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

该项目将支持在巴鲁克海洋现场实验室(BMFL)位于南卡罗来纳州北入海口的主要长期研究地点购买最先进的水位测量系统。从潮汐测量仪获得的数据将用于加强和支持BMFL常驻和访问调查人员的研究。潮汐测量仪将是一个“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。潮汐测量仪将扩大研究地点和巴鲁克研究所现有的来自北入海口的长期数据集(包括20年的NSF-LTER/NOAA-NERR数据)的用途。这些全面的长期数据集为非生物和生物因素在长期变化中的作用提供了洞察力。根据水位的长期或短期变化(如海平面上升、风暴潮等)对这些数据进行解释。BMFL现有的水位测量系统的精度相对较低(+/118 mm)，这一点受到了限制。目前的系统也非常容易受到气压变化的影响，在极低气压事件(如飓风)期间，精度会降低到+/1 390 mm。一个更准确的水位系统(+/1 3 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检验假设。它还将促进新的研究方向和合作，并将提供新的机会，以便在北水口和已有类似设备的其他研究地点之间进行比较研究。巴鲁克研究所已开始与美国国家海洋研究所和南卡罗来纳州大地测量局发展伙伴关系，以部署、调平和维护验潮仪以及潮汐数据的数据管理和传播。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(GOS)提供与NWLON的链接。NWLON可通过互联网访问，并提供基本数据管理，以便于世界各地的研究人员近乎实时(延迟1小时)使用。SCGS将把该系统提升到现有的基准。BMFL将协调努力，并提供基本基础设施和日常维护。这个水位测量系统将在设计、精度、可用性和数据访问方面比BMFL现有的潮汐测量系统有重大改进。

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.
