The Hydreon RG-15 Solid State Tipping Bucket is a rainfall measuring device intended to replace conventional tipping buckets. The RG-15 is rugged, reliable, maintenance-free and features a nominal accuracy of within 10%. The RG-15 is designed to replace tipping bucket rain gauges in many applications where their maintenance requirements make them impractical.

The RG-15 uses beams of infrared light within a plastic lens about the size of a tennis ball. The round surface of the lens discourages collection of debris, and the RG-15 has no moving parts to stick, and no water-pathways to clog. The device features an open-collector output that emulates a conventional tipping bucket, as well as serial communications that provide more detailed data and allow for configuration of the device.

The RG-15 may be configured through the serial port, or optionally via DIP switches. Power consumption of the RG-15 is very low, and the device is well-suited to solar-power applications. Dip Switches can control the units (inches or millimeters) and resolution (0.01″/0.2mm or 0.001″/0.02mm) of the device. Commands can also be sent via the RS232 serial port to override them.

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.
