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.

该项目将支持在巴鲁克海洋野外实验室（BMFL）位于南卡罗来纳州北入口河口的主要长期研究地点购买最先进的水位测量系统。潮汐计所收集的数据，将用于加强及支援驻场及访问调查人员的研究工作。该潮汐计将是一个“完全集成的电子数据收集、处理和发布系统”，相当于美国国家海洋局（NOS）沿美国海岸线使用的“下一代水位测量系统”（NGWLMS），并可通过互联网访问。潮汐计将扩大研究地点和巴鲁克研究所现有的来自北入口河口的长期数据集（包括20年的NSF-LTER/NOAA-NERR数据）的实用性。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。由于BMFL现有的水位测量系统相对较差的精度（+/1 18毫米），对这些关于长期或短期水位变化（例如海平面上升、风暴潮等）的数据的解释受到限制。目前的系统也非常容易受到气压变化的影响，在极端低压事件（如飓风）期间，精度会降低到+/1 390毫米。一个更精确的水位系统（+/1 3mm）将为研究提供新的机会，利用现有的长期数据和新数据来检验假设。它还将刺激新的研究方向和合作，并将为North Inlet和其他已经存在类似设备的研究地点之间的比较研究提供新的机会。巴鲁克研究所已开始与NOS和南卡罗来纳大地测量局（SCGS）建立伙伴关系，部署、调平和维护潮汐计，以及管理和传播潮汐数据。指定的系统与国家水位观测网（NWLON）兼容，NOS将通过NOAA的地球同步运行环境卫星（GOES）提供与NWLON的连接。NWLON可以通过互联网访问，并提供基本的数据管理，以方便全球研究人员在近实时（1小时延迟）的情况下使用。SCGS将使系统达到现有的基准。BMFL将协调各项工作，并提供基础设施和日常维护。与BMFL现有的潮汐测量系统相比，该水位测量系统将在设计、精度、可用性和数据访问方面进行重大改进。
