ANB Sensors has developed ground-breaking solid-state sensors for pH, conductivity & temperature. These innovative and revolutionary sensors, require no calibration, operate to depths of 50 meters in any orientation in fresh or saltwater environments.
Uniquely, they can be stored wet or dry, require simple maintenance, are extremely rugged and have exceptionally low on-going costs ideally suited for long term, cost effective remote monitoring in harsh and demanding environments. Thus, removing the fundamental issues seen with the conventional, fragile glass electrodes which require frequent manual calibration.
Calibration-Free: Unlike other pH sensors that need frequent re-calibration, ANB’s patented technology means that the sensor is automatically calibrated in-situ without the need for manual intervention.
Adaptable: These calibration-free pH sensors can be deployed autonomously or fit on any vehicle, sonde or monitoring platform.
Robust & Reliable: These solid-state sensors can be stored wet or dry without any degradation of performance, have no special handling requirements and operate in any orientation, delivering consistent & reliable performance in demanding environments.
Affordable: Being cost-effective and extremely low maintenance, these revolutionary sensors deliver up to 70% savings against operating costs of conventional sensors.
Intelligent: Constantly monitoring themselves these sensors provide real time feedback on sensor performance, continuously self-calibrating and automatically notifying an operator should user intervention be required.
Choice: 2 models are available for operating at different depths and applications, choose from sensors designed to operate up to 300m & 1250m depths.
Flexible: Automated operation for schedule and sample frequency plus manual command and sleep mode, data can be accessed via RS232 or RS485 communications, with analogue connectivity scheduled for future implementation.
Storage: Onboard 8GB memory allows storage of >15 million sensor readings of pH, conductivity, and temperature.
Biofouling: These sensors are designed to stop biofouling as standard, by electrochemically inhibiting the formation of biofilm on the transducer.

Climate Change and Microplastics: Monitoring Lake Champlain
Most people go to Lake Champlain for its exceptional views and thrilling boating, but it’s also home to a wide variety of interesting aquatic research projects. From studying microplastics to thermal dynamics of the lake, Timothy Mihuc, director of the Lake Champlain Research Institute (LCRI) at the State University of New York at Plattsburgh (SUNY Plattsburgh), has spent his career studying aquatic ecosystems. 
 
 As an aquatic biologist, he’s the main investigator on Lake Champlain’s research studies while also managing their grants, employees, and their hands-on buoy work. 
 
 Over the years, LCRI has received a number of environmental grants that aid in its monitoring research.

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.
Read MoreSoundscapes of the Solar Eclipse: Citizen Science Supporting National Research
On April 8, 2024, millions of people around the world had their eyes glued to the sky to witness a historic cosmic event. The total solar eclipse captured the headlines and the minds of many who became eager to gaze at the heavens as the sky went dark for a few minutes. However, not everyone used their sense of sight during the eclipse, some were listening to the sounds of the natural world around them as the light faded from above. 
 
 The Eclipse Soundscape Project is a NASA-funded citizen science project that focuses on studying how the annular solar eclipse on October 14, 2023, and the April 8, 2024 total solar eclipse impacted life on Earth. 
 
 The project revisits an initiative from the 1930s that showed animals and insects are affected by solar eclipses.
