PME Cyclops-7 Logger

The PME Cyclops-7 Logger is a self-contained data logging package for unattended monitoring. The Cyclops-7 Logger software allows the user to conduct sensor calibration as well as create visual plots of the data collected. The software is easily installed and operated.

The outer case of the Cyclops-7 Logger is constructed from Delrin, a hard and durable plastic material that does not easily crack or break. All internal circuitry and sensor components have been specifically designed to fit on the logger's spine. The batteries, SD card, on/off switch, circuit board, and other components are attached to a chem film aluminum spine.

Questions & Answers
Can the sampling rate be changed for the logger?
Yes, the default is 10 minutes although with the Cyc7 Control program, users can define sampling rates. The rate must be at least 1 minute and no more than 60 minutes. The program is stored in the logger from the factory.
Is the logger completely waterproof?
The unit is rated for submersion and unattended monitoring although the battery compartment must remain completely sealed to prevent pressure discharges from water incursion in the battery compartment during deployment.
Are the sensors calibrated prior to shipping?
No, 2-point calibrations should be carried out using the Cyc7Control.jar program, which is stored in the logger.
What is the expected lifespan of the PME Cyclop-7 Logger?
With proper care, maintenance and calibrations PME Loggers can operate well beyond 5 years.

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.
