Texas Automated Buoy System
OCEANS 2009, 2009Co-Authors: Norman L. Guinasso, Leslie C. Bender, J.n. Walpert, Linwood L. Lee, Robert D. Martin, Robert D. Hetland, Steven K. Baum, Matthew K. HowardAbstract:The Texas Automated Buoy System (TABS) began in 1994 when the Texas General Land Office (GLO) funded the Geochemical and Environmental Research Group (GERG) at Texas A&M University to design and purchase five telemetering current meter Buoys. Instrumented Buoys continuously measure current velocity about six feet below the surface and transmit the data to shore on a regular schedule via satellite telephone. The System has eight Buoys funded by the TGLO operating along the Texas Coast — one near Sabine Pass, two off Galveston, one midway between Freeport and Corpus Christi, one off Corpus Christi, and two off Brownsville. The eighth Buoy, a three meter discus Buoy, was installed off Port Aransas in the summer of 2005 and removed in 2008. Two additional Buoys located near the Flower Garden Banks National Marine Sanctuary are funded separately by an oil industry consortium but are operated as part of the TABS program. Four different types of TABS Buoys are currently used by the program. All the Buoys can accommodate single point current sensors. The 2.25 and 3m and TABS Π Buoys can accommodate acoustic current profiling instruments and meteorological packages which include air temperature and humidity, barometric pressure, as well as wind speed and direction. The larger two Buoys have both mechanical and acoustic anemometers as well as accelerometers for measuring waves. The TABS I Buoys can be deployed in 10–20m water depth. The TABS II Buoys are suitable for deployment in 15m to 45m water depth. The two larger Buoys have been deployed in up to 110m water depth. Computers at Texas A&M University automatically collect data from the Buoys every two hours via the satellite data modems and make the observations available to GLO and the general public via the Internet. TABS data are made available to NOAA NDBC via ftp to permit the data to be used by the National Weather Service. TABS sites B, J, K N and V have been given NDBC designators 42043, 42044, 42045, 42046 and 42047 respectively. In 1998 a modeling component was added to the TABS program with the development and implementation of POM adapted to perform simulations on the Texas shelf. In 2002 the modeling was extended with the implementation of ROMS. Both models are run on a regular basis and output to a web page. Wind data from National Center for Environmental Prediction (NCEP) Eta-12 wind fields are used to drive the model in nowcast and forecast modes. Hurricanes have affected the Buoy System resulting in the loss of several Buoys at the deeper offshore locations. The TABS 2.25m Buoy was developed in an effort to deploy a Buoy that could survive hurricanes. In September, 2008, the eye of Hurricane Ike passed directly over Buoy V located near the Flower Garden Banks. The mechanical anemometer was damaged but the acoustic wind sensor gave a complete record of the storms passage. Wave and atmospheric pressure data were also recorded. Perhaps most interesting is the decrease of measured waves in the eye of the storm.

development operation and results from the texas automated Buoy System
Gulf of Mexico Science, 2007Co-Authors: Leslie C. Bender, Norman L. Guinasso, J.n. Walpert, Robert D. Martin, Robert D. Hetland, Steven K. Baum, Matthew K. HowardAbstract:The Texas Automated Buoy System (TABS) is a coastal network of moored Buoys that report near–real-time observations about currents and winds along the Texas coast. Established in 1995, the primary mission of TABS is ocean observations in the service of oil spill preparedness and response. The state of Texas funded the System with the intent of improving the data available to oil spill trajectory modelers. In its 12 years of operation, TABS has proven its usefulness during realistic oil spill drills and actual spills. The original capabilities of TABS, i.e., measurement of surface currents and temperatures, have been extended to the marine surface layer, the entire water column, and the sea floor. In addition to observations, a modeling component has been integrated into the TABS program. The goal is to form the core of a complete ocean observing System for Texas waters. As the nation embarks on the development of an integrated ocean observing System, TABS will continue to be an active participant of the Gulf of Mexico Coastal Ocean Observing System (GCOOS) regional association and the primary source of near-surface current measurements in the northwestern Gulf of Mexico. This article describes the origin of TABS, the philosophy behind the operation and development of the System, the resulting modifications to improve the System, the expansion of the System to include new sensors, the development of TABS forecasting models and real-time analysis tools, and how TABS has met many of the societal goals envisioned for GCOOS.

