Abstract:

PURPOSE. The objective of this Coastal Engineering Technical Note is to describe the Near-Real-Time NRT coastal data acquisition and processing capabilities that have been developed by the Prototype Measurement and Analysis Branch PMAB of the Coastal and Hydraulics Laboratory. These capabilities aid in data quality control and provide internally recorded and NRT wave, water-level, and current data products to Corps of Engineers CE sponsors. CE open-coast, inlet and harbor projects utilize the Prototype Measurement Analysis System PMAS for monitoring in support of design and operational engineering tasks. PMAS consists of coastal oceanographic sensors and instrumentation, communication equipment. and a relational database management system McKinney and Howell 1996. Figure 1 is a schematic representation of PMAS. In the figure, solid lines represent NRT data access. The term sensors may refer to NRT directional wave gauges DWG-1s Howell1992, 1993 or single pressure sensors. The term RTU refers to a Remote Transmission Unit which consists of the following a. An all-weather, protective housing. b. Cable connections linking an RTU to sensors for transferring data into the RTU. c. Data storage hardware and software and telecommunication hardware and software. d. Transferring data out of the RTU via radio or telephone line. The Automated Real Time Tidal Elevation System ARTTES provides offshore water level information to survey vessels and dredges using direct measurements coupled to a predictor correction processing program Lillycrop et al. 1991. The dashed lines going to NOAANDBC National Oceanographic and Atmospheric Administration National Data Buoy Center and DWG-ls indicate that data are received and inserted into PMAS but not in NRT mode. Data from NOAANDBC are received monthly.
