All Bright Dyes

Details

Overview
Bright Dyes act as a coloring label on each drop of water. As that water or liquid travels, it can be identified at each point on its travel until it reaches extreme dilution. It may be detected visually, by ultraviolet light and by appropriate fluorometric equipment. The dyes selectively absorb light in the visible range of the spectrum. They are fluorescent because, upon absorbing light, they instantly emit light at a longer wavelength than the light absorbed. This emitted (fluorescent) light goes out in all directions. Most common fluorescent tracers are compounds that absorb green light and emit red fluorescent light.

Absorption Resistant
FWT red dye is resistant to absorption on most suspended matter in fresh and salt water. Compared to Bright Dyes FLT Yellow/Green products, FWT Red is significantly more resistant to degradation by sunlight and, when used in fluorometry, stands out much more clearly against background fluorescence.

Riding the Renewable Wave: Testing Wave Energy Converters at Oregon’s PacWave Site

Seven miles off Oregon’s weather-beaten coastline, the world’s biggest wave power testing facility, PacWave, is primed to put the latest renewable energy technology to the test. “There is a huge amount of energy that is not harvested in the ocean,” states the team at Oregon State University involved in the PacWave project. When it comes to harnessing the power of the waves, “It's exciting because it [wave power] is a non-polluting, non-carbon burning technology,” the team says. Wave Power The U.S. Energy Information Administration explains that tidal energy harnesses the flow of seawater in depth under the gravitational forces exerted by the sun and moon–the drivers of tides–while wave energy derives from the kinetic energy of wind-blown surface waves.

Source Water Monitoring: How Fayette County Finds the Highest Drinking Water Quality

Safe drinking water is vital for public health infrastructure, and providing cost-effective water treatment is a top goal of drinking water utilities. To reduce these costs, counties like Fayette, Georgia, rely on source water monitoring to evaluate water quality before it reaches the treatment plant. Fayette County Water System serves about 90,000 residents and pulls water from multiple reservoirs in the area. This variety of sources offers unique benefits for the county. They have built a system that minimizes cost and maximizes choice–two water treatment plants, multiple water pumps, and multiple reservoirs. Two of the reservoirs have intake structures that allow water treatment staff to choose which level of the water column has the best quality, within 2-foot increments.

A Powerful Solution? Buoys Tracking the Potential of Ocean Alkalinity Enhancement

The climate is a complex network of interconnected systems. Halting the cascading impacts of climate change is not as straightforward as cutting anthropogenic greenhouse gas emissions. Even if these emissions ceased entirely today, it would take many thousands of years for carbon dioxide (CO2) to return to pre-industrial levels. Removal of CO2 from the atmosphere is also necessary to keep global warming within the 2°C limit stipulated in the 2015 Paris Agreement . The Ocean as a Carbon Sink The ocean is the world’s largest carbon sink–it absorbs 30% of all carbon dioxide emissions and captures 90% of the excess heat generated by these emissions.
