The Global Water GL500 multi-channel data logger features 7 analog channels and 2 digital channels for data recording. The GL500 can record over 40,000 readings and has four unique recording options, fast (10 samples per second), programmable interval (1 second to multiple years), logarithmic, and exception. The data logger also has a sample on demand input that triggers a recording of special events, such as when a water sampler was triggered, when a door was opened, etc. Daily start and stop alarm times can be programmed to limit recording intervals during a day. The GL500 includes Windows software, allowing easy upload of data to a laptop or desktop.

An optional version with integrated Bluetooth 2.0 allows users to access data and settings without the use of a custom connection cable. Using a laptop or desktop computer with Bluetooth capability, the data logger's data and settings can be viewed, stored and programmed using the Global Logger II desktop software package, as well as the Flow Monitor software. All of the features in these data logger software packages are available using the Bluetooth interface. Because the Bluetooth module draws power when turned on, the data logger features a power switch to turn it off when not in use.  A red LED indicates when the data logger's Bluetooth module is on and a blue LED shows the status of the Bluetooth connection.

The GL500 data logger is setup to accept any 4-20mA sensor and provides switched power to the sensors based on the sample interval and sensor warm up time settings. Twisted pair 2-wire and 3-wire sensors can be quickly connected to the data logger's terminal strip and calibrated via the Global data logger software. Sensors can be accessed through dial-out to a remote modem attached to the GL500's serial communication port. The data logger software has online help files that are easily accessed using drop down menus and links to quickly find the answers to questions.

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.
