Benthic pore water and sediment data Barnegat Bay, New Jersey, 2012-2013

This data set presents pore water nutrient concentrations and sediment oxygen demand (SOD) measurements made at 12 locations around the margin of Barnegat Bay and at 3 locations in central Barnegat Bay. The data were collected during 2012-2013 for the Barnegat Bay Nutrient Study in cooperation with the New Jersey Department of Environmental Protection. Table 1 presents the site data including site name, geographical location, site ID, and latitude and longitude. Table 2 presents concentrations of water quality constituents measured in water at the sediment interface and in pore water. Pore water was measured using in-situ equilibrium dialysis samplers (peepers) deployed at the stations. Measured concentrations in pore water were used to calculate nutrient flux rates between sediment pore water and overlying Bay water. Tables 3 and 4 present the composition and grain-size distribution of sediment from the benthic surface at the test sites. Table 5 presents SOD test results including date, water parameters, test duration, and the parameters used to develop best-fit least-square lines to the oxygen consumption data; these include slope (the SOD rate), intercept, correlation coefficient, and calculated SOD. These data support the following publication: Wilson, T. and DePaul, V., 2017, In situ benthic nutrient flux and sediment oxygen demand in Barnegat Bay, New Jersey, in Buchanan, G.A., Belton, T.J., and Paudel, B., eds., A Comprehensive Assessment of Barnegat Bay-Little Egg Harbor, New Jersey: Journal of Coastal Research, Special Issue 78, p. 46-59, https://doi.org/10.2112/SI78-005.1.

本数据集收录了巴内加特湾（Barnegat Bay）周边12个站位以及湾内中部3个站位的孔隙水营养盐浓度与沉积物需氧量（sediment oxygen demand, SOD）实测数据。本次数据采集工作于2012至2013年间开展，为配合新泽西州环境保护部（New Jersey Department of Environmental Protection）实施的巴内加特湾营养盐研究项目完成。

表1列出了各采样站位的基础信息，包括站位名称、地理位置、站位编号以及经纬度坐标。表2展示了沉积物界面水体与孔隙水中的水质组分浓度，其中孔隙水采用部署于各测站的原位平衡透析采样器（peepers）完成采集。实测孔隙水浓度被用于计算沉积物孔隙水与上覆湾水之间的营养盐通量速率。

表3与表4分别呈现了各试验站位底栖表层沉积物的组成与粒度分布特征。表5汇总了沉积物需氧量测试结果，涵盖测试日期、水体参数、测试时长，以及用于拟合耗氧数据最优最小二乘直线的相关参数；此类参数包括斜率（即沉积物需氧量速率）、截距、相关系数，以及计算得到的沉积物需氧量。
