How can I mount my wiper control housing?
The marine grade (316) stainless steel bracket attached to the wiper control housing can attach the housing to any required structure. Avoid attaching directly to a metal structure, as electrolysis can occur which may result in rapid deterioration of the metal parts.
How will I know when my Hydro-Wiper is low on battery?
When the battery reaches around 6.5 volts, the wipes will cease. The LED indicator will blink three times every 15 seconds when the Hydro-Wiper is in low battery shutdown mode.
How often should I set my Hydro-Wiper to wipe?
The optimal wipe interval will depend on the environmental conditions at the field site. Generally a wipe interval of 2 to 3 hours should prove sufficient. The wipe interval is controlled by the position of the wipe interval switch. The wipe interval switch can be set using the screwdriver provided in the field kit. Each position adds 15 minutes to the wipe interval, ranging from 15 to 720 minutes.
For decades, scientists have been fascinated by the color and clarity of water. Very high water clarity is extremely rare in nature. So it is was with some surprise that a team of scientists from the National Institute of Water and the Atmosphere in New Zealand recently discovered that Blue Lake, in Nelson Lakes National Park on the country’s South Island, is the visually clearest freshwater lake ever reported. Mark Gall, a scientist at NIWA, said colleague Rob Merrilees had seen Blue Lake and thought it could be comparable to Pupu Springs, another South Island lake that was the clearest reported freshwater at the time.Read More
The world is an unpredictable place full of fouling and entanglements that can send just about anyone astray. Water quality data too can be severely compromised by unforgiving conditions and unpredictable events. John Radford, Zebra-Tech’s founder, learned firsthand how fouling could degrade data quality to the point of being unusable. “Whilst working for the National Institute of Atmospheric Research in New Zealand, we had constant issues trying to make long-term measurements of suspended sediment concentrations in shallow coastal water,” he said. “Fouling of the sensors between site visits caused fatal degradation of the data quality. Attempts were made to develop a method for mathematically correcting the data, but these were unsuccessful.Read More
A complex series of locks and dams up and down the Ohio River enable interstate commerce, travel and recreation by maintaining a usable pathway for watercraft, but come with the inevitable byproducts of disrupting the river’s natural systems. To combat this, the U.S. Army Corps of Engineers uses a complex monitoring and response technology designed to minimize the negative impacts of dredging on the river ecosystem. Steven Foster, a limnologist with the Corps Water Quality Team, works at the Robert C. Byrd Lock and Dam in Gallipolis Ferry, West Virginia. He said one key area he focuses on is the welfare of mussels in the river. River dredging can smother mussel beds, so Foster and the team of engineers monitor the beds to ensure their safety.Read More
