14 st / October 2015 www.sea-technology.com tenance and precision are determining factors for a proj- ect, buoys that utilize pumping systems in a fow-through platform are often considered. With less frequent and less intensive maintenance programs, the operations and main- tenance cost of fow-through units are signifcantly more cost-effective. As the nature of these buoys lends them to protecting the internal equipment, users often see a lon- ger sensor life and more reliable and precise results. And, since pumping systems do not alter water quality prior to conducting measurements, the collected data are both ac- curate and precise, which is paramount to any monitoring program, regardless of the environment. ST oxygen, pH) and biological parameters (chlorophyll and blue-green algae), crude and refned oils, meteorological sys- tems, leak detection for internal system integrity checks, GPS reporting, and cabinet security for theft prevention. The communication system relays data in real time to the NEA data center, where the data are quality checked before being used in the water quality model. The buoys are ftted with 560 W of solar panels to power the instruments and pumping systems, which may run almost continuously. Each buoy is 8.5 ft. in diameter, with a focal plane height over 13 ft. to meet the maritime navigation aid requirements, along with navigation beacons, radar refectors and identifcation marks. NEA has submitted the project for several international awards, in recognition of the advanced nature of the national water quality monitoring and early warning system. Conclusion Open-water and fow-through monitoring platforms both provide effective monitoring solutions.

He received his B.A. in envi- ronmental and aquatic sciences from the University of Central Florida and worked as a consultant to the energy industry for environmental compliance and mitigation issues in the Gulf of Mexico. Danner also has design and feld experience with remote monitor- ing and remediation systems for nutrient abatement in lakes and ponds. Chris Goding is the business development manager at Pentair Environmental Systems. He holds a B.S. in industrial instrumentation and a graduate certifcate in project management. He has extensive experi- ence designing complex environmental monitoring systems, including measurement and controls, data logger or RTU programming, communications, and data presentation (SCADA). Goding was the lead project manager and integrator for Project Neptune in Singapore. Shorter Time to Survey Deliverables - New SeaBat T50-P ultra high resolution, portable multibeam echosounder The latest addition to the world-leading SeaBat T-series, the new SeaBat T50-P combines a wider swath with unprecedented data quality. Together with the Portable Sonar Processor, the SeaBat T50-P provides survey deliverables faster than ever before.
