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.

Solar and Wind-Powered, Algae Tracking Boat Trialed in Florida
Time is of the essence when it comes to tracking algal blooms, and people everywhere are looking for solutions. In Florida, scientists from Florida Atlantic University Harbor Branch Oceanographic Institute (HBOI) recently trialed a solar-powered, algae-tracking sail boat developed by Navocean , Inc. Dr. Jordon Beckler of Florida Atlantic University (FAU) directs HBOI's Geochemistry and Geochemical Sensing Lab and spoke to EM about the trials and the boat. "This boat is so amazing when you see it in action," remarks Dr. Beckler. "Navocean originally contacted me a few years back about a demonstration when I was over at my previous institution in West Florida, and we brainstormed some scenarios for employing the boat for harmful algae bloom monitoring.

CICHAZ Biological Field Station Provides A Unique Educational and Research Experience in Mexico’s Huasteca Region
The story of the Centro de Investigaciones Científicas de las Huastecas "Aguazarca" (CICHAZ) Biological Field Station, a member of the Organization of Biological Field Stations ( OBFS ), starts with Dr. Gil Rosenthal, Professor of Biology and Chair of Ecology and Evolutionary Biology at Texas A & M University . Rosenthal has worked in the Huasteca region of Mexico since 1994 and for years kept his research equipment at a local ranch/hotel with the dream of one day having a field station where he could run experiments with collaborators and students. Since 2005, Rosenthal has been the Co-Director of the field station along with his wife, Dr.

Eyes Underwater Watching Aquatic Wildlife
For as long as scientists have been studying the ocean, they have been limited by a lack of power. However, recent work from researchers at the University of Washington (UW) offers a promising new way to harvest energy from waves at sea. UW associate professor of mechanical engineering Brian Polagye spoke to EM about a recent project that used wave energy to power one of UW’s Adaptable Monitoring Packages, or AMPs. “Our work in this area has really been ongoing since about 2012,” explains Dr. Polagye. “We put our first prototype AMP in the water back in 2015. Since then, it’s been going through successive evolutions, variations on the package.