observing and forecasting coastal currents texas automated Buoy System tabs
OCEANS Conference, 2001Co-Authors: Norman L. Guinasso, Leslie C. Bender, J.n. Walpert, Linwood L. Lee, Robert D. Hetland, Matthew K. Howard, J Yip, R O Reid, D A Brooks, Robert D. MartinAbstract:The Texas Automated Buoy System operates Buoys at seven sites off the Texas coast from Brownsville to Sabine in water depths ranging from ten to one hundred meters. The System is supported by the Texas General Land Office as part of its mission to mitigate the effect of catastrophic oil spills on the Texas Coast. Buoys communicate surface currents and water temperature measured at 2m depth in near real time via cell phone and commercial satellite digital data links. One Buoy located at East Flower Garden Banks has a 300 kHz ADCP, a meteorology package with an ultrasonic acoustic wind velocity sensor, and a conductivity sensor. Data are posted regularly to a Web page http://www.gerg.tamu.edu/tglo and are available to the public and governments within a few hours after data collection. On the TABS Web page, a graphical map presentation of TABS current vectors has links to data tables and historical databases. Links are also provided to other data resources for oceanographic data in the Gulf of Mexico. Also on the Web page are links to an automated continental shelf forecast System that predicts currents over the Texas-Louisiana shelf on an operational basis. There are four major components in this System: (1) forecast wind field retrieving and preparation, (2) shelf circulation model module, (3) simulation plotting module and (4) Web display and file transfer module. The wind field used is a 3-hour interval ETA-22 forecast gridded wind from NOAA NCEP based on 00, 06, 12, and 18UTC model runs. The shelf circulation model is a 3-D version of Princeton Ocean Model (POM) on a domain extending from the coast to a curved line extending from 25/spl deg/N on the Mexican coast to 85/spl deg/W at the coastline of Florida. The operational POM model used at this time is a simplified barotropic version that permits us to reduce computational time to allow prediction of surface currents twenty-four hours into the future. The data vs. model comparison from April through December, 1999 of nine nearshore TABS Buoys indicates modest skill of the model in predicting the wind driven circulation. A fully baroclinic version of TABS-POM model is undergoing tests and will be implemented on an operational basis when sufficient computational resources become available. We are also developing data-assimilating models of the whole Gulf of Mexico and beyond to couple to our shelf model to supply outer boundary conditions.

This article describes the origin of TABS, the philosophy behind the operation and development of the System, the resulting modifications to improve the System, the expansion of the System to include new sensors, the development of TABS forecasting models and real-time analysis tools, and how TABS has met many of the societal goals envisioned for GCOOS.

Development, Operation, and Results From the Texas Automated Buoy System
Gulf of Mexico Science, 2007Co-Authors: Leslie C. Bender, Norman L. Guinasso, J.n. Walpert, Linwood L. Lee, Robert D. Martin, Robert D. Hetland, Steven K. Baum, Matthew K. HowardAbstract:The Texas Automated Buoy System (TABS) is a coastal network of moored Buoys that report near–real-time observations about currents and winds along the Texas coast. Established in 1995, the primary mission of TABS is ocean observations in the service of oil spill preparedness and response. The state of Texas funded the System with the intent of improving the data available to oil spill trajectory modelers. In its 12 years of operation, TABS has proven its usefulness during realistic oil spill drills and actual spills. The original capabilities of TABS, i.e., measurement of surface currents and temperatures, have been extended to the marine surface layer, the entire water column, and the sea floor. In addition to observations, a modeling component has been integrated into the TABS program. The goal is to form the core of a complete ocean observing System for Texas waters. As the nation embarks on the development of an integrated ocean observing System, TABS will continue to be an active participant of the Gulf of Mexico Coastal Ocean Observing System (GCOOS) regional association and the primary source of near-surface current measurements in the northwestern Gulf of Mexico. This article describes the origin of TABS, the philosophy behind the operation and development of the System, the resulting modifications to improve the System, the expansion of the System to include new sensors, the development of TABS forecasting models and real-time analysis tools, and how TABS has met many of the societal goals envisioned for GCOOS.

