The NRG Marine Ultrasonic Antifouling System not only cleans a boat's surface below the water line, but it also destroys single cell organisms such as algae.
The NRG Marine Hull protection system utilizes the latest digital electronics and Ultrasonic transducer technology, by producing multiple bursts of ultra sonic energy simultaneously in a multiple range of frequencies. This energy produces a pattern of alternating positive and negative pressure.
The alternating pattern creates microscopic bubbles during periods of negative pressure and implodes them during periods of positive pressure in a phenomenon known as "cavitation." The implosion creates a micro-jet action that not only provides the cleaning effect on the hulls surface below the water line, it also resonates and destroys single cell organisms such as algae. The removal of the initial link in the food chain inhibits the growth barnacles and other marine life that feed on the algae.
Suitable for all types of hull materials except wood. The dual antifouling system is ideal for yachts up to 56 feet in length.

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
While the scientific community has formed its consensus on how ice sheets are shrinking in and around Greenland, some researchers are tracking what happens to the meltwater as it drains into the ocean each summer. Their study, published in Nature Geoscience by an interdisciplinary team of biologists, oceanographers and hydrologists, used computer models to simulate the meltwater to see where currents take it and what effect it could have on the ocean. Renato Castelao, one of the researchers and an associate professor of marine science for the University of Georgia, said one of the biggest discoveries of the study was the surprising final destinations of the ice sheets as they melt into the ocean each summer.Read More
Thinking of hitting the ice with a SondeCAM underwater fishing camera? Due to its rugged design, you won't have to worry about it handling the harsh elements. However there are a few simple tricks to get the most out of a FishSens SondeCAM while ice fishing. You won't have to do anything to modify the SondeCAM itself, but you are going to have to bring a few extra things. Most importantly we are going to need a power source. Unless you are hauling your gear with a truck, you'll want something more portable than the battery you used in the boat. Pick up an inexpensive and maintenance-free 12-volt, 9-amp battery. It is going to provide plenty of power, but will be much lighter and take up less space.Read More
