FSML- A State-of-the-art Water Level Measurement System for the Baruch Marine Laboratory

该项目将支持在位于南卡罗来纳州北入口河口的巴鲁克海洋现场实验室（BMFL）主要长期研究地点购买最先进的水位测量系统。 验潮站所得的数据，将用于加强和支持驻港和访港研究员的研究工作。 验潮仪将是一个“完全集成的电子数据收集、处理和传播系统”，相当于国家海洋局（NOS）沿着美国海岸线使用的“下一代水位测量系统”（NGWLMS），可通过互联网访问。 验潮仪将扩大研究地点和巴鲁克研究所现有的北入口河口长期数据集（包括20年的NSF-LTER/NOAA-NERR数据）的用途。 这些全面的长期数据集提供了对非生物和生物因素在长期变化中的作用的见解。 根据水位的长期或短期变化对这些数据进行解释（例如，海平面上升、风暴潮等）BMFL现有水位测量系统的相对较差的精度（± 118 mm）限制了该测量系统。 目前的系统还非常容易受到大气压力变化的影响，在极端低压事件（例如，飓风）。 一个更精确的水位系统（+/13 mm）将为研究提供新的机会，利用现有的长期数据和新的数据来测试假设。 巴鲁克研究所已开始与美国海洋观测系统公司和南卡罗来纳州大地测量局建立伙伴关系，以部署、调平和维护验潮仪，并进行数据管理和潮汐数据传播。 指定的系统与国家水位观测网络（NWLON）兼容，NOS将通过NOAA的地球静止运行环境卫星（GOES）提供与NWLON的链接。 NWLON可通过互联网访问，并提供基本的数据管理，以方便世界各地的研究人员在接近真实的时间（1小时延迟）使用。 SCGS将使系统达到现有基准。 BMFL将协调工作，并提供基本的基础设施和日常维护。 这一水位测量系统将在设计、准确性、可用性和数据访问方面对BMFL现有的潮汐测量系统进行重大改进。

This project will support the acquisition of a state-of-the-art water level measurement system at the Baruch Marine Field Laboratory's (BMFL) primary long-term research site in North Inlet Estuary, South Carolina. Data obtained from the tide gauge will be used to enhance and support research by resident and visiting investigators at the BMFL. The tide gauge will be a "fully integrated electronic data collection, processing and dissemination system" equivalent to the "Next Generation Water Level Measurement System" (NGWLMS) used by the National Ocean Service (NOS) along the US coastlines and accessible via the Internet. The tide gauge will expand the usefulness of the research site and the Baruch Institute's existing long-term data sets from North Inlet Estuary (including 20 years of NSF-LTER/NOAA-NERR data). These comprehensive long-term datasets have provided insights into the role of abiotic and biotic factors in long-term change. Interpretation of these data with respect to either long-or short-term changes in water level (e.g., sea level rise, storm surges, etc.) has been limited by the relatively poor accuracy (+/1 18 mm) of the BMFL's existing water level measurement system. The current system is also highly susceptible to changes in barometric pressure, decreasing accuracy to +/1 390mm during extreme low pressure events (e.g., hurricanes). A more accurate water level system (+/1 3mm) will provide new opportunities for researches to test hypotheses using both existing long-term data and new data. It will also stimulate new research directions and collaborations and will provide new opportunities for comparative research between North Inlet and other research sites where similar equipment already exists.The Baruch Institute has begun to develop partnerships with NOS and the South Carolina Geodetic Survey (SCGS) for deployment, leveling and maintenance of the tide gauge as well as data management and dissemination of tide data. The system specified is compatible with the National Water Level Observation Network (NWLON) and NOS will provide a link to the NWLON via NOAA's Geostationary Operational Environmental Satellites (GOES). The NWLON is accessible via the Internet and provides basic data management to facilitate use by researchers worldwide in near real time (1 hr delay). The SCGS will level the system to existing benchmarks. The BMFL will coordinate efforts, and provide the basic infrastructure and day-to-day maintenance. This water level measurement system will be a major improvement in design, accuracy, availability, and access of data over the BMFL's existing tidal measurement system.