observing and forecasting coastal currents texas automated Buoy System tabs
OCEANS Conference, 2001Co-Authors: Norman L. Guinasso, Leslie C. Bender, J.n. Walpert, Linwood L. Lee, Robert D. Hetland, Matthew K. Howard, J Yip, R O Reid, D A Brooks, Robert D. MartinAbstract:The Texas Automated Buoy System operates Buoys at seven sites off the Texas coast from Brownsville to Sabine in water depths ranging from ten to one hundred meters. The System is supported by the Texas General Land Office as part of its mission to mitigate the effect of catastrophic oil spills on the Texas Coast. Buoys communicate surface currents and water temperature measured at 2m depth in near real time via cell phone and commercial satellite digital data links. One Buoy located at East Flower Garden Banks has a 300 kHz ADCP, a meteorology package with an ultrasonic acoustic wind velocity sensor, and a conductivity sensor. Data are posted regularly to a Web page http://www.gerg.tamu.edu/tglo and are available to the public and governments within a few hours after data collection. On the TABS Web page, a graphical map presentation of TABS current vectors has links to data tables and historical databases. Links are also provided to other data resources for oceanographic data in the Gulf of Mexico. Also on the Web page are links to an automated continental shelf forecast System that predicts currents over the Texas-Louisiana shelf on an operational basis. There are four major components in this System: (1) forecast wind field retrieving and preparation, (2) shelf circulation model module, (3) simulation plotting module and (4) Web display and file transfer module. The wind field used is a 3-hour interval ETA-22 forecast gridded wind from NOAA NCEP based on 00, 06, 12, and 18UTC model runs. The shelf circulation model is a 3-D version of Princeton Ocean Model (POM) on a domain extending from the coast to a curved line extending from 25/spl deg/N on the Mexican coast to 85/spl deg/W at the coastline of Florida. The operational POM model used at this time is a simplified barotropic version that permits us to reduce computational time to allow prediction of surface currents twenty-four hours into the future. The data vs. model comparison from April through December, 1999 of nine nearshore TABS Buoys indicates modest skill of the model in predicting the wind driven circulation. A fully baroclinic version of TABS-POM model is undergoing tests and will be implemented on an operational basis when sufficient computational resources become available. We are also developing data-assimilating models of the whole Gulf of Mexico and beyond to couple to our shelf model to supply outer boundary conditions.

TEXAS AUTOMATED Buoy System: REAL-TIME CURRENTS FOR OIL SPILL RESPONSE
International Oil Spill Conference Proceedings, 1997Co-Authors: Robert D. Martin, Linwood L. Lee, F. J. Kelly, Norman L. GuinassoAbstract:ABSTRACT If the question asked of the oil spill R&D community is, “What have you done for me lately?,” a solid answer is the Texas Automated Buoy System (TABS) and its contribution to the response effort in the 3000-barrel Buffalo Barge 292 oil spill. The TABS network consists of five automated Buoys anchored off the Texas coast that report half-hourly current measurements every 6 hours under normal conditions and every 2 hours during spill events. Public access to TABS is provided via an easy-to-use Internet Web page. Because of TABS, trajectory modelers knew the offshore currents within minutes of the Buffalo Barge 292 spill and were able to continuously track the currents along the Texas coast over the next 24 days. TABS also provided the first indications of a critical current reversal during the spill that allowed planners and managers to confidently stand down response preparations (and their associated costs) in some areas while redirecting response resources to truly threatened sections of the coa...

self powered intelligent Buoy System by water wave energy for sustainable and autonomous wireless sensing and data transmission
Nano Energy, 2019Co-Authors: Fengben Xi, Yaokun Pang, Shuwei Wang, Wei Li, Chi Zhang, Zhong Lin WangAbstract:Abstract Harvesting ocean wave energy is a killer application of triboelectric nanogenerator (TENG) for advantages in simple mechanism, high power density and high efficiency at low frequency. Here we report a self-powered intelligent Buoy System (SIBS), in which a high-output multilayered TENG is used for water wave energy harvesting. With a power management module, the output voltage can be converted and regulated as a steady DC voltage of 2.5 V for the operations of a microprogrammed control unit (MCU), several micro sensors and a transmitter. With the intelligent monitoring mechanism of the MCU, the harvested energy can be deployed for each sensor with different priority and data transmission cycle, and the SIBS can be at standby and active status by itself at different energy levels. At a wave frequency of 2 Hz, the SIBS can provide an average output power density of 13.2 mW/m2 and realize sustainable and autonomous wireless sensing for acceleration, magnetic intensity and temperature in range of 15 m, with amount of 19 bytes every 30 s. The SIBS has first demonstrated a complete TENG-based micro-energy solution for self-powered intelligent System, including energy harvesting, management, deployment and utilization, with an unattended manner and infinite lifetime. As a significant milestone for the TENG, this work has provided a universal platform for self-powered wireless sensor network nodes and exhibited broad prospects in internet of things, big data, artificial intelligence and blue energy.
