The 5218 Wave & Tide Sensor is a compact fully integrated sensor for measuring wave and tidal conditions. The sensor is designed to be mounted on the Aanderaa SeaGuardII top-end plate or in other measurement systems using the RS-232 interface.
The sensor application areas are in fixed installations, either deployed in a seabed installation in shallow waters, or mounted onto a fixed structure in the upper water column. Typical applications for the sensor are meassurements of wave and tide in Ports and Harbours, Marine operations, Weather forecast and Climate studies.
The tide measurement is an average of the hydrostatic pressure measured over a time period of 10 seconds to 8 minutes (integration time configurable by the user). The update interval is between 1 second and 255 minutes. The wave meassurements are based on the pressure time series measured over a time period of 64 seconds to 17 minutes (configurable by the user). The update interval is between 1 second and 255 minutes.
The wave and tide sensor output parameters are Pressure, Tide Level, Tide Pressure, Temperature, Significant wave height, Maximum wave height, Mean period, Peak period, Energy wave period, Mean zerocrossing period, Wave steepness and irregularity of sea-state. Since all calibration and temperature compensation data are stored inside the sensor, the parameters are by default presented directly in engineering units without any external calculation. The sensor also provides raw data of the pressure and the temperature measurements.

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.

Onset HOBO RX3000 Remote Soil Monitoring Station
The Onset HOBO RX3000 Remote Monitoring Station is an environmental monitoring system that continuously logs data from compatible sensors that measure soil moisture, water level, temperature and various weather parameters. With numerous options for remote monitoring systems, Onset provides a Build-a-system configurator to help with ordering a system fit for any project’s needs. The configurator easily guides the user through the process of selecting different types of communication, power, sensor and other site-specific requirement selections when building their ideal system. The RX3000 ships with mounting plates and hardware, rubber cable channels, rubber plugs, grease, grounding wire and U-bolts.

Lake Malawi: A Treasure to Protect
Lake Malawi (also known as Lake Nyasa and Lake Niassa) doubles as a Rift Valley Lake and one of the seven African Great Lakes. Due to its unique biodiversity, it’s a great place to conduct limnological studies. Harvey Bootsma is a professor for the School of Freshwater Sciences at the University of Wisconsin-Milwaukee and has had an interest in limnology ever since he was a kid. Bootsma fondly recalls summer vacations to Georgian Bay, Ontario, “I probably spent as much time in the water as I did out of it.” He continues, "I remember telling myself, ‘I’m going to get a job where I can stay here all the time.’” While Harvey didn’t end up working on Georgian Bay, he was offered a job working on Lake Malawi. He continued working there while completing his Ph.D.
