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.

Angler-Driven Citizen Science: Monitoring Black Bass Populations in Arkansas
In Arkansas, the rugged terrain of the Ozark and Ouachita Mountains dominates the north and west, eventually yielding to the vast, fertile flatlands of the Mississippi River Delta to the east. Hundreds of reservoirs and lakes punctuate the landscape, while swift streams snake through the valleys and hills, eventually giving way to the slow-moving rivers and bayous in the south. The waterways of the state are teeming with life. Black bass dominate most of these ecosystems and have drawn anglers for centuries. The most sought-after fish in one of the country's most prominent fishing states, Arkansas treasures its black bass populations.

New Buoy Boosts White Lake’s Water Quality Monitoring and Conservation
White Lake in Western Michigan is a vestige of North America’s glacial past, and gets its name from an interpretation of the Indian, “Wabish-Sippe,” meaning the river with white clay. The twin towns of Whitehall and Montague, which nestle on White Lake’s shore, have shared a close connection with the lake since their foundation–from the growth of the lumbering industry, to industrializsation, the expansion of tourism, and most recently, environmental protection. The White Lake Association (WLA) was founded in 1988 by residents concerned about proposed development at the lake’s northern end.

Flow Photo Explorer: Studying Flows in the Penobscot River Basin
The flow dynamics of rivers and streams play an essential role in the chemical and physical functions of aquatic ecosystems. In Maine, varying flows in the Penobscot River Basin have impacted the health of the ecosystem, water resource use, and habitat suitability for native species—topics of particular concern to the Penobscot Indian Nation , who have been protecting and managing the waterway for millennia. Parts of the Penobscot basin have been monitored by the USGS stream gage network, which covers larger streams and rivers but excludes many of the small streams found on tribal lands.
