ST. PETERSBURG - With support from the National Oceanic and Atmospheric Administration, National Marine Fisheries Service, scientists and technicians from the College of Marine Science and its Center for Ocean Technology, led by
Steve Murawski and Chad Lembke, have developed a unique towed camera array system (C-BASS) to allow high resolution sampling of reef fishes and simultaneous habitat evaluations. The primary motivation for the development of C-BASS is to develop absolute abundance estimates of reef fishes such as red snapper for use in setting fishery total allowable catch quotas.
Our system is equipped to process and record video from both analog and digital video cameras and currently 6 cameras are filming simultaneously. Environmental and system data sampled from an altimeter, compass, CTD, and fluorometer are also recorded. There is a laser system used to calibrate size measurements of the scenes being filmed and a Didson forward-looking sonar to detect fish movements in response to the C-BASS. The system was designed to operate in up to 250 meters of water (about 800 feet) but with modifications can be used much deeper. Two custom manufactured Bridgelux 85 watt array LED lights provide illumination for the video cameras during low light deployments. Scientific sensors, including a WETLabs FLNTU fluorometer and a Falmouth Scientific 2” Micro-CTD are installed on the frame in order to better understand the environmental aspects of the assessment. An altimeter is also mounted to the frame to ensure proper platform height above the seabed.
Initial trials and experiments with C-BASS have indicated that this system is highly capable of imaging reef fishes and assessing the habitat requirements of fishes encountered. This system has the potential to revolutionize the assessment and management of fisheries for reef fishes in Florida and throughout tropical areas of the world.
ST. PETERSBURG, FL - The American Association for the Advancement of Science (AAAS) has awarded the distinction of Fellow to three USFCMS faculty members among 347 scholars from around the nation.
AAAS is the world’s largest general scientific society and is an international non-profit organization “dedication to advancing science for the benefit of all people.”
Jacqueline E. Dixon: “For distinguished contributions to the fields of marine science and geology.”
Kendra Daly: “For distinguished contributions to the field of ocean science, particularly for advancing knowledge of Antarctic marine food webs and ecosystem dynamics in ice covered seas.”
Steve Murawski: “For distinguished contributions to the fields of fisheries and marine ecosystem science, particularly for theoretical and empirical contributions to understanding the dynamics of exploited ecosystems.”
AAAS will present its official certificate and a gold and blue rosette pin, representing science and engineering, in February at its annual AAAS Fellows Forum during the 2016 AAAS Annual Meeting in Washington, D.C. The formal announcement appears in the AAAS News & Notes section of the Nov. 25 issue of “Science” magazine.
ST. PETERSBURG, FL - Researchers from the University of South Florida College of Marine Science, along with colleagues representing institutions across the country and internationally, are set to embark on a 40-day research cruise through the Gulf Mexico to gather key data that will provide a more complete understanding of the destructive effects from two significant oil spills.
ST. PETERSBURG, FL - Congratulations to Dr. Steve Murawski's first graduating graduate students. During the December 2014 Graduate Commencement, USF President Judy Genshaft highlighted the accomplishments of Susan Snyder's work on the Deep Horizon Gulf Oil Spill.
