PME miniDOT Logger: Plunge into Data

The PME miniDOT Logger is a compact data logger that measures dissolved oxygen (DO) and temperature down to 100 meters in depth. The unit can also endure low water temperatures and is durable underneath an ice layer, which is excellent for gathering essential winter water quality data that is lacking from using less robust equipment. The high depth rating and ability to withstand frigid temperatures make the PME a reliable device that is deployable in dramatically different environments, such as a monitoring well, an inland lake or an underwater cave. The logger itself features an optical DO sensor, temperature sensor, two AA lithium batteries and a micro SD memory card.

The Water of Life: How Understanding Natural Hydrologic Processes in Aquatic Ecosystems Can Lead to a Sustainable Future

From watersheds that provide drinking water, the rain that nourishes plants, to the streams and rivers that help aquatic ecosystems flourish, water is an ever-present and ever-essential part of life. For those like Durelle Scott, a professor of Biological Systems Engineering at Virginia Tech University, understanding the importance of these natural systems was always a part of life. The desire to preserve the nation's aquatic resources stems from a childhood spent exploring the lakes and streams that surrounded him growing up in rural Pennsylvania. Now, as a teacher and a researcher, Scott makes it a priority to ensure that people now and in the future appreciate the enormous impact that aquatic ecosystems have on their lives. “I would say that water connects us all.

Lufft WS800: Introducing A Station that Can Weather the Storm

The Lufft WS800 Multi-Parameter Weather Station measures a full suite of atmospheric parameters that provides all-encompassing data on the local environment, including a one-of-a-kind lightning detector. This compact, cost-effective sensor simultaneously measures air temperature, humidity, pressure, precipitation, solar radiation, lightning, and wind with an integrated electronic compass. An internal fan and heater reduce the effects of external influences for accurate measurements during long-term deployments. The sensor can be easily mounted on a 2-inch diameter pipe above any local obstructions with the included bracket mount, U-bolts, and 10-meter cable.  Settings for the unit can be adjusted using the latest UMB-ConfigTool.
