Overview
The Zebra-Tech LI-COR LI-192 Hydro-Wiper is a mechanical wiper system designed to fit easily to the LI-COR LI-192. Using a regular gentle brushing action, the Hydro-Wiper keeps the optical window of the LI-COR LI-192 clean from bio-fouling and other unwanted deposits such as mud. The Hydro-Wiper reduces the need for costly site visits to manually clean the instrument, maintaining data integrity throughout long deployments.
Self-Contained
The Zebra-Tech LI-COR LI-192 Hydro-Wiper consists of a wiper unit attached via a purpose-designed clamp. The wiper is connected to a rugged underwater housing, which contains the batteries, control electronics, diagnostic LED and wipe interval select switch.
Data Logger Controlled
The wiper is connected to the Hydro-Wiper control module by an electrical cable. To initiate a wipe, the data logger simply sends a trigger signal to the control module. Synchronizing the wipe with measurements ensures data quality is consistent throughout the deployment.

Lancaster County Makes the Switch to Real-Time Water Quality Monitoring Systems
Continuous data collection in Lancaster County, Pennsylvania, started about 5 years ago, and the county will be making a major upgrade over the next year—switching from relying solely on the internal storage of water quality sondes to telemetry units that enable real-time data viewing.

 Telling Lancaster County's Story Through Data 
Since the Lancaster County Conservation District started monitoring county waterways, the goal has remained the same, according to Amanda Goldsmith, Watershed Specialist for the Watershed Department.

In the early 2000s, along the coast of northern California, where the redwoods dominate the forests, and the Pacific Ocean shapes shorelines, a Humboldt University undergraduate student took the first steps into a lifelong love of marine biology. 
 
Dean Janiak accepted an invitation to help a graduate student with fieldwork in rocky coastal tide pools, and so began a journey that led him from California to Connecticut to Florida and eventually to the world, where he has facilitated research in communities across the globe. 
 
While finishing up his masters of Oceanography from the University of Connecticut, Janiak continued researching fouling communities–marine life that live on hard, often artificial surfaces such as docks–at the Smithsonian Environmental Research Center.

The Saint Croix Watershed is home to dozens of lakes, rivers, and streams that host an abundance of aquatic life from its tributaries. Valley Creek, a tributary of the St. Croix River, is a designated trout stream and while it is a pristine waterway, ongoing monitoring and stewardship establish a baseline of conditions and protect the creek. 
 
Don Wendel and Dllona Clendenen, Minnesota Master Naturalists, Liberal Arts majors, and retired college teachers, are two members of the wetlands research team based out of the Science Museum of Minnesota’s St. Croix Watershed Research Station that monitors Valley Creek throughout the year.
