The WL16 is a data logger and submersible pressure transducer combination designed for remote monitoring and recording of water level or pressure data. The water level logger can record over 81,000 readings and has four unique recording options, fast (10 samples per second), programmable interval (1 second to multiple years), logarithmic, and exception. Multiple depth ranges are available from 3 ft to 500 ft of water level change. A 25 ft vented cable is standard, and optional cable lengths are available from the factory up to 500 ft.
The WL16 Water Level Logger is housed in a weather-resistant cylindrical enclosure, which slips inside a standard 2-inch PVC pipe. The WL16 is easily adapted with standard hardware for wellhead mounting, stream, or other installations. Two internal 9 VDC alkaline batteries will typically power the WL16 for approximately one year even if one of the batteries fails. A third on-board battery ensures your data in the event both 9V batteries fail. The WL16 includes software for Windows computers, allowing easy data transfer to a laptop or desktop.

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.

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.
Read MoreCrystal 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.
