Overview
The Proteus is a unique, scientifically-proven multi-parameter probe platform that uses both fluorescence and patented algorithms to monitor biochemical oxygen demand (BOD), chemical oxygen demand (COD), total organic carbon (TOC), dissolved organic carbon (DOC) and total coliforms, fecal coliforms and E. coli coliforms in real-time. The instrument is designed for use in drinking water, wastewater, industrial, process, recreational swimming areas, aquaculture and food & beverage applications:
- Biochemical Oxygen Demand (BOD): BOD is a measure of the amount of oxygen that is used by bacteria and other microorganisms during the aerobic decomposition of organic matter.
- Chemical Oxygen Demand (COD): COD is a measure of the amount of oxygen that is required to dissolve both organic and inorganic matter with the water.
- Total Organic Carbon (TOC): TOC is a measure of the total amount of carbon present in organic compounds in a water source.
- Dissolved Organic Carbon (DOC): A subset of TOC, dissolved organic carbon is the fraction of TOC which can pass through a 0.22 - 0.7µm pore size filter.
- Total Coliforms, Fecal Coliforms and E. coli Coliforms: Coliforms are rod-shaped, gram negative bacteria. Total coliforms (TC) include all coliform bacteria that are present within the water source.
Sensor Options
Proteus can be fitted with up to 12 different sensors to output over 30 parameters on a single instrument. Sensor options include temperature, conductivity, pH, ORP, dissolved oxygen, turbidity, CDOM, tryptophan, chlorophyll, blue-green algae, depth, and more. A central wiper on the turbidity sensor cleans the optical sensors prior to each measurement, reducing the maintenance requirements when continuously deployed. The probe can also be outfitted with a cabled Bluetooth battery pack for spot sampling with any Android/iOS device.
Includes
Included with the purchase is the Proteus base unit with temperature sensor, calibration cup, sensor guard, serial communication cable, serial to USB adapter, digital manual and Proteus Software Manager. Both SDI-12 and RS-485 Modbus RTU are standard outputs for interfacing with environmental data loggers and PLC's. Pair the multi-parameter probe with the NexSens X-Series data loggers and CB-Series buoys for cloud-based data in remote locations via WQData Data LIVE and cellular or satellite telemetry.

Sargassum Surge: How Seaweed is Transforming our Oceans and Coastal Ecosystems
Until recently, Sargassum –a free-floating seaweed–was distributed throughout the Sargasso Sea , the north Caribbean Sea, and the Gulf of Mexico. But in the space of a decade, this seaweed has, as one scientist remarks , “Gone from a nonfactor to the source of a terrible crisis.” Driven by climate change, anomalous North Atlantic Oscillation in 2009-2010 and a glut of anthropogenic pollutants, sargassum has proliferated. Seasonally recurrent mats as deep as 7m now bloom in the “Great Atlantic Sargassum Belt” (GASB), which covers areas of the Atlantic from West Africa to the Caribbean Sea and Gulf of Mexico. Every year, millions of tons wash up along the shores of more than 30 countries . Dr.

According to the National Oceanic and Atmospheric Administration ( NOAA ), the Great Lakes have more miles of coastline than the contiguous Atlantic and Pacific coasts combined and contain 20 percent of the world's freshwater, making it a critical region to protect and conserve. Continuous monitoring and data-informed resource management are key components of managing waters in the region. Hayden Henderson, a research engineer with the Great Lakes Research Center (GLRC), designs and deploys monitoring platforms throughout the Great Lakes. With a background in environmental engineering, Henderson enjoyed the challenge of creating systems and making them work to obtain difficult, remote measurements.

Meadowbrook Creek in Syracuse, New York, has been monitored by Syracuse University (SU) faculty and students for over a decade. Originally established by Dr. Laura Lautz in 2012, the early years of the program focused on collecting grab water samples for laboratory analysis and evaluating the impact of urban land use, human activities, and natural processes on water resources. Tao Wen , an Assistant Professor in SU’s Department of Earth and Environmental Sciences, took over the program in 2020 and upgraded the existing systems to include 4G modems that allowed for real-time data viewing. [caption id="attachment_39339" align="alignnone" width="940"] An overview of the Fellows Ave monitoring station along Meadowbrook Creek.
