YSI ProDSS Total Algae Sensor
- Dual channel sensor
- Measures and outputs both chlorophyll & blue-green algae
- Options for ug/L and RFU outputs
The Total Algae (TAL) sensors are dual-channel fluorescence sensors. The “channels” are for chlorophyll and phycocyanin (TAL-PC), or chlorophyll and phycoerythrin (TAL-PE), which are measured in the water. Each sensor thus yields two data sets: for TAL-PC, one results from a blue-emitting LED that excites the chlorophyll a (chl) molecule and the second results from an orange excitation beam that excites the phycocyanin (PC) accessory pigment. The TAL-PE sensor is similar, also having the chlorophyll channel, but rather than an orange-emitting LED there is a slightly blue-shifted beam that excites phycoerythrin (PE).
The TAL sensors generate data in RFU or μg/L of pigment (chl, PC or PE) units, with RFU as the default. When using either RFU or μg/L, the sensor’s response is highly linear: a reading of 50 of either unit represents twice as much fluorescence detected as a reading of 25, for example, if the temperature is constant.

In the battle against harmful algal blooms (HABs), time is important . The need for laboratory equipment and testing is a serious challenge for water managers. This issue caught the eye of Qingshan Wei , an assistant professor of chemical and biomolecular engineering at North Carolina State University .
“Our research group is interested in developing low-cost sensors,” Wei told EM . “Recently we have been developing sensors for environmental monitoring, and cyanotoxins came to our attention .”
Cyanobacteria, which generate HABs, are becoming a challenge across the US . They are a very serious problem in North Carolina, in part due to the weather.Read More
Time is of the essence when it comes to tracking algal blooms, and people everywhere are looking for solutions. In Florida, scientists from Florida Atlantic University Harbor Branch Oceanographic Institute (HBOI) recently trialed a solar-powered, algae-tracking sail boat developed by Navocean , Inc. Dr. Jordon Beckler of Florida Atlantic University (FAU) directs HBOI's Geochemistry and Geochemical Sensing Lab and spoke to EM about the trials and the boat.
"This boat is so amazing when you see it in action," remarks Dr. Beckler. "Navocean originally contacted me a few years back about a demonstration when I was over at my previous institution in West Florida, and we brainstormed some scenarios for employing the boat for harmful algae bloom monitoring.Read More
It is no secret that in today's world, most scientists do not stick exclusively to science–they must be educators, communicators, and advocates. The looming threats facing the planet's climate and the growing distrust in science by the public have forced scientists to expand and improve their capacity for science communication to the world.
From repeatedly testifying before the U.S. Congress to winning an Emmy as the Chief Scientific Advisor for an award-winning nature documentary, marine ecologist James W. Porter has been thrust into the public eye.Read More
