrient overenrichment. According to both our modeling results, modest watershed conservation efforts as defined by our expert stakeholders, ie: protecting wetlands and forests, could reduce the amount of total nitrogen entering the Great Bay estuary in the range of 3-28 metric tons per year.

During 1993–1994, 78 adult striped bass Morone saxatilis captured in the Albemarle Sound–Roanoke River (AR) system were tagged with ultrasonic transmitters to examine summer patterns of distribution, migration, and habitat selection. Additionally, 626 striped bass were collected by electrofishing during 1993 to assess summer condition. Water temperatures within Albemarle Sound rose well above suitable levels for striped bass, but dissolved oxygen remained within tolerance limits. No stratification of temperature or dissolved oxygen occurred and no substantial thermal refuges were located. Telemetered striped bass were found throughout the Albemarle Sound system, selecting for deep water or structure. No evidence of migration to the Atlantic Ocean was found. During summer AR striped bass 325 mm total length or longer were in relatively poor condition, as evidenced by the extensive occurrence of red dermal lesions and ectoparasites. Relative weight (condition based on a standard weight at length) of commercially caught AR striped bass varied seasonally, exhibiting low values during May–August but normal values for the remainder of the year.
