Overview
The SonTek-SL (affectionately known as the Side-Looker or "SL") has earned worldwide acceptance as a long-term monitoring solution. Now, with two new (3G) models turbo-charged by the proprietary SmartPulseHD, the SonTek-SL features accessories, mounting options, software, and a variety of integration formats to ensure it fits the desired application.
Design
Designed specifically for side mounting on bridges, canal walls, or riverbanks, the SL's sleek, low-profile housing makes installation easy. With three models to choose from, the SL can be used in wide or narrow channels. Ultra narrow beam widths combined with unmatched side lobe suppression provide the superior acoustic directivity necessary for achieving maximum horizontal range free of interference from surface or bottom boundaries.
Mechanics
First time users can collect test data within minutes of receiving the SonTek-SL. Deployments require only a few minutes to configure the SL and start collecting data. This system provides the highest quality Doppler velocity data without requiring the user to become an expert on Doppler technology.
Benefits
- SmartPulseHD (3G models only): An intelligent algorithm that looks at water depth, profiling range, velocity, and turbulence, and then acoustically adapts to those conditions using pulse-coherent, broadband, and incoherent techniques. Best data possible under any condition. High-def cell sizes down to 4 cm.
- Compact, Hydrodynamic Design: Incredibly lightweight and easy to transport and mount. Slim shape is easy to maintain, stays clean, increases available sample area, and fits into more places.
- Water Velocity Profiling: Customizeable, flexible setup options to suit a variety of applications. 3G models offer 128-cells for high-resolution and detailed profiles.
- Acoustic-Pressure "Duo" Water Level (3G models only): Not only redundant sources of water level, the acoustic vertical beam and pressure sensor continually self-check, and pressure data are auto-corrected to keep atmospheric offset negligible.
- Versatile, Easy Mounting: Easy-access side mounting reduces concerns over personnel safety, lowers operational cost by avoiding divers and boats, avoids interruption in facility operations, and avoids interruption in data and water delivery to clients and stakeholders.
- Wave Spectra Option: Integrated pressure sensor calculates and outputs wave-height and period, in real-time.

Testing CO2 Removal Strategies in the Pacific Northwest
The ocean plays a key role in carbon dioxide (CO2) removal and storage, also known as carbon sequestration. However, with increasing emissions, a large amount of CO2 escapes into the atmosphere, worsening climate change and leading to increases in surface temperatures. In order to mitigate some of these impacts, researchers like Ally Savoie at the Pacific Northwest National Laboratory (PNNL) are working hard to identify ways to safely improve the CO2 removal and storage capabilities in the ocean. Savoie started her career at Wright State University , where she worked in Silvia Newell’s lab examining biogeochemical cycling of nutrients in a river system. From there, she decided to pursue a master’s in marine science at the University of Southern Mississippi with Dr.
Smart Buoys Advance Climate Monitoring in Swiss Lakes
Lakes are sentinels of climate change . Globally, they are warming at an unprecedented but uneven rate, and in many places they also face direct human pressure, including from agriculture and recreation. In the Alps, scientists generally agree that climate change is of particular threat to remote lakes , where more pronounced warming threatens fragile ecosystems. Alpine Lakes in a Changing Climate Matteo Tonellotto is part of the team at the Environmental Observatory of the Italian-speaking region of Switzerland (OASI)–a multidisciplinary team of scientists, IT specialists, and chemical laboratory technicians committed to collecting, managing, and integrating high-quality environmental data.
Connecting with Nature in Real-Time at the Abernathy Field Station
Just five miles away from Washington and Jefferson (W&J) College is the 57-acre Abernathy Field Station . Generously donated by the Abernathy family in 2017, the field station has served as an outdoor lab to hundreds of undergraduate students over the years. Many classes use the Abernathy Field Station every week. For example, in BIO 111, students spend 15 weeks conducting their own research at the field station using a combination of sampling, field observations, and real-time environmental data, giving them a look into the world of science and a closer relationship with nature. “We like to start the students in the research process in their first Biology class.
Riding the Renewable Wave: Testing Wave Energy Converters at Oregon’s PacWave Site
Seven miles off Oregon’s weather-beaten coastline, the world’s biggest wave power testing facility, PacWave, is primed to put the latest renewable energy technology to the test. “There is a huge amount of energy that is not harvested in the ocean,” states the team at Oregon State University involved in the PacWave project. When it comes to harnessing the power of the waves, “It's exciting because it [wave power] is a non-polluting, non-carbon burning technology,” the team says. Wave Power The U.S. Energy Information Administration explains that tidal energy harnesses the flow of seawater in depth under the gravitational forces exerted by the sun and moon–the drivers of tides–while wave energy derives from the kinetic energy of wind-blown surface waves.
