The Torrent Board was developed by Xylem in conjunction with a team of SonTek RiverSurveyor M9 and S5 users, consisting of hydrologists and surfboard designers. The Torrent Board has been designed for use across the velocity ranges including high velocity conditions.

The low drag, deep V keel and double concave of the board enables any entrapped air to pass either side of the instrument minimizing aeration.

The Torrent Board has been successfully deployed in the field, in velocities up to 4m/s and yet still performs in really low velocities. It also comes with a drag anchor to assist manoeuvring in difficult low velocity and eddy situations.

The Torrent Board is supplied with all fixings and a handy soft case with rucksack-style straps to easily transport the board and RiverSurveyor system across rough terrain with ease.

The Birds and the Bees: Understanding the Diversity of Pollinators

Pollinators of all shapes and sizes are vital to ecosystems around the world. From the wide array of food people eat to the diversity of life around the planet, life would be very different without them. Pollinators are organisms that help carry pollen from one plant to another, and over 350,000 species can be found worldwide, according to The California Department of Fish and Wildlife . With the strong relationship between plants and pollinators, losing either would have detrimental impacts on ecosystems.  Over millions of years, both plants and pollinators have evolved alongside each other and formed unique adaptations that allow them to work together, expediting and enhancing the process of pollination.

Monitoring Volcanic Activity in Hawaii: Safeguarding Public Safety with the Hawaiian Volcano Observatory

The eight main Hawaiian Islands are made up of 15 volcanoes, six of which are active as of 2023 . Many locals live on or near an active volcano, making the monitoring and understanding of volcanic activity a core issue of public safety on the islands. Organizations like the Hawaiian Volcano Observatory (HVO) have spent decades monitoring the islands’ volcanoes to protect the public, develop a deeper understanding of the islands’ volcanos and forecast eruptions whenever possible. Even those who live away from edifices like Mauna Loa often have connections to the people living near the volcano.

Crystal Clear Problems: Impacts of Water Transparency in Aquatic Ecosystems

From crystal clear alpine lakes to muddy rivers and boggy swamps, water transparency is an easily observable water quality parameter to anyone who takes a few moments to peer into the (sometimes) murky depths. Water transparency varies dramatically based on the location of bodies of water among different watershed environments, but it can also change quickly due to a variety of internal and external factors. At Miami University (OH), the Global Change Limnology Lab explores the many ways that water transparency impacts aquatic ecosystems. Operational for nearly 20 years, the lab trains undergraduate and graduate students and has conducted work from the midwest Great Lakes to Alaska, South America and New Zealand.  The Global Change Limnology Lab, headed by Dr.
