Satellite Company Provides Researchers With SPOT Satellite GPS Messengers(TM) to Complete an Unprecedented Oceanic Flow Study in Wake of Deepwater Horizon Oil Spill
COVINGTON, La., Nov. 8, 2012 (GLOBE NEWSWIRE) – Globalstar Inc. (GSAT) announced a partnership with the University of Miami to complete the Grand Lagrangian Deployment (GLAD), the largest research expedition studying ocean surface flow to date. Since summer 2012, researchers have placed more than 300 SPOT Satellite GPS MessengersTM into the Gulf with uninterrupted high-frequency tracking service. The Consortium for Advanced Research on Transport of Hydrocarbon in the Environment (CARTHE, carthe.org), which is funded by the Gulf of Mexico Research Initiative (GoMRI,gomri.org) program, intends to use the collected data to explain ocean flow as it relates to the dispersion of pollutants and the effects of hurricanes on the dissemination of environmental hazards over time.
“In light of the Deepwater Horizon incident and Hurricane Isaac, SPOT has transmitted ground-breaking data that may tell us how pollutants behave in normal and hurricane conditions,” said Dr. Tamay Ozgokmen, Director of CARTHE. “Oceanographers have never released 300 drifters at once. We did this in the area near the Deepwater Horizon and measured where and how fast the drifters moved, using high-precision tracking devices. This novel approach to understanding the Gulf’s unique ocean surface currents has implications for emergency responders and managers in the event of another oil spill, as well as human and environmental health.”
In order to study the complex and understudied currents near the Deepwater Horizon oil spill area, SPOT devices were mounted inside drifters that floated just below the ocean’s surface. CARTHE researchers want to understand how the Gulf’s flow may impact the transport of oil or pollutants along the surface of the ocean, particularly near coastal areas, which are especially vulnerable.
“The success of this study is largely due to quality and technology offered by the SPOT devices, which are providing CARTHE scientists better insight into how pollutant patches spread in the ocean,” said Dr. Ozgokmen. “Our custom-made ocean drifters had to be lightweight, low-cost and reliable. We couldn’t find a similar product that could match the price, size, battery life, reliability, transmission frequency and tracking accuracy of SPOT.”
In only three months, SPOT devices have provided CARTHE close to 5 million data transmissions on ocean circulation patterns at a scope and rate that is virtually unprecedented. Every five minutes, the devices relayed GPS coordinates with an accuracy within 4 meters. Other devices traditionally send tracking coordinates every thirty minutes. SPOT altered its standard tracking of every 10 minutes to meet the study’s unique needs.
Dr. Ozgokmen, Dr. Brian Haus, Lead GLAD Scientist, and other CARTHE researchers from more than 12 institutions around the world will use the data gathered from the SPOT devices via the Globalstar satellite network units to gain better insights into how oceanic flow transports pollutants. CARTHE’s data is being used to improve state-of-the-art ocean forecast models, which will provide more accurate predictions of where the oil may go and how fast it will get there. This is essential for effective emergency response as well as resource allocations in the event of another oil spill.
“Globalstar is delighted that SPOT’s GPS tracking services are being utilized as part of such an innovative research project that will have a significant impact on society and the environment,” said Bob Bennett, a representative for the Gulf Coast based satellite communications company.
SPOT devices are rugged, pocket-sized devices that use satellite messaging technology to allow users to communicate from remote locations around the globe. The SPOT product family uses the GPS satellite network to determine a customer’s location and to the Globalstar network of satellites to transmit messages and GPS coordinates to others, independent of cellular phone coverage or radio frequency range. As a result, SPOT devices fulfill a variety of purposes including emergency services, recreational tracking and scientific studies.
About the Consortium for Advanced Research on Transport of Hydrocarbon in the Environment (CARTHE)
The CARTHE project includes twenty-six principal investigators from twelve research institutions in eight states. Together these scientists are embarking in a novel research direction, developing a suite of integrated models and state-of-the-art data assimilation that bridge the scale gap between existing models and natural processes. This research project was made possible by a grant from The Gulf of Mexico Research Initiative (GoMRI). The GoMRI is a 10-year, $500 million independent research program established by an agreement between BP and the Gulf of Mexico Alliance (GOMA) to study the effects of the Deepwater Horizon incident and the potential associated impact of this and similar incidents on the environment and public health.
