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.

Questions & Answers
Does this sensor require temperature compensation?
Yes. The YSI ProDSS Total Algae Sensor needs to have a temperature sensor installed along with it for accurate readings.

Handheld Cyanotoxin Detection Technology Prototype

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.

Solar and Wind-Powered, Algae Tracking Boat Trialed in Florida

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.

Current Monitoring after the Francis Scott Key Bridge Collapse

On March 26th, according to The Baltimore Sun , a 984-foot, 112,000-ton Dali lost propulsion and collided with a support column of the Francis Scott Key Bridge, collapsing the structure. Soon after the event, search and rescue, salvage crews, and other emergency responders were mobilized after the collision. As salvage efforts progressed in early April, NOAA’s Center for Operational Oceanographic Products and Services (CO-OPS) responded to a request for real-time tidal currents data and deployed a current monitoring buoy—CURBY (Currents Real-time BuoY)—into the Patapsco River north of the Francis Scott Key Bridge.
